Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5855423 is determined by strict alignment of the following parameters:

• Wavelength: 525nm (yellow spectrum)
• Voltage - Forward (Vf): 14V
• Base Type: Bayonet
• Size / Dimension: T - 3 1/4
• Millicandela Rating: 420mcd
• Configuration: Single
• Color: Yellow

Parts meeting all these criteria are classified as direct substitutes. The Dialight 5855423F qualifies as a direct substitute based on identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5855423F is the direct substitute for the obsolete Dialight 5855423. Both parts share identical electrical and mechanical specifications, ensuring functional equivalence in bayonet base LED lamp replacement applications.

The 5855423F offers the advantage of active product status and ROHS3 compliance, making it the preferred selection for new designs and ongoing maintenance where regulatory compliance is required. The main part (5855423) is no longer in active production.

Both parts maintain REACH Unaffected status and EAR99 ECCN classification. Moisture sensitivity level is rated at MSL 1 (Unlimited) for both variants.
