Dear ti-Team,

I've got exactly the same problem finding sources for the LDT0666-50.

Alle there alternative Parts available?

    Hi Matthias,

    Thank you for your question.

    I am not aware of an alternate vendor for LDT0666-50. 

    Please accept my E2E friend request and I will provide you with contact information for Linkcom (LDT0666-50 vendor) via private message if you would like. 

    Thank you very much for your interest in Texas Instruments PoE products.

    Best Regards,

    Hello Matthias,

    The transformer is a 5V/5A output, which is fairly common. You can look at other reference designs with the same power requirements to see if there are already "off-the-shelf" products available now. 

    We have not verified other vendors for the TIDA-006617 design.

    Additionally, you can give the transformer spec sheet (available publicly link below) to another transformer vendor and request samples. If you get the same turns ratios and inductance you will probably get similar performance.  Then just depending on DCR and leakage will determine the thermal/efficiency performance. 

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
