OP265D Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The OP265D 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 suitable substitutes essential for ongoing production support and design continuity. The OP265D remains available in inventory (780 pcs), but its obsolete status necessitates evaluation of active alternative components to ensure long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OP265D is determined by matching the following critical parameters:

• Wavelength: 890nm (infrared spectrum requirement)
• Current Rating: 50mA maximum DC forward current
• Forward Voltage: 1.8V typical operating voltage
• Viewing Angle: 18° beam angle
• Package Type: T-1 through-hole form factor
• Operating Temperature Range: -40°C to 100°C minimum
• Compliance: ROHS3 and REACH status alignment

The OP265B meets all specified electrical and mechanical parameters, maintaining identical wavelength, current, voltage, viewing angle, and thermal operating range. Both components share T-1 through-hole packaging and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The OP265B is a direct functional equivalent to the OP265D, with all electrical specifications, thermal operating range, and mechanical form factor matching identically. The primary distinction is product status: OP265D is obsolete while OP265B maintains active production status.

Selection of OP265B over OP265D is supported by:

• Identical compliance certifications (ROHS3, REACH Unaffected)
• Active product status ensuring continued availability and supply chain support
• Significantly higher inventory availability (3005 pcs vs. 780 pcs)
• No electrical or mechanical parameter deviations

For applications currently using OP265D, direct substitution with OP265B requires no circuit modifications or design changes.

Frequently Asked Questions (FAQ)

Q: Can OP265B be used as a direct replacement for OP265D in existing designs?

A: Yes. All electrical parameters (wavelength, forward current, forward voltage, viewing angle) and mechanical specifications (T-1 through-hole package, operating temperature range) are identical. No circuit modifications are required.

Q: What is the primary reason to transition from OP265D to OP265B?

A: OP265D is classified as obsolete, while OP265B maintains active production status. This ensures long-term supply chain availability and manufacturing continuity.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

Q: Does the T-1 package remain the same for both parts?

A: Yes. Both OP265D and OP265B use identical T-1 through-hole packaging, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: What is the inventory status for each part?

A: OP265D has 780 pcs available. OP265B has 3005 pcs available, providing greater supply security for new orders and production planning.
