Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GDA-1A is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (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 characteristics such as Melting I²t, DC Cold Resistance, Operating Temperature range, and approval agency certifications do not disqualify substitution when primary electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are in active production status and meet the critical electrical and mechanical specifications of the GDA-1A. Selection among substitutes may be based on the following factors derived from provided data:

Eaton - Electronics Division Parts (BK/GDA-1A, BK1/S501-1-R, S501-1-R): These parts maintain identical Melting I²t (0.146) and DC Cold Resistance (0.231 Ohms) to the main part. BK1/S501-1-R and S501-1-R carry RoHS3 compliance certification. All three carry CCC and SEMKO approvals.

Littelfuse Inc. Parts (0216001.MXP, 0216001.VXP): Both parts carry the broadest approval agency coverage including CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE. Operating temperature range is specified as -55°C ~ 125°C. Both are RoHS3 compliant. Melting I²t is 0.18 and DC Cold Resistance is 0.237 Ohms.

SCHURTER Inc. Part (0001.1004): Carries CCC, cURus, KC, PSE/JET, and VDE approvals. Operating temperature range is -55°C ~ 125°C. RoHS3 compliant. Melting I²t is 0.75.

OptiFuse Part (FCD-1A): Carries IEC 60127 certification. Operating temperature range is -55°C ~ 125°C. RoHS3 compliant. Melting I²t is 0.2019. Includes 250 V DC voltage rating specification.

Frequently Asked Questions (FAQ)

Q: Can BK/GDA-1A be used as a direct replacement for GDA-1A?

A: Yes. BK/GDA-1A is manufactured by the same company (Eaton - Electronics Division) and shares identical electrical characteristics, mechanical dimensions, response time, and breaking capacity. Both are in active production status.

Q: What is the difference between S501-1-R and BK1/S501-1-R?

A: Both parts are manufactured by Eaton - Electronics Division and meet all critical electrical and mechanical specifications. BK1/S501-1-R carries RoHS3 compliance certification, while S501-1-R does not specify RoHS status in the provided data. Both carry identical Melting I²t (0.146) and DC Cold Resistance (0.231 Ohms).

Q: Are Littelfuse 0216001.MXP and 0216001.VXP interchangeable?

A: Yes. Both parts are from the same manufacturer series (216), carry identical electrical ratings, mechanical dimensions, breaking capacity, and approval certifications. Both are RoHS3 compliant with -55°C ~ 125°C operating temperature range.

Q: Does the Melting I²t variation affect substitution eligibility?

A: Melting I²t is a secondary characteristic that reflects thermal energy dissipation during fuse operation. All substitute parts meet the critical electrical and mechanical parameters required for direct replacement. Variations in Melting I²t (ranging from 0.146 to 0.75 across the substitute list) do not disqualify substitution when primary specifications are identical.

Q: Which substitute part has the widest approval agency coverage?

A: Littelfuse parts 0216001.MXP and 0216001.VXP carry approvals from CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE, representing the broadest certification coverage among all substitutes.

Q: Can FCD-1A be used in applications requiring DC voltage rating?

A: FCD-1A specifies both 250 V AC and 250 V DC voltage ratings. Other substitute parts specify only 250 V AC. For applications requiring explicit DC voltage rating, FCD-1A provides documented DC capability.

Q: Are all substitute parts available in the same 5mm x 20mm package?

A: Yes. All identified substitute parts use the 5mm x 20mm cartridge package and require a compatible holder for installation, matching the GDA-1A mounting requirement.
