NH00CG16 Equivalent & Substitute Parts

Part Overview

The NH00CG16 is a 16A 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, which necessitates identification of functionally equivalent alternatives for ongoing system maintenance and new designs. The part features VDE approval and is designed for motor protection applications requiring an indicating fuse with holder mounting.

Key Parameters

Substitute Part Grouping Explanation

The 16NHG000B from Eaton - Bussmann Electrical Division qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

• Current Rating: Both parts rated at 16A
• Voltage Rating - AC: Both rated at 500 VAC
• Fuse Type: Both are square fuses
• Class: Both classified as NH type
• Mounting Type: Both require holder mounting
• Package / Case: Both use rectangular blade configuration
• Approval Agency: Both carry VDE approval
• Breaking Capacity: 16NHG000B rated at 120kA AC, meeting the AC requirement

The primary electrical difference is the DC voltage rating: NH00CG16 is rated for 440 VDC while 16NHG000B is rated for 250 VDC. This represents a reduction in maximum DC voltage capability. The 16NHG000B is active product status with RoHS compliance, whereas the NH00CG16 is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The 16NHG000B is suitable as a substitute for the obsolete NH00CG16 in applications where the DC voltage requirement does not exceed 250 VDC. Both parts maintain identical AC voltage ratings (500 VAC), current ratings (16A), and NH class specifications. The 16NHG000B offers the advantage of active product status and RoHS compliance, supporting long-term supply chain continuity and regulatory alignment.

For applications requiring the full 440 VDC rating of the original NH00CG16, alternative sources must be evaluated, as the 16NHG000B DC voltage capability is limited to 250 VDC. The mechanical compatibility is confirmed through identical package and case specifications (Rectangular, Blade) and holder mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can the 16NHG000B replace the NH00CG16 in all applications?

A: The 16NHG000B is electrically compatible for AC applications and DC applications up to 250 VDC. If your circuit operates at DC voltages between 250 VDC and 440 VDC, the 16NHG000B does not meet the voltage requirement and alternative parts must be sourced.

Q: Are the physical dimensions compatible?

A: Both parts use rectangular blade package configuration and require holder mounting. However, the physical dimensions differ: NH00CG16 measures 2.126" L x 2.020" W x 0.787" H, while 16NHG000B measures 2.126" L x 0.827" W x 1.693" H. Verify that your fuse holder accommodates the 16NHG000B dimensions before installation.

Q: What is the difference in response time between these parts?

A: The NH00CG16 is specified as fast-blow response. The 16NHG000B response time is not provided in the available data. Confirm response time compatibility with your application requirements before substitution.

Q: Does the 16NHG000B meet current regulatory requirements?

A: Yes, the 16NHG000B is RoHS compliant and carries active product status, supporting compliance with current environmental and supply chain regulations. The NH00CG16 is RoHS non-compliant and obsolete.

Q: Are both parts VDE approved?

A: Yes, both the NH00CG16 and 16NHG000B carry VDE approval certification.
