Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 7010.9515.55 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Current Rating: 3.15 A (exact match required)
• Voltage Rating: 125 V AC and 125 V DC (both required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 2-SMD, Square End Block (exact match required)
• Breaking Capacity @ Rated Voltage: 150 A (exact match required)
• Melting I²t: 12 (exact match required)
• Operating Temperature Range: -55°C ~ 85°C (exact match required)
• Physical Dimensions: 0.276" L x 0.100" W x 0.100" H (exact match required)

Only parts meeting all specified parameters are classified as direct substitutes. Compliance certifications and product status are secondary considerations that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 7010.9515.57 is a direct electrical and mechanical equivalent to the obsolete 7010.9515.55. Both components are manufactured by SCHURTER Inc. within the MKT series and share identical specifications across all critical parameters: current rating, voltage ratings, response time, mounting configuration, package type, breaking capacity, thermal characteristics, and physical dimensions.

The primary distinction between these parts is product status: the 7010.9515.55 is obsolete, while the 7010.9515.57 maintains active production status. Both parts carry cURus approval certification and are suitable for applications requiring 3.15 A slow-blow protection at 125 V AC/DC in surface mount configurations.

For new designs or production continuity, the 7010.9515.57 is the appropriate selection due to its active availability and identical functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 7010.9515.57 be used as a direct replacement for the 7010.9515.55 in existing designs?

A: Yes. The 7010.9515.57 is electrically and mechanically identical to the 7010.9515.55 across all specified parameters, including current rating, voltage ratings, response time, package type, and physical dimensions. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The 7010.9515.55 is classified as obsolete, while the 7010.9515.57 is in active production. All electrical and mechanical specifications are identical.

Q: Are both parts certified by the same approval agency?

A: Yes. Both the 7010.9515.55 and 7010.9515.57 carry cURus approval certification.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by exact equivalence in current rating (3.15 A), voltage ratings (125 V AC/DC), response time (Slow Blow), mounting type (Surface Mount), package configuration (2-SMD, Square End Block), breaking capacity (150 A), melting I²t (12), operating temperature range (-55°C ~ 85°C), and physical dimensions (0.276" L x 0.100" W x 0.100" H).

Q: Can these fuses be used in applications requiring different current ratings?

A: No. These components are rated specifically for 3.15 A protection. Use of these fuses in applications requiring different current ratings will result in improper circuit protection.

Q: Are there any compliance differences between the two parts?

A: Both parts meet cURus certification requirements. The 7010.9515.57 includes additional compliance documentation (RoHS3 Compliant, REACH Unaffected status), which reflects its active production status but does not affect electrical or mechanical compatibility.
