How reliable is it to use another manufacturer's datasheet of the same part?

There is a part, 1N4148, or whatever from manufacturer A, but the datasheet from manufacturer B is more detailed, has nice graphs, etc. Is in general data for the exact part consistent between manufacturers?

How do you organize your datasheets?

I have probably a few hundred datasheets and app notes that I've collected for all sorts of parts in projects I've worked on. Previously, I used to keep these on a basic network share sorted maybe 2-3 folders deep by rough category, but then Google…

What does ND mean on part numbers?

I've come across a few parts that have ND at the end of their part number on Mouser and DigiKey. I can order the part with the ND at the end or not. What does that mean?

Should I indicate that beryllium compounds exist in a device?

Many years ago I built a power supply (an Elektor design) which used a 78HGKC voltage regulator. The data sheet explicitly said not to open the TO3 package as beryllium oxide (BeO) was used for thermal transfer. Today I learnt that BeO ceramic can…

What does the bar above a pin name in a datasheet mean?

This Serial Communications Controller from Zilog lists a few of its pins with a bar above the name. What does this bar mean? From a schematic I have been looking it seems a few of these are inactive when high and active when low?

Any advice on reading datasheets

After my embarrassing mistake by having the component in backwards, I'm wondering if anyone has advice for the newbie (or expert) on reading datasheets. What conventions are there which aren't obvious. What's the first thing you should check when…

What is the relevance of "typical values" in datasheets?

When working on a design I always work with minimum/maximum values from the datasheet (whichever is worst case), never typical values. I was reminded when in another discussion the leakage current for a BAS416 diode came up: 3pA typical, 5nA…
