Is IC power pin position (V+ / V-) for a package mostly standardized for opamps, comparators, INAs etc.?
Is the power pin position for certain types of ICs standardized or practically, mostly standard? I assume there are rare exceptions and manufacturers could do what they want, but the general answer to ...

What can I do about using incorrect P-FET package?
I just got a PCB in I designed from fab, and I quickly discovered I made a mistake in the design. I'm using a P-channel MOSFET, D2PAK, as a high-side switch.
Its pinout is (1) gate, (2) drain, (3) ...

Is APDS-9253 pinout really inverted?
I'm drawing the footprint for APDS-9253 and in the datasheet I'm looking at package drawings.
As far as I understand, the top-left drawing is a view from component side, the top-right one from solder ...

First pin of TXS0102DCUR
I bought some TXS0102DCUR, and I am not 100% confident that the first pin is from the side of the stripe (left side, relative to the picture). Could anyone confirm, please? I scanned through the ...

Identifying pin 1 of Analog Devices REF195
I have the Analog Devices REF195GSZ, and it doesn't have a circle on either the top or bottom by a pin to indicate pin 1.
Looks like this:
Which is pin 1? The datasheet didn't seem to help either: ...

Why do single op-amp DIP packages have 8 pins, rather than 6?
Single op-amps often come in 8-pin DIP packages, with 5 of those pins being standardized (or maybe it's just de-facto) like in the ones below.
(source: linear.com)
Older op-amps such as the LM741 (...

Why are the collector and emitter on this TO-92 transistor reversed?
Every TO-92 BJT I've ever seen reads collector-base-emitter when read left-to-right facing the flat side. Then I found this lovely part, BC517. It reads emitter-base-collector.
Have I only been ...

BEC or CEB NPN Transistor [closed]
I am looking for a small, inexpensive NPN transistor, similar to 2N4401 in specs, with a BEC or CEB pinout.
Does anyone know of any?

How to explain this difference in pinout?
Seemingly illogical pinout has been discussed before, but my question is different.
Have a look at the pinouts for the Si8540:
One would think that the pin order would be the same for both packages,...
