In design phase, do you require requestor to provide manufacturer's name and manufacturer's part number before you assign your internal part number?

Try ETA, www.etacbe.com, they do make custom made part if your requirements are not standard.

Thanks to both of you, I'll try to ask our design engineer if he could use TVS. I'll look for EPCOS and Littlefuse too.

Thanks Sreid! Keremsencan, yes I did search in google and sorry I didn't specify my question. I need a surface mount (if possible) or the smaller the better, low voltage. I found Sankosha and Bourns too. Are there any manufacturers?

Can someone help me find manufacturer of Spark Gaps. I'll appreicate any help. thanks

In our company, I'm using my own standard descriptions such as: Resistor (thru hole): Res type value tol power ex. Res MF 3ohm 1% 1/4W (MF for metal film) Res CF 3 ohm 1% 1/4W (CF for carbon film) resistor (surface mount) Res value tol power size Res 3ohm 1% 1/10W 0805 Capacitor...

Hi Kerem Thanks for the info, but they're not direct replacement. sordonyx

Does anybody know any manufacturers that have direct cross part for TI's UC3856DW, UC2845D8, UC2844D8, UC2854DW and UC2843D8, it can be Asian source. I found ON and ST as possible sources but their minimum temp is only -25C for the UC2843/44/45 and ON has B version while ST has A version...

Thanks csharp for the info!

Can I use metallized polypropylene X2 capacitor as an alternate for an X1 cap? or vice versa? What is the difference between the two? Please help. thanks

Thank you all!!!!

Hi Mike Thanks for the info. Do lead free components have identification when they are already in the power supply? Like if lead free resistors have a different color body part same as with the capacitors. And how about ICs do they have different logo on the package itself to identify lead free?

Thanks Melone and Keremsencan for the tips. Looks like I have to create new part numbers (for our internal use). By the way Keremsencan,we manufacture power supplies and therefore all the components in our power supplies (resistors, caps, ICs, FETs, connectors, etc) should be changed to lead...

We're in the process of converting our components to lead free. Does anybody know the best site regarding lead free components that can help me to start working with our part numbering system? Do I really have to create new parts numbers for all lead free components? I'll appreciate any help. thanks
