Substitute Part Grouping Explanation

Substitute parts for the GMC-80-R are determined by strict equivalence across the following critical parameters:

Current Rating: 80 mA (exact match required)

Voltage Rating - AC: 250 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: 35 A (exact match required)

Melting I²t: 0.005 (exact match required)

Approval Agencies: CSA, KC-MARK, UL (exact match required)

RoHS Status: ROHS3 Compliant (exact match required)

The substitute part BK/GMC-80-R meets all critical electrical and mechanical parameters, making it a direct equivalent for circuit protection applications requiring identical performance characteristics and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The BK/GMC-80-R is a direct equivalent substitute for the GMC-80-R based on complete parameter alignment across all electrical, mechanical, and regulatory specifications. Both components are manufactured by Eaton - Electronics Division, carry identical current and voltage ratings, and maintain the same 5mm x 20mm physical form factor. Both parts hold active product status and comply with CSA, KC-MARK, and UL approval standards, as well as ROHS3 compliance requirements.

Selection between GMC-80-R and BK/GMC-80-R should be based on inventory availability and supply chain requirements. The GMC-80-R currently has 1054 units in stock, while the BK/GMC-80-R has 679 units available. Both parts are suitable for direct substitution in circuit protection applications without design modification or performance compromise.

Frequently Asked Questions (FAQ)

Q: Can BK/GMC-80-R be used as a direct replacement for GMC-80-R?

A: Yes. The BK/GMC-80-R is a direct equivalent substitute. All electrical parameters (80 mA current rating, 250 V AC voltage rating, 35 A breaking capacity, 0.005 melting I²t), mechanical specifications (5mm x 20mm package), response characteristics (medium blow), and regulatory certifications (CSA, KC-MARK, UL, ROHS3) are identical.

Q: Are there any compatibility issues when substituting these parts?

A: No compatibility issues exist. Both parts require the same holder type and are mechanically and electrically interchangeable. The identical 5mm x 20mm form factor ensures proper fit in existing fuse holders and circuit protection applications.

Q: What is the difference between GMC-80-R and BK/GMC-80-R?

A: The parts are electrically and mechanically identical. The designation difference reflects internal Eaton - Electronics Division part numbering conventions. Both are from the GMC series and carry identical specifications.

Q: Which part should I select based on availability?

A: Selection should be based on supply chain requirements and inventory status. GMC-80-R has 1054 units in stock, while BK/GMC-80-R has 679 units available. Both are active products with equivalent performance.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both GMC-80-R and BK/GMC-80-R hold identical approvals from CSA, KC-MARK, and UL, and both comply with ROHS3 requirements.

Q: What is the melting I²t specification and why is it important?

A: The melting I²t value of 0.005 defines the thermal energy required to melt the fuse element. This parameter must match exactly for proper circuit protection performance. Both parts share this identical specification.

Q: Can these fuses be used without a holder?

A: No. Both GMC-80-R and BK/GMC-80-R require a holder for installation and operation. The mounting type for both parts is specified as "Requires Holder."
