Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7010.9520.55 is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 8 A
• Voltage Rating (AC and DC): 65 V
• Response Time: Slow Blow
• Mounting Type: Surface Mount
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: 2-SMD, Square End Block
• Breaking Capacity @ Rated Voltage: 150 A
• Melting I²t: 83
• Operating Temperature Range: -55°C ~ 85°C
• Physical Dimensions: 0.276" L x 0.100" W x 0.100" H (7.00mm x 2.54mm x 2.54mm)

Parts meeting all these criteria are classified as direct equivalents and may be substituted without circuit redesign or thermal re-evaluation.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 7010.9520.57 is a direct electrical and mechanical equivalent to the 7010.9520.55. All critical fuse parameters—current rating, voltage ratings, response time, breaking capacity, melting I²t, and physical dimensions—are identical. Both components carry cURus certification and operate across the same temperature range.

The primary distinction is product status: the 7010.9520.55 is obsolete, while the 7010.9520.57 is active. The substitute part additionally carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment for new designs and production continuity.
