Substitute Part Grouping Explanation

Substitution eligibility for the 0234010.MXBP is determined by strict equivalence across the following critical parameters:

• Current Rating: 10 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Medium Blow (exact match required)
• Physical Dimensions: 5mm x 20mm (exact match required)
• Breaking Capacity: 200 A (exact match required)
• Melting I²t: 129.025 (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Regulatory Approvals: CE, CSA, K-MARK, PSE, UL (all certifications required)

The identified substitute part 0234010.MXP meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

Both the 0234010.MXBP and 0234010.MXP maintain Active product status with identical regulatory compliance across all required certifications: CE, CSA, K-MARK, PSE, and UL. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards. The parts are functionally equivalent for all circuit protection applications requiring 10 A, 250 V AC/DC ceramic cartridge fuses with medium-blow response in 5mm x 20mm form factors. Selection between these part numbers may be based on inventory availability or packaging configuration requirements, as electrical and mechanical performance characteristics are identical.

Frequently Asked Questions (FAQ)

Q: Can 0234010.MXP be used as a direct replacement for 0234010.MXBP?
