I tried to buy from NTE directly but was informed I had to purchase through a local distributor, Why?View Answer.

In the past, NTE was only set up to sell through it's network of distributors. However, with the addition of our new on-line division, you can now order your NTE components directly from us. Visit our new on-line ordering division at:  www.ntepartsdirect.com.

I called my local distributor for a particular item but they did not have it in stock. I need it urgently! What should I do?View Answer.

Getting you the correct parts when you need them is our main goal. Ask your NTE distributor to place a drop shipment order for you. The item you need can be delivered to your location the very next day via UPS Red or a similar next day freight service. Or, you can visit NTE's new on-line components division at:  www.ntepartsdirect.com.

I'm having trouble with the QUICKCross download form. After filling it out and clicking on the "Submit" button, I keep getting asked to re-enter all of my information. Is there a problem?View Answer.

No. Unfortunately, the form DOES NOT WORK with older version of the Internet Explorer web browser. We recommend that you use IE10 or newer, or you can use another web browser such as Firefox, Google Chrome, etc.

I have your QUICKCross software. If I put in the NTE device number, will it give me all of the part numbers that cross to it?View Answer.

No. QUICKCross is not designed to work in a reverse manner. Although one NTE device will replace many original devices, the same does not hold true that the original device will be as good as the NTE. This is because in many cases NTE uses a device with much better electrical specifications to replace the original device thereby upgrading your circuit.

After installing QUICKCross, I click the icon and receive the NTE logo and then the screen disappears. Why?View Answer.

NTE's QUICKCross software is designed to "remember" the last state the program was in the last time it was run. For example, if you maximized the screen the last time you ran the program, the next time you launch the program, the screen will be maximized. The same holds true if you minimized the program and exit windows without maximizing and closing the program. The next time you try to run the program it will load, minimize, and exit. To solve this problem you would right click on the "Start" button and select "Explore". From there, go to your "Windows" directory and look for a file called "nteQCxx.INI" (replace "xx" with the corresponding QUICKCross version number). Delete this file and close the explore window. You can now run the QUICKCross program.

I cannot locate datasheets for TTL and CMOS type devices anywhere on your website. Why?View Answer.

At this time, NTE does not offer datasheets for generic industry standard device numbers. This applies to the following NTE series types: 7400, 74C, 74H, 74HC, 74HCT, 74L, 74LS, 74S, 74000, 75000, 4000, 4500, and 40000.

Where can I find application notes, typical applications circuits, test circuits, schematics, internal diagrams, and characteristic curves for NTE devices?View Answer.

NTE device datasheets do not contain any of this information or any other information affiliated with new circuit design. The information contained within these datasheets are standard electrical characteristics intended to assist the user in selecting the correct NTE device for use in an already existing, working circuit.

How do I interpret the date codes stamped on NTE devices?View Answer.

The first two numbers represent the last 2 digits of the year, For example, "07" would indicate the year 2007. The third number represents which week (first, second, third, fourth) of the month. And lastly, the letter at the end represents the month (A, B, C, D, E, F, G, H, J, K, L, M represent Jan thru Dec respectively).

When using NTE's on-line datasheet search, do I need to add "LF" to the device number to find the correct datasheet?View Answer.

No. The letters "LF" are not a part of the NTE device number. They are just an indication that the device is RoHS compliant.

How do I determine the location of "Pin1" on NTE's SIP and DIP type IC packages?View Answer.

There are four (4) different "Pin1" locators (half-circle, circle lower left, bottom beveled edge, & left-side beveled edge)associated with NTE's SIP and DIP type IC packages. An example of each type is shown in this document.

While running QUICKCross on a machine using the Windows Vista operating system, I cannot view the "Help" file. Why is this?View Answer.

Windows Help (WinHlp32.exe) is a Help program that has been included with Microsoft Windows versions starting with the Microsoft Windows 3.1 operating system. However, the Windows Help program has not had a major update for many releases and no longer meets Microsoft's standards. Therefore, starting with the release of Windows Vista, the Windows Help program will not ship as a feature of Windows. If you want to view 32-bit .hlp files, you must download and install the program (WinHlp32.exe) from the Microsoft Download Center.

I'm having trouble installing and running QUICKCross on a machine using the Windows 98 & Windows 2000 operating systems. Why is this?View Answer.

Unfortunately, while testing the BETA version of QUICKCross 14, we discovered that it does not always work with Win98. There is a file (gdiplus.dll) missing in older Windows operating systems that prevents the program from functioning properly. This file is added during the installation, however the program still does not always function properly.

Therefore, in future releases, we are only recommending that the program be run on newer Windows operating systems (WinXP, Vista, etc).

What is the difference between Functioning Temperature, Holding Temperature, and Maximum Temperature on the NTE Thermal Cutoff (TCO) Data Sheet?View Answer.

Functioning Temperature is the temperature at which the TCO will trip, Holding Temperature is the maximum continuous temperature the TCO can withstand without premature failure, and Maximum Temperature is the maximum temperature that the TCO can withstand without physically changing state.

For a relay switch, what is the difference between resistive, inductive, motor, and lamp loads?View Answer.

We must express the load as a contact rating, which is the electrical load-handling capability of relay contacts under specified conditions and for a prescribed number of operations or life cycles.

Resistive Load: A resistive load usually consists of some sort of resistance in the circuit; e.g., heaters, resistors, etc.

Inductive Load: An inductive load consists of a load created by a wire wound coil, such as in a relay or solenoid, a transformer, or any load which uses a winding over a magnetic iron core. Breaking an inductive load is usually more severe than breaking a resistive load and will generally produce heavy arcing.

Motor Load: A motor load can be referred to as a rotating inductive load, generally with a high inrush of six times the normal load. The breaking of the load is much the same as a resistive load.

Lamp Load: There are many types of lamp loads such as tungsten filament, fluorescent, mercury-vapor, and other exotic gas lamps. The loads we normally concern ourselves with are tungsten filament. Tungsten filament lamps, when first turned on, will draw an inrush current of 10-15 times of the steady-state current. The inrush is similar to a motor load inrush and is caused by the cold filament in the lamp. After the lamp filament has heated up, the current will drop to its normal level. Most tungsten filament lamp load ratings are 20% of a resistive load.
