VC1510145W3 LED T1 3/4 White 28VDC Equivalent & Substitute Parts

Part Overview

The VC1510145W3 is an LED lamp replacement component manufactured by Visual Communications Company (VCC) in the VC15101 series. This white LED operates at 28VDC and features a midget flange base in a T-1 3/4 form factor. The component is designed as an incandescent replacement for indicator light applications and maintains Active product status with full RoHS3 compliance.

Substitute parts are identified when system requirements change, inventory constraints occur, or alternative voltage specifications are needed while maintaining identical mechanical and optical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VC1510145W3 are qualified based on the following criteria:

Mechanical Compatibility Parameters:

• Identical size and dimension (T - 1 3/4)
• Identical base type (Midget Flange)
• Same series designation (VC15101)
• Identical configuration (Single)

Optical Compatibility Parameters:

• Identical color (White)
• Identical millicandela rating (700mcd)

Electrical Compatibility Parameters:

• Forward voltage (Vf) may vary based on system design requirements
• All parts operate within the VC15101 series voltage range

Compliance and Environmental Parameters:

• RoHS3 Compliant status maintained across all substitutes
• MSL rating of 1 (Unlimited) consistent across all parts
• REACH Unaffected status maintained

The primary variable parameter enabling substitution is the forward voltage specification. Parts within this group are interchangeable when the system voltage requirement matches the part's rated voltage.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts from the VC15101 series must be based on the system's operating voltage specification. All three parts maintain identical mechanical form factors, optical output characteristics, and regulatory compliance status.

VC1510145W3 (28VDC): Primary selection for 28-volt DC systems. Active product status with 1176 units in stock.

VC1510135W3 (24VDC): Substitute for 24-volt DC systems. Active product status with 1068 units in stock. Maintains all mechanical and optical specifications of the primary part.

VC1510125W3 (12VDC): Substitute for 12-volt DC systems. Active product status with 1476 units in stock. Maintains all mechanical and optical specifications of the primary part.

All parts carry ROHS3 compliance certification and REACH Unaffected status, qualifying them for use in regulated applications. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can VC1510135W3 (24V) be used in place of VC1510145W3 (28V)?

A: No. These parts have different forward voltage ratings. The VC1510135W3 is specified for 24VDC operation, while the VC1510145W3 is specified for 28VDC operation. Using an incorrect voltage-rated part will result in improper circuit operation.

Q: Are all three parts mechanically identical?

A: Yes. All parts in the VC15101 series share identical T-1 3/4 form factors and midget flange base types. They are mechanically interchangeable when voltage requirements are met.

Q: Do all substitute parts have the same light output?

A: Yes. All three parts maintain a 700mcd millicandela rating and white color specification. Optical output is identical across the series.

Q: What is the difference between these parts?

A: The only difference is the forward voltage specification. VC1510145W3 operates at 28V, VC1510135W3 at 24V, and VC1510125W3 at 12V. All other electrical, mechanical, and optical parameters are identical.

Q: Are these parts RoHS compliant?

A: Yes. All parts in this group are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates that these components have no moisture sensitivity constraints. They can be stored and handled without special moisture control measures.

Q: Can I substitute parts between different voltage ratings in the same circuit?

A: No. Each part must match the circuit's voltage specification. Substitution is only valid when the replacement part's voltage rating matches the system requirement.
