Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0230003.MXF23P is determined by strict equivalence across the following critical parameters:

• Current Rating: 3 A (exact match required)
• Voltage Rating AC: 250 V (exact match required)
• Voltage Rating DC: 125 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Physical Dimensions: 0.177" Dia x 0.571" L / 4.50mm x 14.50mm (exact match required)
• Approval Agencies: CE, CSA, PSE, UL (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute parts 0230003.HXP and 0230003.MXP meet all critical electrical, mechanical, and regulatory parameters and are therefore classified as parametric equivalents within the Littelfuse 230 series.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0230003.MXF23P, 0230003.HXP, and 0230003.MXP—are Active status products from Littelfuse Inc. and carry identical electrical specifications, mechanical dimensions, and regulatory certifications. Selection among these equivalents may be based on procurement availability and inventory levels. All parts maintain ROHS3 compliance and full international approval coverage (CE, CSA, PSE, UL), ensuring regulatory conformance across global applications.

Frequently Asked Questions (FAQ)

Q: Can 0230003.HXP or 0230003.MXP be used as direct replacements for 0230003.MXF23P?

A: Yes. Both parts are parametric equivalents meeting identical electrical ratings (3 A, 250 V AC, 125 V DC), fuse type (cartridge, glass), response time (slow blow), physical dimensions (0.177" Dia x 0.571" L), and regulatory certifications. Direct substitution is supported.

Q: Are there differences in breaking capacity between these parts?

A: The 0230003.MXF23P specifies 100 A AC breaking capacity, while 0230003.HXP and 0230003.MXP specify 35 A AC breaking capacity. Both meet the rated voltage breaking capacity requirements for their respective designs.

Q: Do all three parts have the same mounting compatibility?

A: Yes. All three parts are through-hole mounted cartridge fuses in non-standard axial configuration with identical physical dimensions, ensuring mechanical and electrical compatibility in the same circuit positions.

Q: Are all parts RoHS and internationally certified?

A: Yes. All three parts are ROHS3 compliant and carry CE, CSA, PSE, and UL approvals, meeting global regulatory requirements for equivalent component selection.
