WB201-NFW28H Equivalent & Substitute Parts Reference

Part Overview

The WB201-NFW28H is a T-1 3/4 sub-miniature LED lamp with wedge base manufactured by Visual Communications Company (VCC). This component is designed as an LED replacement for incandescent wedge base lamps, operating at 28V forward voltage with a white color output rated at 280 millicandela. The part maintains Active product status and is RoHS3 compliant, making it suitable for general purpose lighting applications where wedge base lamps are specified. Substitute parts are identified when equivalent mechanical form factors and base types are required but alternative electrical specifications better match system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WB201-NFW28H are identified based on strict alignment of the following parameters:

Mechanical Compatibility Parameters:

• Size / Dimension: T-1 3/4 (physical envelope)
• Base Type: Wedge (socket interface)
• Configuration: Single (LED element count)

Electrical Compatibility Parameters:

• Voltage - Forward (Vf): Specified voltage rating for circuit operation
• Color: White (optical specification)

Regulatory & Supply Parameters:

• Product Status: Active (ongoing availability)
• RoHS Status: ROHS3 Compliant (environmental compliance)
• Manufacturer: Visual Communications Company (VCC)

The substitute part VC1511A25W3D shares identical mechanical form factor (T-1 3/4 wedge base) and color specification (white) with the main part. The primary difference is the forward voltage rating: VC1511A25W3D operates at 12V compared to the WB201-NFW28H at 28V. This voltage difference means these parts are suitable for different circuit applications and cannot be used interchangeably in the same electrical circuit without voltage adjustment.

Parameter Comparison

Engineering Selection Recommendations

WB201-NFW28H Selection Criteria: Select this part when the application circuit operates at 28V forward voltage and requires a T-1 3/4 wedge base white LED lamp with 280 millicandela output. This part is Active status with ROHS3 compliance and REACH Unaffected designation, confirming regulatory compliance for current manufacturing standards.

VC1511A25W3D Selection Criteria: Select this part when the application circuit operates at 12V forward voltage and requires a T-1 3/4 wedge base white LED lamp. This substitute provides 300 millicandela output, which is 20mcd higher than the main part. This part is also Active status with ROHS3 compliance and REACH Unaffected designation. The higher luminous intensity may provide improved visibility in 12V applications.

Voltage Compatibility Statement: These parts cannot be used interchangeably in the same circuit without modification to the power supply or circuit design. The 28V main part and 12V substitute are electrically distinct and require different circuit voltage levels for proper operation.

Frequently Asked Questions (FAQ)

Q: Can VC1511A25W3D replace WB201-NFW28H in my existing circuit?

A: No. The VC1511A25W3D operates at 12V forward voltage while the WB201-NFW28H operates at 28V. Direct substitution in the same circuit will result in incorrect operation. The substitute part requires a 12V power supply or circuit modification.

Q: Are both parts mechanically compatible with the same socket?

A: Yes. Both parts use T-1 3/4 form factor with wedge base configuration, making them mechanically compatible with the same socket interface. However, electrical compatibility requires matching the circuit voltage to the part's forward voltage specification.

Q: What is the brightness difference between these parts?

A: The WB201-NFW28H is rated at 280 millicandela while the VC1511A25W3D is rated at 300 millicandela. The substitute provides approximately 7% higher luminous intensity. Both parts produce white light output.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both parts are ROHS3 compliant and REACH Unaffected, confirming compliance with current environmental and regulatory requirements for electronic components.

Q: What is the packaging format for these parts?

A: Both parts are supplied in Bulk packaging. The WB201-NFW28H has 837 pieces in stock, and the VC1511A25W3D has 1213 pieces in stock.

Q: Can I use these parts in indicator light applications?

A: The WB201-NFW28H is specified for general purpose lighting. The VC1511A25W3D is specified for incandescent replacements and indicator lights. Application suitability depends on the specific circuit voltage requirement and the intended use case.

Q: What is the base product number for each part?

A: The WB201-NFW28H base product number is WB201-NFW28. The VC1511A25W3D base product number is VC1511. These base numbers identify the product family and variant series.
