Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 120MBL-G-CG is determined by the following critical parameters:

Mandatory Matching Parameters:

• Size / Dimension: T - 3 1/4
• Base Type: Bayonet
• Color: Green
• Can Replace Lamps: Multiple Bayonet Base Lamps
• RoHS Status: ROHS3 Compliant

Variable Parameter:

• Voltage - Forward (Vf) (Typ): Substitutes may operate at different voltage ratings (120V, 48V, or other specified voltages) depending on the application circuit requirements.

The 1835LS2-G-CG qualifies as a parametric equivalent because it maintains identical physical form factor (T-3 1/4 bayonet), color specification (green), and regulatory compliance (ROHS3), while offering an alternative voltage rating (48V) suitable for different circuit architectures.

Parameter Comparison

Engineering Selection Recommendations

For 120V Applications: The 120MBL-G-CG remains the specified component for installations operating at 120V AC. Current inventory of 1023 pieces is available in new original condition.

For 48V DC Applications: The 1835LS2-G-CG is the appropriate selection for systems operating at 48V DC. This substitute maintains identical physical and optical characteristics while accommodating lower voltage circuit requirements. The 1835LS2-G-CG carries an "Active" product status, indicating ongoing manufacturer support and availability (858 pieces in current inventory).

Regulatory Compliance: Both components satisfy ROHS3 compliance and REACH unaffected status, permitting use in regulated markets without additional certification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1835LS2-G-CG physically replace the 120MBL-G-CG in the same socket?

A: Yes. Both components share identical T-3 1/4 form factor and bayonet base type, ensuring mechanical compatibility with the same fixture interface.

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

A: The operating voltage differs. The 120MBL-G-CG operates at 120V AC, while the 1835LS2-G-CG operates at 48V DC. Selection depends on the circuit voltage specification of the installation.

Q: Are both parts suitable for new equipment designs?

A: The 120MBL-G-CG carries "Not For New Designs" status. The 1835LS2-G-CG carries "Active" status and is suitable for new designs requiring 48V DC operation.

Q: Do these parts have identical optical output?

A: Both components produce green illumination in T-3 1/4 configuration for general purpose lighting applications. Millicandela ratings are not specified in the available technical data for either component.

Q: Are there any moisture sensitivity considerations?

A: No. Both components list Moisture Sensitivity Level as "Not Applicable," indicating no special moisture handling requirements during storage or installation.

Q: What is the HTSUS classification for these components?

A: Both the 120MBL-G-CG and 1835LS2-G-CG are classified under HTSUS code 8541.41.0000.
