Equivalent & Substitute Parts for 1051QA3 Neon Panel Indicator

Part Overview

The 1051QA3 is a neon panel indicator manufactured by Visual Communications Company (VCC), designed for AC applications in the 208V to 250V range. This component features an amber neon lamp with amber lens, round domed top styling, and quick connect termination (0.187" / 4.7mm). The part is marked as "Not For New Designs," indicating it has reached end-of-life status. This obsolescence necessitates identification of functionally equivalent alternatives for ongoing maintenance and new application development.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1051QA3 is based on the following critical parameters that must align between the original and substitute component:

Mandatory Alignment Parameters:

• Panel cutout dimensions (0.50" / 12.70mm round opening)
• Termination interface (Quick Connect 0.187" / 4.7mm)
• Voltage rating compatibility (208V ~ 250V AC range or overlapping range)
• Visual indication color (amber or orange spectrum)
• Regulatory compliance (ROHS3 Compliant, REACH Unaffected)

Allowable Variations:

• Indicator technology (neon to LED conversion acceptable)
• Lens transparency (domed to flat top acceptable)
• Current consumption (not specified for original part)
• Ingress protection rating (enhancement acceptable)

The substitute part 6561359304F from Dialight meets these criteria through equivalent mechanical fit, compatible voltage rating (230V within the AC range), matching panel cutout dimensions, quick connect termination, and identical regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The 6561359304F serves as a functional equivalent for the 1051QA3 in panel indication applications. Both components share identical panel cutout dimensions (0.50" round), compatible quick connect termination, and overlapping AC voltage ratings. The substitute maintains ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements equivalent to the original part.

Technology Transition Consideration:

The substitution involves a transition from neon to LED technology. This change results in reduced power consumption (3mA for LED versus unspecified neon current) and enhanced ingress protection (IP67/NEMA 4X rating). The LED indicator provides equivalent visual function with improved environmental durability.

Voltage Compatibility:

The substitute part rated at 230V AC operates within the original part's 208V ~ 250V AC specification range, ensuring electrical compatibility without circuit modification.

Product Lifecycle Status:

The original 1051QA3 is designated "Not For New Designs," while the 6561359304F maintains "Active" product status with ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Can the 6561359304F directly replace the 1051QA3 without panel modification?

A: Yes. Both components feature identical 0.50" (12.70mm) round panel cutout dimensions and quick connect termination interfaces. No mechanical modification is required.

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

A: The 1051QA3 uses neon lamp technology, while the 6561359304F uses LED technology. Both provide amber/orange visual indication at compatible AC voltages. The LED variant consumes less power and includes IP67/NEMA 4X ingress protection.

Q: Is the 230V rating of the substitute compatible with the original 208V ~ 250V specification?

A: Yes. The 230V rating of the 6561359304F falls within the 208V ~ 250V AC operating range of the 1051QA3, ensuring electrical compatibility.

Q: Are there regulatory compliance differences between the two parts?

A: No. Both the 1051QA3 and 6561359304F maintain identical ROHS3 compliance and REACH unaffected status.

Q: Will the visual appearance change if I substitute the 6561359304F for the 1051QA3?

A: The lens profile differs slightly. The original features a round domed top, while the substitute has a round flat top. Both maintain round geometry compatible with the 0.50" panel cutout. The color shifts from amber to orange within the same spectrum.

Q: What is the current consumption difference between these indicators?

A: The 1051QA3 neon current is not specified in available documentation. The 6561359304F LED indicator operates at 3mA, which is typical for LED panel indicators and represents significantly lower consumption than comparable neon designs.

Q: Is the 6561359304F suitable for new equipment designs?

A: Yes. The 6561359304F maintains "Active" product status with ongoing manufacturer support, making it appropriate for new design applications where the 1051QA3 is not recommended.
