Equivalent & Substitute Parts for BK/GDB-V-5A

Part Overview

The BK/GDB-V-5A is a 5 A, 250 V AC/DC fast-blow glass cartridge fuse with a 5mm x 20mm axial through-hole package manufactured by Eaton Electronics Division. This component is classified as obsolete product status. Due to its obsolescence, equivalent substitute parts from active product lines are necessary to maintain circuit protection functionality in applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/GDB-V-5A is determined by strict equivalence across the following critical parameters:

• Current Rating: 5 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: 50 A (exact match required)

All substitute parts listed below meet these criteria. Variations in melting I²t, DC cold resistance, physical dimensions within tolerance, and approval agency certifications do not disqualify substitution when all primary parameters align.

Engineering Selection Recommendations

Primary Recommendation: BK/S500-V-5-R

The BK/S500-V-5-R is the direct manufacturer equivalent from Eaton Electronics Division. This part maintains active product status and provides identical electrical and mechanical specifications to the obsolete BK/GDB-V-5A. It carries RoHS compliance certification and broader approval agency coverage (BSI, CCC, CSA, cULus, IMQ, SEMKO, VDE). Current inventory is 872 units.

Secondary Recommendation: 0217005.MXEP

The 0217005.MXEP from Littelfuse is a parametric equivalent meeting all critical electrical and mechanical requirements. This part offers the highest current inventory (12,012 units) and carries comprehensive international approvals (BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, VDE). ROHS3 compliance and REACH unaffected status are provided. Operating temperature range is specified as -55°C to 125°C.

Tertiary Recommendation: 0034.1523.PT

The 0034.1523.PT from SCHURTER Inc. meets all substitution criteria with active product status and ROHS3 compliance. Inventory availability is 1,271 units. Operating temperature range is -55°C to 125°C. Melting I²t is 33.8, which is lower than the main part specification of 42.

Alternative: BK/S500-V-5-RS

The BK/S500-V-5-RS is an Eaton equivalent with identical electrical specifications. This part carries RoHS non-compliant status and is suitable for applications where RoHS compliance is not required. Inventory is 886 units.

Frequently Asked Questions (FAQ)

Q: Can BK/S500-V-5-R be used as a direct replacement for BK/GDB-V-5A?

A: Yes. The BK/S500-V-5-R meets all critical electrical and mechanical parameters: 5 A current rating, 250 V AC voltage rating, fast-blow response, 5mm x 20mm package, 50 A breaking capacity, and 42 melting I²t. Both are manufactured by Eaton Electronics Division.

Q: What is the difference between BK/S500-V-5-R and BK/S500-V-5-RS?

A: Both parts are electrically and mechanically identical. The primary difference is RoHS compliance status: BK/S500-V-5-R is RoHS Compliant, while BK/S500-V-5-RS is RoHS non-compliant. Select based on application regulatory requirements.

Q: Why is the melting I²t value different for 0034.1523.PT (33.8 vs. 42)?

A: Melting I²t is a thermal characteristic that varies by manufacturer design. The 0034.1523.PT value of 33.8 remains within acceptable substitution parameters as all other critical specifications (current, voltage, response time, package, breaking capacity) are identical. This part is suitable for applications where the main part specifications are required.

Q: Is 0217005.MXEP from Littelfuse compatible with the original BK/GDB-V-5A circuit design?

A: Yes. The 0217005.MXEP meets all electrical and mechanical equivalence criteria: 5 A, 250 V AC, fast-blow, 5mm x 20mm through-hole package, and 50 A breaking capacity. Physical dimensions are within tolerance (5.80mm diameter vs. 5.54mm nominal). This part is suitable for direct substitution.

Q: Which substitute part has the best availability?

A: The 0217005.MXEP from Littelfuse has the highest inventory at 12,012 units in stock.

Q: Are all substitute parts approved for the same applications?

A: All substitute parts carry relevant international approvals (UL, VDE, CSA, or equivalent). Verify specific application requirements against the approval agency list for each part. BK/S500-V-5-R and 0217005.MXEP carry the broadest certification coverage.

Q: Can I use these fuses interchangeably in the same circuit board?

A: Yes, provided the circuit board footprint accommodates the 5mm x 20mm axial through-hole package. All substitute parts use identical package geometry and mounting type.
