Frequently Asked Questions (FAQ)

Q: Can OPB890P11Z directly replace OPB890P11 without circuit modification?

A: Yes. OPB890P11Z is the direct manufacturer equivalent with identical electrical ratings (50 mA forward current, 30 mA collector current, 30 V breakdown voltage), operating temperature range (-40°C ~ 85°C), sensing distance (0.125"), and mechanical mounting. The only difference is active product status and ROHS3 compliance.

Q: What is the difference between direct equivalents and parametric equivalents?

A: OPB890P11Z is a direct equivalent sharing the same base product number (OPB890). Parametric equivalents (OPB360N51, OPB365 series, OPB370 series, OPB375N51, OPB380 series) are alternative models from the same manufacturer with identical electrical and mechanical specifications but different base product designations. All are functionally interchangeable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status. The original OPB890P11 is RoHS non-compliant. Substitution with any listed part upgrades compliance to current standards.

Q: Does packaging differ between substitute parts?

A: All substitute parts use identical packaging: Module, Pre-Wired with Chassis Mount configuration. Bulk packaging is specified for all substitutes, consistent with the original component's pre-wired module format.

Q: Which substitute part offers the best supply availability?

A: OPB370N55 maintains the highest inventory level at 90,400 units, followed by OPB365N51 at 1,916 units. Both are active products suitable for immediate procurement.

Q: Are there any electrical performance differences between substitute parts?

A: No. All substitute parts maintain identical maximum ratings: 50 mA DC forward current, 30 mA collector current, 30 V collector-emitter breakdown voltage, and -40°C to 85°C operating temperature range.
