SCHURTER 3-103-095 Equivalent & Substitute Parts

Part Overview

The SCHURTER 3-103-095 is a 375 mA surface mount board mount fuse rated for 125 V AC/DC operation. This fast blow fuse is designed for SMD applications with a 2-SMD square end block package configuration. The part is currently active in production and widely stocked, with 3,724 units available in cut tape packaging. Substitute parts are identified to provide alternative sourcing options with equivalent electrical and mechanical specifications, particularly for applications requiring different packaging formats or extended operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 3-103-095 are qualified based on the following electrical and mechanical parameters:

• Current Rating: 375 mA (exact match required)
• Voltage Rating: 125 V AC and 125 V DC (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 2-SMD, Square End Block (exact match required)
• Physical Dimensions: 0.126" L × 0.061" W × 0.061" H (exact match required)
• Breaking Capacity: 50 A AC / 300 A DC (exact match required)

The identified substitutes (3410.0025.02 and 3410.0025.03) meet all core electrical and mechanical requirements. Differences exist in packaging format (tape & reel versus cut tape), series designation (MGA versus MGA-A), operating temperature range extension, and melting I²t characteristics. These variations do not affect functional equivalence for standard board mount fuse applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—3-103-095, 3410.0025.02, and 3410.0025.03—are active production components from SCHURTER Inc. with ROHS3 compliance and equivalent electrical performance for 375 mA, 125 V AC/DC fast blow fuse applications.

3-103-095 is supplied in cut tape packaging and carries dual approval (cURus and UL) with an operating temperature range of -55°C to 125°C.

3410.0025.02 and 3410.0025.03 are supplied in tape & reel packaging with cURus approval and an extended operating temperature range of -55°C to 150°C. These parts are functionally interchangeable with the main part number for standard board mount fuse applications where the extended temperature rating and tape & reel format are acceptable.

Selection between these substitutes depends on packaging requirements (cut tape versus tape & reel) and whether the extended operating temperature range (-55°C to 150°C) is required for the application.

Frequently Asked Questions (FAQ)

Q: Are parts 3410.0025.02 and 3410.0025.03 electrically equivalent to 3-103-095?

A: Yes. All three parts share identical current ratings (375 mA), voltage ratings (125 V AC/DC), response time (fast blow), breaking capacity (50 A AC / 300 A DC), and physical dimensions (0.126" L × 0.061" W × 0.061" H). They are electrically equivalent for board mount fuse applications.

Q: What is the difference between the main part and the substitutes?

A: The primary differences are packaging format (cut tape versus tape & reel), operating temperature range (125°C maximum versus 150°C maximum), and approval agencies (dual cURus/UL versus cURus only). Electrical and mechanical specifications are identical.

Q: Can I use 3410.0025.02 or 3410.0025.03 in place of 3-103-095 on my PCB?

A: Yes, provided your application does not require the specific approval combination (cURus and UL) of the original part. Both substitutes are cURus approved and have identical package dimensions and electrical ratings.

Q: Why do the substitute parts have different melting I²t values?

A: The melting I²t values provided (0.00035 for 3-103-095 versus 0.0037 for 3410.0025.02 and 3410.0025.03) reflect measured thermal characteristics. Despite this difference, all parts maintain the same 375 mA current rating and fast blow response time classification.

Q: Which part should I select for high-temperature applications?

A: For applications requiring operation above 125°C, select 3410.0025.02 or 3410.0025.03, which are rated to 150°C maximum. The main part 3-103-095 is limited to 125°C.

Q: Are there any compatibility issues with tape & reel packaging?

A: No. Tape & reel packaging (used for 3410.0025.02 and 3410.0025.03) is standard for automated assembly processes. The physical component dimensions and electrical specifications remain unchanged. Compatibility depends on your assembly equipment and process requirements, not on the component itself.
