Part Number: SN6505B
I'm looking for a second source of transformer part# 750313734 for new design of isolated dcdc using sn6505b.
which vendor do you recommend and part# pls ?
I need two transformer vendors minimum for production.
Thanks for using our E2E forums.
I understand your concerns. Sorry we don't have an exact alternative to the transformer #750313734, however for 5V (input) to 5V (output) use case, one can use the Coilcraft DA2303-AL transformer (link) or the Murata 782485/55C transformer (link) .
The turns ratio on these is a little higher (1:1.5 instead of 1:1.1 ), which means it can work across a wider range of input supply variations, at the expense of a little lower efficiency. Both designs should work for 100mA current levels without any issues, since the SN6505 has amply design margin on this front (1A capability).
Now, if you or the customer prefers a closer match for dual-source requirements for production, then one can contact other transformer vendors of choice such as Coilcraft, PCA, Pulse, Halo, Murata etc, to design a custom transformer to meet the end-application needs. One can ask for the specs desired and the vendors will be more than happy to generate a custom design and provide samples and a quote. usually they can do this is 3-5 weeks (typical, but varies from vendor to vendor) and we can help in this process. We also provide a detailed design guide in section 220.127.116.11 of the datasheet to help this process.
Hope this helps, best regards,
PS: A quick note on the links shared: These transformer products are generic and known to work across transformer drivers from TI as well as other vendors. Some of the product pages reference TI and others reference other vendors - just wanted to give you a quick heads-up on the same, so that you can decide how you wish to proceed.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Abhi Aarey:
does attached transformer a good fit for sn6505b ?
does the efficiency better - equal - or lower than #750313734 ?
