Engineering Selection Recommendations

For applications currently using the Dialight 5855315, the following selection criteria apply:

5855315F is the direct successor within the Dialight product line. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The transition from the obsolete 5855315 to the 5855315F represents a direct upgrade path with no functional changes to the application.

5855325F provides parametric equivalence across all critical electrical and mechanical parameters. This part also carries active product status and ROHS3 compliance. Selection between 5855315F and 5855325F depends on inventory availability and procurement requirements, as both parts satisfy the same functional and compliance criteria.

Both substitute parts are available in bulk packaging and maintain the same REACH unaffected status and ECCN classification as the original component.

Frequently Asked Questions (FAQ)

Q: Can the 5855315F directly replace the obsolete 5855315?

A: Yes. The 5855315F maintains identical specifications across base type, size, wavelength, voltage, color, and brightness rating. No circuit modifications are required.

Q: What is the difference between 5855315F and 5855325F?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is the base product number designation within the Dialight 585 series. Both are active products with ROHS3 compliance.

Q: Are there compliance differences between the original 5855315 and the substitute parts?

A: Yes. The original 5855315 is RoHS non-compliant. Both substitute parts (5855315F and 5855325F) are ROHS3 compliant, meeting current regulatory requirements.

Q: Does packaging affect substitution eligibility?

A: No. Both substitute parts are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Can these parts be used interchangeably in the same application?

A: Yes. All three parts share identical base type (BA9S), size (T-3 1/4), wavelength (565nm), voltage (28V), color (green), and brightness (490mcd). They are mechanically and electrically interchangeable.
