Littelfuse 0230.500VXP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0230.500VXP is a 500 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 geometry (4.50mm diameter × 14.50mm length). 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 parameters are maintained across the component selection.

Substitute Part Grouping Explanation

Substitute parts for the 0230.500VXP are classified into two categories based on parametric equivalence:

Parametric Equivalents (Littelfuse Series 230): The parts 0230.500HXP and 0230.500MXP are direct parametric equivalents manufactured by Littelfuse Inc. These substitutes maintain identical electrical specifications (500 mA, 250 V AC, 125 V DC), response time (Slow Blow), mechanical dimensions (4.50mm × 14.50mm), breaking capacity (35A AC, 10kA DC), and thermal characteristics (-55°C to 125°C). All three parts share the same non-standard axial cartridge package geometry, DC cold resistance (0.6935 Ohms), melting I²t value (1.16), and regulatory compliance (CE, CSA, UL, ROHS3).

Manufacturer Recommended Substitute (Eaton Electronics Division): The part BK/C515-500-R is a manufacturer-recommended substitute from Eaton Electronics Division. This part maintains the same current rating (500 mA), AC voltage rating (250 V), response time (Slow Blow), fuse type (Cartridge, Glass), and mounting method (Through Hole). However, this substitute uses a standard 2AG package format (5mm × 15.20mm) rather than the non-standard axial geometry of the primary part. The breaking capacity remains equivalent at 35A AC. Key differences include a higher melting I²t value (2.28 versus 1.16) and lower DC cold resistance (0.54 Ohms versus 0.6935 Ohms). The Eaton part does not specify a DC voltage rating and carries CSA and UL approvals without CE certification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Mechanical Fit): The Littelfuse 0230.500HXP and 0230.500MXP are recommended as primary substitutes when mechanical compatibility with existing through-hole cartridge holders designed for non-standard axial geometry (4.50mm × 14.50mm) is required. Both parts maintain complete parametric equivalence with the 0230.500VXP, including identical current ratings, voltage specifications, response characteristics, and regulatory certifications (CE, CSA, UL). Selection between these two Littelfuse equivalents may be based on inventory availability and lead time considerations.

For Alternative Package Geometry: The Eaton BK/C515-500-R is suitable only when the circuit design accommodates the standard 2AG package format (5.50mm × 15.20mm). This substitute maintains electrical equivalence for AC applications at 250 V and 500 mA with slow-blow response. However, the absence of a specified DC voltage rating and the lack of CE certification should be evaluated against application requirements. The higher melting I²t value (2.28) indicates a different thermal response profile compared to the primary part (1.16), which may affect circuit protection timing in specific applications. This substitute is appropriate only when mechanical constraints permit the larger 2AG package and when DC voltage operation is not required or when DC operation is limited to applications where the unspecified rating is acceptable.

All substitute parts maintain ROHS3 compliance and active product status, ensuring continued availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 0230.500HXP and 0230.500MXP be used interchangeably with the 0230.500VXP?

A: Yes. The 0230.500HXP and 0230.500MXP are parametric equivalents with identical electrical ratings (500 mA, 250 V AC, 125 V DC), response time (Slow Blow), mechanical dimensions (4.50mm × 14.50mm), breaking capacity, and regulatory certifications. Direct substitution is supported without circuit modification.

Q: What is the primary difference between the Littelfuse 230 series substitutes and the Eaton BK/C515-500-R?

A: The Littelfuse 0230.500HXP and 0230.500MXP use a non-standard axial cartridge package (4.50mm × 14.50mm), while the Eaton BK/C515-500-R uses a standard 2AG package (5.50mm × 15.20mm). This dimensional difference affects mechanical compatibility with existing fuse holders. Additionally, the Eaton part does not specify a DC voltage rating and lacks CE certification.

Q: Can the Eaton BK/C515-500-R be used as a substitute in applications requiring 125 V DC operation?

A: The Eaton BK/C515-500-R does not specify a DC voltage rating in the provided technical data. Applications requiring 125 V DC operation should use the Littelfuse 0230.500HXP or 0230.500MXP, which explicitly maintain this specification.

Q: Are there differences in thermal response between these substitute parts?

A: The Littelfuse 0230.500VXP, 0230.500HXP, and 0230.500MXP share identical melting I²t values (1.16) and operating temperature ranges (-55°C to 125°C). The Eaton BK/C515-500-R has a higher melting I²t value (2.28) and does not specify an operating temperature range, indicating different thermal response characteristics.

Q: Do all substitute parts carry the same regulatory certifications?

A: The Littelfuse 0230.500HXP and 0230.500MXP carry CE, CSA, and UL certifications matching the primary part. The Eaton BK/C515-500-R carries CSA and UL certifications but does not include CE certification.

Q: What should be considered when selecting between the three Littelfuse equivalents?

A: All three Littelfuse parts (0230.500VXP, 0230.500HXP, 0230.500MXP) are electrically and mechanically identical. Selection may be based on inventory availability, lead time, and cost considerations. The choice between them does not affect circuit performance or compatibility.
