Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 2030.0024 is determined by strict equivalence across the following critical parameters:

• Current Rating: 2A (exact match required)
• Voltage Rating: 125 VAC / 125 VDC (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: Radial, Can (exact match required)
• Size / Dimension: 0.252" Dia x 0.346" (6.40mm x 8.80mm) (exact match required)
• Breaking Capacity: 100A (exact match required)
• Melting I²t: 0.43 (exact match required)
• Operating Temperature Range: -25°C ~ 85°C (exact match required)
• Approval Agency: cURus (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The SCHURTER 0034.4224 meets all substitution criteria as an active product within the MSF 125 series.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.4224 be used as a direct replacement for the 2030.0024 in existing designs?

A: Yes. The 0034.4224 is electrically and mechanically equivalent. All critical parameters including current rating, voltage rating, response time, package dimensions, and breaking capacity are identical. Through-hole mounting compatibility allows direct PCB substitution.

Q: What is the difference between the MSU 125 series (2030.0024) and MSF 125 series (0034.4224)?

A: Both series are SCHURTER board mount fuses with identical electrical and mechanical specifications for this current and voltage rating. The MSF 125 series is the active production line, while the MSU 125 series is obsolete.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts measure 0.252" diameter x 0.346" length (6.40mm x 8.80mm) in radial, can configuration, ensuring identical through-hole PCB footprints.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 2030.0024 and 0034.4224 carry cURus approval, are ROHS3 compliant, and are REACH unaffected, meeting identical regulatory requirements for telecom applications.

Q: What is the melting I²t specification and why is it important?

A: The melting I²t value of 0.43 defines the thermal energy required to melt the fuse element. Identical I²t values ensure equivalent circuit protection characteristics and response behavior under fault conditions.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. Both parts are rated for 125 VAC and 125 VDC operation, enabling use in mixed AC/DC telecom power distribution systems.
