0216.800MXEP Ceramic Fuse Cartridge - Equivalent & Substitute Parts

Part Overview

The 0216.800MXEP is an 800 mA ceramic fuse cartridge rated for 250 V AC/DC operation, manufactured by Littelfuse Inc. This fast-blow fuse is designed for through-hole mounting in 5mm x 20mm form factor applications. The part is currently active in production with 1654 units in stock. Equivalent substitute parts are necessary when primary sourcing is unavailable, when managing multi-supplier strategies, or when design flexibility permits component standardization across manufacturing facilities.

Substitute Part Grouping Explanation

Substitution eligibility for the 0216.800MXEP is determined by strict equivalence across the following critical parameters:

• Current Rating: 800 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Two substitute parts meet all substitution criteria: SCHURTER Inc. part number 0001.1003.PT and Bel Fuse Inc. part number 5HFP 800-R. Both components satisfy the mandatory electrical and mechanical parameters for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and REACH unaffected status. Selection among these equivalents should be based on the following factors:

Littelfuse 0216.800MXEP: Holds the broadest regulatory approval portfolio (CCC, CE, CSA, SEMKO, UL, VDE), making it suitable for applications requiring comprehensive international certification coverage. Lowest melting I²t value (0.285) indicates fastest thermal response.

SCHURTER 0001.1003.PT: Holds cURus certification. Highest melting I²t value (0.469) provides the slowest thermal response among the three options. Smallest diameter dimension (5.40mm) may be advantageous in space-constrained applications.

Bel Fuse 5HFP 800-R: Holds CCC, CE, CSA, and cULus certifications. Intermediate melting I²t value (0.36) and lowest DC cold resistance (0.206 Ohms) provide balanced thermal and electrical characteristics. Shortest axial length (21.00mm) may be beneficial in compact designs.

Frequently Asked Questions (FAQ)

Q: Can these parts be used interchangeably in all applications?

A: Yes, within the scope of the specified electrical and mechanical parameters. All three parts meet identical requirements for current rating (800 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (fast blow), package dimensions (5mm x 20mm axial), and breaking capacity (1.5 kA). Physical dimension variations are minor and should not affect standard through-hole mounting.

Q: What is the significance of the melting I²t difference?

A: Melting I²t is a thermal characteristic that defines the energy required to melt the fuse element. The 0216.800MXEP (0.285) will respond fastest to overcurrent conditions, while the 0001.1003.PT (0.469) will respond slowest. The 5HFP 800-R (0.36) provides intermediate response. Selection should align with circuit protection requirements.

Q: Are there regulatory compliance differences?

A: The 0216.800MXEP carries the most extensive approval portfolio (CCC, CE, CSA, SEMKO, UL, VDE). The 5HFP 800-R includes cULus certification. The 0001.1003.PT holds cURus certification. Verify that the selected part's certifications meet your application's regulatory requirements.

Q: Do physical dimension variations affect mounting?

A: All three parts are rated for 5mm x 20mm (Axial) package classification and through-hole mounting. Minor diameter and length variations (0.213" to 0.236" diameter; 0.827" to 0.886" length) are within standard tolerance ranges for ceramic fuse cartridges and should not impact standard fuse holder compatibility.

Q: Which part should I select for new designs?

A: Selection depends on your specific requirements. For maximum regulatory coverage, choose the 0216.800MXEP. For fastest thermal response, choose the 0216.800MXEP. For compact axial length, choose the 5HFP 800-R. For smallest diameter, choose the 0001.1003.PT. All are active products with adequate inventory.
