SE1450-001 Infrared Emitter 935nm Equivalent & Substitute Parts

Part Overview

The SE1450-001 is an infrared (IR) emitter manufactured by Honeywell Sensing and Productivity Solutions, designed for 935nm wavelength applications requiring 50mA forward current operation. 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 part is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure long-term supply chain reliability for new production and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SE1450-001 is determined by strict alignment of the following critical electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Wavelength: 935nm
• Maximum Forward Current (If): 50mA
• Typical Forward Voltage (Vf): 1.6V
• Component Type: Infrared (IR) Emitter

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Orientation: Top View

Acceptable Variations:

• Viewing Angle: Substitute parts may have narrower viewing angles (18° acceptable for 24° original)
• Operating Temperature Range: Substitute parts may have narrower ranges provided minimum operating temperature does not exceed application requirements
• Package / Case: Different through-hole package styles (T-1 acceptable for Coaxial, Metal Can)
• Product Status: Active parts preferred over obsolete

The OP165D from TT Electronics/Optek Technology meets all critical electrical parameters and mounting requirements, making it a valid functional substitute despite differences in package geometry and viewing angle.

Engineering Selection Recommendations

Primary Substitute: OP165D

The OP165D is the recommended substitute for SE1450-001 applications based on the following engineering criteria:

1. Electrical Equivalence: Identical wavelength (935nm), maximum forward current (50mA), and typical forward voltage (1.6V) ensure functional compatibility at the component level.

2. Product Status: OP165D maintains active product status with 973 units in stock, providing reliable long-term availability compared to the obsolete SE1450-001.

3. Compliance: Both components meet RoHS requirements. OP165D carries ROHS3 Compliant certification and is REACH Unaffected, satisfying current regulatory standards.

4. Mounting Compatibility: Both components use through-hole mounting with top-view orientation, enabling direct circuit board integration without redesign of mounting footprints.

5. Package Consideration: The OP165D uses T-1 package geometry instead of coaxial metal can. PCB layout modifications may be required to accommodate the different physical form factor.

6. Operating Temperature: OP165D operates within -40°C to 100°C range. Applications requiring operation below -40°C or above 100°C must evaluate alternative solutions or implement thermal management strategies.

7. Viewing Angle: OP165D provides 18° viewing angle versus 24° for SE1450-001. Applications requiring wider beam dispersion must assess optical performance impact.

Frequently Asked Questions (FAQ)

Q: Can OP165D directly replace SE1450-001 without circuit modifications?

A: OP165D provides electrical equivalence and identical mounting type. However, the T-1 package differs physically from the coaxial metal can package. PCB layout modifications are required to accommodate the different package geometry. Electrical circuit connections remain unchanged.

Q: What is the impact of the narrower 18° viewing angle in OP165D compared to 24° in SE1450-001?

A: The 18° viewing angle is narrower, resulting in more concentrated radiant intensity in the forward direction. Applications requiring wide-angle IR emission may experience reduced performance. Optical system redesign or alternative component selection should be evaluated for wide-angle applications.

Q: Does OP165D operate across the full temperature range of SE1450-001?

A: No. OP165D operates from -40°C to 100°C, while SE1450-001 operates from -55°C to 125°C. Applications requiring operation below -40°C or above 100°C cannot use OP165D without additional thermal management or alternative component selection.

Q: Are both components RoHS compliant?

A: Yes. SE1450-001 is RoHS Compliant, and OP165D is ROHS3 Compliant. Both meet current RoHS requirements. OP165D additionally carries REACH Unaffected status.

Q: What is the radiant intensity specification for OP165D?

A: OP165D specifies radiant intensity of 0.28mW/cm² at 20mA forward current. SE1450-001 does not provide radiant intensity data in the available specifications.

Q: Are there inventory considerations for component selection?

A: SE1450-001 has 784 units in stock but is obsolete with no future production. OP165D has 973 units in stock and maintains active product status, ensuring continued availability for future orders.

Q: What certifications apply to OP165D?

A: OP165D carries ROHS3 Compliant certification, REACH Unaffected status, and EAR99 export classification. Both components share EAR99 ECCN and 8541.41.0000 HTSUS codes.
