BK/C519-600-R Equivalent & Substitute Parts

Part Overview

The BK/C519-600-R is a 600 mA, 250 V AC slow-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This fuse is designed for use in 2AG holders and requires external mounting hardware. The part is currently active in production with 730 pieces in stock. Glass cartridge fuses of this specification are essential protective components in electrical circuits where overcurrent protection and controlled response time are required. Substitute parts may be necessary due to inventory availability, supply chain considerations, or specific application requirements within the allowable electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The 0229.600HXP manufactured by Littelfuse Inc. qualifies as a direct substitute for the BK/C519-600-R based on the following critical parameters:

Matching Parameters:

• Current Rating: 600 mA (identical)
• Voltage Rating - AC: 250 V (identical)
• Fuse Type: Cartridge, Glass (identical)
• Response Time: Slow Blow (identical)
• Package / Case: 2AG, 5mm x 15mm (identical)
• Breaking Capacity @ Rated Voltage: 35A AC (identical)
• Mounting Type: Requires Holder (identical)

Additional Capabilities: The Littelfuse 0229.600HXP provides supplementary DC voltage rating (125 V DC) and extended operating temperature range (-55°C ~ 125°C), which do not restrict its use in applications designed for the BK/C519-600-R but may offer enhanced performance in specific environments.

Parameter Comparison

Engineering Selection Recommendations

Both the BK/C519-600-R and 0229.600HXP are active production parts with established regulatory approvals. The BK/C519-600-R carries CSA and UL certifications, while the 0229.600HXP carries CE, CSA, and UL certifications. Selection between these parts should be based on:

1. Regulatory Requirements: Applications requiring CE compliance should use the 0229.600HXP. Both parts satisfy CSA and UL requirements.

2. Environmental Conditions: The 0229.600HXP specifies an operating temperature range of -55°C ~ 125°C, providing defined thermal performance. The BK/C519-600-R does not specify operating temperature limits.

3. DC Application Capability: The 0229.600HXP is rated for 125 V DC operation, enabling use in DC circuits. The BK/C519-600-R does not specify DC voltage rating.

4. Physical Dimensions: Minor dimensional variations exist (diameter and length). Verify holder compatibility with specific mounting hardware.

5. Compliance Status: Both parts are RoHS compliant. The 0229.600HXP carries ROHS3 compliance and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 0229.600HXP be used as a direct replacement for the BK/C519-600-R in all applications?

A: Yes, for AC applications at 250 V and 600 mA. The 0229.600HXP meets or exceeds all critical electrical parameters (current rating, AC voltage rating, breaking capacity, response time) and physical specifications (2AG package, 5mm x 15mm form factor). Both parts require external holders and are approved by CSA and UL.

Q: What is the significance of the different Melting I²t values?

A: The Melting I²t value (6.982 for BK/C519-600-R versus 1.75 for 0229.600HXP) indicates the thermal energy required to melt the fuse element. The lower value for the Littelfuse part indicates faster thermal response under fault conditions. Both parts are classified as slow-blow fuses and are suitable for applications requiring controlled overcurrent protection.

Q: Are there physical compatibility concerns when substituting these parts?

A: Minor dimensional differences exist. The BK/C519-600-R measures 0.205" diameter x 0.571" length, while the 0229.600HXP measures 0.177" diameter x 0.570" length. Both conform to the 2AG standard and 5mm x 15mm specification. Verify that the specific fuse holder accommodates both diameter specifications.

Q: Which part should be selected for applications requiring DC operation?

A: The 0229.600HXP is rated for 125 V DC operation and is suitable for DC circuits. The BK/C519-600-R does not specify DC voltage rating and should not be assumed for DC applications.

Q: What compliance advantages does the 0229.600HXP offer?

A: The 0229.600HXP carries CE certification in addition to CSA and UL approvals, making it suitable for European market applications. It also carries ROHS3 compliance and REACH Unaffected status, providing broader regulatory coverage than the BK/C519-600-R.
