Key Parameters

Substitute Part Grouping Explanation

Substitution of the 18626132 requires evaluation of the following critical parameters:

Electrical Compatibility:

• Voltage rating (130VAC for main part)
• Forward voltage (Vf) characteristics
• Millicandela output rating

Optical Compatibility:

• Wavelength specification (587nm yellow)
• Color consistency (Yellow configuration)
• LED configuration (3 Round)

Mechanical Compatibility:

• Base type (Bayonet connection)
• Physical dimensions and form factor
• Socket fit and retention

Regulatory & Environmental:

• RoHS3 compliance
• REACH status
• Moisture sensitivity level

The substitute part SSP-3MB93S12G from Lumex Opto/Components Inc. shares the following common attributes: yellow color specification (590nm wavelength), three-round LED configuration, bayonet base type, RoHS3 compliance, MSL 1 rating, and REACH unaffected status. However, critical differences exist in voltage rating (12V versus 130VAC) and physical dimensions, which affect direct substitution feasibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Assessment:

The SSP-3MB93S12G cannot serve as a direct mechanical or electrical substitute for the 18626132 due to the following factors:

1. Voltage Incompatibility: The 18626132 operates at 130VAC, while the SSP-3MB93S12G is rated for 12V DC operation. These voltage classes are fundamentally different and require separate power supply architectures.

2. Base Type Mismatch: The 18626132 uses a standard bayonet base, whereas the SSP-3MB93S12G employs a miniature bayonet (BA9S) base. These bases are not mechanically interchangeable.

3. Physical Dimension Variance: The T - 3 1/4 form factor of the 18626132 differs significantly from the 0.433" diameter x 1.063" height specification of the SSP-3MB93S12G, preventing socket compatibility.

4. Luminous Intensity Difference: The SSP-3MB93S12G provides 13200mcd output compared to the 18626132's 300mcd total output, representing a 44-fold increase in brightness unsuitable for equivalent indicator light applications.

Regulatory Compliance:

Both components maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, satisfying environmental and regulatory requirements for equivalent product categories.

Product Status Consideration:

The 18626132 is classified as obsolete. The SSP-3MB93S12G maintains active product status, indicating ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Can the SSP-3MB93S12G replace the 18626132 in existing equipment?

A: No. The SSP-3MB93S12G cannot replace the 18626132 due to incompatible voltage ratings (12V versus 130VAC), different base types (miniature bayonet versus standard bayonet), and non-matching physical dimensions. Direct substitution would require socket modification and power supply redesign.

Q: What is the primary reason these parts are not interchangeable?

A: The voltage rating difference is the primary barrier. The 18626132 operates on 130VAC mains voltage, while the SSP-3MB93S12G requires 12V DC. These represent different electrical classes requiring distinct power delivery systems.

Q: Are the wavelengths similar enough for visual equivalence?

A: The wavelengths are proximate (587nm versus 590nm), both producing yellow illumination within the human visual perception range. However, wavelength similarity alone does not establish substitution compatibility when other critical parameters diverge.

Q: What does the "3 Round" configuration mean for both parts?

A: Both components feature three individual round LEDs within a single package. This configuration provides redundancy and distributed light output. The 18626132 and SSP-3MB93S12G both employ this three-LED arrangement.

Q: Why is the SSP-3MB93S12G significantly brighter than the 18626132?

A: The SSP-3MB93S12G produces 13200mcd compared to the 18626132's 300mcd. This difference reflects distinct design objectives: the Lumex component is engineered for higher-intensity indicator applications, while the VCC component targets standard indicator light intensity levels.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both the 18626132 and SSP-3MB93S12G are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings, satisfying equivalent environmental and regulatory requirements.

Q: What is the significance of the 18626132 being classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This necessitates identification of alternative components for system maintenance and new procurement. However, obsolescence does not automatically establish substitution relationships with active products.

Q: Can the base types be adapted through mechanical modification?

A: Base type adaptation is not recommended for engineering applications. The bayonet versus miniature bayonet distinction reflects fundamental socket design differences. Mechanical modification introduces reliability risks and voids equipment compatibility assurances.
