Equivalent & Substitute Parts for GDA-3.15A Ceramic Fuse

Part Overview

The GDA-3.15A is a ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated at 3.15 A, 250 V AC/DC with fast-blow response characteristics. This component is designed for use in 5mm x 20mm fuse holders and requires a separate holder for installation. The part maintains active product status with 814 units in current inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across manufacturers. Alternative sources become necessary for supply chain continuity, extended lead times, or regional availability requirements while preserving circuit protection performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Current Rating: 3.15 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitute parts meet these mandatory parameters. Variations in secondary parameters such as Melting I²t, DC Cold Resistance, Operating Temperature range, and approval agency certifications do not disqualify substitution eligibility when primary electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

Eaton GDA and S501 Series (BK/GDA-3.15A, BK/S501-3.15-R, BK1/S501-3.15-R, S501-3.15-R): These parts are manufactured by Eaton - Electronics Division and maintain identical electrical and mechanical specifications to the primary GDA-3.15A part. All variants carry active product status. Selection among these options is based on inventory availability and regional certification requirements. BK1/S501-3.15-R offers the highest inventory level at 2016 units.

SCHURTER 0001.1009: This part is manufactured by SCHURTER Inc. under the SP 5x20 series and meets all mandatory substitution parameters. It carries active product status with 4321 units in inventory. Operating temperature range is specified as -55°C to 125°C. Approval agencies include CCC, cURus, KC, PSE/JET, and VDE.

Littelfuse 02163.15MXP: This part is manufactured by Littelfuse Inc. under the 216 series and meets all mandatory substitution parameters. It carries active product status with the highest inventory availability at 16650 units. Operating temperature range is specified as -55°C to 125°C. Approval agencies include CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE.

OptiFuse FCD-3.15A: This part is manufactured by OptiFuse under the FCD series and meets all mandatory substitution parameters. It carries active product status with 872 units in inventory. This part specifies both 250 V AC and 250 V DC voltage ratings. Operating temperature range is specified as -55°C to 125°C. Approval basis is IEC 60127.

Frequently Asked Questions (FAQ)

Q: What determines if a fuse can substitute for the GDA-3.15A?

A: Substitution requires exact equivalence in seven critical parameters: Current Rating (3.15 A), Voltage Rating - AC (250 V), Fuse Type (Cartridge, Ceramic), Package / Case (5mm x 20mm), Response Time (Fast Blow), Breaking Capacity @ Rated Voltage (1.5 kA), and Mounting Type (Requires Holder). All identified substitute parts meet these requirements.

Q: Are there differences in Melting I²t values among the substitutes?

A: Yes. The GDA-3.15A and Eaton S501 series specify 8.1, while SCHURTER 0001.1009 specifies 6.78, Littelfuse 02163.15MXP specifies 6.7, and OptiFuse FCD-3.15A specifies 4.271. These variations do not affect substitution eligibility as Melting I²t is not a mandatory equivalence parameter for this product category.

Q: Do all substitute parts fit in the same 5mm x 20mm holder?

A: Yes. All substitute parts maintain the 5mm x 20mm package specification and are designed for use in standard 5mm x 20mm fuse holders. Physical form factor compatibility is guaranteed.

Q: Which substitute offers the best inventory availability?

A: Littelfuse 02163.15MXP offers the highest inventory level at 16650 units, followed by SCHURTER 0001.1009 at 4321 units.

Q: Are there regional certification differences I should consider?

A: Yes. Eaton parts carry certifications including CCC, CSA, IMQ, SEMKO, and UR/UL variants. SCHURTER 0001.1009 includes CCC, cURus, KC, PSE/JET, and VDE. Littelfuse 02163.15MXP includes CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE. OptiFuse FCD-3.15A references IEC 60127. Selection should align with your regional compliance requirements.

Q: What is the difference between GDA-3.15A and BK/GDA-3.15A?

A: Both are manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications. The "BK" designation indicates a specific packaging or distribution variant. Both are active products suitable for direct substitution.

Q: Can I use FCD-3.15A if my circuit requires DC voltage rating?

A: FCD-3.15A explicitly specifies both 250 V AC and 250 V DC ratings, making it suitable for applications requiring DC voltage specification. Other parts specify AC rating only.
