Q: What is the difference between OPB960N51, OPB960T51, and OPB960P51?
A: These part numbers differ only in packaging configuration and internal design variants, not in electrical or mechanical specifications. All three maintain identical sensing distance, output configuration, supply voltage, current draw, response time, and operating temperature range. Selection can be based on packaging availability and inventory levels.
Q: Are OPB930L51 and OPB930L55 compatible with OPB960P11 applications?
A: Yes. OPB930L51 and OPB930L55 are fully compatible substitutes. They maintain all critical electrical and mechanical parameters: 0.125" sensing distance, through-beam operation, totem pole buffer output, 4.75V ~ 5.25V supply voltage, 15 mA current, 70ns response time, and -40°C ~ 70°C operating temperature. The OPB930 base product number indicates a variant within the same Photologic® family with identical functional specifications.
Q: Why is OPB960P11 listed as obsolete?
A: OPB960P11 has been discontinued by the manufacturer. All listed substitute parts are active products with ongoing manufacturing support, making them the appropriate choice for new designs and system maintenance.
Q: Do all substitute parts have the same RoHS and REACH compliance?
A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of OPB960P11.
Q: Which substitute part offers the best inventory availability?
A: OPB960T51 provides the highest inventory level at 20,199 units, followed by OPB960N51 at 8,810 units. Both options ensure reliable supply for production requirements.
