Substitute Part Grouping Explanation

Substitute parts for the OPB880T11Z are identified based on strict parametric equivalence across the following critical criteria:

Electrical Specifications: Current - DC Forward (If) (Max) of 50 mA, Current - Collector (Ic) (Max) of 30 mA, and Voltage - Collector Emitter Breakdown (Max) of 30 V must match exactly.

Optical Characteristics: Sensing distance of 0.125" (3.18mm), through-beam sensing method, and phototransistor output configuration must be identical.

Mechanical & Environmental: Chassis mount configuration, module pre-wired package type, unamplified sensor type, operating temperature range, RoHS3 compliance, MSL 1 rating, and REACH unaffected status must align.

Manufacturing & Compliance: All substitute parts are manufactured by TT Electronics/Optek Technology and maintain active product status with identical regulatory certifications.

Substitute parts are grouped into two categories based on operating temperature range: parts rated -40°C ~ 85°C (full range equivalents) and parts rated -40°C ~ 80°C (reduced upper temperature limit).

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance identical to the OPB880T11Z. Selection between full-range temperature equivalents (OPB360N51, OPB365N51, OPB370N51, OPB370N55, OPB380P55Z, OPB390P11Z) and reduced-range temperature equivalents (OPB829AZ, OPB829CZ, OPB829DZ, OPB830W11Z) depends on application operating temperature requirements. For applications requiring the full -40°C ~ 85°C operating range, select from the first group. For applications with maximum operating temperatures at or below 80°C, either group is suitable. All parts carry identical electrical ratings, sensing characteristics, and regulatory certifications, ensuring direct functional interchangeability within their respective temperature specifications.

Frequently Asked Questions (FAQ)

Q: What determines if a part is a true substitute for the OPB880T11Z?

A: Substitute parts must match all electrical specifications (50 mA forward current, 30 mA collector current, 30 V breakdown voltage), optical characteristics (0.125" sensing distance, through-beam method, phototransistor output), mechanical configuration (chassis mount, pre-wired module), and compliance status (ROHS3, MSL 1, REACH unaffected). All substitutes are manufactured by TT Electronics/Optek Technology and maintain active product status.

Q: Can I use OPB829AZ, OPB829CZ, OPB829DZ, or OPB830W11Z in place of OPB880T11Z?

A: These parts are electrically and mechanically equivalent but have a reduced operating temperature range of -40°C ~ 80°C compared to the OPB880T11Z range of -40°C ~ 85°C. Use these substitutes only if your application does not require operation above 80°C.

Q: Are all substitute parts pre-wired modules?

A: Yes. All listed substitute parts are supplied as pre-wired chassis mount modules in identical package configuration to the OPB880T11Z.

Q: Do all substitute parts have the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, carry MSL 1 (unlimited) moisture sensitivity level, and maintain active product status.

Q: What is the difference between the various part numbers in the substitute list?

A: The differences are in the base product series (OPB360, OPB365, OPB370, OPB380, OPB390, OPB829, OPB830) and suffix designations, which indicate internal design variations. All maintain identical electrical and mechanical specifications for the OPB880T11Z application.
