Does anyone see an issue subbing the PMBS3906 and PMBS3904 in the Rockford amps instead of the MMBT3906 and MMBT3904?
They appear to be the same basic part.
One problem that I've found with a few of the Philips transistors is that they plastic they use melts easily. For example, you can heat 2 legs and lift them for testing with most SOT-23 transistors but some of the Philips just turn to goo when you try that. They use the same plastic on some of their TO-92 transistors as well.
I don't know why you're interested in using them unless you found them for cheap somewhere. I typically use the MMBTA06/56 as subs for those in Rockford amps.

I use both MMBTA56/A06 and MMBT3906/3904 just depends on what I decide to grab at the moment. I can pick up 10,000 of each for around $50 just thought it was a good deal, so would you not recommend getting them?
I've never had a problem with philips parts except for what I described. They will probably be OK as long as you know that they're from a reputable distributor. I don't use enough of anything to buy in that quantity. I buy in 500pc quantities (A06/56) and that typically lasts me 3-4 years.
