VC1512145W3 LED T1 3/4 Midget Groove White 28VDC Equivalent & Substitute Parts

Part Overview

The VC1512145W3 is an LED lamp replacement component manufactured by Visual Communications Company (VCC) in the VC15121 series. This white LED features a T-1 3/4 form factor with midget groove base configuration, designed for 28VDC operation. The component serves as a direct replacement for incandescent indicator lights and is classified as Active product status with full ROHS3 compliance and REACH unaffected designation. Substitute parts are identified when system voltage requirements differ or inventory availability necessitates alternative voltage-rated configurations within the same mechanical and optical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VC1512145W3 are determined by strict equivalence in the following parameters: form factor (T-1 3/4), base type (midget groove), color (white), millicandela rating (700mcd), configuration (single), and application category (incandescent replacements and indicator lights). The primary variable parameter is forward voltage (Vf), which defines the operating system voltage. Substitute parts maintain identical mechanical, optical, and compliance characteristics while accommodating different voltage system requirements. All substitute parts are members of the VC15121 series and retain Active product status with ROHS3 compliance and REACH unaffected designation.

Parameter Comparison

Engineering Selection Recommendations

Selection between VC1512145W3, VC1512135W3, and VC1512125W3 is determined exclusively by system voltage requirements. The VC1512145W3 operates at 28VDC and is selected for 28-volt systems. The VC1512135W3 operates at 24VDC and is selected for 24-volt systems. The VC1512125W3 operates at 12VDC and is selected for 12-volt systems. All three parts maintain identical mechanical compatibility (T-1 3/4 form factor with midget groove base), optical output (700mcd white), and regulatory compliance (ROHS3 compliant, REACH unaffected). Component selection must align with the installed system voltage to ensure proper LED operation and longevity. All parts carry Active product status and are suitable for direct substitution within their respective voltage classes.

Frequently Asked Questions (FAQ)

Q: Can VC1512135W3 (24V) be used in place of VC1512145W3 (28V)?

A: No. These components are voltage-specific. The VC1512135W3 is rated for 24VDC operation and cannot be substituted in a 28VDC system. Voltage mismatch will result in improper LED operation.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical form factor (T-1 3/4), base type (midget groove), and physical dimensions. Mechanical interchangeability is confirmed. Electrical compatibility depends on system voltage matching.

Q: What is the primary difference between VC1512145W3, VC1512135W3, and VC1512125W3?

A: The primary difference is forward voltage rating. VC1512145W3 is rated 28V, VC1512135W3 is rated 24V, and VC1512125W3 is rated 12V. All other specifications including color, brightness (700mcd), base type, and form factor are identical.

Q: Do all substitute parts have the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Regulatory compliance is uniform across the VC15121 series variants.

Q: What applications are these LED components designed for?

A: These components are designed for incandescent lamp replacement and indicator light applications. They maintain the same form factor and base configuration as traditional incandescent T-1 3/4 midget groove lamps.

Q: Are these parts available in bulk packaging?

A: Yes. All parts are supplied in bulk packaging. Current inventory includes 874 pcs of VC1512145W3, 1390 pcs of VC1512135W3, and 1660 pcs of VC1512125W3.
