BK/S500-V-10-R Equivalent & Substitute Parts Reference

Part Overview

The BK/S500-V-10-R is a 10 A 250 V AC DC glass cartridge fuse with fast blow response time, manufactured by Eaton - Electronics Division in a 5mm x 20mm axial through-hole package. This part is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/S500-V-10-R are qualified based on strict electrical and mechanical parameter matching:

Electrical Parameters (Must Match):

• Current Rating: 10 A
• Voltage Rating (AC): 250 V
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 100 A

Mechanical Parameters (Must Match):

• Fuse Type: Cartridge, Glass
• Package / Case: 5mm x 20mm (Axial)
• Mounting Type: Through Hole

All three substitute parts listed below meet these mandatory criteria and are sourced from active manufacturers with current product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute Candidates:

All three substitute parts are functionally equivalent to the BK/S500-V-10-R based on matching electrical and mechanical parameters. Selection among these active alternatives should be based on the following factors:

Compliance & Certifications:

• 0034.1526.PT (SCHURTER): Holds cURus, PSE/JET, and VDE approvals. RoHS3 compliant. REACH unaffected.
• 0217010.MXEP (Littelfuse): Holds CE, K-MARK, and PSE approvals. RoHS3 compliant. REACH unaffected.
• 5SFP 10-R (Bel Fuse): Holds CE, CSA, and cULus approvals. RoHS3 compliant. REACH unaffected.

Inventory Availability:

• 0217010.MXEP (Littelfuse): 2400 Pcs in stock
• 0034.1526.PT (SCHURTER): 1738 Pcs in stock
• 5SFP 10-R (Bel Fuse): 1625 Pcs in stock

Physical Dimensions: All parts fit the 5mm x 20mm package specification. Minor dimensional variations exist within tolerance:

• BK/S500-V-10-R: 0.218" Dia x 0.831" L
• 0034.1526.PT: 0.213" Dia x 0.886" L
• 0217010.MXEP: 0.228" Dia x 0.886" L
• 5SFP 10-R: 0.217" Dia x 0.827" L

These dimensional differences remain within the 5mm x 20mm axial cartridge fuse standard and do not affect through-hole mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts directly in place of the BK/S500-V-10-R?

A: Yes. All three substitute parts meet the mandatory electrical and mechanical parameters: 10 A current rating, 250 V AC voltage rating, fast blow response, 100 A breaking capacity, and 5mm x 20mm axial through-hole package. They are direct functional equivalents.

Q: What is the difference between these substitute parts?

A: The substitute parts differ in manufacturer, approval agency certifications, and minor physical dimensions. All meet the core electrical specifications. Selection should be based on your specific compliance requirements and supply chain preferences.

Q: Are there any compatibility concerns with PCB mounting?

A: No. All parts are through-hole mounted cartridge fuses in the 5mm x 20mm axial package. Physical dimension variations are minor and within standard tolerance for this package type. Existing PCB footprints designed for the BK/S500-V-10-R accommodate all substitute parts.

Q: Which substitute part should I choose for new designs?

A: Selection depends on your certification requirements. If CSA or cULus approval is required, use 5SFP 10-R (Bel Fuse). If VDE approval is required, use 0034.1526.PT (SCHURTER). If K-MARK or PSE approval is required, use 0217010.MXEP (Littelfuse). All are RoHS3 compliant and REACH unaffected.

Q: What is the melting I²t specification, and why does it vary?

A: Melting I²t is a thermal characteristic that indicates the energy required to melt the fuse element. Variations among substitute parts (0034.1526.PT: 183, 0217010.MXEP: 217.635, 5SFP 10-R: 163) reflect different internal fuse element designs. All parts maintain the same fast blow response classification and 10 A current rating. Verify melting I²t compatibility with your circuit protection requirements if this parameter is critical to your application.

Q: Is the BK/S500-V-10-R still available?

A: No. The BK/S500-V-10-R is classified as obsolete. Use one of the three active substitute parts listed in this reference.
