BK/GDB-V-63MA Equivalent & Substitute Parts

Part Overview

The BK/GDB-V-63MA is a 63 mA, 250 V AC/DC fast-blow glass cartridge fuse with a 5mm x 20mm axial through-hole package manufactured by Eaton - Electronics Division. This component is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to maintain circuit protection functionality in applications where the original GDB series is no longer available or when design flexibility is required for procurement optimization.

Substitute Part Grouping Explanation

Substitute parts for the BK/GDB-V-63MA are classified based on strict electrical and mechanical parameter alignment:

Direct Manufacturer Substitutes (Eaton - Electronics Division):

• BK/S500-V-63-R and BK/GMA-V-63-R are Eaton products sharing identical electrical specifications: 63 mA current rating, 250 V AC voltage rating, fast-blow response, 5mm x 20mm package, and 35 A breaking capacity. These parts maintain the same functional performance within the original design envelope.

Cross-Manufacturer Equivalent (Littelfuse Inc.):

• 0217.063MXEP is a Littelfuse product meeting the same electrical parameters: 63 mA, 250 V AC, fast-blow response, and 35 A breaking capacity. Physical dimensions vary slightly (6.00mm x 22.50mm versus 5.54mm x 21.10mm), requiring mechanical fit verification in the target application.

Substitution eligibility is determined exclusively by matching: current rating, voltage rating, response time classification, breaking capacity, and mechanical compatibility with the through-hole mounting footprint.

Parameter Comparison

Engineering Selection Recommendations

BK/S500-V-63-R (Eaton - Electronics Division): This substitute maintains active product status and is the primary choice for direct replacement within Eaton's portfolio. Electrical parameters are identical to the BK/GDB-V-63MA. RoHS compliance is confirmed. This part is suitable for applications requiring Eaton component continuity.

BK/GMA-V-63-R (Eaton - Electronics Division): This substitute is active and carries multiple approval certifications (CSA, PSE, UL), providing broader regulatory coverage than the original GDB series. Electrical parameters match the main part. RoHS compliance is confirmed. The lower melting I²t value (0.00024 versus 0.00057) indicates faster thermal response characteristics.

0217.063MXEP (Littelfuse Inc.): This cross-manufacturer equivalent is active and carries the broadest approval agency coverage (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE). Electrical parameters align with the main part. ROHS3 compliance and REACH unaffected status are confirmed. Physical dimensions differ slightly (6.00mm x 22.50mm); mechanical fit within the target PCB or holder must be verified. The melting I²t value (0.00056) closely matches the original part.

Frequently Asked Questions (FAQ)

Q: Can BK/S500-V-63-R be used as a direct replacement for BK/GDB-V-63MA?

A: Yes. Both parts share identical electrical specifications: 63 mA current rating, 250 V AC voltage rating, fast-blow response time, 35 A breaking capacity, and 5mm x 20mm through-hole package. The BK/S500-V-63-R is active product status, addressing the obsolescence of the GDB series.

Q: What is the difference between BK/GMA-V-63-R and BK/S500-V-63-R?

A: Both are Eaton products with matching electrical parameters. The BK/GMA-V-63-R carries additional approval certifications (CSA, PSE, UL) and exhibits a lower melting I²t value (0.00024 versus 0.00057), resulting in faster thermal response. Selection depends on regulatory requirements and thermal response characteristics needed for the application.

Q: Can the Littelfuse 0217.063MXEP replace the Eaton BK/GDB-V-63MA?

A: Electrical parameters are equivalent. However, the 0217.063MXEP has slightly larger physical dimensions (6.00mm x 22.50mm versus 5.54mm x 21.10mm). Mechanical compatibility with the PCB footprint or fuse holder must be confirmed before substitution.

Q: Why do the DC cold resistance values differ among these parts?

A: DC cold resistance variation is a manufacturing characteristic within the same functional class. All parts meet the 63 mA, 250 V, fast-blow specification. Resistance differences do not affect circuit protection performance at rated operating conditions.

Q: Which substitute part has the best regulatory coverage?

A: The Littelfuse 0217.063MXEP carries the most comprehensive approval agency certifications: CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. This part is suitable for applications requiring broad international regulatory compliance.

Q: Is the BK/GMA-V-63-R suitable for high-speed circuit protection applications?

A: The BK/GMA-V-63-R has a lower melting I²t value (0.00024) compared to the original BK/GDB-V-63MA (0.00057), indicating faster thermal response. Applications requiring rapid fault isolation may benefit from this characteristic.
