SE3455-004 Infrared Emitter 935nm Equivalent & Substitute Parts

Part Overview

The SE3455-004 is an infrared (IR) emitter manufactured by Honeywell Sensing and Productivity Solutions, operating at 935nm wavelength with a maximum forward current of 100mA. The device is housed in a TO-46-2 metal can package with a 90° viewing angle and operates across the temperature range of -55°C to 125°C. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SE3455-004 is determined by the following critical parameters:

Primary Matching Criteria:

• Wavelength: 935nm (exact match required)
• Type: Infrared (IR) Emitter
• Mounting Type: Through Hole
• Current Rating: 100mA maximum (or lower with circuit adjustment)
• Package Compatibility: TO-46-2 or equivalent form factor

Secondary Compatibility Factors:

• Forward voltage tolerance: ±0.15V acceptable for circuit design
• Viewing angle: Application-dependent; narrower angles (18°) suitable for focused applications; wider angles (90°) for broad-spectrum coverage
• Operating temperature range: Substitute must cover or exceed the application's required temperature window
• RoHS and regulatory compliance status

The three substitute parts (OP130, OP133W, OP165W) all share the 935nm wavelength and through-hole mounting. However, they differ in current rating, viewing angle, and package variant, requiring application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

OP130 (TT Electronics/Optek Technology)

The OP130 provides the closest electrical match to the SE3455-004, with identical 100mA maximum forward current and 935nm wavelength. Forward voltage is 1.75V versus 1.7V, a 0.05V difference within typical circuit tolerance. The primary distinction is the narrower 18° viewing angle compared to the SE3455-004's 90° angle. The OP130 is housed in a TO-46-2 Lens Top Metal Can package and carries Active product status with ROHS3 compliance. This substitute is suitable for applications requiring focused IR emission with maintained current capacity.

OP133W (TT Electronics/Optek Technology)

The OP133W matches the SE3455-004 in wavelength and maximum forward current (100mA), with forward voltage of 1.75V. It provides a 50° viewing angle, intermediate between the SE3455-004's 90° and the OP130's 18°. The OP133W is packaged in a standard TO-46-2 Metal Can and is Active with ROHS3 compliance. This substitute accommodates applications requiring moderate beam divergence with full current capacity.

OP165W (TT Electronics/Optek Technology)

The OP165W operates at 935nm with a 90° viewing angle matching the SE3455-004's optical characteristics. However, the maximum forward current is 50mA, half that of the SE3455-004. Forward voltage is 1.6V, 0.1V lower than the original. The OP165W is packaged in a T-1 form factor rather than TO-46-2, requiring mechanical redesign. Operating temperature range is -40°C to 100°C, narrower than the SE3455-004's -55°C to 125°C. This substitute is applicable only where reduced current operation is acceptable and the T-1 package is mechanically compatible.

All three substitutes carry Active product status and current RoHS compliance, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can OP130 directly replace SE3455-004 in existing designs?

A: Electrical substitution is feasible due to matching wavelength, current rating, and forward voltage within tolerance. However, the narrower 18° viewing angle of OP130 versus SE3455-004's 90° requires optical system verification. Mechanical compatibility with TO-46-2 Lens Top Metal Can packaging must be confirmed against the original TO-46-2 Metal Can footprint.

Q: What is the primary difference between OP130, OP133W, and OP165W?

A: The three substitutes differ in viewing angle and current rating. OP130 provides 18° with 100mA; OP133W provides 50° with 100mA; OP165W provides 90° with 50mA. Wavelength and basic package type remain constant at 935nm and through-hole mounting. Selection depends on optical beam requirements and available drive current in the application circuit.

Q: Is OP165W suitable as a direct replacement?

A: OP165W matches the SE3455-004's 90° viewing angle and forward voltage characteristics. However, the 50mA maximum current is half the original specification, and the T-1 package differs from TO-46-2, requiring circuit redesign and mechanical modification. Use OP165W only when reduced current operation is acceptable and package change is feasible.

Q: What are the temperature range implications?

A: SE3455-004 operates from -55°C to 125°C. OP130 and OP133W extend the lower limit to -65°C, providing broader low-temperature coverage. OP165W is limited to -40°C to 100°C, narrower than the original. For applications requiring the full -55°C to 125°C range, OP130 or OP133W are preferred.

Q: Are all substitutes RoHS compliant?

A: Yes. SE3455-004 is RoHS Compliant. OP130, OP133W, and OP165W all carry ROHS3 Compliant status, ensuring regulatory alignment for new designs and ongoing support.

Q: What packaging considerations apply?

A: SE3455-004 uses TO-46-2 Metal Can. OP130 uses TO-46-2 Lens Top Metal Can (similar footprint with optical lens). OP133W uses standard TO-46-2 Metal Can (direct mechanical fit). OP165W uses T-1 package (different form factor, requires mechanical redesign). Verify PCB layout and mechanical clearance before selection.

Q: Can forward voltage differences affect circuit operation?

A: SE3455-004 has 1.7V typical forward voltage. OP130 and OP133W are 1.75V; OP165W is 1.6V. These differences are within typical circuit tolerance for current-limited drive circuits. Verify series resistor values and power supply voltage to confirm adequate headroom and current delivery across the voltage range.
