OP265C Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The OP265C is an infrared (IR) emitter operating at 890nm wavelength, designed for through-hole mounting applications requiring 50mA forward current at 1.8V typical forward voltage. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing production and maintenance applications. The OP265B serves as the direct substitute, offering identical electrical and mechanical specifications while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP265C with the OP265B is based on strict equivalence across all critical electrical and mechanical parameters. The substitute relationship is determined by matching the following specifications:

• Wavelength: 890nm (identical)
• Maximum forward current: 50mA (identical)
• Typical forward voltage: 1.8V (identical)
• Viewing angle: 18° (identical)
• Package type: T-1 through-hole (identical)
• Operating temperature range: -40°C ~ 100°C (identical)
• RoHS and REACH compliance status (identical)

The OP265B maintains full compatibility with circuit designs and PCB layouts originally specified for the OP265C.

Parameter Comparison

Engineering Selection Recommendations

The OP265B is the appropriate substitute for the OP265C in all applications. Both components are manufactured by TT Electronics/Optek Technology and maintain identical electrical characteristics and physical form factors. The OP265B holds active product status, ensuring continued availability and supply chain reliability compared to the obsolete OP265C. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. Selection of the OP265B eliminates obsolescence risk while preserving full functional and mechanical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the OP265B directly replace the OP265C in existing designs? A: Yes. The OP265B is electrically and mechanically identical to the OP265C across all specified parameters, including wavelength, forward current, forward voltage, viewing angle, and T-1 package configuration. No circuit modifications are required.

Q: What is the primary reason to substitute the OP265C? A: The OP265C is classified as obsolete. The OP265B provides the same functionality with active product status, ensuring long-term availability and supply chain continuity.

Q: Are there any compliance differences between the OP265C and OP265B? A: No. Both components maintain identical ROHS3 compliance and REACH unaffected status.

Q: Does the packaging differ between these parts? A: The OP265C is supplied in standard packaging, while the OP265B is supplied in bulk packaging. Both use the T-1 through-hole case. Bulk packaging does not affect component performance or compatibility.

Q: What is the operating temperature range for both parts? A: Both the OP265C and OP265B operate across -40°C to 100°C ambient temperature range.
