SCHURTER 7010.7090.49 Equivalent & Substitute Parts

Part Overview

The SCHURTER 7010.7090.49 is a 2A 125VAC board mount axial fuse designed for through-hole mounting applications. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and design requirements. The fuse features fast-blow response characteristics and is approved by CSA, GAM T1, and UR agencies. Due to its obsolete status, sourcing active alternatives with identical electrical and mechanical specifications is essential for system continuity and supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7010.7090.49 is determined by strict equivalence across the following critical parameters:

• Current Rating: 2 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 300A (exact match required)
• Melting I²t: 1.1 (exact match required)
• Operating Temperature Range: -55°C ~ 85°C (exact match required)
• Size / Dimension: 0.093" Dia x 0.315" L (2.36mm x 8.00mm) (exact match required)
• Approval Agency: CSA, GAM T1, UR (exact match required)

Substitute parts must maintain identical electrical performance, mechanical form factor, and regulatory compliance to ensure direct interchangeability in existing circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 7010.7090.47 is a direct equivalent substitute for the obsolete 7010.7090.49. Both components are manufactured by SCHURTER Inc. within the same 172322 series and share identical electrical ratings, mechanical dimensions, and regulatory approvals.

The primary distinction is product status: the 7010.7090.49 is obsolete, while the 7010.7090.47 maintains active status with current inventory availability (671 pieces in stock). The substitute part provides additional compliance documentation, including ROHS3 certification and REACH unaffected status, which may be required for new designs or regulatory submissions.

All critical parameters—current rating, voltage rating, mounting configuration, response time, breaking capacity, thermal characteristics, and physical dimensions—are identical between the two parts. The substitute part is suitable for direct replacement in existing designs without circuit modification or PCB layout changes.

Frequently Asked Questions (FAQ)

Q: Can the 7010.7090.47 be used as a direct replacement for the 7010.7090.49?
