Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Dialight 5851413 is determined by strict adherence to the following electrical and mechanical parameters:

• Base Type: Midget Flange (mechanical interface requirement)
• Voltage - Forward (Vf): 14V (electrical operating specification)
• Color: Yellow (optical specification)
• Wavelength: 585nm (optical specification)
• Size / Dimension: T - 1 3/4 (physical form factor)
• Millicandela Rating: 23mcd (luminous intensity specification)
• Configuration: Single (lamp configuration)

The substitute part 5851413F maintains identical electrical, optical, and mechanical specifications while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 5851413F serves as the direct functional equivalent to the obsolete 5851413. Both components share identical electrical specifications (14V forward voltage), optical characteristics (585nm wavelength, 23mcd intensity), mechanical interface (midget flange base), and physical form factor (T - 1 3/4).

The primary distinction between these components is product status and regulatory compliance. The 5851413F maintains active product status within the Dialight 585 series, ensuring ongoing availability and supply chain continuity. Additionally, the 5851413F achieves ROHS3 compliance, whereas the original 5851413 is RoHS non-compliant. Both components maintain identical moisture sensitivity ratings and REACH status.

For applications requiring RoHS3 compliance or where long-term component availability is a consideration, the 5851413F is the appropriate selection. The electrical and mechanical compatibility between these components permits direct substitution without circuit modification or system redesign.

Frequently Asked Questions (FAQ)

Q: Can the 5851413F directly replace the 5851413 in existing applications?
