Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/GDB-V-8A is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 8 A (exact match required)
• Voltage Rating (AC): 250 V (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: 80 A (exact match required)

All identified substitute parts meet these criteria. The primary distinction between substitutes is product status (active vs. obsolete), approval agency certifications, and DC cold resistance specifications.

Parameter Comparison

Engineering Selection Recommendations

BK/S500-V-8-R (Eaton - Electronics Division):

This part is the direct equivalent from the same manufacturer. It maintains identical electrical specifications and mechanical dimensions to the BK/GDB-V-8A while offering active product status. The BK/S500-V-8-R carries expanded approval certifications (BSI, CSA, cULus, SEMKO, VDE) compared to the original part and is RoHS Compliant. This substitute is suitable for direct replacement in applications where Eaton component continuity is required.

0217008.MXEP (Littelfuse Inc.):

This part meets all critical electrical and mechanical parameters with identical current rating, voltage rating, response time, and breaking capacity. The 0217008.MXEP offers the broadest approval agency coverage (BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, VDE) and includes specified operating temperature range (-55°C ~ 125°C). The DC cold resistance is lower (0.0068 Ohms vs. 0.01 Ohms), which may be advantageous in low-resistance circuit applications. Physical dimensions show minor variation (0.228" Dia x 0.886" L vs. 0.218" Dia x 0.831" L), requiring verification of mechanical fit in existing fuse holders. This substitute is suitable for applications requiring multi-regional compliance or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can BK/S500-V-8-R be used as a direct replacement for BK/GDB-V-8A?

A: Yes. Both parts share identical electrical specifications (8 A, 250 V AC, fast-blow response) and mechanical dimensions (5mm x 20mm axial through-hole). The BK/S500-V-8-R is the active equivalent from the same manufacturer.

Q: What is the difference between BK/S500-V-8-R and 0217008.MXEP?

A: Both parts meet all critical electrical and mechanical parameters. Key differences include: manufacturer (Eaton vs. Littelfuse), approval agency certifications, DC cold resistance (0.01 Ohms vs. 0.0068 Ohms), and physical dimensions (5.54mm x 21.10mm vs. 5.80mm x 22.50mm). The 0217008.MXEP includes specified operating temperature range (-55°C ~ 125°C).

Q: Are there mechanical fit considerations when substituting with 0217008.MXEP?

A: The 0217008.MXEP has slightly larger dimensions (0.228" Dia x 0.886" L) compared to the original part (0.218" Dia x 0.831" L). Verification of mechanical fit within the fuse holder is required before implementation.

Q: Which substitute offers the best compliance coverage?

A: The 0217008.MXEP carries the most comprehensive approval agency certifications (BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, VDE) and includes ROHS3 compliance with specified operating temperature range.

Q: Is the lower DC cold resistance of 0217008.MXEP (0.0068 Ohms) significant?

A: The difference between 0.0068 Ohms and 0.01 Ohms is minor and typically not significant in standard circuit protection applications. Applications with extremely low-resistance circuits may benefit from the lower resistance value.

Q: What is the inventory status of these substitutes?

A: BK/S500-V-8-R has 1016 pieces in stock. 0217008.MXEP has 2000 pieces in stock. Both are available as new original components.
