Engineering Selection Recommendations

All substitute parts listed are manufactured by TT Electronics/Optek Technology and maintain active product status. Each part carries ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility with the OPB882T51Z.

Substitute parts with -40°C to 85°C operating temperature range (OPB360N51, OPB365N51, OPB370N51, OPB370N55, OPB380P55Z, OPB390P11Z) provide identical thermal performance to the main part. Substitute parts with -40°C to 80°C operating temperature range (OPB829AZ, OPB829CZ, OPB829DZ, OPB830W11Z) are suitable for applications where the maximum operating temperature does not exceed 80°C.

All parts share identical electrical specifications: 50 mA maximum forward current, 30 mA maximum collector current, and 30 V collector-emitter breakdown voltage. Mechanical compatibility is maintained across all substitutes through identical chassis mount configuration and pre-wired module packaging.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the OPB882T51Z?

A: Substitution is based on matching sensing distance (0.125"), sensing method (through-beam), output configuration (phototransistor), electrical ratings (50 mA If, 30 mA Ic, 30 V VCE), mounting type (chassis mount), and package format (module, pre-wired). All substitute parts meet these criteria.

Q: Can I use OPB829AZ, OPB829CZ, OPB829DZ, or OPB830W11Z as direct replacements?

A: These parts are functionally equivalent for applications operating within the -40°C to 80°C temperature range. If your application requires operation above 80°C, use substitute parts with -40°C to 85°C ratings instead.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, matching the OPB882T51Z environmental specifications.

Q: Do substitute parts require circuit redesign?

A: No. All substitute parts maintain identical electrical performance parameters and mechanical form factors. Direct pin-for-pin and functional replacement is supported without circuit modification.

Q: Which substitute part has the highest inventory availability?

A: OPB370N55 has the highest inventory with 90,400 pieces in stock, followed by OPB829DZ with 5,613 pieces.
