MS200-NFW28H LED Lamp Equivalent & Substitute Parts

Part Overview

The MS200-NFW28H is a miniature screw base LED lamp (T-1 3/4 form factor) manufactured by Visual Communications Company (VCC). This component is rated at 28V forward voltage and produces 280 millicandela output in white color. The part is classified as obsolete, making identification of suitable substitute components essential for system maintenance and component procurement.

The MS200-NFW28H serves general purpose lighting applications requiring miniature screw base lamps. Due to its obsolete status, alternative parts from the same manufacturer series must be evaluated to ensure continued availability and system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS200-NFW28H is determined by the following critical parameters that must remain constant across equivalent parts:

Fixed Parameters (Non-Negotiable for Substitution):

• Base Type: Miniature Screw (E5)
• Form Factor: T-1 3/4
• Color: White
• Configuration: Single
• Millicandela Rating: 280mcd
• Application Category: General Purpose Lighting
• Compliance: ROHS3 Compliant

Variable Parameter (Allows Substitution):

• Voltage - Forward (Vf): The MS200-NFW28H operates at 28V. Substitute parts may operate at different forward voltages provided the mechanical and optical characteristics remain identical and the part is sourced from the same manufacturer series (MS200).

The MS200-NFW2 qualifies as a parametric equivalent because it maintains all fixed parameters while operating at a different forward voltage (2V). Both parts share identical mechanical mounting (Miniature Screw E5 base), identical form factor (T-1 3/4), identical color (White), and identical light output (280mcd). The voltage difference reflects different circuit application requirements but does not affect physical interchangeability or optical performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The MS200-NFW28H is classified as obsolete. The MS200-NFW2 is classified as active and maintains current manufacturing status with VCC. For new procurement and long-term system support, the MS200-NFW2 is the appropriate selection from the MS200 series.

Compliance and Certification

Both parts maintain ROHS3 compliance and carry identical ECCN (EAR99) and HTSUS classifications, confirming regulatory equivalence for export and procurement purposes.

Voltage Consideration

Selection between these parts depends on circuit voltage requirements. The MS200-NFW28H operates at 28V forward voltage, while the MS200-NFW2 operates at 2V forward voltage. The substitute part must be selected based on the actual operating voltage of the target application circuit. Both parts deliver identical optical output (280mcd) and maintain identical mechanical form factor, ensuring that the choice is purely a function of circuit voltage compatibility.

Inventory and Availability

The MS200-NFW2 is currently in active production with 1,095 pieces in stock, providing superior long-term availability compared to the obsolete MS200-NFW28H (953 pieces in stock).

Frequently Asked Questions (FAQ)

Q: Can the MS200-NFW2 be used as a direct replacement for the MS200-NFW28H?

A: Physical and optical compatibility is confirmed. Both parts use identical Miniature Screw (E5) base type, T-1 3/4 form factor, and produce 280mcd white light output. However, the forward voltage differs (2V versus 28V). Direct substitution is only appropriate if the target circuit operates at 2V. If the circuit requires 28V operation, the MS200-NFW2 will not function correctly.

Q: What are the key parameters that determine if a part can substitute for the MS200-NFW28H?

A: Substitution requires matching the following parameters: Miniature Screw (E5) base type, T-1 3/4 form factor, white color, 280mcd light output, single configuration, and general purpose lighting application category. Forward voltage may differ based on circuit requirements. All parts must maintain ROHS3 compliance.

Q: Why does the MS200-NFW2 have a different forward voltage?

A: Forward voltage is determined by the LED die and circuit design within the lamp assembly. Different voltage ratings allow the same optical and mechanical lamp design to be used across various circuit voltage standards (2V, 5V, 12V, 28V, etc.). The voltage difference does not affect the lamp's physical dimensions, base type, or light output characteristics.

Q: Is the MS200-NFW2 suitable for new designs?

A: Yes. The MS200-NFW2 carries active product status with current manufacturing support from VCC. It is appropriate for new designs requiring 2V miniature screw base white LED lamps with 280mcd output.

Q: What is the packaging difference between these parts?

A: The MS200-NFW28H is packaged in standard format. The MS200-NFW2 is packaged in bulk format. Packaging selection depends on procurement volume and inventory management requirements.

Q: Are there any compliance or export restrictions?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, indicating no differential export restrictions or compliance barriers between the two parts.
