LED Bayonet Lamp 18626131 - Equivalent & Substitute Parts

Part Overview

The Visual Communications Company (VCC) part number 18626131 is an LED bayonet lamp replacement designed for green indicator applications. This component features a T-3 1/4 form factor with a bayonet base, rated for 130VAC operation, and delivers 3 x 330mcd output across three round LED elements. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance and system support. The lamp is designed to replace incandescent bayonet lamps in indicator light applications requiring green wavelength output at 525nm.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCC 18626131 requires strict alignment with the following critical parameters:

Wavelength Compatibility: The substitute must operate at 525nm to maintain green color specification for indicator light applications.

LED Configuration: The substitute must feature a 3-element round LED configuration to match the original optical output pattern.

Base Type Compatibility: While the original uses a standard bayonet base, substitute parts may employ miniature bayonet (BA9S) bases if the mechanical envelope and socket compatibility are verified in the target application.

Voltage Operation: The original operates at 130VAC. Substitutes operating at different voltages (such as 12V) require circuit-level evaluation to determine applicability.

Luminous Intensity: The original delivers 3 x 330mcd. Substitutes with higher millicandela ratings (such as 23000mcd) provide increased brightness and may be suitable for applications where enhanced visibility is acceptable.

Compliance Certifications: All substitutes must maintain ROHS3 compliance and REACH unaffected status to meet regulatory requirements.

The Lumex Opto/Components Inc. part SSP-3MB92UP12G shares critical optical parameters (525nm wavelength, green color, 3-element configuration) but operates at 12V rather than 130VAC, requiring application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Mechanical and Electrical Replacement:

The VCC 18626131 remains available in inventory (985 units) despite obsolete classification. Direct replacement with the original part number is the preferred approach when socket compatibility and 130VAC supply voltage are confirmed in the target application.

For Active Product Substitution:

The Lumex Opto/Components Inc. SSP-3MB92UP12G (Poly-Leds™ series) is an active product offering equivalent optical characteristics (525nm wavelength, green color, 3-element configuration) with higher luminous intensity (23000mcd versus 3 x 330mcd). This substitute is applicable only in applications where:

• The circuit supply voltage can be adapted to 12V DC operation
• The miniature bayonet (BA9S) base is mechanically compatible with the lamp socket
• The increased brightness output does not create optical or functional conflicts
• ROHS3 compliance and REACH unaffected status requirements are met

Compliance Verification:

Both the original and substitute part maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component deployment.

Frequently Asked Questions (FAQ)

Q: Why is the VCC 18626131 classified as obsolete if inventory is available?

A: Obsolete classification indicates the manufacturer has discontinued production. Current inventory represents remaining stock. Once depleted, the part will no longer be available from the manufacturer.

Q: Can the Lumex SSP-3MB92UP12G directly replace the VCC 18626131 in existing equipment?

A: Direct replacement requires verification of three factors: (1) socket compatibility with miniature bayonet (BA9S) base, (2) circuit capability to supply 12V DC instead of 130VAC, and (3) acceptance of increased brightness output (23000mcd versus 3 x 330mcd). If any factor cannot be confirmed, direct substitution is not applicable.

Q: What is the significance of the wavelength specification at 525nm?

A: The 525nm wavelength defines the green color output of the LED. Both the original and substitute operate at this wavelength, ensuring color consistency for indicator light applications. Substitutes with different wavelengths would produce different colors and are not interchangeable.

Q: Why does the Lumex substitute have significantly higher millicandela rating?

A: The Lumex SSP-3MB92UP12G delivers 23000mcd total output compared to 3 x 330mcd (990mcd total) for the original. This reflects differences in LED technology, current drive capability, and optical design. Higher brightness may be beneficial in some applications but requires evaluation to ensure it does not create glare or functional issues.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the VCC 18626131 and Lumex SSP-3MB92UP12G maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and hazardous substance regulations for electronic components.

Q: What is the difference between bayonet and miniature bayonet (BA9S) bases?

A: Bayonet bases are larger general-purpose lamp bases used in standard indicator lamp sockets. Miniature bayonet (BA9S) bases are smaller, used in compact lamp applications. These bases are not mechanically interchangeable; socket compatibility must be confirmed before substitution.
