Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1051C4 is based on the following critical parameters that must align between the original and substitute component:

Mechanical Compatibility:

• Panel cutout shape and dimensions (0.50-inch round opening)
• Lens style (round with flat top configuration)
• Termination method (wire leads for direct connection)

Electrical Compatibility:

• AC voltage rating within or overlapping the 208V to 250V range
• Lamp color output (white)
• Lens color (white)

Regulatory and Environmental:

• ROHS3 compliance
• REACH unaffected status
• Moisture sensitivity level 1 (unlimited)

The substitute part 6561009303F from Dialight meets these critical parameters while offering an active product status and enhanced specifications including LED technology, improved brightness (400mcd), and IP66/IP67 ingress protection rating.

Parameter Comparison

Engineering Selection Recommendations

The 1051C4 is classified as obsolete, making the 6561009303F a suitable substitute for ongoing applications requiring panel-mounted white indicators in AC circuits.

Compatibility Assessment:

Both components share identical panel cutout dimensions (0.50 inches round) and lens configuration (round with flat top), enabling direct mechanical installation in existing panel openings without modification.

The 6561009303F operates at 230V AC, which falls within the upper range of the 1051C4 specification (208V to 250V), ensuring electrical compatibility in most standard AC applications.

Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement and deployment.

Operational Differences:

The 6561009303F utilizes LED technology rather than neon, resulting in lower power consumption (3mA specified current) and extended operational life compared to neon-based indicators. The LED variant provides quantified brightness output (400mcd) and enhanced environmental protection (IP66/IP67, NEMA 4X ratings).

Wire lead length differs between components: the 1051C4 provides 4.6-inch leads while the 6561009303F provides 5.84-inch leads. Installation verification is required to confirm adequate lead length for existing wiring configurations.

Frequently Asked Questions (FAQ)

Q: Can the 6561009303F directly replace the 1051C4 without panel modification?

A: Yes. Both components feature identical 0.50-inch round panel cutout dimensions and round flat-top lens styles, enabling direct mechanical installation in existing panel openings.

Q: Is the 230V rating of the 6561009303F compatible with 208V to 250V applications?

A: The 230V rating of the 6561009303F falls within the upper portion of the 1051C4 voltage range (208V to 250V). Compatibility depends on the specific circuit voltage. For 208V applications, verification with the circuit design is required.

Q: What is the significance of the different wire lead lengths?

A: The 1051C4 provides 4.6-inch leads while the 6561009303F provides 5.84-inch leads. Existing wiring harnesses and connection points must accommodate the longer leads of the substitute component, or lead trimming may be necessary.

Q: Are both components compliant with current environmental regulations?

A: Yes. Both the 1051C4 and 6561009303F maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Q: What are the operational advantages of LED technology over neon?

A: The 6561009303F LED indicator operates at lower current (3mA) compared to typical neon consumption, provides quantified brightness output (400mcd), and includes enhanced environmental protection ratings (IP66/IP67, NEMA 4X).

Q: Is the 1051C4 still available for procurement?

A: The 1051C4 carries an obsolete product status. The 6561009303F is classified as active and represents the current available alternative for this application category.
