Equivalent & Substitute Parts for 1051QA1 Neon Panel Indicator

Part Overview

The 1051QA1 is a neon panel indicator manufactured by Visual Communications Company (VCC), designed for AC applications in the 208V to 250V range. This component features a red neon lamp with a round domed lens and quick connect termination suitable for 0.50" (12.70mm) panel cutouts.

The 1051QA1 carries a "Not For New Designs" product status, indicating that VCC has discontinued active development and support for this series. Organizations requiring equivalent functionality for new installations or replacement applications must evaluate suitable substitute components that maintain compatibility with existing panel mounting infrastructure and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 1051QA1 must satisfy the following mandatory criteria:

Electrical Compatibility:

• Voltage rating must accommodate the 208V to 250V AC operating range
• AC-rated electrical specifications required
• Termination must be Quick Connect style at 0.187" (4.7mm) connector

Mechanical Compatibility:

• Panel cutout shape must be round
• Panel cutout dimensions must be 0.50" (12.70mm) to fit existing mounting holes
• Lens style should be round with domed top for form factor consistency

Functional Requirements:

• Red lamp color and red lens color for indication consistency
• RoHS3 compliance for regulatory alignment

The 6563109304F from Dialight meets these substitution criteria through equivalent mechanical mounting, compatible voltage specifications, and matching termination style, while offering enhanced specifications including defined current draw and ingress protection ratings.

Parameter Comparison

Engineering Selection Recommendations

For Replacement Applications: The 6563109304F serves as a direct mechanical and electrical substitute for the 1051QA1 in existing panel installations. Both components share identical panel cutout dimensions (0.50" round), compatible quick connect termination, and equivalent voltage specifications. The 6563109304F operates at 230V AC, which falls within the 1051QA1 voltage range of 208V to 250V.

For New Designs: The 1051QA1 carries "Not For New Designs" status. The 6563109304F is classified as "Active" product status, making it the appropriate selection for new installations requiring equivalent functionality. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements.

Technology Consideration: The primary difference between these components is lamp technology: the 1051QA1 uses neon technology while the 6563109304F uses LED technology. Both deliver red indication through compatible lens colors and styles. The 6563109304F provides additional specifications including defined current draw (3mA) and ingress protection ratings (IP66/IP67, NEMA 4X), which may provide operational advantages in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the 6563109304F directly replace the 1051QA1 in existing installations?

A: Yes. Both components feature identical 0.50" (12.70mm) round panel cutout dimensions and quick connect termination. The 6563109304F operates at 230V AC, which is within the 1051QA1 voltage specification range of 208V to 250V AC. Mechanical and electrical compatibility is confirmed.

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

A: The 1051QA1 uses neon lamp technology, while the 6563109304F uses LED technology. Both deliver red indication and share compatible mechanical mounting and electrical termination specifications.

Q: Why is the 1051QA1 marked "Not For New Designs"?

A: This designation indicates that VCC has discontinued active development and support for the 1051QA series. For new installations, the 6563109304F is recommended as it carries "Active" product status and receives ongoing manufacturer support.

Q: Are both components RoHS3 compliant?

A: Yes. Both the 1051QA1 and 6563109304F are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: Does the 6563109304F provide any additional specifications compared to the 1051QA1?

A: The 6563109304F provides defined current draw (3mA) and ingress protection ratings (IP66/IP67, NEMA 4X). The 1051QA1 does not specify these parameters in available documentation.

Q: What is the lens transparency difference?

A: The 1051QA1 lens transparency is not specified. The 6563109304F specifies clear lens transparency, allowing full light transmission through the red lens color.
