TLV2371-Q1: Inquiry about alternative use (TLV2371QDBVRQ1 vs. TLV271QDBVRQ1)

Part Number: TLV2371-Q1
Other Parts Discussed in Thread: TLV271-Q1, TLV9151, , TLV271, TLV2371, OPA314-Q1


The customer has developed the product by applying the current TLV2371QDBVRQ1.

Due to the problem of supply and demand, we are going to use TLV271QDBVRQ1 instead.

Are there any problems with alternative use?




  • The TLV271-Q1 has a slightly lower slew rate, and a slightly higher offset voltage. Its inputs do not go to the positive rail.

    There is no Q1 device that is perfectly compatible with the TLV2371-Q1. (Without Q1, I'd recommend the TLV9151.)

    Is it known what electrical characteristics are actually needed?

  • Hi MJ,

    The TLV2371 and TLV271 are very similar devices. Clemens has provided some of the spec differences. The main one being common mode voltage range.

    Does the customer have to us a 16V device? If not, they might consider using the TLV9061S-Q1 (would require a PCB redesign) or the OPA314-Q1.

    Thank you,

    Tim Claycomb

  • Hey MJ, 

    If they are open to a PCB redesign, the can always use the other package option available. 

    All the best,
