I have been looking about (on the web and printed catalogs) attempting to replace a part that is now discontinued.
The experience has been part success - and part failure. A part is available to use if I update a board design to use a different package - but not a drop in replacement.
And so, I inquire - what is a the process or technique individuals in the electrical engineering field apply when they must replace/update a part/design with either of the following criteria:
- Equivalent replacement (you want to keep the same design or minimize changes to that design, e.g.; a discontinued part burned out - drop-in replacement).
- Complete redesign (you have a design that uses older parts - thru-hole components, etc - and you want to update that design with smd parts, but some of your old parts are discontinued and no obvious replacement part is available).
