Littelfuse 0230.250VXP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0230.250VXP is a 250 mA, 250 V AC / 125 V DC glass cartridge fuse with slow-blow response characteristics. This non-standard axial cartridge fuse is designed for through-hole mounting applications requiring circuit protection in the specified voltage and current range. The part maintains active product status with full regulatory compliance (CE, CSA, UL). Equivalent and substitute parts are identified when identical electrical ratings and mechanical compatibility are maintained across the specified parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0230.250VXP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Current Rating: 250 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) or equivalent 2AG form factor (exact match required)
• Size / Dimension: 4.50mm x 14.50mm or 5.50mm x 15.20mm (within tolerance for mechanical fit)

Regulatory & Compliance Requirements:

• Regulatory Approvals: CE, CSA, UL certifications (minimum CSA and UL required)
• RoHS Status: ROHS3 Compliant (exact match required)

Parametric equivalents 0230.250HXP and 0230.250MXP meet all electrical and mechanical criteria. The Eaton BK/C515-250-R represents a manufacturer-recommended alternative with compatible 2AG form factor, though with dimensional variation (5.50mm x 15.20mm).

Parameter Comparison

Engineering Selection Recommendations

Littelfuse 0230.250HXP and 0230.250MXP are direct parametric equivalents to the 0230.250VXP. All three parts share identical electrical ratings (250 mA, 250 V AC, 125 V DC), response characteristics (slow blow), mechanical form factor (4.50mm x 14.50mm non-standard axial cartridge), and regulatory certifications (CE, CSA, UL). Both alternatives maintain ROHS3 compliance and active product status. Selection between these three Littelfuse parts may be based on inventory availability and application-specific breaking capacity requirements.

Eaton BK/C515-250-R is a manufacturer-recommended alternative that maintains electrical equivalence (250 mA, 250 V AC, slow blow) and regulatory compliance (CSA, UL). However, this part uses the 2AG form factor with dimensions of 5.50mm x 15.20mm, representing a mechanical variation from the original 4.50mm x 14.50mm specification. The BK/C515-250-R exhibits different thermal characteristics (Melting I²t of 0.467 versus 0.216) and lower DC cold resistance (1.32 Ohms versus 2.43 Ohms). Mechanical fit verification is required before substitution in existing through-hole cartridge fuse holders designed for the non-standard axial form factor.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0230.250HXP directly replace the 0230.250VXP?

A: Yes. Both parts are identical in current rating (250 mA), AC voltage rating (250 V), DC voltage rating (125 V), response time (slow blow), fuse type (cartridge glass), mounting type (through hole), mechanical dimensions (4.50mm x 14.50mm), and regulatory approvals (CE, CSA, UL). Direct substitution is supported without circuit modification.

Q: What is the difference between the 0230.250VXP and 0230.250MXP?

A: The 0230.250VXP and 0230.250MXP are electrically and mechanically identical. Both carry the same current rating, voltage ratings, response time, fuse type, dimensions, and regulatory certifications. Differences exist only in breaking capacity specifications (0230.250VXP: 35A AC / 10kA DC; 0230.250MXP: 35A AC / 10kA DC) and inventory availability.

Q: Can the Eaton BK/C515-250-R be used as a substitute for the 0230.250VXP?

A: The Eaton BK/C515-250-R maintains electrical equivalence in current rating (250 mA) and AC voltage rating (250 V) with slow-blow response. However, the BK/C515-250-R uses a 2AG form factor with dimensions of 5.50mm x 15.20mm, compared to the original 4.50mm x 14.50mm non-standard axial cartridge. Mechanical compatibility with existing fuse holders must be verified. Additionally, the BK/C515-250-R does not specify a DC voltage rating and exhibits different thermal characteristics (Melting I²t: 0.467 versus 0.216).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact equivalence in current rating (250 mA), AC voltage rating (250 V), DC voltage rating (125 V), response time (slow blow), fuse type (cartridge glass), mounting type (through hole), mechanical form factor (axial cartridge), and regulatory certifications (minimum CSA and UL). Dimensional compatibility with existing fuse holders is also required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 0230.250VXP, 0230.250HXP, 0230.250MXP, and BK/C515-250-R are all ROHS3 compliant.

Q: What is the operating temperature range for these fuses?

A: The Littelfuse parts (0230.250VXP, 0230.250HXP, 0230.250MXP) operate across -55°C to 125°C. The Eaton BK/C515-250-R does not specify an operating temperature range in the provided data.
