Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5851213 is determined by strict equivalence across the following critical parameters:

• Base Type: Midget Flange (mechanical compatibility requirement)
• Size / Dimension: T - 1 3/4 (form factor requirement)
• Wavelength: 660nm (optical specification)
• Voltage - Forward (Vf) (Typ): 14V (electrical requirement)
• Millicandela Rating: 60mcd (brightness specification)
• Color: Red (functional requirement)
• Configuration: Single (electrical configuration)

The substitute part 5851213F maintains identical specifications across all critical parameters while offering active product status and improved compliance posture.
