• Lens style (round with flat top)
• Termination style (quick connect interface)

Electrical Compatibility:

• Operating voltage range (208V ~ 250V AC nominal)
• AC voltage rating

Physical Installation:

• Panel-mount configuration
• Quick connect terminal compatibility (0.187" / 4.7mm)

The substitute part 6561359304F from Dialight meets these mechanical and electrical compatibility criteria while offering modern LED technology as an alternative to neon lamp technology.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Existing Systems:

The 6561359304F serves as a functional substitute for the 1051QC3 based on matching mechanical interfaces and compatible AC voltage specifications. Both components feature identical 0.50" (12.70mm) round panel cutout dimensions and round flat-top lens styling, enabling direct panel-mount installation without mechanical modification.

Voltage Compatibility:

The 1051QC3 operates across 208V ~ 250V AC, while the 6561359304F is rated for 230V AC. The 230V specification of the substitute falls within the operating range of the original component, supporting compatibility in standard North American 230V AC applications.

Compliance Status:

Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for continued deployment. The 6561359304F carries active product status, ensuring ongoing availability and manufacturer support, whereas the 1051QC3 is designated "Not For New Designs."

Technology Transition:

The substitute represents a transition from neon lamp technology to LED technology. The 6561359304F provides enhanced ingress protection (IP67, NEMA 4X) compared to the original neon design, offering improved environmental sealing for panel-mount applications.

Frequently Asked Questions (FAQ)

Q: Can the 6561359304F directly replace the 1051QC3 without panel modification?

A: Yes. Both components share identical 0.50" (12.70mm) round panel cutout dimensions and round flat-top lens styling. No mechanical modification to the panel is required for installation.

Q: Are the voltage specifications compatible?

A: The 1051QC3 operates at 208V ~ 250V AC, and the 6561359304F operates at 230V AC. The 230V specification falls within the operating range of the original component, supporting compatibility in standard AC applications.

Q: What is the primary difference between these components?

A: The 1051QC3 uses neon lamp technology, while the 6561359304F uses LED technology. The LED substitute offers lower power consumption, enhanced durability, and improved ingress protection (IP67, NEMA 4X).

Q: Are both components RoHS compliant?

A: Yes. Both the 1051QC3 and 6561359304F are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the significance of the 1051QC3 being marked "Not For New Designs"?

A: This designation indicates the component has reached end-of-life status and is no longer recommended for new product development. Existing systems using this component should transition to active alternatives such as the 6561359304F for long-term supply chain stability.

Q: Does the substitute offer any additional features?

A: The 6561359304F provides IP67 and NEMA 4X ingress protection ratings, offering enhanced environmental sealing compared to the original neon design. This makes it suitable for applications requiring higher moisture and contamination resistance.

Q: Are the termination styles compatible?

A: Both components use quick connect termination. The 1051QC3 specifies 0.187" (4.7mm) quick connect, and the 6561359304F uses quick connect termination, supporting direct electrical connection without adapter requirements.
