Substitute Part Grouping Explanation

Substitute parts for the OPB982T55 are qualified based on strict electrical and mechanical parameter matching. All substitute parts maintain identical specifications across the following critical parameters: sensing distance (0.125" / 3.18mm), sensing method (through-beam), output configuration (totem pole inverted), mounting type (chassis mount), supply current (15mA), supply voltage range (4.75V ~ 5.25V), response time (70ns), operating temperature range (-40°C ~ 70°C), and package type (module with wire leads). All substitute parts are manufactured by TT Electronics/Optek Technology within the Photologic® series.

The primary distinction between the main part and substitutes is product status: OPB982T55 is obsolete, while all listed substitutes maintain active product status. Additionally, substitute parts comply with ROHS3 standards, whereas the original part is RoHS non-compliant. This compliance upgrade represents the only functional difference in the component specifications.

Frequently Asked Questions (FAQ)

Q: Can OPB982T55 be directly replaced with OPB982T55Z?

A: Yes. OPB982T55Z is the direct equivalent with identical electrical and mechanical specifications. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant). Packaging differs only in designation (bulk versus module wire leads), with no functional impact on component performance.

Q: What determines compatibility between OPB982T55 and its substitutes?

A: Compatibility is determined by matching specifications across sensing distance (0.125" / 3.18mm), sensing method (through-beam), output configuration (totem pole inverted), supply voltage (4.75V ~ 5.25V), supply current (15mA), response time (70ns), operating temperature range (-40°C ~ 70°C), and package type (module with wire leads). All listed substitutes meet these criteria.

Q: Are there differences between OPB982, OPB932, OPB942, and OPB992 base product families?

A: All substitute parts listed maintain identical electrical and mechanical parameters specified for the OPB982T55. Base product family designation reflects internal TT Electronics/Optek Technology product architecture but does not affect functional compatibility for this application.

Q: What is the significance of the suffix letters and numbers in part numbers like T55Z, P51Z, or W55Z?

A: Suffix designations indicate specific product variants within the Photologic® series. All variants listed maintain identical specifications for sensing distance, sensing method, output configuration, supply parameters, response time, and operating temperature. Suffix differences do not impact functional substitution capability.

Q: Should packaging type (bulk versus module wire leads) affect substitution decisions?

A: Packaging designation reflects distribution format rather than component functionality. All substitute parts maintain identical module with wire leads physical configuration and electrical performance. Bulk packaging designation indicates standard distribution format without affecting component specifications or compatibility.

Q: Is ROHS3 compliance required for substitution?

A: ROHS3 compliance is a regulatory and environmental consideration. All active substitute parts listed are ROHS3 compliant, representing an improvement over the original OPB982T55 (RoHS non-compliant). This compliance upgrade is beneficial for new designs and regulatory adherence.
