TPS23753A: TPS23753A PoE Transformer Alternative

Brl s.

Part Number: TPS23753A

Hi,

We are designing a circuit based on the TPS23753A and are using the TPS23753AEVM-004 schematic as a reference. However, the HA3801-BL transformer used in the reference design is currently unavailable in stock.

We are considering the following transformers as possible alternatives:

Pulse Electronics PA0691NL
Würth Electronics 750311806
Coilcraft C1173-AL

Would our circuit operate correctly if we used any of these transformers?
Additionally, could you please recommend any other suitable transformer models for this design?

Thank you in advance for your support.

Best regards,

Hi,

Thanks for reaching out.

The first and the third part you provided will be working fine.

I couldn't find the second part, please double check the part number.

One of our reference design uses LinkCom LDT0567-50.

Best,

Zhining

Hi Jack,

Thanks for mentioning this.

If HA3801-BL is available, you might go with it.

Thanks,

Hi,

Thank you for your support.

I have shared the datasheet for the 750311806 product. Could you please check it? Is it suitable for my application?
Also, could you share which reference design the LinkCom LDT0567-50 product is used in?
The winding configurations of the LDT0567-50 look different. Is it really compatible?

Hi,

According to the datasheet, 750311806 looks fine and should be working well.

LinkCom LDT0567-50 is used in PMP11107 reference design | TI.com. The winding configuration is similar and would also work.

You may choose between any of three you mentioned above. They should all be working fine.

Best,

Zhining

Hi,

We are unable to source the LinkCom LDT0567-50. Could you please recommend alternative (equivalent) parts for the HA3801-BL?
