GMA-10A Equivalent & Substitute Parts

Part Overview

The GMA-10A is a 10 A 125 V AC/DC glass fuse cartridge manufactured by Eaton - Electronics Division. This component requires a fuse holder for installation and operates as a fast-blow protective device in electrical circuits. The part is currently in active production with 826 pieces available in new original stock. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate alternative manufacturer stock.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GMA-10A is determined by strict equivalence across the following 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: Fast Blow (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Breaking Capacity @ Rated Voltage: 200 A (exact match required)

The GMA-10-R meets all substitution criteria and is classified as a direct equivalent. Both parts are manufactured by Eaton - Electronics Division within the GMA series and share identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The GMA-10-R is a direct functional equivalent to the GMA-10A. Both parts are manufactured by Eaton - Electronics Division and maintain identical electrical and mechanical specifications across all critical parameters including current rating, voltage rating, fuse type, package dimensions, and response characteristics.

The GMA-10-R carries active product status and holds certifications from CSA, PSE, and UL approval agencies. The part is RoHS compliant and currently maintains 860 pieces in new original stock inventory.

Selection between GMA-10A and GMA-10-R is based on inventory availability and sourcing requirements. Both parts are suitable for direct substitution in applications requiring a 10 A 125 V AC/DC fast-blow glass cartridge fuse in a 5mm x 20mm package.

Frequently Asked Questions (FAQ)

Q: Can the GMA-10-R be used as a direct replacement for the GMA-10A?

A: Yes. The GMA-10-R meets all electrical and mechanical specifications of the GMA-10A, including current rating, voltage rating, fuse type, package dimensions, response time, and breaking capacity.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution requires exact equivalence in current rating (10 A), voltage rating (125 V AC), fuse type (Cartridge, Glass), package dimensions (5mm x 20mm), response time (Fast Blow), and breaking capacity (200 A @ rated voltage).

Q: Do both parts require the same holder for installation?

A: Yes. Both the GMA-10A and GMA-10-R require a fuse holder for installation and share identical 5mm x 20mm package dimensions.

Q: What certifications does the GMA-10-R carry?

A: The GMA-10-R holds approvals from CSA, PSE, and UL agencies and is RoHS compliant.

Q: Are there any differences in electrical performance between the two parts?

A: Both parts share identical electrical specifications. The GMA-10-R provides additional documented parameters including DC cold resistance (0.006 Ohms) and melting I²t (280), which are compatible with the GMA-10A application requirements.

Q: What is the current inventory status for substitute parts?

A: The GMA-10-R currently maintains 860 pieces in new original stock, compared to 826 pieces for the GMA-10A.
