DCPA10505D: Replacement from DCP010505D

Part Number: DCPA10505D
Other Parts Discussed in Thread: DCPA10505

Hi Team,

My customers are using DCP010505D. There was nothing wrong.

They are considering replacing DCPA10505D for price reduction.

I know that DCPA10505D is better withstand voltage, can the device be replaced without problems?

I would like to know the point to be careful when replacing.

Also, please give me the same information about DCP010505 and DCPA10505 of single output.

Best Regards,

Kenji

    Hi Kenji,

    I will have to take a look at it and get back to you on the benefits of using one over another.

    Hi Kenji,

    The DCPA10505D is pin to pin compatible with the DCP010505D device. I don't see any issues with using the DCPA10505D in your design. If anything the DCPA10505D device provides a higher operation isolation rating 2kVDC and slightly higher thermal shutdown at 168degC.

    Hi Jimmy-san,

    Thank you for your answer.

    I understood that there is nothing wrong replacing DCPA10505D.

    Can I think that single output is the same?

    Best Regards,

    Kenji

    Hi Kenji-san,

    Yes you can expect similar performance for the single output version. The single output version for both will regulate to 5V typical. 

    Hope this answers your question.

    Hi Jimmy-san,

    I appreciate your answer.
    Since customers judge carefully, please give me answer below.

    ① Release year / month of DCPA10505P-U/700 → Is it April 2017?
    ② Please tell us the reasons for development and the development concept.
    ③ Product positioning
    　DCPA10505P-U/700 is the successor to DCP010505DBP-U/700?
    ④ Is it possible to think that the characteristics at startup are the same as DCP010505DBP-U/700?
    　When designing the DCP 010505 DBP-U / 700, they confirmed the operation of sucking in a large current at startup.
    　And they have experience of failing to match with the power supply of the system.
    　They do not want to fail the same at DCPA10505P-U/700, so I would like to carefully judge the replacement.

    Best Regards,
    Kenji

    Hi Kenji-san,

    1) The devices in the DCPA1 family released in April 2017

    2) These devices have improved start-up performance than previous generation.

    3) DCPA1 is successor to DCP01

    4) The DCPA1 devices have improved start-up behavior which includes a soft-start feature that prevents high in-rush current during start-up.

    An EVM can be ordered to evalute the DCPA1 device at
