Ryan,
I find it ironic that Verizon continues to ask that you keep the Pb in when,
but as we all know these past few years, we have great difficulty in getting
parts that are tin-lead plated.
Every day purchasing tells me of yet another part that is now unavailable and
we must find a substitute only to find that the so-called "substitute" is
lead-free. Only recently on one part from Analog Devices, did the converse
hold true. The distributor quoted 16 weeks and I blew a gasket. Turned out
they had quoted the lead-free part which we had not requested a quote on!
Finally the truth came out - we could have the leaded part in 5-6 weeks
(standard delivery terms). I was not amused.
Until we can find a way to force parts manufacturers to make them go back to
tin-lead solder plating parts, sure, we'll solder the parts down with tin-lead.
But tin whiskering will happen above the solder wetting point and we will have
reduced reliability.
Is Verizon willing to pay you what NASA and DOD pays for parts that get
recoated in tin-lead, one at a time?
I doubt it.

Hello John,
I know I am a little late on this thread but I am sure this is still Verizon's
position.
It was my suggestion during the Q&A session at Verizon's NEBS 2006 conference
that produced this statement on their website. (Pat pat..)
Verizon does have a need for RoHS compliant products for their foreign
deployments but there too they ask we keep the Pb as there is an exemption for
telecommunication products.

I have written to Telcordia to find out. I doubt the position has changed.

Bob,
This is 18 months old, and component suppliers continue to convert to pure tin.
Do you know if this is still the Telcordia position. Sure would be nice to
try to bolser some similar resolve in the military community.

Verizon Supports Telcordia's Position on the RoHS Directive
New legislation known as "RoHS" (Reduction of Hazardous Substances) bans
certain chemicals and metals from some electronic manufacturing. In order to
maintain high and predictable network reliability, it is the expressed desire
of Verizon that:
. 1. Equipment manufacturers shall continue to use leaded-solder until
alternatives have demonstrated reliability suitable for the telecommunications
infrastructure, and;
. 2. Component suppliers shall continue to make available components
compatible with leaded-solder manufacturing until alternatives have
demonstrated reliability suitable for the telecommunications infrastructure.
Verizon supports the position conveyed by Telcordia in their Notice To The
Industry. Click here to view this document.
