SCHURTER 0070.3561.T2 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0070.3561.T2 is a 56 V, 2 kA Transient Voltage Suppressor (TVS) varistor in a through-hole disc package (14mm). This component is designed for transient voltage protection in electronic circuits. The part is currently obsolete, making equivalent substitute parts necessary for ongoing design support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 0070.3561.T2 is determined by the following critical electrical and mechanical parameters:

• Varistor voltage rating: 56 V (typical), with acceptable range 50 V to 62 V
• Surge current capacity: 2 kA minimum
• Energy dissipation: 16 J
• Number of circuits: 1
• Mounting configuration: Through hole
• Maximum AC/DC voltage ratings: 35 V AC / 45 V DC
• RoHS3 compliance and REACH unaffected status

The Panasonic ERZ-V14D560 meets all critical electrical parameters and maintains through-hole mounting compatibility, qualifying it as a direct substitute despite minor package dimension variation (15.5mm vs. 14mm disc diameter).

Parameter Comparison

Engineering Selection Recommendations

The Panasonic ERZ-V14D560 is the qualified substitute for the obsolete SCHURTER 0070.3561.T2. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for current applications.

The ERZ-V14D560 maintains active product status with established supply availability, eliminating sourcing constraints associated with the obsolete SCHURTER part. All critical electrical parameters—varistor voltage, surge current, energy dissipation, and circuit count—are identical between the two components.

The operating temperature range of the Panasonic part (-40°C ~ 85°C) is narrower than the SCHURTER original (-40°C ~ 125°C). Applications requiring operation above 85°C require thermal performance verification. The package diameter increase (15.5mm vs. 14mm) requires PCB layout confirmation for mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic ERZ-V14D560 directly replace the SCHURTER 0070.3561.T2?

A: Yes, the ERZ-V14D560 is electrically equivalent. Both components have identical varistor voltage ratings (56 V typical), surge current capacity (2 kA), and energy dissipation (16 J). Both are through-hole mounted and ROHS3 compliant. PCB layout verification is required due to the 1.5mm increase in disc diameter.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) operating temperature range—SCHURTER supports -40°C to 125°C while Panasonic supports -40°C to 85°C; (2) package diameter—SCHURTER is 14mm, Panasonic is 15.5mm; (3) capacitance at 1 kHz—SCHURTER is 8514 pF, Panasonic is 6500 pF; (4) product status—SCHURTER is obsolete, Panasonic is active.

Q: Is the capacitance difference significant for substitution?

A: The capacitance difference (8514 pF vs. 6500 pF) reflects normal manufacturing variation within the varistor category. Both values are within acceptable ranges for transient voltage suppression applications. Circuit-level impact depends on specific application requirements; verify against your circuit's frequency response and impedance specifications.

Q: Will the larger package diameter affect my PCB design?

A: The Panasonic part has a 15.5mm disc diameter compared to the SCHURTER 14mm diameter. Verify that your PCB layout accommodates the additional 1.5mm clearance. If space constraints exist, alternative suppliers or custom layouts may be required.

Q: What if my application requires operation above 85°C?

A: The Panasonic ERZ-V14D560 is rated to 85°C maximum. If your application requires sustained operation above this temperature, the narrower temperature range of the substitute part may not be acceptable. Consult with component suppliers for alternative 56 V varistor options with extended temperature ratings.
