Equivalent & Substitute Parts for BK/GDA-63MA Ceramic Fuse

Part Overview

The BK/GDA-63MA is a 63 mA ceramic fuse cartridge rated for 250 V AC/DC operation in a 5mm x 20mm form factor. This fast-blow fuse is designed for applications requiring circuit protection with rapid response characteristics. The part is currently active in production and maintains inventory availability. Substitute parts are identified based on matching electrical specifications, mechanical dimensions, and functional performance parameters to ensure direct interchangeability in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/GDA-63MA is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Current Rating: 63 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)

All identified substitute parts meet these criteria. Variations in secondary parameters such as DC Cold Resistance, Melting I²t tolerance, and approval agency certifications do not affect substitution eligibility but may influence selection based on application-specific compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (BK/S501-63-R, S501-63-R, and 0216.063MXP) are electrically and mechanically equivalent to the BK/GDA-63MA based on critical fuse parameters. Selection between these options is determined by compliance and certification requirements:

BK/S501-63-R and S501-63-R (Eaton - Electronics Division): Both parts carry ROHS3 compliance and CSA/cULus certifications, providing enhanced regulatory alignment compared to the original BK/GDA-63MA. These parts are suitable for applications requiring RoHS3 compliance.

0216.063MXP (Littelfuse Inc.): This part offers the broadest certification coverage (CCC, CE, CSA, SEMKO, UR, VDE) and includes specified operating temperature range (-55°C ~ 125°C). ROHS3 compliance is confirmed. This part is suitable for applications with international regulatory requirements or extended temperature operation specifications.

Selection should be based on application-specific compliance mandates, certification requirements, and supply chain preferences. All parts maintain identical electrical performance and mechanical fit within standard 5mm x 20mm fuse holders.

Frequently Asked Questions (FAQ)

Q: Can BK/S501-63-R be used as a direct replacement for BK/GDA-63MA?

A: Yes. Both parts are 63 mA, 250 V AC ceramic cartridge fuses in 5mm x 20mm form factor with fast-blow response and 1.5 kA breaking capacity. Electrical and mechanical specifications are equivalent. The primary difference is RoHS3 compliance status of the substitute part.

Q: What is the difference between BK/S501-63-R and S501-63-R?

A: Both parts are from the Eaton S501 series with identical electrical and mechanical specifications. The primary distinction is packaging designation. Both are suitable substitutes for BK/GDA-63MA.

Q: Why does 0216.063MXP have different DC Cold Resistance (10.45 Ohms vs. 39 Ohms)?

A: DC Cold Resistance is a secondary parameter that does not affect fuse substitution eligibility. The critical parameters for substitution are current rating, voltage rating, package dimensions, response time, and breaking capacity, all of which match across all parts. The resistance difference reflects manufacturing design variation between Littelfuse and Eaton products but does not impact circuit protection function.

Q: Is 0216.063MXP suitable for applications requiring extended temperature operation?

A: The 0216.063MXP specifies an operating temperature range of -55°C ~ 125°C. The original BK/GDA-63MA and other Eaton substitutes do not provide specified operating temperature data. If extended temperature operation is required, 0216.063MXP provides documented temperature specifications.

Q: Which substitute part should be selected for RoHS3 compliance?

A: All three substitute parts (BK/S501-63-R, S501-63-R, and 0216.063MXP) are ROHS3 compliant. The original BK/GDA-63MA is RoHS non-compliant. Selection among the three compliant options depends on certification requirements and supply availability.

Q: Are all substitute parts compatible with existing 5mm x 20mm fuse holders?

A: Yes. All parts maintain identical mechanical dimensions (0.205" Dia x 0.787" L / 5.20mm x 20.00mm) and require standard fuse holders. No mechanical modification or holder replacement is necessary.

Q: What approval agencies certify each substitute part?

A: BK/S501-63-R and S501-63-R carry CCC, CSA, and cULus certifications. 0216.063MXP carries CCC, CE, CSA, SEMKO, UR, and VDE certifications. Selection should align with regional regulatory requirements for the target application.
