Substitute Part Grouping Explanation
Substitution for the OPB930W55 is determined by strict equivalence across the following parameters: sensing method (through-beam), sensing distance (0.125" / 3.18mm), output configuration (totem pole buffer), mounting type (chassis mount), electrical specifications (4.75V–5.25V supply, 15mA current, 70ns response time), operating temperature range (-40°C to 70°C), package type (module with wire leads), and moisture sensitivity level (MSL 1). All substitute parts listed maintain identical electrical and mechanical characteristics to the original part, with the primary distinction being product status and RoHS compliance. The OPB930W55Z represents the direct equivalent with updated packaging (bag vs. unspecified original packaging) and active product status. The OPB930W51Z, OPB940 series (OPB940W51Z, OPB940W55Z), and OPB980 series (OPB980L11Z, OPB980L51Z, OPB980L55Z, OPB980P11Z, OPB980P51Z, OPB980P55Z) all share identical functional and electrical parameters, differing only in base product designation and packaging format (bulk).

Q: What is the difference between OPB930W51Z and OPB930W55Z? A: Both parts share identical electrical and mechanical specifications. The difference is packaging format: OPB930W51Z uses bulk packaging while OPB930W55Z uses bag packaging. Inventory availability also differs (2332 pcs vs. 1313 pcs respectively).
Q: Are OPB940 and OPB980 series parts compatible with OPB930W55 applications? A: Yes. OPB940W51Z, OPB940W55Z, OPB980L11Z, OPB980L51Z, OPB980L55Z, OPB980P11Z, OPB980P51Z, and OPB980P55Z all maintain identical sensing distance, output configuration, electrical specifications, response time, and operating temperature range. All are functionally equivalent for through-beam optical sensing applications requiring 0.125" (3.18mm) sensing distance.
Q: Does packaging format affect electrical performance? A: No. Packaging format (bag, bulk, or unspecified) does not affect electrical or mechanical performance. Selection should be based on procurement requirements and inventory availability.
Q: Are all substitute parts ROHS3 compliant? A: All listed substitute parts carry ROHS3 compliance status. The original OPB930W55 is RoHS non-compliant. This compliance upgrade is a key advantage of substitution for new designs and regulated applications.
