SE2460-003 Infrared Emitter 935nm Equivalent & Substitute Parts

Part Overview

The SE2460-003 is an infrared (IR) emitter manufactured by Honeywell Sensing and Productivity Solutions, designed for applications requiring 935nm wavelength emission at 75mA forward current. This component operates at a typical forward voltage of 1.6V with an 18° viewing angle in a Mini-pill surface mount package.

The SE2460-003 is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing production support, design updates, or inventory replenishment where original stock is unavailable or depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SE2460-003 is determined by the following critical parameters:

Primary Matching Criteria:

• Wavelength: 935nm (exact match required for optical system compatibility)
• Package / Case: Mini-pill (mechanical and thermal compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)

Secondary Compatibility Parameters:

• Current - DC Forward (If) (Max): Substitute must support the application's required current level
• Voltage - Forward (Vf) (Typ): Forward voltage must be compatible with circuit design
• Viewing Angle: Optical beam characteristics for system performance
• Operating Temperature Range: Must encompass application environment
• RoHS and MSL Compliance: Regulatory and manufacturing process requirements

The OP124 from TT Electronics/Optek Technology meets the primary matching criteria and is classified as an equivalent substitute based on identical wavelength, package type, and mounting configuration.

Engineering Selection Recommendations

SE2460-003 (Honeywell) - Primary Part:

• Product Status: Obsolete
• RoHS Compliance: RoHS Compliant
• Availability: 1026 Pcs in stock

OP124 (TT Electronics/Optek) - Substitute Part:

• Product Status: Active
• RoHS Compliance: ROHS3 Compliant
• Availability: 3211 Pcs in stock
• Operating Temperature Range: Extended to -65°C (5°C lower minimum than SE2460-003)

The OP124 is suitable as a substitute for the SE2460-003 in applications where the following conditions are met:

1. The circuit design accommodates the lower typical forward voltage (1.5V vs. 1.6V)
2. The application can operate with the higher maximum forward current rating (100mA vs. 75mA)
3. The wider viewing angle (24° vs. 18°) is acceptable for the optical system design
4. The extended lower operating temperature (-65°C vs. -55°C) provides additional environmental margin

The OP124 offers active product status and higher inventory availability, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the OP124 directly replace the SE2460-003 in existing designs?

A: The OP124 is mechanically and optically compatible as both components share identical wavelength (935nm), Mini-pill package, and surface mount configuration. However, circuit-level compatibility must be verified. The OP124 has a lower typical forward voltage (1.5V vs. 1.6V) and higher maximum current rating (100mA vs. 75mA). Designs operating the SE2460-003 at its maximum 75mA rating will operate the OP124 within its rated specifications.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Forward voltage: OP124 is 0.1V lower; (2) Maximum forward current: OP124 is rated 25mA higher; (3) Viewing angle: OP124 is 6° wider; (4) Operating temperature minimum: OP124 extends 10°C lower; (5) Product status: OP124 is active while SE2460-003 is obsolete.

Q: Are both parts RoHS compliant?

A: Yes. The SE2460-003 is RoHS Compliant. The OP124 is ROHS3 Compliant, representing a more recent RoHS certification standard.

Q: What is the moisture sensitivity level for both parts?

A: Both the SE2460-003 and OP124 have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: The OP124 is recommended for new designs due to its active product status, higher inventory availability, extended operating temperature range, and ROHS3 compliance. The SE2460-003 should be used only when existing designs specifically require its electrical or optical characteristics.
