SE1470-003 Infrared Emitter Equivalent & Substitute Parts

Part Overview

The SE1470-003 is an infrared (IR) emitter manufactured by Honeywell Sensing and Productivity Solutions, designed for applications requiring 880nm wavelength emission at 50mA maximum forward current. This component features a coaxial metal can package with a 24° viewing angle and operates across the temperature range of -55°C to 125°C.

The SE1470-003 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing system maintenance, repair, and new design implementations where this specific part number is no longer readily available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SE1470-003 is evaluated based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Infrared emitter type classification
• Wavelength range compatibility (880nm nominal)
• Forward voltage compatibility (1.8V typical)
• Viewing angle consistency (24°)
• Through-hole mounting configuration
• Operating temperature range coverage
• RoHS and environmental compliance status

The OP215A from TT Electronics/Optek Technology qualifies as a substitute based on these parameters. While the OP215A operates at 890nm wavelength (10nm longer than the SE1470-003) and supports higher maximum forward current (100mA versus 50mA), it maintains the same forward voltage (1.8V typical), identical viewing angle (24°), and through-hole mounting type. The OP215A extends the operating temperature range to -65°C to 125°C and maintains RoHS compliance. The radial package configuration of the OP215A differs from the coaxial metal can package of the SE1470-003, requiring mechanical design verification for board-level integration.

Engineering Selection Recommendations

For SE1470-003 Replacement:

The OP215A is suitable as a substitute component when the following conditions are met:

1. Mechanical Integration: The radial package configuration of the OP215A requires verification against the original coaxial metal can footprint. Board layout and mechanical mounting must be reassessed to accommodate the different package geometry.

2. Electrical Operation: The OP215A operates at identical forward voltage (1.8V typical) and supports the SE1470-003 maximum current specification (50mA) within its 100mA maximum rating. Circuit-level current limiting and voltage regulation remain compatible.

3. Wavelength Consideration: The 890nm wavelength of the OP215A represents a 10nm shift from the SE1470-003 880nm specification. System-level optical receiver sensitivity and filter characteristics must confirm acceptable performance at this wavelength variance.

4. Compliance Status: The OP215A maintains RoHS3 compliance and is actively manufactured, ensuring long-term availability and supply chain stability compared to the obsolete SE1470-003.

5. Temperature Range: The OP215A extends the lower operating temperature limit to -65°C, providing enhanced performance margin for applications requiring operation below -55°C.

Frequently Asked Questions (FAQ)

Q: Can the OP215A directly replace the SE1470-003 without circuit modification?

A: Electrical substitution is feasible without circuit modification due to identical forward voltage (1.8V) and compatible current ratings. However, mechanical substitution requires board layout redesign because the OP215A uses a radial package while the SE1470-003 uses a coaxial metal can package. Mounting holes, component spacing, and thermal management may require adjustment.

Q: What is the significance of the 10nm wavelength difference between 880nm and 890nm?

A: Both wavelengths fall within the near-infrared spectrum and are commonly used in IR sensing applications. The 10nm variance is within typical IR receiver filter bandwidths. System-level optical receiver specifications must be reviewed to confirm acceptable performance at 890nm. Applications with narrowband optical filtering may require validation testing.

Q: Does the OP215A's higher maximum current rating (100mA vs. 50mA) affect compatibility?

A: No. The OP215A's higher maximum current rating provides design margin. When operated at or below the SE1470-003 maximum current specification (50mA), the OP215A functions within its safe operating region. The higher rating does not introduce incompatibility; it allows for potential future design optimization.

Q: Are there compliance or certification differences between the two parts?

A: Both parts are RoHS compliant. The SE1470-003 carries RoHS Compliant status, while the OP215A carries ROHS3 Compliant status, indicating compliance with the current RoHS3 standard. Both parts are classified under ECCN EAR99 and HTSUS 8541.41.0000. No compliance barriers exist for substitution.

Q: What is the impact of the extended temperature range of the OP215A (-65°C vs. -55°C)?

A: The OP215A's extended lower temperature limit to -65°C provides additional operational margin for applications requiring operation in cold environments. This represents an enhancement over the SE1470-003 specification and does not introduce compatibility issues.

Q: How should the package change from coaxial to radial be managed in a design?

A: The radial package configuration requires mechanical redesign of the PCB footprint and component mounting. Through-hole mounting remains consistent, but hole spacing and component orientation differ. Physical samples and board layout verification are necessary before production implementation.
