Engineering Selection Recommendations

All three substitute parts maintain active product status and carry identical regulatory approvals (CE, CSA, PSE, UL) with full ROHS3 compliance. Selection among 0230002.HXP, 0230002.HXSP, and 0230002.MXP is based on inventory availability and supply chain requirements, as all parts are electrically and mechanically equivalent to the 0230002.VXSP.

The 0230002.MXP variant offers the highest inventory availability (34,412 pcs), followed by 0230002.HXP (3,311 pcs) and 0230002.HXSP (1,279 pcs). The original 0230002.VXSP maintains 786 pcs in stock. All parts are supplied in bulk packaging by Littelfuse Inc. and are suitable for immediate integration into circuit protection applications without design modification.

Frequently Asked Questions (FAQ)

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

A: Yes. All three substitute parts meet identical electrical specifications (2 A, 250 V AC, 125 V DC), mechanical dimensions (0.177" Dia x 0.571" L), and performance characteristics (Slow Blow response, 30 Melting I²t). They are direct functional equivalents for circuit protection applications.

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

A: The 0230002.VXSP specifies 100A AC breaking capacity, while 0230002.HXP, 0230002.HXSP, and 0230002.MXP specify 35A AC breaking capacity. Both ratings are provided in the component specifications and should be evaluated against application requirements.
