GDA-250MA Equivalent & Substitute Parts Reference

Part Overview

The GDA-250MA is a ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated for 250 mA at 250 V AC/DC with fast-blow response characteristics. This component requires a fuse holder for installation and is designed for circuit protection applications requiring 5mm x 20mm form factor. The part maintains active product status with 748 units in current inventory. Substitute parts are identified based on matching electrical ratings, mechanical dimensions, response time characteristics, and approval agency certifications to ensure direct functional equivalence in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GDA-250MA are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Current Rating: 250 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)

Mechanical Equivalence Criteria:

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

Compliance Criteria:

• Approval agencies must include at minimum CCC and CSA certifications
• RoHS compliance status documented

All five substitute parts listed (BK/GDA-250MA, S501-250-R, 0216.250HXP, 0216.250MXP, FCD-250MA) meet these equivalence criteria and are therefore direct functional substitutes for the GDA-250MA in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

• 0216.250HXP and 0216.250MXP include CCC, CSA, and VDE certifications
• FCD-250MA is certified to IEC 60127 standard

Inventory Availability:

• FCD-250MA: 6768 units (highest availability)
• 0216.250MXP: 2076 units
• 0216.250HXP: 1155 units
• BK/GDA-250MA: 756 units
• S501-250-R: 687 units
• GDA-250MA: 748 units

RoHS Compliance:

• BK/GDA-250MA: RoHS Compliant
• S501-250-R: ROHS3 Compliant
• 0216.250HXP: ROHS3 Compliant
• 0216.250MXP: ROHS3 Compliant
• FCD-250MA: ROHS3 Compliant

All parts are suitable for direct substitution based on electrical equivalence and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the GDA-250MA be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts (BK/GDA-250MA, S501-250-R, 0216.250HXP, 0216.250MXP, FCD-250MA) meet the required electrical ratings of 250 mA at 250 V AC with fast-blow response, the mechanical specification of 5mm x 20mm form factor, and the 1.5 kA breaking capacity. Direct substitution is supported by matching these core parameters.

Q: What is the significance of the 5mm x 20mm package specification?

A: The 5mm x 20mm dimension specifies the physical form factor of the ceramic cartridge fuse. This dimension determines compatibility with standard fuse holders designed for this size. All substitute parts share this identical package specification, ensuring mechanical compatibility with existing holder installations.

Q: Are there differences in DC cold resistance among the substitute parts?

A: Yes. The GDA-250MA, BK/GDA-250MA, and S501-250-R each have 4.4 Ohms DC cold resistance, while the Littelfuse parts (0216.250HXP and 0216.250MXP) have 2.35 Ohms. The FCD-250MA does not specify this parameter. These differences reflect manufacturing variations but do not affect the primary circuit protection function at the specified 250 mA rating.

Q: What does "Fast Blow" response time mean?

A: Fast Blow indicates that the fuse will open rapidly when current exceeds the rated 250 mA threshold. All substitute parts share this response characteristic, ensuring consistent overcurrent protection behavior across all equivalent options.

Q: Which substitute part has the highest current inventory?

A: The FCD-250MA from OptiFuse has the highest inventory at 6768 units in stock, followed by 0216.250MXP at 2076 units.

Q: Do all substitute parts have the same approval certifications?

A: No. While all parts include CCC and CSA certifications, the specific approval agencies differ. GDA-250MA includes IMQ and SEMKO; S501-250-R includes BSI, cULus, and VDE; Littelfuse parts include CE and VDE; FCD-250MA is certified to IEC 60127. Selection should confirm that the required certifications for your application are present on the chosen substitute.

Q: What is the breaking capacity specification?

A: The breaking capacity of 1.5 kA indicates the maximum fault current that the fuse can safely interrupt at the rated voltage of 250 V AC. All substitute parts share this identical 1.5 kA specification.
