SE5470-002 Infrared Emitter 880nm Equivalent & Substitute Parts

Part Overview

The SE5470-002 is an infrared (IR) emitter manufactured by Honeywell Sensing and Productivity Solutions, designed for 880nm wavelength applications requiring 100mA forward current operation. This component operates at a typical forward voltage of 1.9V with a radiant intensity of 1.5mW/cm² at maximum current and a 20° viewing angle in a TO-46-2 metal can package.

The SE5470-002 is classified as obsolete. Locating equivalent and substitute parts is necessary to support ongoing system maintenance, repair, and new design implementations where this wavelength and performance specification are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SE5470-002 is determined by the following critical parameters:

Primary Substitution Criteria:

• Wavelength: 880nm operation (primary functional requirement)
• Current Rating: 100mA maximum forward current
• Package Type: TO-46-2 metal can form factor
• Mounting: Through-hole configuration
• Operating Temperature Range: Compatibility with -55°C to 125°C or broader range

Secondary Compatibility Factors:

• Forward Voltage (Vf): Typical values between 1.5V and 2V are acceptable within standard circuit design tolerances
• Radiant Intensity: Minimum 1mW/cm² at 100mA maintains functional performance
• Viewing Angle: 18° to 20° range supports equivalent optical characteristics
• RoHS and MSL Compliance: Active product status with current certifications ensures supply chain availability

Parts meeting these criteria are classified as direct substitutes. Parts with wavelengths outside the 880nm specification (such as 890nm, 935nm) are classified as near-equivalent alternatives suitable for applications where wavelength tolerance permits.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute (Preferred):

PDI-E804 (Advanced Photonix) is the primary direct substitute for SE5470-002. Both components operate at 880nm wavelength with 100mA maximum forward current in identical TO-46-2 metal can packages. PDI-E804 carries active product status with ROHS3 compliance, ensuring long-term supply chain availability. The forward voltage of 1.5V is lower than the SE5470-002 typical value of 1.9V, which is acceptable within standard circuit design margins. The operating temperature range of -40°C to 100°C is narrower than the original specification; applications requiring full -55°C to 125°C operation must evaluate this limitation against specific system requirements.

Near-Equivalent Alternatives:

OP231 and OP233 (TT Electronics/Optek Technology) operate at 890nm wavelength, a 10nm offset from the 880nm specification. Both components maintain 100mA current rating and TO-46-2 package compatibility with active product status and ROHS3 compliance. The 2V typical forward voltage and 18° viewing angle differ slightly from the original specification. These parts are suitable for applications where 890nm wavelength operation is acceptable within system design tolerances.

OP130 (TT Electronics/Optek Technology) operates at 935nm wavelength with 100mA current rating and active product status. This part represents a significant wavelength departure (55nm offset) and is suitable only for applications where longer wavelength operation is compatible with system requirements.

All substitute parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating and EAR99 export classification consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can PDI-E804 directly replace SE5470-002 in existing designs?

A: PDI-E804 is a direct substitute for wavelength and current specifications. The forward voltage difference (1.5V vs. 1.9V) requires circuit verification to confirm adequate LED drive current under actual operating conditions. The narrower operating temperature range (-40°C to 100°C vs. -55°C to 125°C) must be evaluated against application temperature requirements.

Q: What is the difference between the 880nm and 890nm emitters?

A: The 10nm wavelength difference between SE5470-002/PDI-E804 (880nm) and OP231/OP233 (890nm) affects optical system performance. Applications using wavelength-specific detectors or filters must confirm compatibility. The 890nm parts are suitable only where system design permits this wavelength tolerance.

Q: Why do OP231 and OP233 have identical specifications?

A: OP231 and OP233 are both 890nm infrared emitters with identical electrical and optical parameters. Both are manufactured by TT Electronics/Optek Technology in TO-46-2 Lens Top Metal Can packages with active product status. Selection between these parts depends on inventory availability and packaging requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. SE5470-002 is RoHS Compliant. All substitute parts (PDI-E804, OP231, OP233, OP130) carry ROHS3 Compliant status, confirming compliance with current RoHS directives.

Q: What is the significance of the TO-46-2 package designation?

A: TO-46-2 is a through-hole metal can package for infrared emitters. SE5470-002 uses a standard TO-46-2 Metal Can. Substitute parts OP231, OP233, and OP130 use TO-46-2 Lens Top Metal Can variants, which include integrated optical lenses. PDI-E804 uses standard TO-46-2 Metal Can, matching the original package type. Lens-equipped variants may affect optical beam characteristics and should be evaluated for specific application requirements.

Q: Can OP130 (935nm) be used in place of SE5470-002 (880nm)?

A: OP130 operates at 935nm, a 55nm wavelength offset from the original 880nm specification. This part is suitable only for applications where the longer wavelength is compatible with system detectors, filters, and optical design. Direct substitution without system-level evaluation is not recommended.

Q: What inventory status should influence part selection?

A: PDI-E804 has 744 units in stock, OP231 has 4,118 units, and OP233 has 30,149 units available. OP130 has 1,738 units in stock. All substitute parts carry active product status, ensuring continued availability. Selection should prioritize parts with adequate inventory for project timelines and volume requirements.
