Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the OPB882P55Z. Selection criteria are based on product status and regulatory compliance:

OPB882T55Z is the manufacturer-recommended direct substitute, sharing the identical base product designation (OPB882) with the obsolete part. This part is in active production status and carries ROHS3 compliance with REACH unaffected status, making it the primary choice for direct replacement in existing designs.

The parametric equivalent parts (OPB360N51, OPB365N11, OPB365N51, OPB365P55, OPB370N51, OPB370N55, OPB375N51, OPB380N11Z, OPB380P51Z) are all active production parts from TT Electronics/Optek Technology with identical electrical ratings and environmental specifications. These parts are suitable for applications where the base product designation change is acceptable. All substitute parts maintain ROHS3 compliance and REACH unaffected status.

Inventory availability varies across substitute options, with OPB370N55 offering the highest stock level at 90,400 pieces, providing supply chain flexibility for high-volume requirements.

Frequently Asked Questions (FAQ)

A: Yes. OPB882T55Z is the manufacturer-recommended substitute with identical electrical specifications, sensing distance, output configuration, and operating temperature range. The primary difference is product status (active versus obsolete) and packaging designation (bulk versus module pre-wired configuration).

Q: What is the difference between OPB882T55Z and the parametric equivalents?

A: OPB882T55Z shares the same base product number (OPB882) as the original part. Parametric equivalents use different base product designations (OPB360, OPB365, OPB370, OPB375, OPB380) but maintain all critical electrical and mechanical parameters. Both groups are functionally interchangeable based on provided specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original OPB882P55Z.

Q: Does sensing distance remain constant across all substitutes?

A: Yes. All substitute parts maintain the 0.125" (3.18mm) through-beam sensing distance, ensuring compatibility with existing optical path designs.

Q: What are the current ratings for all substitute parts?

A: All substitute parts maintain identical current specifications: DC Forward Current (If) maximum of 50 mA and Collector Current (Ic) maximum of 30 mA, with Collector-Emitter Breakdown Voltage (VCE) maximum of 30 V.

Q: Is the operating temperature range the same for all parts?

A: Yes. All substitute parts operate across the identical temperature range of -40°C to 85°C, supporting the same environmental applications as the original OPB882P55Z.
