Littelfuse 0216.250HXP Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0216.250HXP is a ceramic cartridge fuse rated at 250 mA, 250 V AC/DC with fast-blow response characteristics. This component is designed for circuit protection in applications requiring reliable overcurrent interruption. The fuse operates within a temperature range of -55°C to 125°C and meets multiple international safety standards including CCC, CE, CSA, SEMKO, UR, and VDE certifications. As an active product with established supply availability, equivalent alternatives exist for applications requiring component substitution due to supply constraints or design flexibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed above maintain active product status and comply with RoHS3 requirements. The 0216.250HXP and 0216.250MXP are both Littelfuse products with identical electrical and mechanical specifications, differing only in packaging designation. Both hold certifications from CCC, CE, CSA, SEMKO, UR, and VDE.

The OptiFuse FCD-250MA provides parametric equivalence with identical current, voltage (AC), fuse type, response time, package dimensions, breaking capacity, and operating temperature range. The FCD-250MA additionally specifies 250 V DC rating and carries IEC 60127 certification. Selection between these parts should be based on supply availability, lead time requirements, and existing qualification status within the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the OptiFuse FCD-250MA be used as a direct replacement for the Littelfuse 0216.250HXP?

A: Yes. Both parts share identical electrical ratings (250 mA, 250 V AC), fuse type (ceramic cartridge), response time (fast blow), package dimensions (5mm x 20mm), breaking capacity (1.5 kA), and operating temperature range (-55°C to 125°C). Both require a fuse holder for mounting.

Q: What is the difference between the 0216.250HXP and 0216.250MXP?

A: These Littelfuse parts are electrically and mechanically identical. The designation difference reflects packaging or internal manufacturing variants. Both are active products with equivalent specifications and certifications.

Q: Are there any voltage rating differences between these substitutes?

A: The 0216.250HXP and 0216.250MXP specify 250 V AC rating. The OptiFuse FCD-250MA specifies both 250 V AC and 250 V DC ratings, providing additional DC application capability while maintaining AC equivalence.

Q: Do all three parts require the same holder?

A: Yes. All three parts use the 5mm x 20mm cartridge form factor and require a compatible fuse holder for installation.

Q: What certifications apply to these parts?

A: The Littelfuse 0216.250HXP and 0216.250MXP hold CCC, CE, CSA, SEMKO, UR, and VDE certifications. The OptiFuse FCD-250MA carries IEC 60127 certification. Verify certification requirements for your specific application before selection.
