SCHURTER 0034.4247 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.4247 is a board mount fuse rated for 630 mA at 125 V AC/DC with fast blow response characteristics. This component is designed for through-hole radial mounting in cylindrical can package format. The part maintains active product status with full cURus approval agency certification and ROHS3 compliance. Substitute parts are identified when identical electrical ratings, mechanical mounting specifications, and approval certifications are maintained across alternative part numbers within the same manufacturer series.

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0034.4247 is determined by strict equivalence across the following critical parameters:

• Current Rating: 630 mA (exact match required)
• Voltage Rating: 125 V AC and 125 V DC (both required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount, Cartridge Style Excluded (exact match required)
• Package / Case: Radial, Can (exact match required)
• Breaking Capacity: 100 A @ Rated Voltage (exact match required)
• Melting I²t: 0.045 (exact match required)
• Operating Temperature Range: -25°C to 85°C (exact match required)
• Physical Dimensions: 0.252" Dia x 0.346" H / 6.40 mm x 8.80 mm (exact match required)
• Series: MSF 125 (exact match required)
• Approval Certifications: cURus (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The SCHURTER 0034.4217 meets all substitution criteria as a parametric equivalent within the MSF 125 series.

Frequently Asked Questions (FAQ)

Q: Can the 0034.4217 be used as a direct replacement for the 0034.4247?

A: Yes. Both parts are parametric equivalents with identical current ratings, voltage ratings, response characteristics, mounting specifications, physical dimensions, and approval certifications. Direct substitution is supported without circuit modification.

Q: What determines if a fuse can substitute for the 0034.4247?

A: Substitute fuses must match all critical parameters: 630 mA current rating, 125 V AC/DC voltage rating, fast blow response, through-hole radial mounting, board mount package type, 100 A breaking capacity, 0.045 melting I²t value, -25°C to 85°C operating temperature range, 6.40 mm x 8.80 mm physical dimensions, MSF 125 series designation, cURus certification, and ROHS3 compliance status.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both the 0034.4247 and 0034.4217 share identical dimensions of 0.252" diameter by 0.346" height (6.40 mm x 8.80 mm). PCB footprint compatibility is maintained.

Q: Do both parts have the same approval certifications?

A: Yes. Both parts carry cURus approval agency certification and maintain ROHS3 compliance status, confirming regulatory acceptance for equivalent applications.

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

A: Melting I²t of 0.045 defines the thermal energy required to melt the fuse element. This parameter must match exactly between substitute parts to ensure identical circuit protection response characteristics and prevent nuisance trips or delayed protection.
