LED T-3 1/4 Yellow Multi-LED Bayonet 230VAC Replacement - VC18626232

Part Overview

The VC18626232 is an LED lamp replacement module manufactured by Visual Communications Company (VCC), designed as a direct substitute for incandescent indicator lights and multi-lamp applications. This component features three yellow LEDs in a T-3 1/4 form factor with a standard bayonet base, rated for 230VAC operation. The product is classified as obsolete, necessitating identification of functionally equivalent substitute components for ongoing system maintenance and new design implementations. The module is ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VC18626232 requires strict alignment with the following critical parameters:

Mandatory Compatibility Parameters:

• Color Specification: Yellow wavelength output (587nm nominal range acceptable)
• LED Configuration: Three-LED module design
• Base Type: Bayonet connection for mechanical fit
• Voltage Rating: 230VAC operation capability
• Form Factor: T-3 1/4 or equivalent physical envelope
• Regulatory Compliance: ROHS3 and REACH status maintained

Application Constraints:

• Incandescent lamp replacement functionality
• Indicator light applications
• Multi-lamp bayonet socket compatibility

The identified substitute part SSP-3MB93S12G from Lumex Opto/Components Inc. presents a partial compatibility scenario due to voltage rating divergence (12V versus 230VAC). This substitute is suitable only for applications where the 230VAC requirement can be accommodated through external voltage regulation or where system redesign permits 12V operation.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Assessment:

The SSP-3MB93S12G does not qualify as a direct drop-in replacement for the VC18626232 due to multiple critical parameter mismatches:

1. Voltage Incompatibility: The substitute operates at 12V DC/AC, while the main part requires 230VAC. Direct socket substitution will result in component failure or non-operation.

2. Base Type Divergence: The main part uses a standard bayonet base, while the substitute employs a miniature bayonet (BA9S) connector. Physical socket compatibility cannot be assumed.

3. Form Factor Difference: The T-3 1/4 envelope differs from the 0.433" diameter specification of the substitute, affecting mechanical fit in standard lamp holders.

Regulatory Compliance:

Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and hazardous substance regulations.

Recommendation for Obsolete Part Replacement:

For applications currently using VC18626232, direct substitution requires identification of alternative yellow LED bayonet modules rated for 230VAC operation with matching form factors. The SSP-3MB93S12G is suitable only for new designs or system modifications where 12V operation is feasible and miniature bayonet sockets are available.

Frequently Asked Questions (FAQ)

Q: Can the SSP-3MB93S12G replace the VC18626232 in existing equipment?

A: No. The voltage rating mismatch (12V versus 230VAC) and base type difference (miniature bayonet versus standard bayonet) prevent direct substitution. Installation would result in component failure.

Q: What are the critical parameters for finding a true substitute for VC18626232?

A: A true substitute must meet all of the following: 230VAC voltage rating, standard bayonet base type, T-3 1/4 form factor, yellow color (587nm wavelength), three-LED configuration, and ROHS3/REACH compliance.

Q: Why does the SSP-3MB93S12G have higher millicandela rating than the main part?

A: The substitute operates at 12V with different LED technology, resulting in 13200mcd output versus 180mcd total for the three-LED VC18626232 module. This brightness difference reflects different design objectives and voltage classes.

Q: Are there mechanical compatibility issues between these parts?

A: Yes. The miniature bayonet (BA9S) base of the SSP-3MB93S12G is physically incompatible with standard bayonet sockets designed for the VC18626232. Socket adaptation is not recommended for safety and reliability reasons.

Q: What regulatory certifications should a substitute part maintain?

A: Any substitute must maintain ROHS3 compliance and REACH unaffected status to meet current environmental regulations applicable to the VC18626232.

Q: Can external voltage conversion enable use of the SSP-3MB93S12G?

A: While external voltage regulation could theoretically convert 230VAC to 12V, the base type incompatibility (miniature bayonet versus standard bayonet) remains an insurmountable mechanical barrier for direct socket substitution.
