Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 3-103-116 is determined by strict equivalence across the following critical parameters:

• Current Rating: 2 A (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 @ Rated Voltage: 50A AC, 300A DC (exact match required)
• Size / Dimension: 0.126" L x 0.061" W x 0.061" H (exact match required)
• Manufacturer: SCHURTER Inc. (same manufacturer)
• RoHS Status: ROHS3 Compliant (compliance requirement)

Two substitute parts meet these criteria: SCHURTER 3410.0035.03 (Upgrade designation) and SCHURTER 3-103-115 (Parametric Equivalent). Both parts maintain identical electrical and mechanical specifications with the main part number 3-103-116.

Parameter Comparison

Engineering Selection Recommendations

All three parts—3-103-116, 3410.0035.03, and 3-103-115—are Active status components manufactured by SCHURTER Inc. and maintain ROHS3 compliance. Selection between these parts is based on specific application requirements and packaging constraints:

3-103-116 (Main Part): Provides dual certification (cURus and UL) with Tape & Reel packaging. Operating temperature range extends to 125°C. Suitable for applications requiring UL certification.

3410.0035.03 (Upgrade Designation): Extends operating temperature range to 150°C, supporting higher thermal environments. Certified by cURus. Supplied in Tape & Reel packaging. This part represents an upgraded thermal specification while maintaining all other electrical and mechanical parameters.

3-103-115 (Parametric Equivalent): Maintains identical electrical and thermal specifications to the main part (125°C maximum). Dual certification (cURus and UL) equivalent to 3-103-116. Supplied in Cut Tape packaging, suitable for lower-volume or manual assembly operations.

Frequently Asked Questions (FAQ)

Q: Can 3410.0035.03 be used as a direct replacement for 3-103-116?

A: Yes. Both parts share identical current rating (2A), voltage ratings (125V AC/DC), response time (Fast Blow), mounting type (Surface Mount), package configuration (2-SMD Square End Block), breaking capacity (50A AC, 300A DC), and physical dimensions. The 3410.0035.03 provides an extended operating temperature range (-55°C to 150°C versus -55°C to 125°C), making it suitable for higher thermal applications. Approval agency certification differs (3410.0035.03 carries cURus only, while 3-103-116 carries cURus and UL).

Q: What is the difference between 3-103-115 and 3-103-116?

A: These parts are parametric equivalents with identical electrical specifications and operating temperature range. The primary difference is packaging: 3-103-116 is supplied in Tape & Reel (TR) format, while 3-103-115 is supplied in Cut Tape (CT) format. Both carry cURus and UL certifications. Selection depends on assembly process requirements and volume considerations.

Q: Which part should be selected for high-temperature applications?

A: The SCHURTER 3410.0035.03 is specified for operating temperatures up to 150°C, compared to 125°C for both 3-103-116 and 3-103-115. This part is appropriate for applications requiring extended thermal performance within the specified current and voltage ratings.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts—3-103-116, 3410.0035.03, and 3-103-115—are ROHS3 Compliant.

Q: What packaging options are available?

A: The 3-103-116 and 3410.0035.03 are supplied in Tape & Reel (TR) packaging for automated assembly. The 3-103-115 is supplied in Cut Tape (CT) packaging, suitable for manual or lower-volume assembly processes.
