Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1510145UG3 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Base Type: Midget Flange (mechanical fit requirement)
• Size / Dimension: T - 1 3/4 (physical envelope)
• Color: Green (optical specification)
• Wavelength: 525nm (spectral output)
• Configuration: Single (electrical configuration)
• Voltage - Forward (Vf) (Typ): 28V (electrical operation requirement)

Secondary Compliance Criteria:

• RoHS3 Compliance
• REACH Unaffected status
• Millicandela Rating: 910mcd (luminous intensity)

Substitute parts must match all primary criteria to ensure direct replacement capability. The 1510145UG3 can be substituted with active equivalent parts that maintain identical electrical voltage specifications, physical dimensions, base type, and optical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (28V Applications):

The VC1510145UG3 is the active equivalent substitute for the obsolete 1510145UG3. Both parts share identical electrical specifications (28V forward voltage), physical dimensions (T - 1 3/4), optical characteristics (525nm green wavelength, 910mcd), and base type (midget flange). The VC1510145UG3 maintains full ROHS3 compliance and REACH unaffected status. This part is currently in active production status with confirmed inventory availability.

Parametric Alternative (24V Applications):

The VC1510135UG3 is a parametric equivalent that differs only in forward voltage specification (24V versus 28V). This part is suitable for applications operating at 24V DC where the 28V specification of the main part is not required. The VC1510135UG3 maintains all other critical parameters including physical dimensions, optical output, base type, and compliance certifications. Selection of this alternative requires confirmation that the application circuit operates at 24V nominal voltage.

Compliance Status:

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part specifications.

Frequently Asked Questions (FAQ)

Q: Can VC1510145UG3 be used as a direct replacement for the obsolete 1510145UG3?

A: Yes. The VC1510145UG3 is the active equivalent substitute. Both parts share identical forward voltage (28V), physical dimensions (T - 1 3/4), wavelength (525nm), base type (midget flange), and luminous intensity (910mcd). Mechanical and electrical compatibility is confirmed.

Q: What is the difference between VC1510145UG3 and VC1510135UG3?

A: The primary difference is forward voltage specification. VC1510145UG3 operates at 28V DC, while VC1510135UG3 operates at 24V DC. All other parameters including physical size, color, wavelength, base type, and luminous intensity are identical. Selection depends on the application circuit voltage requirement.

Q: Can VC1510135UG3 be used in a 28V circuit?

A: No. The VC1510135UG3 is specified for 24V DC operation. Using this part in a 28V circuit exceeds its forward voltage rating and will result in component failure or reduced operational life.

Q: Are both substitute parts available in the same packaging?

A: Both VC1510145UG3 and VC1510135UG3 are supplied in bulk packaging. Packaging specifications should be confirmed with the supplier for specific application requirements.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both VC1510145UG3 and VC1510135UG3 are ROHS3 compliant and REACH unaffected, matching the compliance status of the original 1510145UG3.

Q: What is the midget flange base type?

A: Midget flange is a standardized mechanical base configuration for T-series LED lamps. This base type ensures physical compatibility with fixtures designed for midget flange lamp sockets. Both substitute parts use this identical base type.

Q: Can these parts replace incandescent lamps?

A: Yes. Both substitute parts are specified for incandescent lamp replacement applications. The LED technology provides equivalent optical output (910mcd) with improved reliability and reduced power consumption compared to incandescent alternatives.
