PN2222 VS KSP2222

[altec9440]

Hi friends,

seems that standard 2N2222 with metal can had disappeared. (I mean brand parts, not indefined clone).

Between PN2222 and KSP2222, what would be a good choice ?

Have a nice day

Multicomp do them. BTW 2N2222A is preferred over 2222 for switching, more power, more current.

Farnell have only 73,852 in stock and a mere 407,595 for the A type. Multi comp, the manufacturer, has no plan for obsolescence.

On Semi's datasheet for KSP2222A says "Available as PN2222A"

Unless I had some well-defined reason to prefer the metal can, I'd probably choose these or similar from any other large foundry than the metal can part from a small one.

A 2222 is pretty generic. What’s the application?

Multicomp is a commercial resell brand not a fondery. Clones are not full caracterised (see light datasheets) and not under originals lists (ESA, Mil, automotive).

Seems that PN have slightly better switching caracteristics.
