OP265W Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The OP265W is an infrared (IR) emitter operating at 890nm wavelength, designed for through-hole mounting in T-1 package configuration. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The OP265W specifications—890nm wavelength, 50mA forward current, 1.8V forward voltage, and 90° viewing angle—define the functional requirements for direct substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP265W is determined by strict equivalence across the following critical parameters:

• Wavelength: 890nm (exact match required)
• Forward Current Rating: 50mA maximum (exact match required)
• Forward Voltage: 1.8V typical (exact match required)
• Viewing Angle: 90° (exact match required)
• Package Type: T-1 through-hole (exact match required)
• Operating Temperature Range: -40°C ~ 100°C (exact match required)

The OP266W meets all specified parameters identically to the OP265W. The primary distinction is product status: OP265W is obsolete while OP266W is active, with equivalent inventory availability and identical electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The OP266W is the direct equivalent for OP265W applications. Both components are manufactured by TT Electronics/Optek Technology and share identical electrical specifications, mechanical configuration, and compliance certifications. The OP266W maintains active product status with established supply availability, whereas the OP265W is obsolete. For new designs and ongoing production requiring 890nm IR emitters with 50mA forward current in T-1 through-hole packages, the OP266W provides continuity of function and compliance with ROHS3, REACH, and EAR99 classifications.

Frequently Asked Questions (FAQ)

Q: Can OP266W directly replace OP265W in existing circuit designs?

A: Yes. The OP266W is electrically and mechanically identical to the OP265W across all specified parameters: 890nm wavelength, 50mA forward current, 1.8V forward voltage, 90° viewing angle, T-1 through-hole package, and -40°C to 100°C operating temperature range. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The OP265W is classified as obsolete. The OP266W is the active equivalent part from the same manufacturer with identical specifications and superior supply availability.

Q: Are there packaging differences between OP265W and OP266W?

A: Both components use T-1 through-hole package configuration. The OP266W is available in bulk packaging, while the OP265W was supplied in standard packaging. This distinction does not affect electrical or mechanical compatibility.

Q: Do compliance certifications differ between these parts?

A: No. Both the OP265W and OP266W carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 classification.

Q: What parameters must match exactly for substitution?

A: Wavelength (890nm), forward current (50mA), forward voltage (1.8V), viewing angle (90°), package type (T-1), and operating temperature range (-40°C ~ 100°C) must all match exactly for direct substitution in IR emitter applications.
