MF200-NWR28H LED Lamp T-1 3/4 Flange Equivalent & Substitute Parts

Part Overview

The MF200-NWR28H is an active production LED lamp replacement designed for midget flange base applications. This red LED lamp operates at 28V forward voltage and delivers 2800 millicandela output in a T-1 3/4 form factor. The part is manufactured by Visual Communications Company (VCC) and is suitable for general purpose lighting applications requiring midget flange base compatibility. Substitute parts are identified when inventory constraints, lead time requirements, or system voltage specifications necessitate alternative component selection while maintaining functional equivalence within the MF200 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the MF200 series is determined by strict adherence to the following parameters:

Fixed Parameters (Non-Negotiable for Substitution):

• Series: MF200
• Size / Dimension: T-1 3/4
• Base Type: Midget Flange
• Color: Red
• Wavelength: 634nm
• Millicandela Rating: 2800mcd
• Configuration: Single
• RoHS Status: ROHS3 Compliant

Variable Parameter (Substitution Basis):

• Voltage - Forward (Vf) (Typ): 28V or 24V

The MF200-NWR28H operates at 28V forward voltage. The identified substitute, MF200-NWR24H, operates at 24V forward voltage. Both parts maintain identical mechanical, optical, and electrical configuration characteristics. Substitution is valid only when the system voltage specification permits operation at the alternative forward voltage rating. No other parameter variations are permitted within this substitution group.

Engineering Selection Recommendations

Primary Selection Criteria:

1. System Voltage Specification: The forward voltage rating must match the circuit design specification. The MF200-NWR28H is specified for 28V systems. The MF200-NWR24H is specified for 24V systems. Selection must align with the actual operating voltage of the target application.

2. Product Status and Availability: Both parts maintain Active product status with current manufacturing support. MF200-NWR28H has 623 pieces in stock; MF200-NWR24H has 808 pieces in stock. Selection may be influenced by inventory availability and lead time requirements.

3. Compliance Requirements: Both parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Both satisfy equivalent environmental and regulatory requirements for general purpose lighting applications.

4. Mechanical and Optical Compatibility: Both parts are mechanically and optically identical. Socket compatibility, form factor, color output, and luminous intensity are equivalent across the substitution pair.

Selection Logic: Choose MF200-NWR28H for 28V circuit applications. Choose MF200-NWR24H only when the system voltage specification is 24V and the 28V part cannot be used due to voltage mismatch.

Frequently Asked Questions (FAQ)

Q: Can MF200-NWR24H be used as a direct replacement for MF200-NWR28H?

A: Direct replacement is not applicable. The parts differ in forward voltage specification (24V vs. 28V). Substitution is valid only when the target system operates at 24V. Using a 24V lamp in a 28V circuit or vice versa will result in incorrect operation and potential component failure.

Q: Are the mechanical dimensions identical between MF200-NWR28H and MF200-NWR24H?

A: Yes. Both parts use T-1 3/4 form factor with midget flange base. Socket compatibility and physical fit are identical.

Q: Do both parts produce the same light output?

A: Yes. Both parts deliver 2800 millicandela at 634nm wavelength (red color). Optical output is identical.

Q: What is the primary difference between these two parts?

A: The forward voltage rating is the only difference. MF200-NWR28H operates at 28V; MF200-NWR24H operates at 24V. All other electrical, mechanical, and optical characteristics are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical regulatory classifications (ECCN EAR99, HTSUS 8541.41.0000).

Q: Which part should I select for a new design?

A: Selection depends on the system voltage specification. Determine whether your circuit operates at 28V or 24V, then select the corresponding part number. Both parts are in active production with equivalent support status.

Q: Can I use either part interchangeably in inventory?

A: No. Parts must be segregated by voltage rating. Mixing parts with different forward voltage ratings in the same application will cause functional failure. Maintain separate inventory bins for each voltage variant.
