Frequently Asked Questions (FAQ)

Q: Can OPB867T55 replace OPB867P55 in existing designs?

A: OPB867T55 maintains identical electrical parameters and sensing characteristics. The primary difference is mounting type: OPB867T55 uses Through Hole PCB Mount while OPB867P55 uses Chassis Mount. Substitution is feasible only if the design can accommodate PCB mount integration instead of chassis mounting.

Q: What distinguishes the parametric equivalent parts from OPB867T55?

They differ in base product number designation and specific packaging variants but preserve all functional parameters required for through-beam phototransistor operation.

Q: Are all substitute parts currently in active production?

A: Yes. All listed substitute parts carry Active product status, ensuring ongoing availability and manufacturing support. The original OPB867P55 is obsolete, making these active alternatives necessary for new procurement and design continuity.

Q: Do substitute parts meet the same compliance requirements?

A: All substitute parts are ROHS3 compliant and REACH Unaffected, matching the regulatory status of OPB867P55. Moisture Sensitivity Level remains 1 (Unlimited) across all alternatives.

Q: What is the inventory status of substitute parts?

A: OPB370N55 maintains the highest inventory at 90,400 pieces. Other parametric equivalents range from 648 to 1,916 pieces. OPB867T55 (MFR recommended) has 1,420 pieces available. Inventory levels support both immediate procurement and long-term supply planning.

Q: Can multiple substitute parts be used interchangeably in the same application?

A: All listed parts share identical electrical parameters, sensing distance, and environmental ratings. Interchangeability depends on mechanical mounting compatibility. Chassis mount variants (OPB360N51, OPB365N11, OPB365N51, OPB365P55, OPB370N51, OPB370N55, OPB375N51, OPB380N11Z, OPB380P51Z) are directly interchangeable with OPB867P55.
