Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 655-1105-104F is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Voltage rating (120V AC), current draw (5mA), and AC ratings classification
• Mechanical Specifications: Panel cutout shape (round), panel cutout dimensions (0.50" / 12.70mm), lens style (round with flat top), and termination method (solder lug)
• Optical Specifications: Lamp color (red) and millicandela rating (60mcd)
• Compliance: RoHS3 compliance status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Variations in inventory status, MSL rating, or REACH classification do not affect substitution eligibility when all electrical, mechanical, and optical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The part number 6551105104F is a direct parametric equivalent to 655-1105-104F. Both parts are manufactured by Dialight and share identical electrical, mechanical, and optical specifications. Both components carry Last Time Buy status and ROHS3 compliance certification.

Selection between these two part numbers should be based on procurement availability and inventory status. The 655-1105-104F variant currently maintains 1109 pieces in stock, while the 6551105104F variant maintains 1019 pieces in stock. Either part satisfies the functional and compliance requirements for 120V AC LED panel indicator applications requiring 5mA current draw, red lamp color, and 60mcd brightness output.

For applications requiring long-term supply assurance, inventory levels should be evaluated against production timelines, as both variants carry Last Time Buy designation indicating no future production runs.

Frequently Asked Questions (FAQ)

Q: Are 655-1105-104F and 6551105104F interchangeable?

A: Yes. Both parts are parametric equivalents manufactured by Dialight with identical electrical ratings (120V AC, 5mA), mechanical specifications (0.50" round panel cutout, solder lug termination), and optical output (red lamp, 60mcd). They are direct substitutes for one another.

Q: What is the difference between these two part numbers?

A: The part numbers represent different formatting conventions for the same component specification. All functional and electrical parameters are identical. Differences in MSL rating and REACH status classification do not affect electrical or mechanical compatibility.

Q: Can I use these parts in new designs?

A: Both parts carry Last Time Buy status, indicating production discontinuation. New designs should evaluate long-term availability against project timelines. Current inventory levels are available, but no future production is planned.

Q: What are the critical parameters for substitution?

A: Substitution requires matching voltage rating (120V AC), current draw (5mA), lamp color (red), panel cutout dimensions (0.50" round), lens style (round with flat top), millicandela rating (60mcd), and termination method (solder lug).

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant. The 655-1105-104F lists MSL as Not Applicable, while 6551105104F lists MSL as 1 (Unlimited). Both carry EAR99 ECCN classification. These differences do not affect electrical or mechanical substitution eligibility.

Q: What is the panel cutout requirement for installation?

A: Both parts require a 0.50" (12.70mm) round panel cutout. The flat snap design accommodates standard panel thicknesses within the mechanical envelope of the component.
