Dialight 5851123 LED Midget Flange Red 14V Equivalent & Substitute Parts

Part Overview

The Dialight 5851123 is an LED-based red indicator lamp with midget flange base designed for 14V operation. This component functions as a direct replacement for incandescent midget flange base lamps in indicator light applications. The part is classified as obsolete, making identification of active equivalent models essential for procurement and system maintenance. The 5851123F represents the current active production equivalent within the Dialight 585 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5851123 is determined by the following critical parameters:

• Base Type: Midget Flange (mechanical compatibility requirement)
• Voltage - Forward (Vf): 14V (electrical compatibility requirement)
• Color: Red (functional requirement for indicator applications)
• Configuration: Single (circuit integration requirement)

The Dialight 5851123F qualifies as a direct substitute based on matching all four critical parameters. The transition from obsolete to active product status, combined with improved RoHS3 compliance in the substitute part, supports this equivalency for new designs and replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5851123F is the appropriate substitute for the obsolete 5851123 in applications requiring a red LED midget flange base lamp at 14V operation. The substitute part maintains electrical and mechanical compatibility while offering improved regulatory compliance through ROHS3 certification. Both parts share identical export classification (EAR99) and tariff coding (8541.41.0000), supporting seamless procurement transitions.

For systems currently using the 5851123, direct replacement with the 5851123F is supported by matching voltage, base type, color, and configuration specifications. The active product status of the 5851123F ensures continued availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 5851123F directly replace the 5851123 in existing installations?

A: Yes. Both parts share identical voltage (14V), base type (midget flange), color (red), and configuration (single) specifications. Physical and electrical compatibility is maintained.

Q: What is the primary difference between these parts?

A: The 5851123 is obsolete with RoHS non-compliant status, while the 5851123F is an active production part with ROHS3 compliance. Both maintain identical electrical and mechanical parameters.

Q: Are there packaging differences between the main part and substitute?

A: The 5851123 is supplied in standard packaging, while the 5851123F is supplied in bulk packaging. This does not affect component functionality or compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are classified as REACH Unaffected and carry EAR99 export classification. The 5851123F provides enhanced compliance through ROHS3 certification, while the 5851123 is RoHS non-compliant.

Q: What applications are these parts suitable for?

A: Both parts function as incandescent lamp replacements in indicator light applications requiring red 14V midget flange base lamps.
