Substitute Part Grouping Explanation

The OPF370A qualifies as a direct substitute for the OPF390C based on matching electrical and optical parameters. 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 (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)

The OPF370A maintains full electrical and optical compatibility with the OPF390C while offering the advantage of active product status and higher current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The OPF370A is the qualified substitute for OPF390C applications. Selection of OPF370A is supported by:

• Identical electrical specifications across all critical parameters (forward voltage, forward current, reverse voltage)
• Identical optical specifications (wavelength and spectral bandwidth)
• Active product status ensuring long-term availability and supply chain continuity
• Equivalent regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification)
• Identical moisture sensitivity rating and handling requirements
• Higher inventory availability (1273 units vs. 984 units for OPF390C)

Frequently Asked Questions (FAQ)

Q: Can OPF370A directly replace OPF390C in existing designs?

A: Yes. The OPF370A meets all electrical and optical parameter requirements of the OPF390C, including wavelength (850nm), forward voltage (2V), forward current (100mA), and reverse voltage (1V) specifications.

Q: What is the primary advantage of using OPF370A over OPF390C?
