Engineering Selection Recommendations

The OPB882P51 is obsolete and no longer in active production. All listed substitute parts maintain full electrical and mechanical equivalence while offering active product status from TT Electronics/Optek Technology.

For new designs or ongoing procurement, OPB882T51Z is the direct manufacturer-recommended equivalent, offering ROHS3 compliance and active availability. This part shares the identical base product designation (OPB882) with the original component.

For applications where alternative base product numbers are acceptable, OPB360N51, OPB365N11, OPB365N51, OPB365P55, OPB370N51, OPB370N55, OPB375N51, OPB380N11Z, and OPB380P51Z provide functionally equivalent performance with ROHS3 compliance and active product status. All substitute parts maintain the same electrical ratings, sensing distance, through-beam configuration, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can OPB882T51Z directly replace OPB882P51 in existing designs?

A: Yes. OPB882T51Z maintains identical electrical specifications (50 mA forward current, 30 mA collector current, 30 V breakdown voltage), sensing distance (0.125"), through-beam sensing method, phototransistor output, and chassis mount pre-wired module form factor. The primary difference is active product status and ROHS3 compliance.

Q: What is the difference between OPB882T51Z and the other substitute parts listed?

A: OPB882T51Z shares the OPB882 base product number with the original part, making it the manufacturer-recommended direct equivalent. Other substitutes (OPB360, OPB365, OPB370, OPB375, OPB380 series) use different base product numbers but maintain identical electrical and mechanical parameters. Selection between these alternatives depends on availability and procurement requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status. The original OPB882P51 is RoHS non-compliant, making the transition to compliant alternatives necessary for regulatory adherence in new applications.

Q: Does packaging configuration affect substitution?

A: All substitute parts are supplied in bulk packaging with identical module, pre-wired form factor and chassis mount configuration. Packaging designation differences (such as "Z" suffix variants) reflect supplier packaging methods but do not affect electrical or mechanical compatibility.

Q: What inventory levels are available for these substitute parts?

A: Inventory varies by part number. OPB370N55 offers the highest availability at 90,400 units. OPB882T51Z provides 865 units, and OPB365N51 offers 1,916 units. Consult current stock status for procurement planning.
