Littelfuse 0230.600MXP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0230.600MXP is a 600 mA, 250 V AC / 125 V DC glass cartridge fuse with slow-blow response characteristics. This through-hole mounted component is designed for circuit protection in applications requiring non-standard axial cartridge form factors. The part maintains active product status with full compliance to CE, CSA, and UL approval agencies. Equivalent and substitute parts are identified when identical electrical ratings, response time, and mechanical compatibility are maintained across the specified parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0230.600MXP are identified based on strict equivalence across the following critical parameters:

• Current Rating: 600 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Through Hole (exact match required)
• Approval Agency: Minimum CSA and UL certification required

The 0230.600HXP (Littelfuse) qualifies as a parametric equivalent, maintaining identical electrical specifications, response characteristics, and dimensional compatibility. The BK/C515-600-R (Eaton - Electronics Division) is identified as a manufacturer-recommended substitute, with the following considerations: it maintains the 600 mA current rating, 250 V AC voltage rating, and slow-blow response time. However, the BK/C515-600-R uses a 2AG package form factor (5mm x 15mm) rather than the non-standard axial cartridge, and does not specify a DC voltage rating. Mechanical compatibility must be verified for socket and mounting configurations.

Parameter Comparison

Engineering Selection Recommendations

The 0230.600HXP is a direct parametric equivalent to the 0230.600MXP. Both parts are manufactured by Littelfuse Inc., maintain identical electrical ratings, response characteristics, and dimensional specifications, and carry equivalent compliance certifications (CE, CSA, UL). Selection between these two parts may be based on inventory availability and lead time considerations.

The BK/C515-600-R (Eaton - Electronics Division) is identified as a manufacturer-recommended alternative. This part maintains the critical electrical parameters: 600 mA current rating, 250 V AC voltage rating, and slow-blow response time. However, the following differences must be evaluated for application compatibility:

• Package form factor differs: 2AG (5mm x 15mm) versus non-standard axial cartridge (4.50mm x 14.50mm)
• DC voltage rating is not specified for the BK/C515-600-R
• Melting I²t value is significantly higher (6.982 versus 1.75), indicating different thermal response characteristics
• DC cold resistance differs (0.38 Ohms versus 0.4805 Ohms)

The BK/C515-600-R is suitable only when the application socket and mounting configuration accommodate the 2AG package form factor, and when DC circuit protection is not a requirement or when the higher I²t value is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the 0230.600HXP be used as a direct replacement for the 0230.600MXP?

A: Yes. The 0230.600HXP is a parametric equivalent with identical current rating (600 mA), voltage ratings (250 V AC / 125 V DC), response time (slow blow), package form factor (non-standard axial cartridge), and approval certifications (CE, CSA, UL). No design modifications are required.

Q: Is the BK/C515-600-R compatible with the 0230.600MXP application?

A: The BK/C515-600-R maintains electrical equivalence for AC circuits (600 mA, 250 V AC, slow blow). However, mechanical compatibility depends on the socket and mounting configuration. The BK/C515-600-R uses a 2AG package (5mm x 15mm) rather than the non-standard axial cartridge (4.50mm x 14.50mm). Additionally, the BK/C515-600-R does not specify a DC voltage rating, and its melting I²t value (6.982) differs significantly from the 0230.600MXP (1.75). Application compatibility must be confirmed before substitution.

Q: What are the key differences in thermal response between the main part and the Eaton substitute?

A: The melting I²t value indicates thermal response characteristics. The 0230.600MXP has a melting I²t of 1.75, while the BK/C515-600-R has a melting I²t of 6.982. This difference means the Eaton part will tolerate higher thermal energy before melting, resulting in different trip characteristics. The choice between these parts depends on the specific thermal protection requirements of the application.

Q: Are all substitute parts RoHS compliant?

A: The 0230.600MXP and 0230.600HXP are both ROHS3 Compliant. The BK/C515-600-R is RoHS Compliant. Both compliance levels meet current regulatory requirements; the specific designation difference reflects manufacturing process variations between suppliers.

Q: What approval certifications are required for my application?

A: The 0230.600MXP and 0230.600HXP carry CE, CSA, and UL certifications. The BK/C515-600-R carries CSA and UL certifications. If CE certification is a requirement for your application, the BK/C515-600-R is not suitable. The Littelfuse parts (0230.600MXP and 0230.600HXP) are appropriate for applications requiring all three certifications.
