Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/GDB-V-1A is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)

All substitute parts listed maintain these mandatory parameters. Variations in secondary characteristics such as melting I²t, DC cold resistance, and approval agency certifications do not disqualify substitution when primary electrical and mechanical parameters are identical.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full RoHS compliance, ensuring long-term availability and regulatory conformance. Selection among equivalent parts is based on the following criteria:

Eaton GDB Series (BK/GDB-V-1A): Primary part with UL and VDE approval. Suitable for applications requiring these specific certifications.

Eaton S500 Series (BK/S500-V-1-R): Direct Eaton substitute with expanded approval agency coverage (BSI, CCC, CSA, cULus, IMQ, SEMKO, VDE). Identical electrical characteristics to BK/GDB-V-1A. Bulk packaging available.

Eaton GMA Series (BK/GMA-V-1-R): Parametric equivalent with CSA, PSE, and UL approvals. Melting I²t of 0.48 represents faster thermal response compared to primary part (0.6). Suitable for applications requiring PSE certification.

SCHURTER FSF 5x20 Series (0034.1516.PT): Direct substitute with cURus approval. Operating temperature range specified as -55°C to 125°C. Melting I²t of 1.13 indicates slower thermal response. Highest inventory availability (3748 pcs).

Littelfuse 217 Series (0217001.MXEP): Direct substitute with comprehensive approval agency coverage (BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, VDE). Operating temperature range -55°C to 125°C. Melting I²t of 1.045. Lowest DC cold resistance (0.0964 Ohms).

Frequently Asked Questions (FAQ)

Q: Can BK/GDB-V-1A be replaced with BK/S500-V-1-R in all applications?

A: Yes. Both parts maintain identical current rating (1 A), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast blow), package dimensions (5mm x 20mm axial), and breaking capacity (35 A). The S500 series offers expanded certification coverage.

Q: What is the significance of different melting I²t values among the substitute parts?

A: Melting I²t indicates the thermal energy required to melt the fuse element. Lower values (BK/GMA-V-1-R at 0.48) result in faster thermal response. Higher values (0034.1516.PT at 1.13) result in slower thermal response. All listed parts maintain the same current rating and voltage rating, so substitution is valid; however, application-specific thermal characteristics should be verified if the circuit design depends on precise thermal response timing.

Q: Are all substitute parts suitable for through-hole PCB mounting?

A: Yes. All listed parts are classified as Through Hole mounting type with 5mm x 20mm axial form factor, ensuring mechanical compatibility with standard fuse holders and PCB footprints designed for the BK/GDB-V-1A.

Q: Which substitute part has the broadest regulatory approval coverage?

A: The 0217001.MXEP (Littelfuse 217 series) carries the most comprehensive approval agency certifications: BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE. This part is suitable for applications requiring compliance across multiple international markets.

Q: Can BK/GDB-V-1A be used in applications requiring operating temperatures below 0°C or above 85°C?

A: Operating temperature range is not specified for BK/GDB-V-1A. For applications requiring extended temperature operation, 0034.1516.PT and 0217001.MXEP both specify operating temperature range of -55°C to 125°C and are suitable substitutes for such applications.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant designations?

A: Both designations indicate compliance with RoHS (Restriction of Hazardous Substances) regulations. ROHS3 represents compliance with the most recent RoHS 3 directive. All listed parts meet current RoHS requirements and are suitable for applications with RoHS compliance mandates.

Q: Is DC voltage rating specified for these fuse parts?

A: The parts are rated for 250 V AC. DC voltage rating is not specified in the provided parameters. For DC applications, verify that the circuit design and fuse selection are appropriate for the specific DC voltage and current conditions.
