These parts maintain all critical electrical parameters and operating characteristics while offering varying packaging and base product configurations. Selection among parametric equivalents should be based on specific packaging requirements and inventory availability for the application.

Frequently Asked Questions (FAQ)

Q: Can OPB880T11Z directly replace OPB880L11Z? A: Yes. OPB880T11Z is the manufacturer-recommended substitute with identical electrical specifications, sensing distance, output configuration, and operating temperature range. The primary difference is product status (Active vs. Obsolete) and packaging format.

Q: What determines compatibility between OPB880L11Z and the parametric equivalent parts? A: Compatibility is determined by matching sensing distance (0.125"), sensing method (Through-Beam), output configuration (Phototransistor), current ratings (If 50 mA max, Ic 30 mA max), voltage breakdown (30 V), operating temperature range (-40°C ~ 85°C), mounting type (Chassis Mount), and package type (Module, Pre-Wired). All listed substitutes meet these criteria.

Q: Are there packaging differences between substitute parts? A: Packaging variations exist in the suffix designations (N11, N51, P55, P51Z, T11Z, L11Z) which indicate different connector or lead configurations. All parts maintain the same Module, Pre-Wired package classification and chassis mount configuration. Specific packaging selection depends on application connector requirements.

Q: Do all substitute parts have the same compliance certifications? A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry identical environmental and regulatory certifications as the OPB880L11Z.

Q: Which substitute has the highest inventory availability? A: OPB370N55 has the highest inventory with 90,400 pieces in stock, followed by OPB365N51 with 1,916 pieces. Both are active products suitable for immediate procurement.
