BK/GMC-800-R Equivalent & Substitute Parts

Part Overview

The BK/GMC-800-R is an 800 mA, 250 V AC glass cartridge fuse manufactured by Eaton - Electronics Division. This component is a medium-blow fuse in the 5mm x 20mm form factor, designed for applications requiring overcurrent protection in AC circuits. The part maintains Active product status with 1029 pieces in current inventory. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent functionality.

Substitute Part Grouping Explanation

Substitution of the BK/GMC-800-R is determined by strict equivalence across the following critical parameters:

Current Rating: 800 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)

Mounting Type: Requires Holder (exact match required)

The substitute part 0034.2515 from SCHURTER Inc. meets all mandatory equivalence criteria. Additional parameters including breaking capacity, melting I²t, and DC voltage rating differ between the main part and substitute but do not disqualify substitution when AC 250 V operation is the primary design requirement.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - BK/GMC-800-R (Eaton - Electronics Division):

The BK/GMC-800-R maintains Active product status with established inventory availability (1029 pieces). This part carries CSA, KC-MARK, and UL approval certifications. DC cold resistance is specified at 0.18 Ohms. Selection of this part is appropriate for applications where Eaton component qualification is required or where the specified breaking capacity of 35 A at rated voltage is the design requirement.

Substitute Part - 0034.2515 (SCHURTER Inc.):

The 0034.2515 is functionally equivalent for AC 250 V, 800 mA applications in the 5mm x 20mm cartridge form factor. This part provides higher breaking capacity (80 A) and higher melting I²t (1.68 versus 0.85), indicating enhanced performance characteristics. The substitute includes DC voltage rating of 125 V, extending application flexibility. ROHS3 compliance is maintained. Current inventory availability is 1710 pieces. Selection of this part is appropriate when SCHURTER sourcing is acceptable and when the enhanced breaking capacity provides system-level benefits.

Both parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8536.10.0020.

Frequently Asked Questions (FAQ)

Q: Can the 0034.2515 directly replace the BK/GMC-800-R in existing designs?

A: Yes, for applications operating at 250 V AC with 800 mA current requirements. Both parts are identical in current rating, voltage rating (AC), fuse type, package dimensions, response time, and mounting configuration. Physical installation in existing fuse holders is compatible.

Q: What is the significance of the different breaking capacity values (35 A versus 80 A)?

A: Breaking capacity defines the maximum fault current the fuse can safely interrupt without rupturing the fuse element or holder. The 0034.2515 with 80 A breaking capacity provides higher fault current handling. Selection depends on the maximum prospective short-circuit current in the application circuit.

Q: Does the 0034.2515 DC voltage rating of 125 V affect AC-only applications?

A: No. For AC-only applications, the DC voltage rating is not a limiting factor. The AC voltage rating of 250 V is the controlling specification. The DC rating on the substitute part represents additional capability that does not impact AC circuit performance.

Q: Are both parts suitable for the same operating temperature range?

A: The BK/GMC-800-R does not specify an operating temperature range in the provided data. The 0034.2515 specifies -40°C to 85°C. For applications with temperature requirements, the SCHURTER part provides explicit temperature specification.

Q: What is the difference in melting I²t between these parts?

A: Melting I²t (0.85 for BK/GMC-800-R versus 1.68 for 0034.2515) indicates the thermal energy required to melt the fuse element. The higher value on the substitute part indicates a slightly slower thermal response. Both are classified as medium-blow fuses. Application-specific thermal coordination requirements determine if this difference is significant.

Q: Are approval certifications equivalent between the two parts?

A: The BK/GMC-800-R carries CSA, KC-MARK, and UL certifications. The 0034.2515 does not list approval agencies in the provided data. For applications requiring specific certification marks, the Eaton part maintains documented compliance.

Q: Can these parts be used interchangeably in inventory management?

A: Yes, for applications where the design permits either manufacturer. Both parts share identical electrical and mechanical specifications for AC 250 V, 800 mA operation in 5mm x 20mm holders. Inventory consolidation is possible when application requirements allow either part.
