Key Parameters

Substitute Part Grouping Explanation

Substitution between OPF322C and OPF322A is based on matching the following critical parameters:

• Wavelength: 850nm (identical)
• Spectral Bandwidth: 35nm (identical)
• Forward Voltage (Vf): 2V (identical)
• Maximum Forward Current (If): 100 mA (identical)
• Reverse Voltage (Vr): 1V (identical)
• Connector Type: ST (identical)
• Package: TO46 (identical)
• RoHS Compliance: ROHS3 Compliant (identical)
• Moisture Sensitivity: MSL 1 (identical)

Both parts share the same base product number (OPF322) and are manufactured by TT Electronics/Optek Technology. The OPF322A maintains full electrical, optical, and mechanical compatibility with the OPF322C.

Parameter Comparison

Engineering Selection Recommendations

The OPF322A is the manufacturer-recommended substitute for the obsolete OPF322C. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The OPF322A maintains active product status, ensuring continued availability and supply chain support.

Selection of OPF322A over OPF322C is driven by product lifecycle considerations. The OPF322A provides identical electrical performance, optical characteristics, and mechanical compatibility while offering the advantage of active manufacturing status.

Frequently Asked Questions (FAQ)
