OPF320C Equivalent & Substitute Parts

Part Overview

The OPF320C is a fiber optic transmitter operating at 850nm wavelength, manufactured by TT Electronics/Optek Technology in a TO46 package. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement.

The OPF320C is designed for applications requiring 850nm fiber optic transmission with a forward voltage of 2V and maximum forward current of 100mA. Due to its obsolete status, sourcing direct replacements from active product lines is necessary for system maintenance and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPF320C is based on electrical and mechanical parameter equivalence within the 850nm fiber optic transmitter category. The following parameters determine substitutability:

• Wavelength: 850nm (exact match required)
• Spectral Bandwidth: 35nm (exact match required)
• Voltage - Forward (Vf) (Typ): 2V (exact match required)
• Current - DC Forward (If) (Max): 100mA (exact match required)
• Voltage - DC Reverse (Vr) (Max): 1V (exact match required)
• Package: TO46 (exact match required)

The OPF320B meets all specified electrical and mechanical parameters and is classified as an active product from the same manufacturer, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The OPF320B is the recommended substitute for the OPF320C. Both components are manufactured by TT Electronics/Optek Technology and share identical electrical specifications and package configuration. The OPF320B maintains active product status, ensuring continued availability and supply chain reliability.

Both parts comply with ROHS3 requirements and are REACH unaffected, meeting current environmental and regulatory standards. The MSL rating of 1 (Unlimited) applies to both components, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the OPF320B directly replace the OPF320C in existing designs?

A: Yes. The OPF320B is electrically and mechanically equivalent to the OPF320C. All critical parameters including wavelength, forward voltage, forward current, reverse voltage, and package type are identical.

Q: Why is the OPF320C listed as obsolete?

A: The OPF320C has been discontinued by the manufacturer. The OPF320B represents the active product line continuation from TT Electronics/Optek Technology for this 850nm fiber optic transmitter specification.

Q: Are there any compliance differences between these parts?

A: No. Both the OPF320C and OPF320B carry identical ROHS3 compliance status and REACH unaffected designation. Moisture sensitivity levels are also equivalent at MSL 1 (Unlimited).

Q: What is the base product number for these components?

A: The base product number is OPF320. Both the OPF320C and OPF320B are variants within this product family.

Q: Are there packaging differences between the OPF320C and OPF320B?

A: Both components use TO46 packaging. The OPF320B is available in bulk packaging format.
