Frequently Asked Questions (FAQ)

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

A: Yes. All three part numbers are parametric equivalents with identical current ratings (2 A), voltage ratings (250 V AC / 125 V DC), fuse type (cartridge, glass), response time (slow blow), mounting configuration (through hole, axial), physical dimensions (0.177" Dia x 0.571" L), breaking capacity (35A AC, 10kA DC), and thermal characteristics. Direct substitution is supported.

Q: What determines substitution eligibility for this fuse cartridge?

A: Substitution is determined by equivalence across current rating, AC and DC voltage ratings, fuse type, response time, mounting type, package configuration, physical dimensions, breaking capacity, melting I²t value, DC cold resistance, and operating temperature range. All identified substitutes match these parameters exactly.

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

A: No. All three part numbers carry identical approval certifications (CE, CSA, PSE, UL) and RoHS3 compliance status, ensuring equivalent regulatory acceptance across all markets and applications.

Q: What is the significance of the part number suffix variations (MXP, HXP, HXSP)?

A: The suffix variations indicate different manufacturing or packaging batches within the Littelfuse 230 series. The suffixes do not reflect changes to electrical or mechanical specifications; all parts remain functionally equivalent.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. All three part numbers are rated for both AC (250 V) and DC (125 V) operation, with appropriate breaking capacity specifications for each voltage type (35A AC, 10kA DC).
