MS502-W120-CW LED Lamp T-4 1/2 Screw 120V Cool White Equivalent & Substitute Parts

Part Overview

The MS502-W120-CW is a miniature screw base LED lamp designed for general purpose lighting applications operating at 120VAC. This component features a T-4 1/2 form factor with cool white color output and a millicandela rating of 2 x 2500mcd. The part is classified as "Not For New Designs," indicating it is a legacy product. Identifying equivalent and substitute parts is necessary for maintenance applications, field replacements, and inventory management where the original part may be unavailable or where active product alternatives are preferred for long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS502-W120-CW is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Voltage rating: 120VAC (exact match required)
• Millicandela rating: 2 x 2500mcd (exact match required)

Mechanical Parameters:

• Base type: Miniature Screw (E10) (exact match required)
• Form factor: T - 4 1/2 (exact match required)

Optical Parameters:

• Color: White, Cool (exact match required)

Regulatory & Compliance Parameters:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99
• HTSUS: 8541.41.0000

The MS502-W120-SL2 meets all critical electrical, mechanical, optical, and regulatory parameters and is therefore a parametric equivalent substitute for the MS502-W120-CW.

Parameter Comparison

Engineering Selection Recommendations

The MS502-W120-SL2 is a direct parametric equivalent to the MS502-W120-CW. Both parts share identical electrical specifications (120VAC), mechanical form factor (T-4 1/2 Miniature Screw E10 base), optical characteristics (White, Cool color, 2 x 2500mcd), and regulatory compliance status (ROHS3 Compliant, REACH Unaffected).

The primary distinction is product status: the MS502-W120-CW is designated "Not For New Designs," while the MS502-W120-SL2 carries "Active" status. For applications requiring long-term supply chain continuity and ongoing manufacturer support, the MS502-W120-SL2 is the preferred selection. Both parts are suitable for direct substitution in existing installations and maintenance scenarios where the MS502-W120-CW is currently deployed.

Frequently Asked Questions (FAQ)

Q: Can the MS502-W120-SL2 be used as a direct replacement for the MS502-W120-CW?

A: Yes. The MS502-W120-SL2 is a parametric equivalent. All critical electrical parameters (120VAC), mechanical specifications (T-4 1/2, Miniature Screw E10 base), optical output (White, Cool, 2 x 2500mcd), and regulatory certifications (ROHS3, REACH) are identical. Direct substitution is supported without circuit or mechanical modifications.

Q: What is the difference between the MS502-W120-CW and MS502-W120-SL2?

A: The parts are electrically and mechanically identical. The difference is in product lifecycle status: MS502-W120-CW is "Not For New Designs," while MS502-W120-SL2 is "Active." The suffix designation (-CW versus -SL2) indicates different packaging or configuration variants within the same base product family (MS502-W120).

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the MS502-W120-CW and MS502-W120-SL2 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status of these parts?

A: MS502-W120-CW: 972 Pcs New Original In Stock. MS502-W120-SL2: 863 Pcs New Original In Stock. Both are available in bulk packaging.

Q: Can these lamps replace other miniature screw lamps?

A: Both the MS502-W120-CW and MS502-W120-SL2 are capable of replacing multiple miniature screw lamps that share identical electrical voltage (120VAC), base type (E10), form factor (T-4 1/2), and optical specifications (White, Cool, 2 x 2500mcd).
