Engineering Selection Recommendations

All substitute parts maintain active product status and carry identical regulatory approvals (CE, CSA, PSE, UL). Selection among 0230002.VXP, 0230002.HXP, 0230002.HXSP, and 0230002.MXP should be based on inventory availability and supply chain requirements. The 0230002.MXP variant offers the highest inventory level (34,412 pcs), followed by 0230002.HXP (3,311 pcs) and 0230002.HXSP (1,279 pcs), while the primary part 0230002.VXP maintains 633 pcs in stock. All parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can 0230002.HXP, 0230002.HXSP, and 0230002.MXP be used interchangeably with 0230002.VXP?

A: Yes. All substitute parts are parametric equivalents with identical electrical ratings (2 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 thermal characteristics. They are suitable for direct substitution in circuit protection applications.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is based on exact matching of current rating, voltage ratings (AC and DC), fuse type, response time, mounting type, package configuration, physical dimensions, operating temperature range, melting I²t, DC cold resistance, RoHS compliance status, and regulatory approvals. All listed substitutes meet these criteria.

Q: Are there differences in breaking capacity between the main part and substitutes?

A: The main part 0230002.VXP specifies 100A AC breaking capacity, while substitute parts 0230002.HXP, 0230002.HXSP, and 0230002.MXP specify 35A AC breaking capacity. Both meet the DC breaking capacity of 10kA. Application requirements should determine which breaking capacity specification is appropriate.

Q: Do all parts carry the same regulatory approvals?

A: Yes. The main part and all substitute parts carry CE, CSA, PSE, and UL approvals, ensuring compliance with international safety standards for circuit protection devices.

Q: What is the difference between the part number suffixes (VXP, HXP, HXSP, MXP)?

A: The suffixes denote different manufacturing variants within the Littelfuse 230 series. All variants maintain identical electrical and mechanical specifications for the 2 A, 250 V AC / 125 V DC cartridge fuse configuration.
