Littelfuse 0230.600HXP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0230.600HXP is a 600 mA, 250 V AC / 125 V DC glass cartridge fuse with slow-blow response characteristics. This through-hole component is designed for circuit protection in applications requiring reliable overcurrent interruption across AC and DC voltage domains. The part maintains active product status with full regulatory compliance (CE, CSA, UL) and is RoHS3 compliant. Equivalent and substitute parts are identified when identical electrical parameters and mechanical compatibility are maintained across the specified voltage and current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0230.600HXP is determined by strict equivalence across the following critical parameters:

• Current Rating: 600 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required for DC applications)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity: 35A AC minimum, 10kA DC minimum
• Operating Temperature Range: -55°C to 125°C (minimum coverage required)
• Regulatory Compliance: CE, CSA, UL certifications

The 0230.600MXP (Littelfuse) is a parametric equivalent with identical electrical and mechanical specifications. The BK/C515-600-R (Eaton - Electronics Division) is a manufacturer-recommended substitute with equivalent current and AC voltage ratings; however, it operates in the 2AG package format (5mm x 15mm) with different mechanical dimensions and does not specify a DC voltage rating, requiring mechanical and electrical compatibility verification in the target application.

Parameter Comparison

Engineering Selection Recommendations

The 0230.600MXP (Littelfuse) is a direct parametric equivalent to the 0230.600HXP. Both parts share identical electrical ratings, mechanical dimensions, response characteristics, and regulatory certifications (CE, CSA, UL). Selection between these two Littelfuse variants is based on inventory availability and supply chain considerations, with no functional or compliance differences.

The BK/C515-600-R (Eaton - Electronics Division) is a manufacturer-recommended alternative for AC-only applications. This part maintains the 600 mA current rating and 250 V AC voltage rating with equivalent slow-blow response. However, the following differences require evaluation:

• Package format differs (2AG 5mm x 15mm versus non-standard 4.50mm x 14.50mm), necessitating mechanical compatibility verification with the target circuit board or fuse holder.
• DC voltage rating is not specified, limiting applicability to DC or mixed AC/DC circuits.
• Melting I²t value (6.982) differs from the primary part (1.75), indicating different thermal response characteristics.
• Regulatory coverage includes CSA and UL but does not list CE certification.

Selection of the BK/C515-600-R is appropriate only when the application operates exclusively on AC power, the mechanical package is compatible with available fuse holders, and the absence of DC voltage specification does not conflict with circuit requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. The 0230.600MXP is a parametric equivalent with identical current rating (600 mA), voltage ratings (250 V AC / 125 V DC), response time (slow blow), mechanical dimensions (4.50mm x 14.50mm), and regulatory certifications (CE, CSA, UL). No circuit modifications are required.

Q: Is the BK/C515-600-R compatible with the 0230.600HXP in all applications?

A: The BK/C515-600-R is compatible only in AC-only applications. The part does not specify a DC voltage rating, and its 2AG package format (5mm x 15mm) differs mechanically from the 0230.600HXP (4.50mm x 14.50mm). Fuse holder compatibility must be verified before substitution. Applications requiring DC protection should use the 0230.600MXP or 0230.600HXP.

Q: What is the significance of the different Melting I²t values between the 0230.600HXP and BK/C515-600-R?

A: The Melting I²t value (1.75 versus 6.982) indicates the thermal energy required to melt the fuse element. The BK/C515-600-R has a higher I²t, meaning it tolerates greater transient energy before opening. This difference may affect circuit protection characteristics in applications with inrush currents or transient conditions. Verify that the BK/C515-600-R thermal response is acceptable for the target application.

Q: Are all three parts RoHS compliant?

A: The 0230.600HXP and 0230.600MXP are RoHS3 compliant. The BK/C515-600-R is RoHS compliant (RoHS 2). Both compliance levels are acceptable for most applications; however, verify specific RoHS revision requirements for your end-use market.

Q: Which substitute part should I select for a new design?

A: For new designs requiring both AC and DC protection with identical mechanical and electrical characteristics, use the 0230.600MXP (Littelfuse). For AC-only applications where mechanical package flexibility exists, the BK/C515-600-R (Eaton) is acceptable if fuse holder compatibility is confirmed and the higher Melting I²t value does not conflict with circuit protection requirements.
