Littelfuse 0218.200MXEP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218.200MXEP is a 200 mA, 250 V AC/DC slow-blow glass cartridge fuse with through-hole mounting in a 5mm x 20mm axial package. This component is classified as Active product status and is designed for circuit protection applications requiring reliable overcurrent interruption. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 0218.200MXEP is determined by strict equivalence across the following parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The following parts meet all substitution criteria:

• SCHURTER Inc. 0034.3110.PT (FST 5x20 Series)
• Bel Fuse Inc. 5STP 200-R (5STP Series)

Parameter Comparison

Engineering Selection Recommendations

All three parts—Littelfuse 0218.200MXEP, SCHURTER 0034.3110.PT, and Bel Fuse 5STP 200-R—are Active product status and ROHS3 compliant. Selection among these equivalents should be based on:

• Approval agency certifications required for the application (UL, CE, CSA, VDE, etc.)
• Physical dimension tolerance requirements, as minor variations exist in diameter and length
• DC cold resistance specifications if relevant to circuit design
• Melting I²t characteristics if thermal response precision is critical
• Inventory availability and lead time

The Littelfuse 0218.200MXEP carries the broadest certification portfolio (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE), making it suitable for applications with multiple regulatory requirements. The SCHURTER 0034.3110.PT and Bel Fuse 5STP 200-R are direct functional equivalents with overlapping but distinct certification coverage.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 0034.3110.PT be used as a direct replacement for Littelfuse 0218.200MXEP?

A: Yes. Both parts meet identical electrical specifications (200 mA, 250 V AC, slow-blow response, 35 A breaking capacity) and mechanical requirements (5mm x 20mm axial through-hole package, -55°C to 125°C operating range, ROHS3 compliance). Minor dimensional variations exist (diameter: 5.40mm vs. 5.80mm; length: 22.50mm for both), which are within standard cartridge fuse tolerances for through-hole mounting.

Q: Can Bel Fuse 5STP 200-R be used as a direct replacement for Littelfuse 0218.200MXEP?

A: Yes. The 5STP 200-R meets all electrical and mechanical substitution criteria. Physical dimensions differ slightly (diameter: 5.50mm vs. 5.80mm; length: 21.00mm vs. 22.50mm), which remain compatible with standard 5x20mm fuse holders. Verify holder specifications if dimensional tolerance is critical.

Q: What are the key differences between these three parts?

A: All three parts are electrically and functionally equivalent. Differences are limited to: manufacturer certifications (Littelfuse carries the most comprehensive agency approvals), physical dimensions (minor variations within standard tolerances), melting I²t values (0.341 for Littelfuse, 0.256 for SCHURTER, 0.15 for Bel Fuse), and DC cold resistance (1.6 Ohms for Littelfuse, 2.9 Ohms for Bel Fuse, not specified for SCHURTER).

Q: Are there any compatibility concerns with PCB-mounted fuse holders?

A: All three parts use identical 5mm x 20mm axial through-hole packages and are compatible with standard fuse holders designed for this form factor. Minor dimensional variations do not affect mechanical fit in standard holders.

Q: Which part should I select if multiple certifications are required?

A: The Littelfuse 0218.200MXEP carries certifications from CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. The Bel Fuse 5STP 200-R carries CCC, CE, CSA, cULus, IMQ, SEMKO, and VDE certifications. The SCHURTER 0034.3110.PT carries cURus certification. Verify which certifications your application requires before selection.
