LED BAYONET MULT T3-1/4 230V GRN (18626231)

Part Overview

The Visual Communications Company (VCC) model 18626231 is an LED lamp replacement featuring a green bayonet base configuration designed for 230VAC operation. This component functions as a direct replacement for incandescent indicator lights and general illumination applications requiring a T3-1/4 form factor with bayonet mounting. The part is classified as obsolete, necessitating identification of functionally equivalent substitute components for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 18626231 requires evaluation against the following critical parameters that define functional equivalence:

Wavelength Matching: Both the original part and substitute must operate at 525nm green wavelength to maintain color consistency in indicator light applications.

Configuration: The 3 Round LED configuration must be preserved to ensure optical output characteristics and form factor compatibility.

Base Type: Bayonet base mounting is required for mechanical compatibility with existing fixtures and sockets.

Color Specification: Green (x 3) designation must be maintained across substitute selection.

RoHS and REACH Compliance: Substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements.

Moisture Sensitivity Level: MSL 1 (Unlimited) classification ensures reliability in standard operating environments.

The identified substitute part SSP-3MB92UP12G from Lumex Opto/Components Inc. shares the critical optical and mechanical parameters (wavelength, configuration, color, base type, and compliance certifications) necessary for functional substitution. However, voltage specification differs significantly and must be evaluated within the context of system design requirements.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Regulatory Status: The SSP-3MB92UP12G maintains ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements equivalent to the original 18626231 component.

Product Availability: The Lumex substitute is classified as Active product status with 1154 units in stock, providing reliable procurement availability compared to the obsolete VCC original.

Optical Characteristics: Both parts operate at identical 525nm wavelength with 3 Round green LED configuration, ensuring color consistency and optical output profile compatibility for indicator light applications.

Critical Consideration - Voltage Specification: The SSP-3MB92UP12G operates at 12V DC, whereas the original 18626231 is specified for 230VAC operation. This represents a fundamental difference in electrical interface requirements. System integration of this substitute requires verification that the application circuit can accommodate 12V DC supply and control architecture.

Base Type Variance: The substitute employs Miniature Bayonet (BA9S) base versus the original Bayonet configuration. Physical socket compatibility must be confirmed for mechanical installation.

Frequently Asked Questions (FAQ)

Q: Can the SSP-3MB92UP12G directly replace the 18626231 in existing fixtures?

A: Direct mechanical replacement depends on socket compatibility. The original uses Bayonet base while the substitute uses Miniature Bayonet (BA9S) base. Physical verification of socket type is required before installation.

Q: What is the primary difference between these two parts?

A: The original 18626231 operates at 230VAC, while the SSP-3MB92UP12G operates at 12V DC. This voltage difference requires corresponding changes to the power supply and control circuit architecture.

Q: Are the optical outputs equivalent?

A: Both parts operate at 525nm wavelength with 3 Round green LED configuration. However, the substitute provides significantly higher brightness (23000mcd versus 3 x 200mcd). Application requirements determine whether this brightness increase is acceptable or requires additional optical attenuation.

Q: Do both parts meet current regulatory standards?

A: Yes. Both the original 18626231 and substitute SSP-3MB92UP12G are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements.

Q: Why is the original part listed as obsolete?

A: The 18626231 is classified as obsolete by the manufacturer, indicating discontinued production. The Lumex SSP-3MB92UP12G is an active product with current manufacturing support.

Q: What packaging considerations apply to the substitute?

A: The SSP-3MB92UP12G is specified with dimensions of 0.433" Dia x 1.063" H (11.00mm x 27.00mm). Verification that this form factor accommodates existing mechanical mounting and thermal management requirements is necessary.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating equivalent moisture handling and storage requirements.
