Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCC 1051C1 neon panel indicator is determined by the following critical parameters that must align between the original and substitute component:

Panel Integration Parameters:

• Panel cutout shape (Round)
• Panel cutout dimensions (0.50" / 12.70mm diameter)
• Lens style (Round with Flat Top)
• Termination style (Wire leads with compatible length)

Electrical Parameters:

• Voltage rating compatibility (208V ~ 250V AC range)
• Lamp color (Red)
• Lens color (Red)
• AC rating requirement

Compliance Parameters:

• RoHS3 compliance
• REACH compliance status

The VCC 1092C1-250VAC qualifies as a substitute based on matching panel cutout dimensions, lens style, color specifications, AC rating, and compliance certifications. The transition from neon to LED technology represents a functional upgrade while maintaining mechanical and electrical compatibility within the specified voltage range.

Parameter Comparison

Engineering Selection Recommendations

The VCC 1092C1-250VAC serves as the direct substitute for the 1051C1 neon panel indicator. Both components maintain identical panel cutout dimensions (0.50" round), matching lens style (round with flat top), and equivalent color specifications (red lamp and lens). Both components carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The 1092C1-250VAC holds Active product status, contrasting with the 1051C1's Not For New Designs classification. This active status ensures ongoing availability and manufacturing support. The substitute operates at 250V AC, which falls within the original component's 208V to 250V range, providing full voltage compatibility.

The wire lead length differs slightly (4.8" versus 4.6"), representing a 0.2-inch increase. This minor dimensional variance accommodates standard installation practices and does not compromise panel mounting integrity given the round cutout geometry.

The transition from neon to LED technology introduces operational differences including reduced power consumption and extended service life, while maintaining the same visual indication function and mechanical interface.

Frequently Asked Questions (FAQ)

Q: Can the 1092C1-250VAC directly replace the 1051C1 in existing equipment?

A: Yes. Both components share identical panel cutout dimensions (0.50" round), matching lens style (round with flat top), and equivalent color specifications. The 250V AC rating of the substitute falls within the original component's 208V to 250V operating range. Wire lead length increases by 0.2 inches, which does not affect panel mounting compatibility.

Q: What are the key differences between these two components?

A: The primary difference is the lamp technology: the 1051C1 uses neon, while the 1092C1-250VAC uses LED. The substitute operates at a fixed 250V AC rating compared to the original's 208V to 250V range. The 1092C1-250VAC carries Active product status, ensuring continued availability, whereas the 1051C1 is classified as Not For New Designs.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the 1051C1 and 1092C1-250VAC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the wire lead length difference affect installation?

A: The 1092C1-250VAC wire leads measure 4.8 inches compared to the 1051C1's 4.6 inches, a difference of 0.2 inches. This minor variation accommodates standard wiring practices and does not compromise panel mounting or electrical connections.

Q: What is the current rating of the substitute component?

A: The 1092C1-250VAC operates at 25mA, providing the electrical specification for circuit design and power supply sizing.

Q: Why is the original component classified as Not For New Designs?

A: The 1051C1 neon indicator has reached end-of-life status. VCC recommends the 1092C1-250VAC LED substitute for new equipment designs while supporting the original component for existing system maintenance.
