Littelfuse 0216.800MXP Ceramic Fuse 800mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0216.800MXP is an 800 mA, 250 V AC/DC ceramic cartridge fuse in a 5mm x 20mm package form factor. This fast-blow fuse requires a compatible holder for installation and is designed for circuit protection applications requiring rapid response to overcurrent conditions. The part maintains active product status with full compliance to international safety standards including UL, CE, CSA, VDE, and CCC certifications. Equivalent and substitute parts are identified when identical electrical ratings, mechanical dimensions, and performance characteristics are maintained across different manufacturers.

Substitute Part Grouping Explanation

Substitution of ceramic cartridge fuses is determined by strict equivalence of electrical and mechanical parameters. All substitute parts listed maintain identical current ratings (800 mA), AC voltage ratings (250 V), fuse type (ceramic cartridge), response time (fast blow), and physical dimensions (5mm x 20mm). Breaking capacity at rated voltage is held constant at 1.5 kA across all listed alternatives. Operating temperature range remains -55°C to 125°C for all parts except GDA-800MA, where operating temperature is not specified in available data. All parts require compatible fuse holders and are manufactured by recognized component suppliers with active product status.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and are manufactured by established component suppliers. Selection among equivalent parts should be based on certification requirements specific to the application. The 0216.800MXP and 0216.800HXP are both Littelfuse products with identical electrical and mechanical specifications, differing only in internal construction characteristics. The SCHURTER 0001.1003 carries VDE, cURus, and KC certifications. The Eaton GDA-800MA series carries CSA, IMQ, SEMKO, and UR certifications. The OptiFuse FCD-800MA is certified to IEC 60127 and carries ROHS3 compliance with MSL rating of 1 (Unlimited). All parts are RoHS3 compliant where specified and carry ECCN classification EAR99. Inventory availability varies across manufacturers, with OptiFuse FCD-800MA showing the highest stock level at 4,157 pieces.

Frequently Asked Questions (FAQ)

Q: Can the 0216.800HXP be used as a direct replacement for the 0216.800MXP?

A: Yes. Both parts are manufactured by Littelfuse, maintain identical electrical ratings (800 mA, 250 V AC), ceramic cartridge construction, fast-blow response, 5mm x 20mm dimensions, and 1.5 kA breaking capacity. Both require compatible fuse holders and operate across the -55°C to 125°C temperature range.

Q: What is the difference between the Littelfuse and SCHURTER 800 mA fuses?

A: The primary difference is manufacturer and certification profile. Both maintain identical current, voltage, fuse type, response time, and package specifications. The SCHURTER 0001.1003 has a higher melting I²t value (0.469 versus 0.285), indicating different internal element characteristics. Certification agencies differ: Littelfuse carries UL, CE, CSA, SEMKO, VDE, and CCC; SCHURTER carries VDE, cURus, and KC.

Q: Is the OptiFuse FCD-800MA compatible with the same holders as the Littelfuse 0216.800MXP?

A: Yes. The FCD-800MA maintains the identical 5mm x 20mm package dimensions and cartridge ceramic construction, requiring the same holder type. All electrical ratings (800 mA, 250 V AC, 1.5 kA breaking capacity, fast-blow response) are equivalent.

Q: What does the melting I²t value indicate?

A: Melting I²t is a thermal characteristic that describes the fuse element's response to overcurrent. Different I²t values indicate variations in internal construction and thermal mass. All listed parts maintain the same current rating and breaking capacity, but I²t differences may affect response characteristics in specific circuit conditions.

Q: Are all substitute parts RoHS3 compliant?

A: RoHS3 compliance is confirmed for the Littelfuse 0216.800MXP, 0216.800HXP, SCHURTER 0001.1003, and OptiFuse FCD-800MA. The Eaton GDA-800MA RoHS status is not specified in available data.
