Substitute Part Grouping Explanation

Substitute parts for the Dialight 5855515 are determined by strict equivalence across the following critical parameters:

• Base Type: Miniature Bayonet (BA9S)
• Size / Dimension: T - 3 1/4
• Color: Yellow
• Wavelength: 592nm
• Voltage - Forward (Vf) (Typ): 28V
• Millicandela Rating: 2100mcd
• Configuration: Single

The substitute parts identified maintain identical electrical and mechanical specifications, ensuring direct functional compatibility in applications originally designed for the 5855515. Substitutes are grouped by product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete Dialight 5855515, both 5855515F and 5855525F provide direct functional equivalence with identical electrical and mechanical parameters.

5855515F is the preferred substitute, maintaining the same base product number designation while offering active product status and ROHS3 compliance. This part is available in bulk packaging with 1057 units in stock.

5855525F serves as an alternative parametric equivalent with identical performance specifications. This part carries ROHS3 compliance and maintains active product status with 985 units in stock.

Both substitute parts satisfy regulatory requirements through ROHS3 compliance and REACH unaffected status, addressing environmental and compliance considerations for new designs or system upgrades.

Frequently Asked Questions (FAQ)

Q: Can 5855515F directly replace the obsolete 5855515?

A: Yes. The 5855515F maintains identical electrical specifications (28V forward voltage, 2100mcd output, 592nm wavelength), mechanical dimensions (T - 3 1/4), and base type (BA9S miniature bayonet). The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant).

Q: What is the difference between 5855515F and 5855525F?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The distinction lies in the base product number designation (5855515 versus 5855525). Both are active products with ROHS3 compliance and equivalent performance ratings.

Q: Are there packaging differences between substitute parts?

A: The main part 5855515 is listed with standard packaging, while both substitutes (5855515F and 5855525F) are available in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Do the substitute parts meet current regulatory standards?

A: Yes. Both 5855515F and 5855525F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original 5855515 is RoHS non-compliant, making the substitutes suitable for applications requiring regulatory compliance.

Q: What applications are these parts suitable for?

A: These LED lamp replacements are designed for incandescent replacements and indicator light applications requiring 28V operation with yellow illumination at 592nm wavelength.
