Dialight 5855413 LED Cluster T3 1/4 Yellow 525nm 14V Equivalent & Substitute Parts

Part Overview

The Dialight 5855413 is an LED lamp replacement cluster in T-3 1/4 form factor with yellow emission at 525nm wavelength and 14V forward voltage. Designed as an incandescent replacement for indicator lights and general lighting applications, this part features a bayonet base configuration. The product is currently obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility with existing installations and new designs requiring this specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5855413 is determined by the following critical parameters: form factor (T-3 1/4), base type (bayonet configuration), wavelength (525nm yellow), forward voltage (14V), and millicandela rating (420mcd). These parameters define mechanical fit, electrical compatibility, and optical performance in the target application.

Two substitute parts are identified:

Direct Manufacturer Substitute (5855413F): Maintains identical form factor, base type classification, and series designation. However, this part specifies Miniature Bayonet (BA9S) base type, which differs from the standard bayonet base of the original part. Wavelength, forward voltage, and millicandela rating are not specified for this variant, indicating potential parameter differences.

Parametric Equivalent (5855423F): Provides complete parameter alignment with the original part, including T-3 1/4 form factor, bayonet base type, 525nm wavelength, 14V forward voltage, and 420mcd millicandela rating. This part maintains functional equivalence across all specified electrical and optical parameters.

Parameter Comparison

Engineering Selection Recommendations

For direct parameter matching and mechanical compatibility: Part 5855423F is the appropriate selection. This part maintains complete electrical and optical specification alignment with the original 5855413, including bayonet base type, 525nm wavelength, 14V forward voltage, and 420mcd output. The part is currently active in production and carries ROHS3 compliance certification, addressing regulatory requirements for new designs and procurement.

For base type consideration: Part 5855413F shares the direct manufacturer designation and series lineage but introduces a Miniature Bayonet (BA9S) base type, which differs from the standard bayonet configuration of the original part. The absence of specified wavelength, forward voltage, and millicandela rating parameters for this variant requires mechanical and electrical verification before application in existing installations.

Both substitute parts are available in bulk packaging and carry REACH Unaffected status. The transition from RoHS non-compliant status (original part) to ROHS3 compliance (both substitutes) reflects current regulatory alignment for active production components.

Frequently Asked Questions (FAQ)

Q: Can 5855413F directly replace 5855413 in existing applications?

A: Part 5855413F differs in base type specification (Miniature Bayonet BA9S versus standard Bayonet). Mechanical compatibility with existing bayonet sockets cannot be confirmed without physical verification. Electrical and optical parameters are not specified for this variant.

Q: Is 5855423F a complete functional equivalent?

A: Yes. Part 5855423F maintains all specified parameters: T-3 1/4 form factor, bayonet base type, 525nm wavelength, 14V forward voltage, and 420mcd millicandela rating. This part provides parametric equivalence for direct substitution.

Q: What is the difference between "Direct Manufacturer Substitute" and "Parametric Equivalent"?

A: Direct Manufacturer Substitute (5855413F) shares the same manufacturer and series but introduces a different base type. Parametric Equivalent (5855423F) maintains complete specification alignment across all electrical, optical, and mechanical parameters.

Q: Are the substitute parts RoHS compliant?

A: Both 5855413F and 5855423F carry ROHS3 Compliant certification, whereas the original 5855413 is RoHS non-compliant. This compliance upgrade is relevant for new designs and procurement in regulated markets.

Q: What packaging options are available for the substitute parts?

A: Both substitute parts are supplied in bulk packaging. The original part packaging specification was not provided.

Q: Do the substitute parts have the same moisture sensitivity rating?

A: Yes. All three parts (original and both substitutes) carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints for storage and handling.
