SE5455-002 Infrared Emitter 935nm Equivalent & Substitute Parts

Part Overview

The SE5455-002 is an infrared (IR) emitter manufactured by Honeywell Sensing and Productivity Solutions, operating at 935nm wavelength with a maximum forward current of 100mA. This component is housed in a TO-46-2 metal can package and is designed for through-hole mounting applications requiring near-infrared emission in the 935nm spectrum.

The SE5455-002 is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where the original part is no longer readily available from the manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SE5455-002 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Wavelength: 935nm (exact match required)
• Maximum Forward Current: 100mA (exact match required)
• Package Type: TO-46-2 Metal Can (exact match required)
• Mounting Type: Through Hole (exact match required)

Secondary Compatibility Criteria:

• Forward Voltage (Vf): Tolerance within typical operating range
• Viewing Angle: Acceptable variance within application requirements
• Operating Temperature Range: Must encompass or exceed the original specification
• RoHS Compliance: Preferred for regulatory alignment

The substitute parts OP130, OP131, and OP132 (all manufactured by TT Electronics/Optek Technology) meet all primary compatibility criteria. These parts share the identical wavelength (935nm), maximum forward current (100mA), and package configuration (TO-46-2 Metal Can). All substitute parts are classified as active products with current manufacturing status, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute Recommendation: OP132

The OP132 is the preferred substitute for the SE5455-002. This part maintains full electrical and mechanical compatibility while offering enhanced specifications. The OP132 is classified as an active product with current manufacturing status, ensuring reliable long-term availability. ROHS3 compliance exceeds the original RoHS requirement, supporting modern regulatory standards. The higher radiant intensity specification (4mW/cm² @ 100mA) provides improved optical performance compared to the original part.

Secondary Substitute Options: OP131 and OP130

The OP131 and OP130 are functionally equivalent alternatives with identical electrical parameters and package configuration. Both parts are active products with ROHS3 compliance. The OP131 provides 3mW/cm² radiant intensity, while the OP130 provides 1mW/cm² radiant intensity. Selection between these options depends on specific application requirements for optical output intensity.

Compatibility Considerations:

All substitute parts operate at 1.75V forward voltage, compared to the original 1.7V specification. This 0.05V difference is within acceptable tolerance for standard circuit designs. The substitute parts feature an 18° viewing angle compared to the original 20° specification; applications requiring the wider 20° angle must evaluate whether the 18° angle meets functional requirements. All substitute parts extend the lower operating temperature limit to -65°C, providing enhanced cold-temperature performance.

Frequently Asked Questions (FAQ)

Q: Can OP130, OP131, and OP132 be used interchangeably with SE5455-002?

A: Yes, all three Optek parts are electrically and mechanically compatible with the SE5455-002. They share identical wavelength (935nm), maximum forward current (100mA), and TO-46-2 package configuration. The primary differences are radiant intensity specifications and forward voltage (1.75V vs. 1.7V), which are within acceptable operating tolerances.

Q: What is the difference between OP130, OP131, and OP132?

A: The three parts are identical except for radiant intensity specifications. OP130 provides 1mW/cm² @ 100mA, OP131 provides 3mW/cm² @ 100mA, and OP132 provides 4mW/cm² @ 100mA. Selection depends on the required optical output intensity for the application.

Q: Does the 18° viewing angle of the substitute parts affect compatibility with the original 20° specification?

A: The substitute parts have a narrower viewing angle (18° vs. 20°). Applications requiring the full 20° angle must evaluate whether the 18° angle is acceptable for their specific optical design. In many applications, the 2° difference is negligible.

Q: Are the substitute parts RoHS compliant?

A: Yes, all substitute parts (OP130, OP131, OP132) are ROHS3 compliant, which exceeds the RoHS compliance of the original SE5455-002. This ensures compatibility with modern environmental and regulatory requirements.

Q: What is the forward voltage difference between SE5455-002 and the substitute parts?

A: The SE5455-002 operates at 1.7V typical forward voltage, while the substitute parts operate at 1.75V. This 0.05V difference is within standard tolerance for infrared emitter circuits and does not require circuit redesign in typical applications.

Q: Are the substitute parts currently available?

A: Yes, all substitute parts are classified as active products with current manufacturing status. OP130 has 1738 units in stock, OP131 has 1900 units in stock, and OP132 has 2049 units in stock, ensuring reliable availability for production requirements.

Q: What is the operating temperature range of the substitute parts?

A: The substitute parts operate from -65°C to 125°C, which extends the lower temperature limit compared to the original SE5455-002 (-55°C to 125°C). This provides enhanced performance in cold-temperature environments.
