Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0617008.MXP is determined by strict equivalence across the following critical parameters:

• Current Rating: 8 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria. Variations in secondary parameters such as Breaking Capacity, Melting I²t, DC Cold Resistance, and approval agencies do not disqualify substitution but may influence selection based on application-specific requirements and regional compliance mandates.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection should be based on the following factors:

Littelfuse 0217008.HXP and 0217008.MXP: These parts offer expanded approval agency coverage (BSI, CCC, CSA, KC, PSE, SEMKO in addition to CE, UR, VDE) compared to the primary part. The 0217008.MXP variant provides the highest current inventory (4067 units). Both maintain identical electrical characteristics (Melting I²t: 198.16, DC Cold Resistance: 0.0068 Ohms, Breaking Capacity: 80A).

SCHURTER 0034.1525: This part provides equivalent electrical performance with a lower Melting I²t value (93.4 versus 198.16), indicating faster thermal response. Approval agencies include cURus, PSE/JET, and VDE. Highest inventory availability (5919 units).

OptiFuse FSD-8A: This part features a reduced Breaking Capacity (35A versus 80A) and lower Melting I²t (185.6). Approval coverage includes cURus and IEC 60127. Lowest inventory availability (1117 units).

Frequently Asked Questions (FAQ)

Q: Can I substitute the 0617008.MXP with any of these alternative parts?

A: Yes. All listed parts meet the critical substitution criteria: 8A current rating, 250V AC voltage rating, fast-blow response, 5x20mm package, and holder-based mounting. Electrical and thermal characteristics vary within acceptable ranges for this component category.

Q: What is the difference between Littelfuse 0617008.MXP and 0217008.MXP?

A: Both parts are manufactured by Littelfuse with identical electrical specifications (8A, 250V, Fast Blow, 5x20mm). The 0217008.MXP belongs to the 217 series and includes expanded approval agency certifications (BSI, CCC, CSA, KC, PSE, SEMKO). The 0617008.MXP belongs to the 617 series with CE, UR, VDE certifications.

Q: Why does the OptiFuse FSD-8A have a lower Breaking Capacity (35A)?

A: Breaking Capacity is a secondary parameter that does not disqualify substitution when all primary parameters (current, voltage, response time, package, mounting) are equivalent. The lower Breaking Capacity may be suitable for applications with lower fault current levels. Verify application requirements before selection.

Q: Which substitute part has the fastest thermal response?

A: The SCHURTER 0034.1525 has the lowest Melting I²t value (93.4), indicating the fastest thermal response among the listed substitutes. This may be advantageous in applications requiring rapid fault isolation.

Q: Are all these parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which part has the best availability?

A: The SCHURTER 0034.1525 has the highest inventory (5919 units), followed by the Littelfuse 0217008.MXP (4067 units).
