SE5450-012 Infrared Emitter 935nm Equivalent & Substitute Parts

Part Overview

The SE5450-012 is an infrared (IR) emitter operating at 935nm wavelength, manufactured by Honeywell Sensing and Productivity Solutions. This component is rated for 100mA DC forward current with a typical forward voltage of 1.7V and radiant intensity of 0.50mW/cm² at maximum current. The device is packaged in a TO-46-2 metal can with through-hole mounting and a 20° viewing angle.

The SE5450-012 is classified as obsolete. Substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements. Three active equivalent models from TT Electronics/Optek Technology are available as direct substitutes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SE5450-012 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Wavelength: 935nm
• Maximum DC Forward Current (If): 100mA
• Package / Case: TO-46-2 Metal Can
• Mounting Type: Through Hole
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Parameter Variations:

• Forward Voltage (Vf): Substitute parts rated at 1.75V are compatible with circuits designed for 1.7V nominal operation
• Radiant Intensity (Ie): Substitute parts with higher radiant intensity (1mW/cm², 3mW/cm², 4mW/cm²) are functionally compatible; circuits designed for 0.50mW/cm² will operate with increased optical output
• Viewing Angle: Substitute parts with 18° viewing angle are compatible with applications requiring 20° or narrower beam patterns
• Operating Temperature Range: Substitute parts with extended lower temperature limit (-65°C vs -55°C) provide enhanced cold-weather performance

All three substitute parts (OP130, OP131, OP132) meet these substitution criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SE5450-012 is obsolete and no longer manufactured. All three substitute parts (OP130, OP131, OP132) are active products with confirmed current inventory availability, ensuring long-term supply chain reliability.

Compliance and Certification: All substitute parts meet ROHS3 compliance, which exceeds the RoHS Compliant status of the original part. The OP130, OP131, and OP132 are REACH Unaffected, providing additional regulatory assurance for European market applications.

Selection by Application Requirements:

• OP130: Suitable for applications requiring moderate radiant intensity (1mW/cm²) with extended cold-temperature operation (-65°C lower limit). Recommended for general-purpose infrared sensing applications.

• OP131: Suitable for applications requiring higher radiant intensity (3mW/cm²) with extended cold-temperature operation. Recommended for long-distance infrared transmission or low-sensitivity detector circuits.

• OP132: Suitable for applications requiring maximum radiant intensity (4mW/cm²) with extended cold-temperature operation. Recommended for high-performance infrared sensing systems or applications with optical attenuation requirements.

All three substitutes are electrically and mechanically compatible with circuits designed for the SE5450-012, with the primary design consideration being the increased radiant intensity output relative to the original 0.50mW/cm² specification.

Frequently Asked Questions (FAQ)

Q: Can OP130, OP131, or OP132 be used as direct replacements for SE5450-012 in existing circuit designs?

A: Yes. All three parts share identical wavelength (935nm), maximum forward current (100mA), package type (TO-46-2 Metal Can), and mounting configuration (through-hole). The forward voltage difference (1.75V vs 1.7V) is within typical circuit tolerance margins. Circuits will operate with increased radiant intensity output.

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

A: The three parts are differentiated by radiant intensity specification: OP130 provides 1mW/cm², OP131 provides 3mW/cm², and OP132 provides 4mW/cm² at 100mA forward current. All other electrical and mechanical parameters are identical.

Q: Does the 18° viewing angle of substitute parts affect compatibility with SE5450-012 applications?

A: The substitute parts have a narrower viewing angle (18°) compared to the original part (20°). This results in a more focused beam pattern. Applications designed for 20° beam width will operate with the 18° substitute parts; however, the optical coverage area will be slightly reduced.

Q: Are the substitute parts available in the same packaging as the SE5450-012?

A: The substitute parts use TO-46-2 Lens Top Metal Can packaging, which is mechanically compatible with TO-46-2 Metal Can footprints. The lens top design on substitute parts may provide improved optical performance in some applications.

Q: What is the temperature operating range difference between SE5450-012 and the substitute parts?

A: The SE5450-012 operates from -55°C to 125°C. All three substitute parts extend the lower temperature limit to -65°C, providing 10°C additional cold-weather performance margin. The upper temperature limit remains 125°C for all parts.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three substitute parts (OP130, OP131, OP132) are ROHS3 Compliant, which exceeds the RoHS Compliant status of the original SE5450-012. They are also REACH Unaffected.
