Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 0034.4258 and 0034.4228 are active products with identical electrical specifications, mechanical form factors, and regulatory compliance. Selection between these parts should be based on inventory availability and lead time requirements. Both parts carry cURus approval and ROHS3 compliance, ensuring regulatory alignment for applications requiring these certifications. The 0034.4228 maintains higher inventory levels (5734 Pcs vs. 685 Pcs), which may influence procurement decisions for high-volume or time-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the 0034.4228 be used as a direct replacement for the 0034.4258?

A: Yes. Both parts are parametric equivalents within the MSF 125 series, sharing identical current ratings (5A), voltage ratings (125VAC/VDC), response time (Fast Blow), package type (Radial, Can), breaking capacity (100A), melting I²t (3), operating temperature range (-25°C ~ 85°C), and physical dimensions (0.252" Dia x 0.346" H). Both are through-hole board mount fuses with cURus approval and ROHS3 compliance.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. Both parts use identical through-hole radial can packaging with matching physical dimensions (6.40mm x 8.80mm). PCB footprints and mounting requirements are identical.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 0034.4258 and 0034.4228 carry cURus approval and are ROHS3 compliant. REACH status is unaffected for both parts, and both are classified under ECCN EAR99 and HTSUS 8536.10.0040.

Q: What is the difference between these two part numbers?

A: The parts are electrically and mechanically identical. The difference lies in inventory availability and manufacturing batch designation. The 0034.4228 has significantly higher stock levels, making it preferable for applications requiring immediate availability.

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

A: Yes. Both parts are rated for 125VAC and 125VDC operation, supporting dual-voltage applications within the specified voltage range.
