Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GMA-15-R are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Current Rating: 15 A
• Voltage Rating (AC): 125 V
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 150 A
• Melting I²t: 950
• DC Cold Resistance: 0.004 Ohms

Mechanical Parameters (Must Match Exactly):

• Fuse Type: Cartridge, Glass
• Package / Case: 5mm x 20mm
• Mounting Type: Requires Holder

Compliance Parameters (Must Match or Exceed):

• Approval Agencies: CSA, PSE, UL
• RoHS Status: RoHS Compliant or higher

The substitute part BK/GMA-15-R meets all these criteria and is therefore electrically and mechanically interchangeable with the GMA-15-R.

Parameter Comparison

Engineering Selection Recommendations

Both GMA-15-R and BK/GMA-15-R are Active products manufactured by Eaton - Electronics Division and carry identical electrical and mechanical specifications. Selection between these parts may be based on the following factors:

Packaging Consideration: The GMA-15-R is supplied in standard packaging, while BK/GMA-15-R is supplied in bulk packaging. Bulk packaging may be appropriate for high-volume production environments.

Compliance Status: The BK/GMA-15-R carries ROHS3 Compliant status and includes REACH Unaffected designation, providing enhanced environmental compliance documentation compared to the standard RoHS Compliant status of the GMA-15-R.

Inventory Availability: The BK/GMA-15-R has higher current inventory (1372 pieces) compared to GMA-15-R (981 pieces), which may support supply chain continuity for high-volume requirements.

Regulatory Approvals: Both parts maintain CSA, PSE, and UL approvals, ensuring compliance with North American and international safety standards.

Frequently Asked Questions (FAQ)

Q: Are GMA-15-R and BK/GMA-15-R electrically interchangeable?

A: Yes. Both parts have identical current ratings (15 A), voltage ratings (125 V AC), response characteristics (Fast Blow), breaking capacity (150 A), and melting I²t values (950). They are direct electrical equivalents.

Q: Are these fuses mechanically interchangeable?

A: Yes. Both parts are glass cartridge fuses with identical 5mm x 20mm dimensions (0.205" Dia x 0.787" L) and require the same fuse holder for installation.

Q: What is the difference between GMA-15-R and BK/GMA-15-R?

A: The primary differences are packaging type (standard versus bulk) and RoHS compliance level (RoHS Compliant versus ROHS3 Compliant). All electrical and mechanical parameters are identical.

Q: Can I use BK/GMA-15-R as a direct replacement for GMA-15-R?

A: Yes. The BK/GMA-15-R meets all electrical, mechanical, and regulatory requirements for direct substitution in any application using GMA-15-R.

Q: What does "Requires Holder" mean?

A: This fuse type is a cartridge fuse that must be installed in a compatible 5mm x 20mm fuse holder. It is not a plug-type fuse and cannot be used without an appropriate holder assembly.

Q: Are both parts RoHS compliant?

A: Yes. GMA-15-R is RoHS Compliant, and BK/GMA-15-R is ROHS3 Compliant. Both meet RoHS requirements for hazardous substance restrictions.

Q: What approvals do these fuses carry?

A: Both GMA-15-R and BK/GMA-15-R carry CSA, PSE, and UL approvals, meeting North American and international safety certification standards.
