OP265FAC Equivalent & Substitute Parts

Part Overview

The OP265FAC is an infrared (IR) emitter operating at 850nm wavelength, designed for through-hole radial mounting applications. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance requirements. The OP265FAC delivers 11.5mW/cm² radiant intensity at 20mA forward current with an 18° viewing angle, operating across the industrial temperature range of -40°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OP265FAC is determined by the following critical parameters:

• Wavelength: 850nm (exact match required)
• Current - DC Forward (If) (Max): 50mA (exact match required)
• Voltage - Forward (Vf) (Typ): 1.8V (exact match required)
• Viewing Angle: 18° (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Operating Temperature Range: -40°C ~ 100°C (exact match required)

The OP265FAB qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While the radiant intensity specification differs (7.5mW/cm² @ 20mA versus 11.5mW/cm² @ 20mA), both components share identical forward current, voltage, wavelength, viewing angle, mounting configuration, and temperature operating range. The OP265FAB is currently in active production status, providing supply continuity for the obsolete OP265FAC.

Parameter Comparison

Engineering Selection Recommendations

The OP265FAB is the manufacturer-recommended substitute for the obsolete OP265FAC. Both components maintain identical electrical specifications for forward current (50mA maximum), forward voltage (1.8V typical), wavelength (850nm), viewing angle (18°), and operating temperature range (-40°C to 100°C). Both components are ROHS3 compliant and carry MSL rating of 1 (unlimited moisture sensitivity).

The OP265FAB is currently in active production status, ensuring supply availability and long-term component sourcing stability. The radiant intensity difference between the two parts does not affect substitution eligibility, as this parameter represents a performance characteristic rather than a compatibility constraint for through-hole radial mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the OP265FAB directly replace the OP265FAC in existing designs?

A: Yes. The OP265FAB matches all critical electrical and mechanical parameters of the OP265FAC, including wavelength (850nm), maximum forward current (50mA), forward voltage (1.8V), viewing angle (18°), mounting type (through hole), package configuration (radial), and operating temperature range (-40°C to 100°C).

Q: What is the difference in radiant intensity between these parts?

A: The OP265FAC specifies 11.5mW/cm² @ 20mA, while the OP265FAB specifies 7.5mW/cm² @ 20mA. This difference represents a performance variation within the same component family and does not prevent direct substitution for applications requiring 850nm infrared emission at the specified current and voltage levels.

Q: Why is the OP265FAC listed as obsolete?

A: The OP265FAC has been discontinued by the manufacturer. The OP265FAB serves as the active production alternative, providing equivalent functionality for new designs and replacement applications.

Q: Are there any packaging differences between these parts?

A: Both components use radial through-hole packaging. The OP265FAC was supplied in standard packaging, while the OP265FAB is available in bulk packaging. The physical form factor and mounting configuration remain identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the OP265FAC and OP265FAB are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited). Both are classified under ECCN EAR99 and HTSUS code 8541.41.0000.
