SCHURTER 3101.0075 Cartridge Fuse Holder 16A 400V PCB Mount

Part Overview

The SCHURTER 3101.0075 is a 16 ampere, 400 volt cartridge fuse holder designed for single-circuit applications with 5mm x 20mm fuse compatibility. This component features surface mount (gull wing) termination and is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3101.0075 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 16 A (must match exactly)
• Voltage Rating: 400V (must match exactly)
• Fuse Size: 5mm x 20mm (must match exactly)
• Number of Circuits: 1 (must match exactly)
• Contact Material and Finish: Copper Alloy with Tin finish (must match)
• Compliance: ROHS3 Compliant, REACH Unaffected (must maintain)

The primary distinction between the main part and its substitute relates to mounting technology: the 3101.0075 uses surface mount (gull wing) termination, while alternatives may employ through-hole (PC pin) termination. This difference affects PCB layout and assembly process but does not alter electrical performance or fuse compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3101.0050 serves as a direct electrical equivalent to the 3101.0075, maintaining identical current rating, voltage rating, fuse size, and circuit count. Both components are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

The 3101.0050 holds active product status with significantly higher inventory availability (5051 pieces versus 861 pieces), making it the preferred choice for new designs and production continuity. The transition from surface mount to through-hole mounting requires PCB layout modification but does not compromise electrical performance or safety characteristics.

Selection between these parts depends on PCB assembly technology: surface mount assembly requires the 3101.0075 (or equivalent surface mount alternatives), while through-hole assembly accommodates the 3101.0050.

Frequently Asked Questions (FAQ)

Q: Can the 3101.0050 replace the 3101.0075 in existing designs?

A: Electrical replacement is direct. PCB layout and assembly process must be modified to accommodate the transition from gull wing (surface mount) to PC pin (through-hole) termination.

Q: Are the electrical specifications identical between these parts?

A: Yes. Current rating (16 A), voltage rating (400V), fuse size (5mm x 20mm), circuit count (1), contact material, and contact finish are identical. Both accept the same 5mm x 20mm cartridge fuses.

Q: What is the impact of the mounting type difference?

A: Mounting type affects PCB design and assembly method only. Electrical performance, fuse compatibility, and safety ratings remain unchanged.

Q: Are both parts compliant with current regulations?

A: Yes. Both the 3101.0075 and 3101.0050 are ROHS3 compliant and REACH unaffected.

Q: Why is the 3101.0050 recommended despite being a different series?

A: The 3101.0050 (FPG5 series) maintains all critical electrical and mechanical parameters required for substitution. Its active product status and higher inventory availability support production continuity and design flexibility.
