Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GMA-600-R are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Matching Parameters:

• Current Rating: 600 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Package Dimensions: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitute parts meet these critical parameters. Secondary parameters such as breaking capacity, melting I²t, DC cold resistance, and operating temperature range may vary within acceptable engineering tolerances for the application category. Approval agency certifications and RoHS compliance status are documented for each substitute to support procurement and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Substitutes (Eaton - Electronics Division):

BK/GMA-600-R is a direct equivalent from the same manufacturer with identical electrical and mechanical specifications. This part carries ROHS3 Compliant status and maintains all original approval certifications (CSA, PSE, UL). Selection of this substitute eliminates any cross-manufacturer compatibility considerations.

Cross-Manufacturer Substitutes (Littelfuse Inc.):

0235.600HXP and 0235.600MXP are functionally equivalent parts from Littelfuse Inc., Series 235. Both parts match all critical electrical parameters and mechanical dimensions. These substitutes provide expanded approval agency coverage (CE, CSA, KC, UL) and documented operating temperature range (-55°C ~ 125°C). The melting I²t value (0.112) differs from the GMA-600-R (0.32), reflecting different thermal response characteristics within the fast-blow classification. DC cold resistance is slightly elevated at 0.3195 Ohms compared to 0.256 Ohms in the original part.

Parametric Equivalent (OptiFuse):

FSC-600MA from OptiFuse meets all critical electrical and mechanical parameters. This part features an elevated breaking capacity of 100A compared to 35A in the GMA-600-R, providing enhanced fault current handling capability. Operating temperature range is -55°C ~ 90°C. DC cold resistance is lower at 0.1224 Ohms. Approval certifications include cULus and UL 248. HTSUS classification differs (8535.10.0040 vs. 8536.10.0020).

All substitute parts maintain Active product status and RoHS3 compliance, supporting current procurement and environmental regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can BK/GMA-600-R be used as a direct replacement for GMA-600-R?

A: Yes. BK/GMA-600-R is manufactured by Eaton - Electronics Division and shares identical electrical ratings (600 mA, 250 V AC), fuse type (cartridge, glass), response time (fast blow), and mechanical dimensions (5mm x 20mm). Both parts require a compatible fuse holder and carry equivalent approval certifications.

Q: What is the difference between the Littelfuse 0235.600HXP and 0235.600MXP substitutes?

A: Both parts are functionally equivalent with matching current rating, voltage rating, package dimensions, and response time. The part number suffix differentiates product variants within the Littelfuse 235 series. Both carry identical electrical specifications and approval certifications (CE, CSA, KC, UL).

Q: How does the FSC-600MA breaking capacity of 100A compare to the GMA-600-R breaking capacity of 35A?

A: The FSC-600MA provides higher breaking capacity at rated voltage, indicating enhanced capability to safely interrupt higher fault currents. Both parts are rated for 600 mA continuous current and 250 V AC operation. The increased breaking capacity does not affect normal circuit operation but provides additional safety margin in fault conditions.

Q: Are all substitute parts compatible with existing GMA-600-R fuse holders?

A: Yes. All substitute parts share the identical 5mm x 20mm mechanical form factor and require the same holder type. Physical installation compatibility is confirmed across all listed substitutes.

Q: What approval certifications should I verify for my specific application?

A: The GMA-600-R carries CSA, PSE, and UL certifications. Littelfuse substitutes (0235.600HXP, 0235.600MXP) provide expanded coverage with CE, CSA, KC, and UL certifications. FSC-600MA carries cULus and UL 248 certifications. Verify that the selected substitute meets the approval requirements specified in your application documentation.

Q: Does operating temperature range affect substitute selection?

A: Operating temperature range is specified for Littelfuse (-55°C ~ 125°C) and OptiFuse (-55°C ~ 90°C) substitutes but not documented for the GMA-600-R. If your application operates outside standard ambient conditions, confirm that the selected substitute's temperature range accommodates your thermal environment.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes carry ROHS3 Compliant status, meeting current environmental and regulatory requirements for electronic component procurement.
