GDA-315MA Equivalent & Substitute Parts

Part Overview

The GDA-315MA is a ceramic fuse cartridge manufactured by Eaton - Electronics Division, rated for 315 mA at 250 V AC with a fast-blow response characteristic. This component is a 5mm x 20mm form-factor fuse requiring a dedicated holder for installation. The part maintains active product status with 980 pieces in current inventory stock.

Equivalent substitute parts are identified when components share identical electrical ratings, mechanical dimensions, response characteristics, and approval certifications. Substitute parts enable procurement flexibility, inventory optimization, and supply chain continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GDA-315MA is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Current Rating: 315 mA (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 critical parameters. Variations in secondary parameters such as DC cold resistance, operating temperature range, and approval agency certifications do not disqualify substitution eligibility when primary electrical and mechanical specifications align.

Engineering Selection Recommendations

GDA-315MA (Eaton - Electronics Division)

The GDA-315MA serves as the primary reference part with active product status and established approval certifications including CCC, CSA, IMQ, SEMKO, and UR. This part is suitable for applications requiring Eaton component qualification or when existing supply agreements specify this manufacturer.

0216.315TXP (Littelfuse Inc.)

The 0216.315TXP is a direct parametric equivalent with identical electrical ratings and mechanical dimensions. This substitute provides expanded approval agency coverage including CE and VDE certifications in addition to CCC, CSA, SEMKO, and UR. The component includes RoHS3 compliance and REACH unaffected status. Operating temperature range is specified as -55°C to 125°C. This part is suitable for applications requiring extended environmental specifications or additional regulatory certifications.

FCD-315MA (OptiFuse)

The FCD-315MA is a direct parametric equivalent with identical electrical ratings and mechanical dimensions. This substitute explicitly specifies 250 V DC voltage rating in addition to 250 V AC, providing expanded application scope for dual-voltage circuits. The component includes RoHS3 compliance and IEC 60127 approval. Operating temperature range is specified as -55°C to 125°C. This part is suitable for applications requiring DC voltage capability or IEC 60127 certification.

All three parts maintain active product status and are available in current inventory. Selection between substitutes is determined by specific application requirements regarding voltage type (AC only versus AC/DC), regulatory certifications, and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the 0216.315TXP replace the GDA-315MA in all applications?

A: The 0216.315TXP is a parametric equivalent with matching current rating (315 mA), AC voltage rating (250 V), fuse type (ceramic cartridge), package dimensions (5mm x 20mm), response time (fast blow), and breaking capacity (1.5 kA). Physical installation compatibility is identical as both require a 5mm x 20mm fuse holder. Substitution is valid for AC applications. Applications requiring DC voltage operation should reference the FCD-315MA specification.

Q: What is the difference between the GDA-315MA and FCD-315MA?

A: Both parts share identical AC electrical ratings (315 mA, 250 V), ceramic cartridge construction, 5mm x 20mm dimensions, and fast-blow response. The FCD-315MA explicitly specifies 250 V DC rating, whereas the GDA-315MA does not specify DC voltage capability. The FCD-315MA is suitable for circuits operating at both AC and DC voltages up to 250 V. The GDA-315MA is suitable for AC applications. Both parts are mechanically and electrically interchangeable for AC-only circuits.

Q: Are all three parts physically compatible with the same fuse holder?

A: Yes. All three parts share identical package dimensions of 5mm x 20mm and require a dedicated fuse holder for installation. Any 5mm x 20mm ceramic fuse holder will accommodate all three parts without modification.

Q: What approval certifications should I consider when selecting a substitute?

A: The GDA-315MA carries CCC, CSA, IMQ, SEMKO, and UR approvals. The 0216.315TXP carries CCC, CE, CSA, SEMKO, UR, and VDE approvals. The FCD-315MA carries IEC 60127 approval. Selection depends on the regulatory requirements of the target application and geographic market. Applications requiring CE or VDE certification should use the 0216.315TXP. Applications requiring IEC 60127 certification should use the FCD-315MA.

Q: Does the melting I²t value affect substitution eligibility?

A: The GDA-315MA and 0216.315TXP both specify melting I²t of 0.01, while the FCD-315MA specifies 0.0142. All three parts are parametric equivalents with identical current ratings, voltage ratings, and breaking capacity. The melting I²t variation reflects minor differences in ceramic composition and thermal characteristics between manufacturers but does not disqualify substitution when all primary electrical and mechanical parameters match.

Q: What is the significance of DC cold resistance differences?

A: The GDA-315MA specifies 3.3 Ohms DC cold resistance, while the 0216.315TXP specifies 1.85 Ohms. DC cold resistance affects resistive heating during normal operation but does not impact fuse breaking capacity or response time at rated current. Both values are within acceptable ranges for ceramic fuse cartridges. This parameter difference does not affect substitution eligibility for standard applications.

Q: Are there environmental operating temperature considerations for substitution?

A: The GDA-315MA does not specify an operating temperature range. The 0216.315TXP and FCD-315MA both specify -55°C to 125°C operating range. For applications requiring operation outside standard ambient conditions, the 0216.315TXP or FCD-315MA provide explicit temperature specifications. For standard indoor applications, all three parts are suitable.
