GMA-6A Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The GMA-6A is a 6 A, 125 V AC/DC glass cartridge fuse manufactured by Eaton - Electronics Division. This fast-blow fuse is designed for use in 5mm x 20mm fuse holders and provides circuit protection in electrical systems requiring rated breaking capacity of 10 kA. The part is active in production and widely stocked. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GMA-6A are qualified based on the following critical parameters that must match or remain compatible:

• Current Rating: 6 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required for mechanical fit in holder)
• Breaking Capacity @ Rated Voltage: 10 kA (exact match required for circuit protection integrity)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed below meet these critical parameters. Secondary parameters such as DC cold resistance, melting I²t, operating temperature range, and approval agencies may vary within acceptable engineering tolerances but do not affect functional substitutability for the specified application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status. Selection among equivalent parts should be based on the following factors:

Eaton - Electronics Division Parts (GMA-6A, GMA-6-R, BK/GMA-6-R): These parts maintain consistency within the Eaton product family. GMA-6-R and BK/GMA-6-R provide documented electrical characteristics and comprehensive approval agency certifications (CSA, PSE, UL). BK/GMA-6-R carries ROHS3 compliance designation, indicating alignment with current regulatory requirements.

Littelfuse Inc. Parts (0235006.HXP, 0235006.MXP, 0235006.VXP): These parts from the 235 series provide equivalent electrical performance with extended operating temperature range (-55°C to 125°C) and broader approval agency coverage including CE and KC certifications. All three variants carry ROHS3 compliance and REACH Unaffected status. The variants differ in approval agency scope: 0235006.HXP and 0235006.MXP include KC approval, while 0235006.VXP includes K-MARK approval.

Eaton - Bussmann Electrical Division Part (BP/GMA-6A): This part maintains the GMA series designation and RoHS compliance but provides limited documented electrical characteristics and approval agency information.

All parts are mechanically and electrically interchangeable within the specified 5mm x 20mm fuse holder application.

Frequently Asked Questions (FAQ)

Q: Can GMA-6A be directly replaced with GMA-6-R?

A: Yes. Both parts share identical electrical specifications: 6 A current rating, 125 V AC voltage rating, fast-blow response, 10 kA breaking capacity, and 5mm x 20mm package dimensions. GMA-6-R provides additional documented electrical characteristics and approval certifications.

Q: What is the difference between Littelfuse 0235006.HXP, 0235006.MXP, and 0235006.VXP?

A: All three parts are electrically and mechanically equivalent with identical current rating, voltage rating, response time, and package dimensions. The primary differences are approval agency certifications: 0235006.HXP and 0235006.MXP include KC approval, while 0235006.VXP includes K-MARK approval. Selection depends on regional regulatory requirements.

Q: Are there operating temperature differences between substitute parts?

A: Yes. Eaton parts (GMA-6A, GMA-6-R, BK/GMA-6-R) do not specify operating temperature range. Littelfuse parts (0235006.HXP, 0235006.MXP, 0235006.VXP) specify -55°C to 125°C operating temperature range. For applications requiring extended temperature operation, Littelfuse variants are appropriate.

Q: Do all substitute parts fit in the same fuse holder?

A: Yes. All parts conform to 5mm x 20mm package dimensions and require the same holder type. Mechanical fit is identical across all substitute parts.

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: ROHS3 represents compliance with the current Restriction of Hazardous Substances Directive (RoHS 3 / 2011/65/EU as amended). Parts marked RoHS Compliant may reference earlier RoHS versions. For new designs and procurement, ROHS3 compliant parts (BK/GMA-6-R and all Littelfuse variants) align with current regulatory standards.

Q: Can BP/GMA-6A be used as a substitute for GMA-6A?

A: Yes. BP/GMA-6A meets all critical electrical and mechanical parameters: 6 A current rating, 125 V AC voltage rating, fast-blow response, 5mm x 20mm package, and RoHS compliance. However, documented electrical characteristics and approval agency certifications are not provided for this part number.

Q: Which substitute part has the lowest DC cold resistance?

A: Littelfuse parts (0235006.HXP, 0235006.MXP, 0235006.VXP) have DC cold resistance of 0.0148 Ohms, compared to 0.017 Ohms for Eaton GMA-6-R and BK/GMA-6-R. This difference does not affect functional substitutability.

Q: Are all substitute parts in active production?

A: Yes. All substitute parts listed carry Active product status, indicating current manufacturing and availability.
