Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPF345C is determined by matching the following critical parameters:

• Wavelength: 850nm
• Spectral Bandwidth: 35nm
• Voltage - Forward (Vf) (Typ): 2V
• Current - DC Forward (If) (Max): 100mA
• Voltage - DC Reverse (Vr) (Max): 1V
• Package Type: TO46
• RoHS Compliance: ROHS3 Compliant

The OPF345A qualifies as a direct substitute, meeting all specified electrical and mechanical parameters while maintaining identical optical and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The OPF345A is the qualified substitute for the obsolete OPF345C. Both components are manufactured by TT Electronics / Optek Technology and maintain identical electrical specifications, optical characteristics, and compliance certifications.

The OPF345A carries active product status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for component procurement and system integration.

Frequently Asked Questions (FAQ)

Q: Can OPF345A directly replace OPF345C in existing designs?

A: Yes. The OPF345A meets all electrical, optical, and mechanical specifications of the OPF345C. Both components operate at 850nm wavelength with identical forward voltage (2V), maximum forward current (100mA), and reverse voltage (1V) ratings. Package compatibility is maintained in the TO46 form factor.

Q: What is the primary advantage of using OPF345A over OPF345C?

A: The OPF345A maintains active product status, ensuring ongoing manufacturing availability and supply chain continuity. The OPF345C is classified as obsolete and subject to discontinuation.

Q: Are there compliance differences between these parts?

A: No. Both OPF345C and OPF345A carry identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 1 - Unlimited) is equivalent across both components.

Q: What packaging options are available for the OPF345A?

A: The OPF345A is supplied in bulk packaging. The OPF345C packaging specification was not provided in the available data.
