Substitute Part Grouping Explanation

Substitute parts for the OPB882T55Z are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

Sensing Distance: 0.125" (3.18mm)
Sensing Method: Through-Beam
Output Configuration: Phototransistor
Current - DC Forward (If) (Max): 50 mA
Current - Collector (Ic) (Max): 30 mA
Voltage - Collector Emitter Breakdown (Max): 30 V
Mounting Type: Chassis Mount
Package / Case: Module, Pre-Wired
Type: Unamplified
RoHS Status: ROHS3 Compliant
REACH Status: REACH Unaffected

All identified substitute parts match these parameters. Operating temperature ranges vary between -40°C ~ 85°C and -40°C ~ 80°C; parts with -40°C ~ 80°C operating range are suitable for applications not requiring the extended upper temperature limit of 85°C.

Engineering Selection Recommendations

All substitute parts listed are Active status products from TT Electronics/Optek Technology and maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the OPB882T55Z.

Parts OPB360N51, OPB365N51, OPB370N51, OPB370N55, OPB380P55Z, and OPB390P11Z maintain the full operating temperature range of -40°C ~ 85°C, matching the OPB882T55Z specification. These parts are direct functional equivalents for applications requiring the extended upper temperature limit.

Parts OPB829AZ, OPB829CZ, OPB829DZ, and OPB830W11Z operate within -40°C ~ 80°C. These parts are suitable for applications where the maximum operating temperature does not exceed 80°C. Selection of these parts should be based on application temperature requirements.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the OPB882T55Z?

A: Substitute parts must match all critical electrical and mechanical parameters: 0.125" (3.18mm) sensing distance, through-beam sensing method, phototransistor output configuration, 50 mA maximum forward current, 30 mA maximum collector current, 30 V maximum collector-emitter breakdown voltage, chassis mount configuration, pre-wired module package, and unamplified type. All parts must maintain ROHS3 compliance and REACH Unaffected status.

Q: Can I use OPB829AZ, OPB829CZ, OPB829DZ, or OPB830W11Z in place of OPB882T55Z?

A: These parts are electrically and mechanically equivalent but operate at -40°C ~ 80°C instead of -40°C ~ 85°C. Use these parts 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 modules in chassis mount configuration, matching the OPB882T55Z package type.

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

A: Yes. All substitute parts are ROHS3 compliant and REACH Unaffected, matching the OPB882T55Z compliance status.

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

A: The part numbers reflect different internal configurations or manufacturing variants within the OPB series. All listed parts meet the same electrical and mechanical specifications for substitution purposes. Differences in part numbering (such as OPB360, OPB365, OPB370, OPB380, OPB390, OPB829, OPB830 base numbers) indicate different product lines within the through-beam phototransistor module family, but all maintain parameter equivalence for this application.
