Key Parameters

Substitute Part Grouping Explanation

Substitution of the NH00CG35 is determined by the following critical parameters:

• Current Rating: 35A (exact match required)
• Voltage Rating - AC: 500 VAC (exact match required)
• Fuse Class: NH (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Package / Case: Rectangular, Blade (exact match required)

The substitute part 35NHG000B meets all critical electrical and mechanical parameters. While dimensional variations exist in the width and height specifications, both parts maintain the same 54.00mm length and are compatible with standard NH-class fuse holders. The substitute is manufactured by Eaton - Bussmann Electrical Division and carries active product status with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 35NHG000B from Eaton - Bussmann Electrical Division is the qualified substitute for the obsolete NH00CG35. Selection is based on:

• Identical current rating, AC voltage rating, fuse class, and response characteristics
• Active product status ensuring ongoing availability and supply chain continuity
• RoHS compliance status, which addresses regulatory requirements for new installations and replacements
• Dual certification (CE and VDE) providing broader regulatory acceptance compared to the original part's VDE-only certification
• Compatibility with standard NH-class fuse holders despite dimensional variations in width and height

Frequently Asked Questions (FAQ)

Q: Can the 35NHG000B be used as a direct replacement for the NH00CG35?

A: Yes. Both parts share identical current rating (35A), AC voltage rating (500 VAC), fuse class (NH), response time (Fast Blow), and mounting requirements. The dimensional differences in width and height do not affect compatibility with standard NH-class fuse holders.

Q: What is the significance of the dimensional differences between these parts?

A: The 35NHG000B has different width (0.827" vs 2.020") and height (1.693" vs 0.787") specifications compared to the NH00CG35. However, both maintain the same 54.00mm length and rectangular blade package configuration. These variations are within the tolerance range for NH-class fuse holder compatibility.

Q: Why is RoHS compliance important for this substitution?

A: The NH00CG35 is RoHS non-compliant, while the 35NHG000B is RoHS compliant. For new installations or systems subject to RoHS regulations, the substitute part ensures regulatory compliance. For legacy system maintenance, either part may be acceptable depending on local regulatory requirements.

Q: Does the 35NHG000B support DC voltage operation?

A: The 35NHG000B specifications do not explicitly list a DC voltage rating, whereas the NH00CG35 is rated for 440 VDC. For applications requiring DC operation at 440V, verify the 35NHG000B's DC capability with the manufacturer or consider alternative substitutes that explicitly specify DC voltage ratings.

Q: Are there any approval agency differences between these parts?

A: The NH00CG35 carries VDE approval only. The 35NHG000B carries both CE and VDE approvals, providing broader regulatory acceptance in European and international markets.
