Littelfuse 022401.5VXP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 022401.5VXP is a 1.5 A fast-blow glass cartridge fuse rated for 250 V AC and 125 V DC operation. This through-hole component is housed in a 2AG package (5mm x 15mm axial form factor) and is designed for circuit protection applications requiring reliable overcurrent interruption. The part maintains active product status with full compliance to international safety standards including CE, CSA, PSE, and UL certifications. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same fuse category and package specification.

Substitute Part Grouping Explanation

Substitute parts for the 022401.5VXP are identified based on strict equivalence across the following critical parameters:

• Current Rating: 1.5 A
• Voltage Rating: 250 V AC / 125 V DC
• Fuse Type: Cartridge, Glass
• Response Time: Fast Blow
• Package / Case: 2AG, 5mm x 15mm (Axial)
• Mounting Type: Through Hole
• Breaking Capacity: 35 A AC, 10 kA DC
• Melting I²t: 0.8
• Approval Agencies: CE, CSA, PSE, UL
• RoHS Compliance: ROHS3 Compliant

All substitute parts must maintain identical electrical performance characteristics and physical form factor to ensure direct interchangeability in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 022401.5VXP and 022401.5HXP maintain active product status with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and packaging preferences, as both components satisfy the same circuit protection requirements and carry equivalent international safety certifications (CE, CSA, PSE, UL). Both parts are ROHS3 compliant and suitable for applications requiring 1.5 A fast-blow protection at 250 V AC / 125 V DC ratings.

Frequently Asked Questions (FAQ)

Q: Can the 022401.5HXP be used as a direct replacement for the 022401.5VXP?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical current ratings (1.5 A), voltage ratings (250 V AC / 125 V DC), fuse type (cartridge glass), response time (fast blow), package specification (2AG, 5mm x 15mm axial), and breaking capacity (35 A AC, 10 kA DC). Direct substitution is permissible in circuit protection applications.

Q: What determines substitutability for this fuse category?

A: Substitutability is determined by equivalence across current rating, AC/DC voltage ratings, fuse type, response time, package form factor, breaking capacity, melting I²t value, and approval agency certifications. Any deviation in these parameters disqualifies a part from direct substitution.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 022401.5VXP and 022401.5HXP carry identical approvals (CE, CSA, PSE, UL) and maintain ROHS3 compliance. Regulatory and environmental compliance status is equivalent.

Q: What is the significance of the 2AG package specification?

A: The 2AG package designation specifies the physical form factor (5mm diameter x 15mm length axial cartridge) and establishes mechanical compatibility with standard fuse holders and PCB footprints designed for this package type. Substitutes must maintain this exact package specification to ensure proper mechanical fit and electrical contact.

Q: How does the melting I²t value affect substitution decisions?

A: The melting I²t value (0.8) defines the thermal energy required to melt the fuse element and is critical to the fuse's protective characteristics. Substitute parts must maintain identical I²t values to ensure equivalent response behavior and protection performance in the circuit.
