LED Midget Flange Base 28V Green 5851315F

Part Overview

The Dialight 5851315F is a green LED lamp replacement designed for midget flange base applications operating at 28V. This component functions as an incandescent replacement in indicator light circuits and general lighting applications. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible green LED indicators with midget flange base configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5851315F are qualified based on the following critical parameters that determine functional compatibility:

• Base Type: Midget Flange (mechanical fit requirement)
• Size / Dimension: T - 1 3/4 (physical envelope)
• Color: Green (optical specification)
• Wavelength: 565nm (spectral output)
• Configuration: Single (electrical configuration)

The substitute parts MF200-BCG12H and MF200-BCG5H share identical mechanical form factors, optical characteristics, and base configurations. These parts differ in forward voltage rating (12V and 5V respectively versus the original 28V), making them suitable for applications where the circuit voltage can be adjusted or where lower-voltage system designs are implemented. Both substitutes maintain the same wavelength, color specification, and midget flange base type required for direct mechanical and optical replacement.

Parameter Comparison

Engineering Selection Recommendations

Selection between the available substitutes depends on circuit voltage requirements:

For 28V systems, direct voltage-matched replacement is not available among the listed substitutes. Implementation of MF200-BCG12H or MF200-BCG5H requires circuit redesign to accommodate the lower forward voltage ratings.

Both MF200-BCG12H and MF200-BCG5H are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance and supply chain continuity. The MF200-BCG12H operates at 12V with 80mcd output, while the MF200-BCG5H operates at 5V with equivalent 80mcd output. Both maintain identical mechanical compatibility and optical specifications (565nm wavelength, green color, midget flange base, T - 1 3/4 form factor).

Frequently Asked Questions (FAQ)

Q: Can MF200-BCG12H or MF200-BCG5H be used as direct drop-in replacements for the 5851315F?

A: Mechanical and optical compatibility is confirmed. Both substitutes feature identical midget flange base type, T - 1 3/4 form factor, green color, and 565nm wavelength. However, forward voltage differs (12V and 5V respectively versus 28V original), requiring circuit voltage adjustment for proper operation.

Q: What are the key parameters that determine substitution eligibility?

A: Base type (midget flange), physical size (T - 1 3/4), color (green), wavelength (565nm), and configuration (single) must match. Forward voltage can differ if the circuit design accommodates the alternative voltage rating.

Q: Are the substitute parts compliant with the same regulatory standards?

A: Yes. Both MF200-BCG12H and MF200-BCG5H are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 5851315F.

Q: What is the difference between MF200-BCG12H and MF200-BCG5H?

A: The primary difference is forward voltage: MF200-BCG12H operates at 12V, while MF200-BCG5H operates at 5V. Both deliver 80mcd output and share identical mechanical and optical specifications.

Q: Why is the 5851315F discontinued?

A: Product discontinuation at DiGi Electronics indicates end-of-life status. Active alternatives with compatible specifications are available through Visual Communications Company (VCC) in the MF200 series.
