Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0217.200MXP is determined by the following critical parameters:

Primary Matching Criteria:

• Current Rating: 200 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Package Dimensions: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)

Secondary Compatibility Factors:

• Breaking Capacity: 35A minimum
• Operating Temperature: -55°C to 125°C range
• Mounting: Requires Holder (mechanical compatibility)
• RoHS Compliance: ROHS3 Compliant

All identified substitute parts meet these primary criteria. Variations in melting I²t values, DC cold resistance, and specific approval agency certifications do not affect functional substitutability within the defined electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse Series 217 (0217.200MXP, 0217.200HXP, 0217.200TXP): These three Littelfuse parts are parametrically equivalent with identical electrical and mechanical specifications. Selection among them is based on product availability and approval agency requirements. The 0217.200MXP carries approvals from CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. The 0217.200TXP includes KC and UR certifications in place of K-MARK and CSA. All three maintain active product status.

Littelfuse Series 235 (0235.200HXP): This part meets all primary substitution criteria with identical current, voltage, package, and response characteristics. It differs in melting I²t (0.00867 versus 0.02) and DC cold resistance (3.15 Ohms versus 1.7 Ohms). Approval agencies include CE, CSA, KC, and UL. This part is suitable for applications where the Series 235 characteristics are acceptable.

SCHURTER 0034.1509 (FSF 5x20 Series): This cross-manufacturer substitute from SCHURTER meets all primary electrical and mechanical parameters. It carries CCC, cURus, and VDE certifications. The melting I²t value is 0.0252, and DC cold resistance is not specified. This part provides an alternative source from a different manufacturer.

OptiFuse FSD-200MA (FSD Series): This OptiFuse part satisfies all primary substitution requirements with matching current, voltage, package, and response specifications. It carries cURus and IEC 60127 approvals. The melting I²t is 0.0256. This part offers supply diversification from a third manufacturer.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 0217.200MXP with any of the listed equivalent parts? A: Yes. All listed parts meet the critical electrical parameters (200mA, 250VAC), mechanical dimensions (5mm x 20mm), response time (fast blow), and breaking capacity (35A). They are functionally interchangeable in circuit protection applications.

Q: What is the difference between the Littelfuse Series 217 variants (0217.200MXP, 0217.200HXP, 0217.200TXP)? A: These three parts are parametrically identical in electrical and mechanical specifications. Differences exist only in approval agency certifications. Selection should be based on the specific regulatory requirements of your application and regional compliance needs.

Q: Why does the 0235.200HXP have different melting I²t and DC cold resistance values? A: The Series 235 is a different product line within Littelfuse. While it meets all primary substitution criteria for current, voltage, package, and response time, the internal construction differs, resulting in different thermal and resistance characteristics. It remains functionally equivalent for the specified electrical parameters.

Q: Can I use the SCHURTER 0034.1509 or OptiFuse FSD-200MA as direct replacements? A: Yes. Both parts meet all primary electrical and mechanical requirements. They provide cross-manufacturer alternatives when Littelfuse parts are unavailable. Verify that the approval certifications (CCC, cURus, VDE for SCHURTER; cURus, IEC 60127 for OptiFuse) satisfy your application's compliance requirements.

Q: Does the fuse holder compatibility differ between manufacturers? A: No. All parts use the standard 5mm x 20mm cartridge form factor and require a compatible holder. Any standard 5x20mm fuse holder will accommodate any of these parts.

Q: What should I consider when selecting between these substitutes? A: Primary considerations are product availability, approval agency certifications required by your application, and supply chain reliability. All parts are electrically and mechanically equivalent for the specified 200mA, 250VAC, fast-blow application.
