Engineering Selection Recommendations

The OPB810W51 is classified as obsolete. For new designs or component replenishment, selection from the active product line is recommended to ensure long-term supply chain continuity. All listed substitute parts maintain identical electrical and mechanical specifications, ensuring functional equivalence in applications currently using the OPB810W51.

OPB810W51Z represents the direct successor with identical base product designation and active product status. OPB800W51Z offers the highest inventory availability at 12796 units, providing supply security for high-volume applications. All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can OPB810W51Z be used as a direct replacement for OPB810W51?

A: Yes. OPB810W51Z maintains identical electrical and mechanical parameters. The primary difference is product status (active versus obsolete) and packaging designation (bulk). Functional performance in circuit applications remains equivalent.

Q: What is the difference between OPB810W51Z and OPB800W51Z?

A: Both parts share identical electrical specifications and sensing characteristics. The difference lies in the base product designation (OPB810 versus OPB800). OPB800W51Z offers significantly higher inventory availability (12796 units versus 1570 units).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What does the "W51" and "W55" designation indicate?

A: These designations are part of the manufacturer's part numbering scheme. Both W51 and W55 variants maintain identical electrical and mechanical parameters specified for this optical sensor category. Selection between variants should be based on specific application requirements and inventory availability.

Q: Is packaging configuration a factor in substitution?

A: The OPB810W51 uses module pre-wired packaging with chassis mount configuration. All substitute parts maintain this identical packaging and mounting specification. Bulk packaging designation on substitute parts refers to order quantity packaging, not component packaging configuration.
