SE2460-002 Infrared Emitter 935nm Equivalent & Substitute Parts

Part Overview

The SE2460-002 is an infrared (IR) emitter manufactured by Honeywell Sensing and Productivity Solutions, designed for 935nm wavelength applications requiring 75mA forward current at 1.6V typical forward voltage. This component features an 18° viewing angle in a surface-mount mini-pill package and operates across the temperature range of -55°C to 125°C.

The SE2460-002 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SE2460-002 is determined by the following critical parameters:

Primary Matching Criteria:

• Wavelength: 935nm (exact match required)
• Package / Case: Mini-pill (mechanical compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Type: Infrared (IR) Emitter (functional category)

Secondary Compatibility Parameters:

• Forward voltage (Vf) within acceptable operating range
• Forward current (If) rating equal to or greater than original specification
• Operating temperature range encompassing or exceeding original range
• RoHS and environmental compliance status

The substitute parts OP123 and OP124, both manufactured by TT Electronics/Optek Technology, satisfy all primary matching criteria. Both components operate at 935nm wavelength in mini-pill surface-mount packages. Both are active products with current availability and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

OP124 (TT Electronics/Optek Technology) is the primary substitute for SE2460-002 applications. This component maintains 935nm wavelength operation in an identical mini-pill surface-mount package. The OP124 provides 100mA maximum forward current, exceeding the original 75mA specification, and operates across -65°C to 125°C, extending the lower temperature limit by 10°C. The component carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. Radiant intensity is specified at 1mW/cm² @ 50mA, providing measurable optical output data. Current inventory status is 3211 units.

OP123 (TT Electronics/Optek Technology) serves as a secondary substitute option. This component shares identical wavelength, package, and mounting specifications with OP124. The OP123 provides 100mA maximum forward current and operates across -65°C to 125°C. Radiant intensity is specified at 0.4mW/cm² @ 50mA, representing lower optical output compared to OP124. Current inventory status is 794 units. OP123 is suitable for applications where the lower radiant intensity specification is acceptable.

Both substitute parts are active products with established supply chains, contrasting with the obsolete status of SE2460-002. Both carry enhanced compliance certifications (ROHS3, REACH Unaffected) relative to the original component.

Frequently Asked Questions (FAQ)

Q: Can OP124 or OP123 be used as direct replacements for SE2460-002 in existing designs?

A: Both OP124 and OP123 are mechanically and functionally compatible with SE2460-002. All three components share identical 935nm wavelength, mini-pill package geometry, and surface-mount configuration. Forward voltage differs slightly (1.5V for Optek parts versus 1.6V for Honeywell), and forward current ratings are higher for the substitute parts (100mA versus 75mA). These differences are within acceptable substitution parameters for IR emitter applications.

Q: What is the primary difference between OP124 and OP123?

A: The primary difference is radiant intensity specification. OP124 provides 1mW/cm² @ 50mA, while OP123 provides 0.4mW/cm² @ 50mA. Both components operate at identical wavelength, voltage, and current ratings. Selection between these parts depends on the optical output requirements of the specific application.

Q: Are there temperature range considerations when substituting these parts?

A: The substitute parts (OP123 and OP124) extend the lower operating temperature limit to -65°C compared to SE2460-002 at -55°C. Both maintain the upper limit of 125°C. Applications operating at temperatures below -55°C benefit from the extended range of the substitute parts. Applications within the original -55°C to 125°C range experience no temperature-related limitations.

Q: Do the substitute parts meet current compliance requirements?

A: Yes. Both OP123 and OP124 carry ROHS3 compliance and REACH Unaffected status. The original SE2460-002 carries RoHS Compliant status. The substitute parts meet current regulatory standards for electronic component manufacturing and distribution.

Q: How do the viewing angles compare?

A: SE2460-002 specifies an 18° viewing angle, while both OP123 and OP124 specify 24° viewing angles. The wider viewing angle of the substitute parts may affect optical system design if the original 18° specification was critical to application performance. Applications tolerant of wider beam angles experience no functional impact.

Q: What inventory considerations apply to these substitute parts?

A: SE2460-002 is obsolete with 1095 units currently in stock. OP124 is active with 3211 units in stock. OP123 is active with 794 units in stock. For long-term supply chain planning, the active status and higher inventory levels of the substitute parts provide greater availability assurance compared to the obsolete original component.
