NH00CG10 Equivalent & Substitute Parts

Part Overview

The NH00CG10 is a 10A square fuse rated for 500 VAC and 440 VDC operation, manufactured by Littelfuse Inc. and classified as NH type with fast-blow response characteristics. This component is designated as obsolete product status, requiring identification of active equivalent alternatives for continued system support and procurement.

The obsolete classification necessitates substitute part identification to maintain availability for motor protection applications and ensure uninterrupted supply chain access for existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NH00CG10 is determined by the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating - AC: 500 VAC (exact match required)
• Fuse Type: Square (exact match required)
• Class: NH (exact match required)
• Mounting Type: Requires Holder (exact match required)

The substitute part 10NHG000B meets all mandatory electrical and mechanical compatibility criteria. The DC voltage rating differential (250 VDC versus 440 VDC) represents a reduced capability that does not prevent substitution in applications where the lower DC rating is acceptable within system design parameters.

Parameter Comparison

Engineering Selection Recommendations

The 10NHG000B represents the qualified substitute for the obsolete NH00CG10 based on electrical and mechanical parameter alignment. The substitute maintains active product status with Eaton - Bussmann Electrical Division, ensuring ongoing availability and supply chain continuity.

The 10NHG000B achieves ROHS3 compliance, providing environmental regulatory advantage over the non-compliant original part. Both components carry VDE approval certification and maintain identical current, AC voltage, fuse type, and class specifications.

The reduced DC voltage rating of the substitute (250 VDC versus 440 VDC) requires system-level evaluation to confirm compatibility with existing DC circuit parameters. Applications operating exclusively at or below 250 VDC present no compatibility constraints.

Frequently Asked Questions (FAQ)

Q: Can the 10NHG000B directly replace the NH00CG10 in all applications?

A: Direct replacement is valid for applications where the system DC voltage does not exceed 250 VDC. The substitute maintains identical AC voltage rating (500 VAC), current rating (10A), fuse class (NH), and mechanical form factor. System design review is required for applications utilizing the full 440 VDC DC rating of the original part.

Q: What are the physical dimension differences between these parts?

A: The NH00CG10 measures 2.126" L x 2.020" W x 0.787" H (54.00mm x 51.30mm x 20.00mm). The 10NHG000B measures 2.126" L x 0.827" W x 1.693" H (54.00mm x 21.00mm x 43.00mm). Both require compatible NH-type fuse holders; dimensional variation may affect holder compatibility depending on holder design specifications.

Q: Are there compliance differences between the original and substitute?

A: The NH00CG10 is RoHS non-compliant, while the 10NHG000B achieves ROHS3 compliance. Both components maintain VDE approval certification. The substitute provides improved environmental regulatory alignment for new installations and system upgrades.

Q: What is the significance of the NH fuse class designation?

A: NH class designation indicates a standardized fuse form factor and electrical performance class suitable for industrial and motor protection applications. Both the original and substitute maintain NH class certification, ensuring compatibility with NH-rated fuse holders and circuit protection schemes.

Q: How does the breaking capacity specification affect substitution?

A: The NH00CG10 specifies 120kA AC and 25kA DC breaking capacity. The 10NHG000B specifies 120kA breaking capacity. Both maintain the 120kA AC rating required for 500 VAC circuits. The DC breaking capacity differential requires evaluation within specific DC circuit fault current calculations.
