GMC-10A Equivalent & Substitute Parts Reference

Part Overview

The GMC-10A is a 10 A 125 V AC/DC glass cartridge fuse with a 5mm x 20mm form factor manufactured by Eaton - Electronics Division. This component is classified as obsolete, indicating discontinued production and limited availability through standard distribution channels. The GMC-10A requires a dedicated fuse holder for installation and operates with medium blow response characteristics. Due to its obsolete status, identifying functionally equivalent active production alternatives is essential for system maintenance, repair, and new design implementations where this fuse type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GMC-10A is determined by strict equivalence across the following critical parameters:

• Current Rating: 10 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Response Time: Medium Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 200 A (exact match required)
• Melting I²t: 300 (exact match required)
• DC Cold Resistance: 0.007 Ohms (exact match required)

The GMC-10A has one direct substitute: GMC-10-R, which maintains identical electrical and mechanical specifications while offering active production status and improved regulatory compliance. The GMC-10-R further enables cross-substitution with additional equivalent part numbers: 0233010.MXP, BK/GMC-10-R, BK1/GMC-10-R, 0232010.MX125P, and 0233010.MXBP.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: GMC-10-R

The GMC-10-R is the direct active production equivalent of the GMC-10A. All electrical and mechanical parameters are identical, ensuring functional interchangeability within existing fuse holder assemblies. The GMC-10-R carries active product status, confirming ongoing manufacturing and availability through distribution channels. The transition from RoHS non-compliant to ROHS3 compliant status provides regulatory advantage for new installations and systems subject to environmental compliance requirements.

Secondary Equivalents: 0233010.MXP, BK/GMC-10-R, BK1/GMC-10-R, 0232010.MX125P, 0233010.MXBP

These part numbers maintain identical electrical and mechanical specifications and are functionally equivalent to both GMC-10A and GMC-10-R. Selection among these alternatives is determined by packaging requirements, supplier availability, and specific procurement specifications. All secondary equivalents carry active production status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can GMC-10-R directly replace GMC-10A in existing applications?

A: Yes. The GMC-10-R maintains identical current rating (10 A), voltage rating (125 V AC), fuse type (cartridge, glass), package dimensions (5mm x 20mm), response time (medium blow), breaking capacity (200 A), melting I²t (300), and DC cold resistance (0.007 Ohms). Physical and electrical compatibility is complete. The GMC-10-R operates in the same fuse holder assembly without modification.

Q: What is the difference between GMC-10A and GMC-10-R?

A: The primary differences are product status and regulatory compliance. GMC-10A is obsolete with RoHS non-compliant status. GMC-10-R is active production with ROHS3 compliance. All electrical and mechanical parameters are identical.

Q: Are the secondary equivalent part numbers (0233010.MXP, BK/GMC-10-R, etc.) interchangeable with GMC-10-R?

A: Yes. All listed secondary equivalents maintain identical electrical and mechanical specifications. Selection is based on packaging format, supplier availability, and procurement requirements rather than technical performance differences.

Q: What packaging formats are available for 10 A 125 V AC/DC 5mm x 20mm glass cartridge fuses?

A: GMC-10-R is available in bulk packaging. Secondary equivalents (0233010.MXP, BK/GMC-10-R, BK1/GMC-10-R, 0232010.MX125P, 0233010.MXBP) may be available in alternative packaging configurations. Verify specific packaging requirements with supplier documentation.

Q: Is RoHS3 compliance required for my application?

A: RoHS3 compliance is mandatory for products sold in the European Union and for many industrial and commercial applications subject to environmental regulations. GMC-10-R and all secondary equivalents meet ROHS3 requirements. GMC-10A does not. For new designs or systems requiring regulatory compliance, select GMC-10-R or equivalent active production alternatives.

Q: Can I use a different current rating or voltage rating fuse as a substitute?

A: No. Fuse current rating and voltage rating are critical safety parameters. Substitution is limited to parts with identical 10 A current rating and 125 V AC voltage rating. Using incorrect ratings creates fire and electrical hazard risks.

Q: What does "medium blow" response time mean?

A: Medium blow indicates the fuse operates with standard response characteristics, clearing overcurrent conditions within a defined time window. This response time must match the original specification. Substitutes with fast-blow or slow-blow characteristics are not acceptable.
