Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1051A2 neon panel indicator is determined by the following critical parameters:

Mechanical Compatibility:

• Panel cutout shape and dimensions (Round, 0.50" / 12.70mm)
• Lens style (Round with Domed Top)
• Termination type (Wire Leads)

Electrical Compatibility:

• Voltage rating (208V ~ 250V AC range)
• Ratings classification (AC)

Regulatory Compliance:

• RoHS3 Compliance
• REACH Unaffected status

The substitute part 1092A2-250VAC meets these critical parameters. While the 1092A2-250VAC represents a technology transition from neon to LED, it maintains mechanical fit within the same 0.50-inch panel cutout and operates within the specified voltage range. Both components share identical panel mounting geometry and wire lead termination methodology.

Parameter Comparison

Engineering Selection Recommendations

For 1051A2 Replacement:

The 1092A2-250VAC serves as the active substitute for the obsolete 1051A2. Both components are manufactured by VCC and maintain identical panel mounting geometry (0.50-inch round cutout). The substitute operates at 250V AC, which falls within the original 208V ~ 250V specification range.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for new installations and system upgrades.

The transition from neon to LED technology in the 1092A2-250VAC provides operational advantages including reduced power consumption (25mA rating) and extended service life, while preserving mechanical and electrical compatibility with existing panel cutouts and wiring infrastructure.

Frequently Asked Questions (FAQ)

Q: Can the 1092A2-250VAC directly replace the 1051A2 in existing installations?

A: Yes. Both components share identical panel cutout dimensions (0.50 inches / 12.70mm round) and lens style (round with domed top). Wire lead termination is compatible, with the substitute providing 4.8 inches versus the original 4.6 inches. The 250V AC rating of the substitute falls within the original 208V ~ 250V specification.

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

A: The 1051A2 uses neon lamp technology, while the 1092A2-250VAC uses LED technology. Both are clear-colored indicators with identical mechanical mounting specifications.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 1051A2 and 1092A2-250VAC are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.

Q: Does the wire lead length difference affect installation?

A: The 1092A2-250VAC provides 4.8 inches of wire leads compared to 4.6 inches on the original 1051A2. This 0.2-inch difference accommodates standard panel mounting applications without requiring circuit modifications.

Q: What is the current consumption of the substitute part?

A: The 1092A2-250VAC operates at 25mA, providing defined current specifications compared to the original neon design.
