Substitute Part Grouping Explanation
Substitution eligibility for the OPB993P55 is determined by electrical and mechanical parameter equivalence across the Photologic® optical sensor family. All substitute parts maintain identical specifications for sensing distance (0.125"), sensing method (through-beam), output configuration (NPN open collector inverted), mounting type (chassis mount), supply current (15 mA), supply voltage range (4.75V–5.25V), response time (70ns), operating temperature range (-40°C to 70°C), and package type (module with wire leads). The primary distinction between the main part and substitutes is product status: the OPB993P55 is obsolete, while all listed substitutes are active production parts. Additionally, substitute parts comply with ROHS3 standards, whereas the OPB993P55 is RoHS non-compliant. All parts share the same ECCN (EAR99) and HTSUS classification (8541.49.8000).

Engineering Selection Recommendations
All listed substitute parts are functionally equivalent to the OPB993P55 based on electrical and mechanical specifications. The primary selection criteria are product status and regulatory compliance. All substitute parts are active production components with ROHS3 compliance, ensuring long-term availability and adherence to current environmental regulations. The OPB993P55, being obsolete and RoHS non-compliant, should be replaced with an active equivalent for new designs or production continuity.
OPB983T51Z offers the highest inventory availability at 20,199 units, providing supply security for high-volume applications. OPB983L51Z and OPB983P51Z provide substantial inventory levels (1900 and 2108 units respectively) with active product status. OPB933W51Z and OPB933W55Z represent the OPB933 base product family with active status and ROHS3 compliance.

Q: What is the difference between the OPB993P55 and the substitute parts?
A: The OPB993P55 is an obsolete product with RoHS non-compliant status. All substitute parts are active production components with ROHS3 compliance. Electrical and mechanical performance parameters are equivalent.
Q: Why should I transition from OPB993P55 to an active substitute?
A: The OPB993P55 is obsolete, which creates supply chain risk for future production runs. Active substitute parts ensure continued availability, support for new designs, and compliance with current environmental regulations (ROHS3).
Q: Are there packaging differences between substitute parts?
A: All substitute parts use identical packaging: module with wire leads, suitable for chassis mount applications. Packaging is listed as bulk for all active substitutes.
Q: Which substitute part has the best inventory availability?
A: OPB983T51Z has the highest inventory level at 20,199 units, followed by OPB983P51Z (2108 units) and OPB983L51Z (1900 units).
Q: Do all substitute parts comply with ROHS3?
A: Yes. All listed substitute parts are ROHS3 compliant. The original OPB993P55 is RoHS non-compliant.
