Key Parameters

Substitute Part Grouping Explanation

Substitution for the Dialight 5855313 is determined by strict equivalence across the following critical parameters:

• Base Type: Miniature Bayonet (BA9S)
• Size / Dimension: T - 3 1/4
• Wavelength: 565nm (green spectrum)
• Voltage - Forward (Vf) (Typ): 14V
• Millicandela Rating: 420mcd
• Configuration: Single
• Color: Green

Two substitute parts meet these criteria. The 5855313F is a direct manufacturer equivalent with identical electrical and mechanical specifications but in bulk packaging and active product status. The 5855323F is a parametric equivalent offering the same functional performance with non-polarized LED-based lamp design, also in active status.

Parameter Comparison

Engineering Selection Recommendations

The 5855313F is the primary substitute for the obsolete 5855313. Both parts share identical electrical and mechanical specifications with matching 420mcd output, 565nm wavelength, and 14V forward voltage. The 5855313F carries active product status and ROHS3 compliance, addressing regulatory requirements where applicable.

The 5855323F provides an alternative parametric equivalent with identical performance characteristics. This part is also active and ROHS3 compliant, offering non-polarized LED-based lamp design. Selection between 5855313F and 5855323F depends on packaging requirements and application-specific constraints, as both meet the core electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5855313F directly replace the obsolete 5855313?

A: Yes. The 5855313F matches all critical parameters: 14V forward voltage, 565nm wavelength, 420mcd output, T - 3 1/4 size, and miniature bayonet (BA9S) base type. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between the 5855313F and 5855323F?

A: Both parts are parametric equivalents with identical electrical performance (14V, 565nm, 420mcd, BA9S base). The 5855323F is specified as a non-polarized LED-based lamp design. Selection depends on application requirements and packaging availability.

Q: Are there packaging differences between these substitutes?

A: The original 5855313 uses standard packaging. The 5855313F and 5855323F are supplied in bulk packaging. Verify packaging requirements for your application before selection.

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

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

Q: Are the substitute parts suitable for incandescent replacement applications?

A: The 5855313F is specified for incandescent replacements and indicator lights. The 5855323F is specified for general purpose lighting and incandescent replacements. Both are suitable for the intended application.
