SE1470-003L Infrared Emitter Equivalent & Substitute Parts

Part Overview

The SE1470-003L 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 SE1470-003L 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 SE1470-003L with alternative IR emitters is determined by the following critical parameters:

Wavelength Compatibility: The 880nm wavelength is the primary functional requirement. Substitute parts must operate within a narrow wavelength band to ensure compatibility with receiver circuits and optical system design.

Electrical Characteristics: Forward voltage (Vf) and maximum forward current (If) must be compatible with existing drive circuitry. The SE1470-003L operates at 1.8V typical with a 50mA maximum rating.

Optical Output: Radiant intensity specifications define the light output power density. Substitute parts must deliver equivalent or superior optical performance at comparable current levels.

Viewing Angle: The 24° viewing angle is a mechanical and optical parameter that affects system field of view and must be maintained in substitutes.

Package and Mounting: The coaxial metal can package with through-hole mounting is a physical constraint. Substitute parts must accommodate the same or compatible mounting footprint.

Environmental Compliance: RoHS compliance and operating temperature range ensure regulatory and thermal compatibility.

Engineering Selection Recommendations

OP216A as Primary Substitute:

The OP216A from TT Electronics/Optek Technology is classified as an active product with current manufacturing support and availability. This component shares the same forward voltage (1.8V typical) and viewing angle (24°) as the SE1470-003L.

The OP216A operates at a maximum forward current of 100mA, which exceeds the SE1470-003L specification of 50mA. This higher current rating provides design flexibility and does not create incompatibility when operated at or below the original 50mA specification level.

The wavelength difference between 880nm (SE1470-003L) and 890nm (OP216A) represents a 10nm shift within the near-infrared spectrum. Both wavelengths fall within the standard IR emitter band used in industrial sensing and communication applications.

The radiant intensity of the OP216A (1.2mW/cm² @ 50mA) exceeds the SE1470-003L specification (1.1mW/cm² @ 20mA), indicating superior optical output performance.

The OP216A features a radial package configuration, whereas the SE1470-003L uses a coaxial metal can package. Both are through-hole mounted components; however, the different package geometries require PCB layout modification.

The OP216A holds ROHS3 compliance status and is unaffected by REACH regulations, meeting current environmental and regulatory requirements. The operating temperature range of -65°C to 125°C exceeds the SE1470-003L range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the OP216A directly replace the SE1470-003L without circuit modification?

A: Electrical compatibility is established through matching forward voltage (1.8V) and operation within the current specification. However, the package geometry differs (radial versus coaxial metal can), requiring PCB layout changes. The 10nm wavelength difference (880nm to 890nm) is within acceptable tolerance for most IR sensing applications but must be verified against specific receiver filter specifications.

Q: What is the significance of the 100mA maximum current rating on the OP216A compared to the 50mA rating on the SE1470-003L?

A: The higher current rating on the OP216A indicates greater current handling capability. When operated at or below 50mA, the OP216A functions within its safe operating region. The higher rating does not create incompatibility; it provides additional design margin and flexibility for future applications.

Q: How does the wavelength difference between 880nm and 890nm affect system performance?

A: The 10nm wavelength shift is a minor variation within the near-infrared spectrum. Compatibility depends on the receiver photodiode or sensor filter specifications. If the original system uses a narrowband filter centered on 880nm, the 890nm emission may experience reduced transmission through the filter. System-level testing is required to confirm optical coupling efficiency.

Q: Are there package considerations when substituting the OP216A for the SE1470-003L?

A: Yes. The SE1470-003L uses a coaxial metal can package, while the OP216A uses a radial package. These packages have different physical dimensions and lead configurations. PCB footprint redesign is necessary. Both components are through-hole mounted, so standard PCB assembly processes apply.

Q: What is the product status significance of the SE1470-003L being obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support. The SE1470-003L is no longer available from primary sources. The OP216A, classified as active, has ongoing manufacturing support, current availability, and continued compliance with evolving regulatory standards.

Q: Does the OP216A meet current environmental compliance requirements?

A: Yes. The OP216A holds ROHS3 compliance certification and is unaffected by REACH regulations. These certifications align with current environmental and regulatory requirements for electronic components in most markets.
