LED Panel Indicator 655-1205-103F Equivalent & Substitute Parts

Part Overview

The Dialight 655-1205-103F is a 1/2" flat snap LED panel indicator designed for 120V AC applications. This component functions as a visual status indicator with a green lamp, 5mA current draw, and 3-inch wire leads for direct circuit integration. The part is designated as Last Time Buy, indicating limited future availability. Identifying equivalent and substitute parts ensures design continuity and supply chain reliability for applications currently utilizing this indicator.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 655-1205-103F is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Voltage rating: 120V AC
• Current consumption: 5mA
• Lamp color: Green
• Luminous intensity: 110mcd

Mechanical Compatibility:

• Panel cutout shape: Round
• Panel cutout diameter: 0.50" (12.70mm)
• Lens style: Round with Flat Top
• Termination: Wire Leads - 3" (76.20mm)

Regulatory Compliance:

• RoHS3 Compliant
• REACH Unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. No deviations from these specifications are permitted for functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 655-1205-103F and 6551205103F are manufactured by Dialight and maintain identical electrical and mechanical specifications. The parts differ only in part number formatting (hyphenated versus non-hyphenated designation) and represent the same physical component.

Both parts carry Last Time Buy status, indicating that neither represents a long-term supply solution. Selection between these parts should be based on current inventory availability and internal part number management systems. Both parts satisfy ROHS3 compliance and REACH requirements for regulated markets.

For applications requiring long-term supply assurance beyond the Last Time Buy window, evaluation of alternative LED panel indicator families from Dialight or other manufacturers with equivalent electrical and mechanical parameters is necessary.

Frequently Asked Questions (FAQ)

Q: Are 655-1205-103F and 6551205103F interchangeable?

A: Yes. These part numbers represent the same component with identical electrical ratings (120V AC, 5mA), mechanical dimensions (0.50" round cutout, 3-inch wire leads), and optical characteristics (green lamp, 110mcd). The difference is formatting of the part number designation only.

Q: What determines if a substitute part is acceptable?

A: A substitute part must match all critical parameters: 120V AC voltage rating, 5mA current consumption, green lamp color, 110mcd luminous intensity, 0.50-inch round panel cutout, round flat-top lens style, and 3-inch wire lead termination. Deviations in any of these parameters result in incompatibility.

Q: Why is this part marked Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued or will discontinue production. This designation signals that future availability is limited and existing inventory represents the final production run.

Q: Can I substitute a different voltage rating or current specification?

A: No. The 120V AC and 5mA specifications are fixed design parameters. Substitution with different voltage or current ratings will result in circuit malfunction or component failure.

Q: Are there packaging differences between these part numbers?

A: Both parts are supplied in Bag packaging. Inventory levels differ (891 pieces for 655-1205-103F versus 1181 pieces for 6551205103F), but packaging format is identical.

Q: Do both parts meet regulatory requirements?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, satisfying environmental and hazardous substance regulations for regulated markets.
