SE5455-003 Infrared Emitter 935nm Equivalent & Substitute Parts

Part Overview

The SE5455-003 is an infrared (IR) emitter operating at 935nm wavelength, manufactured by Honeywell Sensing and Productivity Solutions. This component is rated for 100mA forward current with a typical forward voltage of 1.7V and a 20° viewing angle in a TO-46-2 metal can package. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across forward current, wavelength, and thermal operating range specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SE5455-003 are identified based on the following electrical and mechanical compatibility criteria:

Primary Matching Criteria:

• Wavelength: 935nm (exact match required for optical system function)
• Forward Current Rating: 100mA (identical maximum rating)
• Package Type: TO-46-2 Metal Can (mechanical and thermal compatibility)
• Mounting Type: Through Hole (assembly process compatibility)

Secondary Compatibility Factors:

• Forward Voltage (Vf): Tolerance range 1.7V to 1.75V (acceptable for circuit design)
• Viewing Angle: 18° to 20° (minor optical field variation acceptable within system design margins)
• Operating Temperature: Minimum -55°C to -65°C and maximum 125°C (all parts meet or exceed original specification)
• RoHS Compliance: All substitute parts meet ROHS3 or equivalent standards

The three substitute parts (OP130, OP131, OP132) manufactured by TT Electronics/Optek Technology satisfy all primary matching criteria. These parts differ in radiant intensity (Ie) specifications, which represent performance grades within the same optical and electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SE5455-003 is classified as obsolete. All three substitute parts (OP130, OP131, OP132) are active products with confirmed inventory availability, ensuring long-term procurement viability and manufacturing support.

Compliance and Certification: All substitute parts maintain ROHS3 compliance, meeting or exceeding the RoHS compliance status of the original part. All parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory equivalence.

Electrical Compatibility: Forward voltage increases from 1.7V (SE5455-003) to 1.75V (all substitutes), representing a 0.05V difference. This variation is within acceptable design margins for standard IR emitter driver circuits. Forward current rating remains constant at 100mA across all parts.

Optical and Thermal Performance: Substitute parts feature an 18° viewing angle compared to the original 20°, representing a 2° reduction in optical field. Operating temperature range is extended to -65°C minimum (versus -55°C), providing improved low-temperature performance. All parts maintain the 125°C maximum operating temperature.

Radiant Intensity Grades: The three substitute parts offer differentiated radiant intensity specifications (1mW/cm², 3mW/cm², and 4mW/cm² @ 100mA). Selection among these grades depends on system optical requirements. The original SE5455-003 does not specify radiant intensity, requiring system-level analysis to determine appropriate substitute grade.

Frequently Asked Questions (FAQ)

Q: Can OP130, OP131, and OP132 be used interchangeably with SE5455-003?

A: All three parts meet the core electrical and mechanical compatibility requirements: 935nm wavelength, 100mA forward current, TO-46-2 package, and through-hole mounting. However, they differ in radiant intensity output. Selection must be based on the optical power requirements of the specific application. If the original design does not specify radiant intensity, the lowest-grade substitute (OP130 at 1mW/cm²) provides the most conservative replacement.

Q: What is the impact of the 0.05V forward voltage increase?

A: The increase from 1.7V to 1.75V is a 2.9% change. Standard IR emitter driver circuits accommodate this variation through current-limiting resistor design. No circuit redesign is required for this voltage difference.

Q: How does the 2° viewing angle reduction affect system performance?

A: The substitute parts feature an 18° viewing angle versus the original 20°. This represents a 10% reduction in optical field width. System optical design must accommodate this narrower beam angle. Applications requiring the full 20° field may experience reduced coverage at the system edges.

Q: Are the substitute parts available in the same packaging options?

A: OP130 and OP132 are available in Bulk packaging. OP131 packaging is not specified in the provided data. All three parts are supplied in TO-46-2 Lens Top Metal Can packages, which are mechanically compatible with TO-46-2 Metal Can PCB footprints.

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 optical power budget of the application.

Q: Do the substitute parts meet the same regulatory requirements?

A: Yes. All substitute parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications as the original SE5455-003, confirming full regulatory equivalence.

Q: What is the extended operating temperature range benefit?

A: Substitute parts operate from -65°C to 125°C, compared to the original -55°C to 125°C range. This provides an additional 10°C of low-temperature performance margin, beneficial for applications in cold environments or extended thermal cycling scenarios.
