Q: What is the difference between the substitute part numbers?

A: Substitute parts differ in base product series (OPB360, OPB365, OPB370, OPB375, OPB380, OPB880) and packaging designations (N11, N51, N55, P55, P11Z, P55Z, P51Z). All maintain identical electrical and mechanical parameters specified for through-beam optical sensing at 0.125" (3.18mm) distance.

Q: Why is OPB380P11Z classified as obsolete?

A: The original part number OPB380P11Z is no longer in active production. Active alternatives with identical specifications are available from the same manufacturer to support legacy system maintenance and new designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original OPB380P11Z.

Q: Which substitute offers the best supply availability?

A: OPB370N55 provides the highest inventory level at 90400 Pcs, followed by OPB880P51Z at 5415 Pcs. Both support high-volume production requirements.
