Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the OPB992P55Z. Selection should prioritize active product status parts to ensure long-term supply continuity and support. OPB992P51Z and OPB992N55Z offer the highest inventory availability within the OPB992 base product series. OPB982 and OPB932 series alternatives provide equivalent functionality across all specified parameters while maintaining ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can OPB992P51Z directly replace OPB992P55Z? A: Yes. Both parts share identical electrical specifications (15 mA supply current, 4.75V–5.25V supply voltage, 70ns response time), mechanical configuration (0.125" sensing distance, through-beam, totem pole inverted output, chassis mount, wire leads), and compliance certifications (ROHS3, REACH unaffected). The primary difference is product status: OPB992P55Z is obsolete while OPB992P51Z is active.

Q: What distinguishes parts within the OPB992, OPB982, OPB942, and OPB932 series? A: All listed parts maintain identical sensing distance, sensing method, output configuration, supply current, supply voltage, response time, operating temperature range, and compliance status. Differences exist only in base product number designation and specific packaging or lead configuration codes embedded in the part number suffix.

Q: Are there any packaging differences between substitute parts? A: All substitute parts use Module, Wire Leads packaging with chassis mount configuration. Packaging is listed as Bulk for all active substitutes, while the obsolete OPB992P55Z has no specified packaging designation.

Q: Which substitute offers the best inventory availability? A: OPB992P51Z provides the highest inventory level at 69,800 pieces, followed by OPB992N55Z at 20,299 pieces. Both are active products within the OPB992 series.

Q: Are all substitutes RoHS and REACH compliant? A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the OPB992P55Z.
