ROHS Fun

[LyleCaldwell]

No self respecting builder would use NTE parts in anything for production as NTE are not a parts manufacture but a part relabeller/supplier and would never be able to guaranty you anything including RoHS compliance. Use real part manufactures. Find out what the original part is and search for that.

Andrew,
Why the attitude?  The original part is a 1S1555, which isn't carried by Mouser or Digikey.  Mouser sells the NTE177 as a modern replacement for the 1S1555.  I've been using the NET177 just fine, but now must find an ROHS compliant sub.

Not that I don't enjoy a(nother) spirited RoHS discussion as much as anyone, but let me hijack for just haffa mo' - NTE177 evidently cross-references to the MPD400 forward reference diode by Microsemi and its replacement, the CMPD400 from Central Semiconductor. Both companies purport to be producing RoHS-compliant lines of their respective products - you might contact them for availability info. Please excuse the interruption - gentlemen, pray, continue! 

Thanks very much, lovekraft.  Mouser and Digikey don't stock those, but I'll see if I can find a source, if they are ROHS-compliant.  Mouser lists the CMPD400 as "In Transistion" when it comes to ROHS, so it may be a matter of months.

No attitude just biz advice. As I stated NTE does not produce parts themselves or atleast not many. They take parts, relabel them, and sell them at an increased price to you. You can never be sure what part they are really selling you as they have very loose standards. My real concern for you is that one day you receive an order of their parts and they do not meet your needs because they changed the part that they are relabelling. Now you have serious trouble. Using a real part from a manufacture will help relieve that concern. Also it will be cheaper as you won't get hit with NTE's markup for their relabelling effort.

A better idea would be find the specs of that particular part that are important to the circuit and find another current and compliant part. It is really much better for you in the end.

Good luck.

That's what I'm trying to do.

I've heard of a number of nightmares with NTE parts where relabeled chips with lower than advertised specs were sold as something else. You will see all kinds of differing parts under the same NTE stock number.

who is NTE, btw?
