What is the difference between different chip suffixes? [Copy link]

 

For example, LM7812 has CT, ACT, and L-TA3-T? ? ?

It generally represents information such as packaging, accuracy, temperature range, etc. The specific classification description can be found in the chip specification sheet.

Generally speaking, the differences refer to packaging, operating temperature range, certain parameters, and the presence or absence of certain functions. You must read the device manual to determine and cannot guess.

Some models have multiple manufacturers. Even if they are fully compatible, the suffixes of each manufacturer may be the same or different. Therefore, in this case, you need to check the device manual to confirm. In short, everything is subject to the device manual. Read it in full, read it carefully, and read it clearly.

Each manufacturer is different, so it is best to read the manual. The last few pages will usually indicate what it means. For example, different wafer versions (A, B, C, etc.), different working ranges (commercial, industrial, military, automotive, etc.), different packages (SOP, DIP, TO, SOT, etc.), and different packaging (tube, taping) will all be clearly marked in the manual.

The suffix may indicate the package, accuracy, operating temperature range, etc. Different packages will of course have different heat dissipation powers. For example, the LM317L is much smaller than the LM317, and has much less heat dissipation power. You can only find out the details by checking the chip manual.

Look at the manufacturer's specification sheet, which is usually written

It represents the minimum package, packaging method, temperature level, accuracy level, etc. You must carefully compare the specifications.

The specification sheets all have some information about what the different suffixes mean. You can find out by looking at the naming rules in the specification sheets.

There are differences in packaging, accuracy, operating temperature, etc. Read more information. As shown in the figure below, the manual explains it very clearly.

The explanations above are very accurate, specific, precise, and thorough. You must read it carefully. The performance impact is relatively large. The host should pay attention. A large number of people changed it because of the label problem.

Yes, you have to pay attention to products from different manufacturers. I used to use a TL431 and our supplier's BOOM list said it was a specific product from TI, but the supplier didn't follow the requirements. As a result, I found that two pins were different from TI's package. It took me two days of debugging to discover this.
