Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 3-103-088 are qualified based on the following electrical and mechanical parameters:

• Current Rating: 200 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)
• Breaking Capacity: 50 A AC, 300 A DC (exact match required)
• Physical Dimensions: 0.126" L x 0.061" W x 0.061" H (exact match required)

The substitute parts 3410.0021.02 and 3410.0021.03 meet all critical electrical and mechanical parameters. Both parts are manufactured by SCHURTER Inc., share identical current, voltage, and breaking capacity ratings, and are packaged in the same 2-SMD square end block configuration with matching physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 3410.0021.02 and 3410.0021.03 are qualified replacements for the SCHURTER 3-103-088 based on electrical and mechanical equivalence. All three parts maintain Active product status and ROHS3 compliance. The substitute parts feature an extended operating temperature range of -55°C to 150°C compared to the main part's -55°C to 125°C range, providing additional thermal margin in applications requiring higher temperature operation. Both substitute parts carry cURus certification; the main part includes additional UL certification. Selection between the main part and substitutes should be based on inventory availability, supply chain requirements, and specific application temperature operating conditions.

Frequently Asked Questions (FAQ)

Q: Are parts 3410.0021.02 and 3410.0021.03 direct replacements for 3-103-088?

A: Yes. Both substitute parts meet all critical electrical specifications (200 mA, 125 V AC/DC, Fast Blow response) and mechanical requirements (2-SMD square end block package, identical physical dimensions, 50 A AC / 300 A DC breaking capacity). All three parts are manufactured by SCHURTER Inc. and are ROHS3 compliant.

Q: What is the difference between the main part and the substitute parts?

A: The substitute parts 3410.0021.02 and 3410.0021.03 feature an extended operating temperature range of -55°C to 150°C compared to the main part's -55°C to 125°C. The main part includes both cURus and UL certifications, while the substitute parts carry cURus certification.

Q: Can I use 3410.0021.02 and 3410.0021.03 interchangeably?

A: Yes. Both substitute parts are electrically and mechanically identical and can be used interchangeably in applications requiring the 200 mA, 125 V AC/DC surface mount fuse specification.

Q: Are there any package or footprint differences between these parts?

A: No. All three parts use the same 2-SMD square end block package with identical physical dimensions of 0.126" L x 0.061" W x 0.061" H (3.20mm x 1.55mm x 1.55mm). PCB footprints are identical.

Q: What certifications apply to each part?

A: The main part 3-103-088 carries cURus and UL approvals. Substitute parts 3410.0021.02 and 3410.0021.03 carry cURus approval. Application requirements should determine which certification level is necessary.
