ROHS Fun

[LyleCaldwell]

Anyone know off the top of their head if there is an ROHS compliant replacement for the NTE177?  I've been datasheet diving so much I can't see straight, but I can't find anything suitable.

[RaceDriver205]

What is it?
Speaking of which, my effects machine will be the most ROHS non-compliant ever!

[nelson]

Now there is an oxymoron.

Try searching Farnell, or another RoHS dedicated site, to see what they have as a sub, then check if you can get it cheaper in your neck of the woods:

i believe nelson was referring to the subject title.

i also suspect that he's right.

If you stick to companies who only sell RoHS, or as good as, then it's not hard to be compliant...unless you're obsessed with LDRs!

Thanks - that points to a BAV20.  At first glance it seems like it might work.  I'll compare datasheets more closely when I'm more awake.

I think Newark in One are the US branch of this company.  They have some alliance at any rate as I get stuff from Newark via Farnell.  If you can't find any of the Farnell stuff locally at least you can get it from them.

PS  You can still get some non-compliant stuff from Rapid, Nelson (LDRs included).

I know, its not the problem. Its the complete lack of a direct replacement technology that irks me.

It doesn't make sense for a company to drop a popular line just because of RoHS, so it could just be that whatever you're having difficulty sourcing will become available in the near future (this has happened to me).  On the other hand, it's a great opportunity for manufacturers to dump 'non-productive' lines...

The problem is I had a great phaser design that I was looking to maybe sell.

Am I supposed to go (mos)fet?

I am working OTA right now, but its annoying. Sure you can appreciate that.

[gez]

Yes, that is a pain.  Darwinism has many forms!

I dont know legislating a darwinian nightmare is the answer.....


Anyway, adapting to legislation is not always evolving. It is often regressing in my opinion.

ROHS is a positive move but without viable replacement technologies it is regressing.

Even when it is something as simple as an LDR.

Can I add that the legislation is fundamentally flawed, its a step in the right direction but I dont see any actual change to the major consumer goods that are responsible for the main offending pollutants.

All I see is a change to the uncommon components that are much less likely to reach disposable status. But then again I am blinkered.

I do agree with your evolve or become extinct philosophy.

Its just a F'in nightmare.

I'm not having a hard time finding NTE177s.  I just can't use NTE177s in pedals shipped to Europe (and soon CA).  So I'm looking into comparable diodes that are ROHS compliant.

Have you taken the time to read the RoHS ?

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

Yes, I have taken the time to read ROHS legislaton and as far as I can tell it leaves LDR in a grey area. Without the green or the red light. I understand "without a viable replacement" however I am not prepared to take that risk Andrew.

Many technologies that are suppost to be directly affected by RoHS are in that situation but with the way the RoHS is written it shouldn't hinder those who have legitimate claims. From what I hear most if not all the LDR manufactures have applied and are expected receive exceptions. It is just a matter of the paper work so I am not worried.

I do not like to see gloom and doom preaching scenarios without any real justification. Nothing of the like has happened yet so chill and be cool. If you are not willing to take the risk then "adapt or die" rules apply.

Just my opinion.

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!
