Substitute Part Grouping Explanation

Substitution for the Dialight 5855425 is determined by strict equivalence across the following critical parameters:

• Physical Form Factor: T-3 1/4 size and bayonet base type ensure mechanical compatibility with existing lamp sockets
• Electrical Specifications: 28V forward voltage and single configuration maintain circuit compatibility
• Optical Output: 585nm wavelength and 490mcd brightness rating preserve functional performance in indicator light applications
• Environmental Compliance: RoHS and REACH status determine suitability for regulated applications

The substitute parts listed below maintain identical electrical and mechanical parameters to the original 5855425, ensuring direct functional replacement without circuit modification.

Parameter Comparison

Engineering Selection Recommendations

5855425F is the direct substitute for the obsolete 5855425. Both parts share identical base product lineage within the Dialight 585 series. The 5855425F maintains all electrical and mechanical specifications while offering active product status and ROHS3 compliance, making it suitable for new designs and regulated applications.

5855415F provides parametric equivalence with identical optical, electrical, and mechanical performance. As an active product with ROHS3 compliance, it serves as an alternative when 5855425F availability is constrained. The base product number difference (5855415 versus 5855425) reflects manufacturing variants within the same functional class.

Both substitute parts are packaged in bulk format and maintain unlimited moisture sensitivity rating, consistent with the original component's environmental specifications.

Frequently Asked Questions (FAQ)
