GDA-63MA Equivalent & Substitute Parts

Part Overview

The GDA-63MA is a ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated for 63 mA at 250 V AC/DC with a 5mm x 20mm form factor. This fast-blow fuse is designed for applications requiring overcurrent protection in low-voltage circuits and requires a compatible fuse holder for installation. The part is currently active in production. Substitute parts are identified based on matching electrical specifications, mechanical dimensions, and functional performance characteristics to ensure direct interchangeability in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GDA-63MA is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Current Rating: 63 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 1.5 kA at rated voltage (exact match required)

Mechanical Equivalence Criteria:

• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the GDA-63MA in applications where the fuse holder is compatible with the 5mm x 20mm form factor.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the GDA-63MA based on matching current rating, voltage rating, response time, breaking capacity, and 5mm x 20mm form factor.

Eaton S501 Series (BK/S501-63-R, S501-63-R): These parts maintain identical electrical specifications and DC cold resistance to the GDA-63MA. Both are ROHS3 compliant and carry CSA and cULus certifications in addition to CCC approval. The BK/S501-63-R variant includes REACH Unaffected status. These options are suitable for applications requiring regulatory compliance upgrades from the original GDA-63MA.

Littelfuse 216 Series (0216.063HXP, 0216.063MXP): These parts meet all electrical and mechanical equivalence criteria with slightly higher melting I²t values (0.00054 versus 0.0005). Both are ROHS3 compliant with expanded approval agency certifications including CE, VDE, and SEMKO. Operating temperature range is specified as -55°C to 125°C. DC cold resistance is lower at 10.45 Ohms compared to 39 Ohms in the Eaton variants. These options provide broader international certification coverage and defined temperature performance.

Selection between substitute parts should be based on specific application requirements regarding regulatory compliance, certification scope, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the GDA-63MA be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts (BK/S501-63-R, S501-63-R, 0216.063HXP, 0216.063MXP) are electrically and mechanically equivalent to the GDA-63MA. They share identical current rating (63 mA), voltage rating (250 V AC), response time (Fast Blow), breaking capacity (1.5 kA), and form factor (5mm x 20mm). Direct substitution is supported in applications using compatible 5mm x 20mm fuse holders.

Q: What is the significance of the different DC cold resistance values?

A: DC cold resistance affects the voltage drop across the fuse during normal operation. The GDA-63MA and Eaton S501 variants have 39 Ohms resistance, while Littelfuse 216 series parts have 10.45 Ohms. Lower resistance results in reduced voltage drop and heat generation during normal circuit operation. Selection should consider the specific circuit design and thermal management requirements.

Q: Are there differences in approval agencies between the main part and substitutes?

A: Yes. The GDA-63MA carries CCC, SEMKO, and UR approvals. The Eaton S501 variants add CSA and cULus certifications. The Littelfuse 216 series includes CE and VDE certifications in addition to the others. Applications requiring specific regional certifications should select the substitute part with appropriate approval agency coverage.

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 BK/S501-63-R includes REACH Unaffected status documentation. Selection between these variants depends on whether REACH compliance documentation is required for the application.

Q: Does the GDA-63MA have RoHS compliance?

A: The GDA-63MA is RoHS non-compliant. All substitute parts (BK/S501-63-R, S501-63-R, 0216.063HXP, 0216.063MXP) are ROHS3 compliant. Applications requiring RoHS compliance must use one of the substitute parts.

Q: What is the operating temperature range for these fuses?

A: The GDA-63MA and Eaton S501 variants do not specify an operating temperature range. The Littelfuse 216 series (0216.063HXP, 0216.063MXP) specifies -55°C to 125°C. Applications with defined temperature requirements should reference the Littelfuse variants or confirm temperature suitability with the Eaton manufacturer for the GDA-63MA and S501 series.

Q: Are all these fuses suitable for both AC and DC applications?

A: Yes. All parts are rated for 250 V AC/DC operation. The 63 mA current rating applies to both AC and DC circuits.

Q: What does "Requires Holder" mean for the mounting type?

A: These are cartridge fuses that must be installed in a compatible fuse holder. The 5mm x 20mm dimensions specify the holder cavity size. The fuse cannot be used without a proper holder assembly.
