Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCC 1050A2 is determined by the following critical parameters that must align between the main part and substitute components:

Panel Mechanical Compatibility:

• Panel cutout shape must be round
• Panel cutout dimensions must be 0.50" (12.70mm) to ensure physical fit in existing panel openings
• Lens style must be round with domed top for visual consistency and light distribution

Electrical Compatibility:

• Voltage rating must accommodate the 105V to 125V AC operating range
• Termination must be wire leads to match existing wiring infrastructure
• Wire lead length must be compatible with circuit board layout (reference length: 4.6")

Regulatory and Environmental Compliance:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) for storage and handling compatibility

The VCC 1092A2-125VAC meets these substitution criteria through equivalent panel cutout dimensions, compatible voltage rating, matching lens configuration, and identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The VCC 1092A2-125VAC serves as a functional substitute for the obsolete VCC 1050A2 based on matching mechanical panel interface specifications and electrical voltage compatibility. Both components feature identical 0.50" (12.70mm) round panel cutout dimensions and round domed lens configuration, ensuring direct physical compatibility with existing panel openings.

Compliance Considerations:

Both the main part and substitute maintain ROHS3 compliance and MSL rating of 1 (Unlimited), confirming equivalent environmental and regulatory standing for applications requiring these certifications.

Product Status Impact:

The VCC 1050A2 is classified as obsolete, while the VCC 1092A2-125VAC maintains active product status. This distinction ensures continued availability and supply chain support for the substitute component in ongoing production and maintenance scenarios.

Wire Lead Length Variance:

The substitute component features wire leads of 4.8" (121.92mm) compared to the main part's 4.6" (116.84mm). This 0.2-inch difference requires verification of circuit board layout and wiring routing to confirm adequate clearance and connection accessibility.

Frequently Asked Questions (FAQ)

Q: Can the VCC 1092A2-125VAC be used as a direct replacement for the VCC 1050A2 in existing panel assemblies?

A: Yes, the substitute component is mechanically compatible due to matching 0.50" (12.70mm) round panel cutout dimensions and identical round domed lens style. The wire lead length difference of 0.2 inches must be accommodated in circuit board routing.

Q: What is the primary functional difference between these two components?

A: The VCC 1050A2 uses neon lamp technology, while the VCC 1092A2-125VAC uses LED technology. Both provide visual indication at 125V AC operation, but LED technology offers improved energy efficiency and longer operational life.

Q: Are both components compliant with current regulatory standards?

A: Yes, both the VCC 1050A2 and VCC 1092A2-125VAC maintain ROHS3 compliance and are unaffected by REACH regulations, confirming equivalent regulatory standing.

Q: Does the voltage rating difference (105V-125V versus 125V) affect substitution suitability?

A: The substitute component's 125V rating falls within the upper range of the main part's 105V to 125V specification, ensuring electrical compatibility for standard 125V AC applications. Applications operating below 125V require confirmation that the substitute's fixed 125V rating is appropriate.

Q: What packaging format is available for the substitute component?

A: The VCC 1092A2-125VAC is supplied in bag packaging, compared to the main part's standard packaging configuration.

Q: Is the substitute component currently available for procurement?

A: Yes, the VCC 1092A2-125VAC maintains active product status with documented inventory availability, ensuring reliable supply for replacement and new design applications.
