Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5851323 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)
• Color: Green (optical specification)
• Wavelength: 565nm (spectral output requirement)
• Voltage - Forward (Vf) (Typ): 14V (electrical compatibility requirement)
• Millicandela Rating: 56mcd (brightness specification)
• Configuration: Single (electrical configuration)
• Applications: Incandescent Replacements, Indicator Lights (functional category)

The substitute part 5851323F meets all these parameters identically, establishing direct functional and mechanical equivalence. The primary distinction between the main part and its substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5851323F is the direct active equivalent for the obsolete 5851323. Both parts share identical electrical, optical, and mechanical specifications, ensuring drop-in compatibility in midget flange base lamp applications requiring 14V green indicator operation at 56mcd brightness.

The 5851323F offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the 5851323F carries ROHS3 compliance certification, whereas the original 5851323 is RoHS non-compliant. This compliance improvement may be relevant for applications subject to environmental regulatory requirements.

Both parts maintain identical moisture sensitivity classification (MSL 1 - Unlimited) and REACH unaffected status, indicating equivalent handling and regulatory positioning in these categories.

Frequently Asked Questions (FAQ)

Q: Can the 5851323F directly replace the 5851323 in existing installations?

A: Yes. The 5851323F is electrically and mechanically equivalent to the 5851323.
