Engineering Selection Recommendations

The OPB882P55 is classified as obsolete and carries RoHS non-compliant status. All listed substitute parts are active products with ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards.

For direct replacement with manufacturer-recommended status, OPB882T55Z is the primary substitute. This part maintains identical electrical and mechanical specifications while offering active product support and improved regulatory compliance.

For parametric equivalents with extended inventory availability, OPB370N55 provides the highest stock level (90,400 units) while maintaining all critical electrical parameters and operating characteristics. OPB365N51 and OPB365P55 offer additional parametric equivalence with substantial inventory support.

All substitute parts are manufactured by TT Electronics/Optek Technology and maintain the same sensing distance, through-beam detection method, phototransistor output configuration, current ratings, voltage ratings, temperature range, and pre-wired chassis mount packaging as the original OPB882P55.

Frequently Asked Questions (FAQ)

Q: Can OPB882P55 be directly replaced with OPB882T55Z?

A: Yes. OPB882T55Z is the manufacturer-recommended substitute with identical electrical specifications (50 mA forward current, 30 mA collector current, 30 V breakdown voltage), operating temperature range (-40°C to 85°C), sensing distance (0.125"), through-beam sensing method, phototransistor output, and pre-wired chassis mount packaging. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

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

A: OPB882T55Z is the manufacturer-recommended direct substitute for the OPB882P55. Parametric equivalents (OPB360N51, OPB365N11, OPB365N51, OPB365P55, OPB370N51, OPB370N55, OPB375N51, OPB380N11Z, OPB380P51Z) share identical electrical and mechanical parameters but differ in base product number and internal design characteristics. All maintain the same sensing distance, output configuration, current ratings, voltage ratings, and operating temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, whereas the original OPB882P55 is RoHS non-compliant. This compliance improvement is a key advantage of transitioning to active substitute parts.

Q: What inventory levels are available for substitute parts?

A: OPB370N55 offers the highest availability with 90,400 units in stock. OPB365N51 provides 1,916 units, OPB360N51 provides 1,394 units, OPB370N51 provides 1,250 units, OPB365P55 provides 1,052 units, OPB882T55Z provides 760 units, OPB365N11 provides 658 units, OPB375N51 provides 648 units, OPB380P51Z provides 651 units, and OPB380N11Z provides 1,100 units.

Q: Do all substitute parts maintain the same pre-wired packaging?

A: Yes. All substitute parts are supplied as pre-wired modules with chassis mount configuration, maintaining identical form factor and installation compatibility with the original OPB882P55.

Q: What are the critical parameters for substitution?

A: Substitution eligibility is determined by: sensing distance (0.125"), sensing method (through-beam), output configuration (phototransistor), forward current rating (50 mA max), collector current rating (30 mA max), breakdown voltage (30 V max), operating temperature range (-40°C to 85°C), mounting type (chassis mount), package type (module, pre-wired), and amplification type (unamplified). All listed parts maintain these parameters identically.
