Non-counterfeit LM3875T

[bcdzt5]

Fried my one of my LM3875. I'm trying to find a pair of LM3875, isolated or not, to replace mine. Any good non-counterfeit leads ?

Futurlec lists 'em. My guess is 50:50 chance they are at least high-quality copies. Delivery can be slow-boat.

Otherwise I don't see any that I would trust. Buying from well-known persons on *this* forum (who stocked-up and never got around to it) may be the best bet.

I've had good luck with B+D Enterprises in the past. They have the LM3875: LM3875 at B+D Enterprises

Do these new ones from B+D Enterprises look counterfeit?

The silkscreening or laser etching is considerably different than the original 3785.

While I recognize this is a different package suffix, I'm surprised NS (or TI) would use different marking types across these chips. It caught me off guard.

The vendor has assured me they're National Semiconductor chips. The one I've soldered in so far sounds good.
