Substitute Part Grouping Explanation

Substitution of the Dialight 655-1405-104F is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Voltage rating (120V AC), current draw (5mA), and lamp color (Blue)
• 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: Millicandela rating (25mcd)
• Compliance: RoHS3 compliance status

The substitute part identified maintains identical electrical, mechanical, and optical characteristics, ensuring direct functional replacement without circuit modification or panel redesign.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part number 655-1405-104F and the substitute 6551405104F are manufactured by Dialight and carry identical electrical, mechanical, and optical specifications. The difference between these part numbers represents a formatting variation in the manufacturer's part numbering system rather than a functional distinction.

Both parts maintain ROHS3 compliance and are classified as Last Time Buy products. Selection between these part numbers should be based on current inventory availability and procurement lead times, as they are functionally interchangeable for all applications requiring a 120V AC, 5mA blue LED panel indicator with a 0.50" round panel cutout and solder lug termination.

Frequently Asked Questions (FAQ)

Q: Are the part numbers 655-1405-104F and 6551405104F truly equivalent?

A: Yes. Both parts are manufactured by Dialight and share identical electrical ratings (120V AC, 5mA), mechanical specifications (0.50" round panel cutout, solder lug termination), optical output (25mcd blue LED), and compliance certifications (ROHS3).
