EOL parts thread

Like I mentioned in bold, other manufacturers are still making this spec . STM is going to discontinue their thru hole spec.
 
Thought this might be the best place for this rather than a new thread. Received an email from Mouser today.

Does anyone care about this? Probably be inconsequential from a pedal building perspective, happy to provide the actual links if there is interest.

Helps to look at the datasheet to see what the spec and package are. That 4558DR is an SOIC package, but there's also a D (no R) that could still be in production. Same story with the TL072DR, I reckon.

Only one that is striking to my eyes is the MMBF5457 JFET. They dried up in TO-92 a while ago, and we've been flocking to the SMD with adapter boards since. The MMBFJ201 is similar, though not identical in spec, and that one is still around. The other JFET on there, J112 might be in some projects, but burning immediate comes to mind.

Another thing to look at is manufacturer. Hypothetical: TI might discontinue something, but STMicro might still carry it. STMicro are discontinuing many of their BAT4x diodes. Others will have them, but we do love the blue.

These are often just changes to the manufacturing process, datasheet or packaging, not necessarily EOL. Gotta dive into the actual info sheet by the manufacturer to determine whether this concerns us or not.

It's all pretty much that yeah. Just didn't want to create a new thread.

As a bass player, I rely on 2µ2 caps, a lot!

KEMET! Waht wur yoo theenking, MAHN⁉️

Seems like Kemet is discontinuing all film caps 2.2uF and up, see the following Mouser search: https://www.mouser.de/c/passive-components/capacitors/film-capacitors/?capacitance=2.2 uF~~6 uF&lead spacing=5 mm (0.197 in)&m=KEMET&rp=passive-components/capacitors/film-capacitors|~Capacitance

This is the EOL notice: https://www.mouser.com/PCN/YAGEO_PTN093025_VK_PTN_Mylar_Thin_film.pdf

As global as we are, it's interesting how a single plant makes the difference in the supply of what seems like a pretty high-volume product. This is probably the same film that hit WIMA large film caps, too. I wonder if there are actually issues running the PET film at the necessary thickness.

I work in specialty pharma - for over 20 years I developed transdermal patches - and even for market leaders, we were always at the mercy of suppliers to whom our volume was insignificant. Almost a decade ago the polymer for the most reliable non-metallic moisture barrier (polyacrylonitrile) stopped making the resin. This set off a scramble for everyone to find acceptable alterantives to replace the barrier in all kinds of pouched products.
No big deal, you might think, just switch to a foil multilaminate (which we used most of the time) - but there are situations (controlled substances in Japan) where you are required to visually count every unit of a product when you import it. So just using a foil barrier mutilaminate was not an option.
