SCHURTER 0070.2011.A2 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0070.2011.A2 is a 33 V 250 A varistor in a through-hole disc 5mm package, designed for transient voltage suppression applications. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing procurement and system maintenance. The varistor provides single-circuit protection with a nominal voltage rating of 33 V and surge current capacity of 250 A, suitable for applications requiring reliable transient suppression in the specified voltage range.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 0070.2011.A2 is determined by the following critical parameters:

• Varistor voltage rating: 30 V minimum to 36 V maximum (33 V typical)
• Surge current capacity: 250 A
• Energy rating: 1.1 J
• Single circuit configuration
• Through-hole mounting type
• Operating temperature range compatibility
• RoHS3 compliance

The Panasonic ERZ-V05D330 meets all electrical substitution criteria. Physical package differences (5mm vs. 7mm disc diameter) must be evaluated for mechanical fit within the target application.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic ERZ-V05D330 is electrically equivalent to the SCHURTER 0070.2011.A2 across all critical transient suppression parameters. Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for equivalent component selection.

The primary consideration for substitution is the physical package dimension difference: the ERZ-V05D330 uses a 7mm disc package compared to the 5mm disc of the original part. This dimensional change requires verification of mechanical fit within the PCB layout and component mounting constraints of the target application.

The Panasonic part operates to a maximum temperature of 85°C, compared to 125°C for the SCHURTER part. Applications requiring operation above 85°C ambient temperature cannot use this substitute without thermal analysis.

The ERZ-V05D330 is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete SCHURTER part.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic ERZ-V05D330 directly replace the SCHURTER 0070.2011.A2 in all applications?

A: Electrical substitution is valid for applications operating within the Panasonic part's maximum temperature of 85°C. The 7mm disc package requires mechanical fit verification in the PCB layout. If the original design uses the 5mm package dimension as a critical constraint, physical redesign may be necessary.

Q: What are the key electrical parameters that must match for varistor substitution?

A: Varistor voltage rating (30-36 V range), surge current capacity (250 A), energy rating (1.1 J), and circuit count (1) must all match. These parameters determine transient suppression performance and circuit protection characteristics.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution from a regulatory standpoint.

Q: Why is the operating temperature range different?

A: The SCHURTER part is rated to 125°C while the Panasonic part is rated to 85°C. This reflects different design specifications and thermal characteristics. Applications with ambient temperatures above 85°C require the original SCHURTER part or alternative sources.

Q: What is the significance of the disc package size difference?

A: The 5mm and 7mm disc diameters affect PCB footprint and component spacing. The larger 7mm package may conflict with adjacent components or require PCB layout modification. Physical fit must be confirmed before implementation.
