Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GMA-10-R 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)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Breaking Capacity @ Rated Voltage: 200 A (exact match required)
• Melting I²t: 280 (exact match required)
• DC Cold Resistance: 0.006 Ohms (exact match required)
• Approval Agencies: CSA, PSE, UL (exact match required)

The identified substitute part BK/GMA-10-R meets all electrical and mechanical parameters. The primary distinction is packaging format: BK/GMA-10-R is supplied in Bulk packaging, whereas GMA-10-R uses standard packaging. Both parts are manufactured by Eaton - Electronics Division and belong to the GMA series.

Parameter Comparison

Engineering Selection Recommendations

Both GMA-10-R and BK/GMA-10-R are Active products manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and inventory requirements:

GMA-10-R is appropriate for standard procurement workflows with 860 units currently available.

BK/GMA-10-R is appropriate for bulk procurement applications with significantly higher inventory availability (4743 units). This part carries ROHS3 Compliant status, providing enhanced regulatory alignment for applications requiring the latest RoHS revision compliance.

Both parts carry CSA, PSE, and UL approvals, confirming suitability for regulated applications. Both are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can BK/GMA-10-R be used as a direct replacement for GMA-10-R in circuit protection applications?

A: Yes. Both parts are electrically and mechanically identical. They share the same 10 A current rating, 125 V AC voltage rating, 5mm x 20mm physical dimensions, 200 A breaking capacity, and 0.006 Ohms DC cold resistance. Both require a fuse holder for installation and provide fast-blow response characteristics.

Q: What is the difference between GMA-10-R and BK/GMA-10-R?

A: The primary difference is packaging format. GMA-10-R uses standard packaging, while BK/GMA-10-R is supplied in Bulk packaging. Additionally, BK/GMA-10-R carries ROHS3 Compliant status compared to RoHS Compliant for GMA-10-R. Inventory levels also differ: 860 units for GMA-10-R versus 4743 units for BK/GMA-10-R.

Q: Are both parts suitable for 125 V AC applications?

A: Yes. Both GMA-10-R and BK/GMA-10-R are rated for 125 V AC operation and carry identical voltage specifications.

Q: Do both parts require a fuse holder?

A: Yes. Both parts are cartridge-type fuses with 5mm x 20mm dimensions and require installation in a compatible fuse holder. Neither part is designed for direct circuit mounting.

Q: What regulatory approvals apply to both parts?

A: Both parts carry CSA, PSE, and UL approvals, confirming compliance with North American and international safety standards for overcurrent protection devices.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the existing design uses a 5mm x 20mm fuse holder. The electrical characteristics, physical dimensions, and approval certifications are identical between both parts.
