Substitute Part Grouping Explanation

The OPF370A qualifies as a direct substitute for the OPF390A based on electrical and optical parameter equivalence. Substitution is valid when the following criteria are met:

• Wavelength: 850nm (identical)
• Spectral Bandwidth: 35nm (identical)
• Voltage - Forward (Vf) (Typ): 2V (identical)
• Current - DC Forward (If) (Max): 100mA (identical)
• Voltage - DC Reverse (Vr) (Max): 1V (identical)
• RoHS Status: ROHS3 Compliant (equivalent compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (equivalent handling)
• REACH Status: REACH Unaffected (equivalent regulatory status)

The OPF370A is manufactured by the same supplier (TT Electronics / Optek Technology) and maintains active product status, ensuring continued availability and support.
