Dialight 5855215F LED Cluster Equivalent & Substitute Parts

Part Overview

The Dialight 5855215F is an active-status LED lamp replacement featuring a red miniature bayonet (BA9S) base, designed for general purpose lighting applications. This T-3 1/4 form factor LED operates at 28V forward voltage with a 660nm wavelength and 560mcd brightness rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in compatible fixture designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5855215F are identified based on strict parameter matching across electrical and mechanical specifications. The critical parameters determining substitution eligibility are:

• Base Type: Miniature Bayonet (BA9S)
• Size / Dimension: T-3 1/4
• Color: Red
• Wavelength: 660nm
• Voltage - Forward (Vf) (Typ): 28V
• Millicandela Rating: 560mcd
• Configuration: Single

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The 5855215F has two identified substitute parts: 5855225F and 5855256F, both from the Dialight 585 series.

Parameter Comparison

Engineering Selection Recommendations

All three parts—5855215F, 5855225F, and 5855256F—maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts should be based on inventory availability and application requirements. The 5855225F offers 970 units in stock, the 5855256F provides 1224 units, and the 5855215F has 930 units available. All parts are suitable for general purpose lighting applications requiring miniature bayonet base LED replacements with 28V forward voltage operation.

Frequently Asked Questions (FAQ)

Q: Can the 5855225F directly replace the 5855215F? A: Yes. Both parts share identical electrical and mechanical parameters, including 28V forward voltage, 660nm wavelength, 560mcd brightness, T-3 1/4 form factor, and miniature bayonet base type.

Q: What determines if a part is a valid substitute? A: Valid substitutes must match all critical parameters: base type (BA9S), size (T-3 1/4), color (red), wavelength (660nm), forward voltage (28V), and brightness rating (560mcd).

Q: Are all substitute parts in the same packaging format? A: Yes. The 5855215F, 5855225F, and 5855256F are all supplied in bulk packaging.

Q: Do the substitute parts have the same compliance certifications? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (unlimited).

Q: What is the difference between the part numbers if they are substitutes? A: The part numbers reflect different manufacturing batches or internal Dialight designations within the 585 series. Electrical and mechanical specifications remain equivalent.
