Key Parameters

Substitute Part Grouping Explanation

Substitution decisions for varistors are strictly based on matching the following parameters: varistor voltage ratings (minimum, typical, maximum), maximum AC and DC voltages, surge current capability, energy rating, capacitance at specified frequency, number of circuits, operating temperature, mounting type, package/case dimensions, and RoHS/REACH compliance. Only parts meeting all listed specifications can be considered direct substitutes for the designated part category.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0070.3081.T2 varistor is obsolete. The Panasonic ERZ-V20D470 is ROHS3 compliant and REACH unaffected, meeting current regulatory and environmental requirements. Both share identical compliance data and ECCN/HTSUS codes. The ERZ-V20D470 is classified as Active, ensuring supply continuity for new and ongoing designs that require substitution for the obsolete SCHURTER model.

Frequently Asked Questions (FAQ)

Q1: What are the critical criteria for substituting varistors in this category?
A1: Substitution is determined by matching varistor voltage ratings (minimum, typical, maximum), maximum AC/DC voltage, surge current capability, energy rating, capacitance at specified frequency, number of circuits, operating temperature range, mounting type, package/case dimensions, and regulatory compliance.

Q2: How does the package/case impact substitution for 0070.3081.T2?
A2: The main varistor uses a Disc 20mm package, while the substitute ERZ-V20D470 uses Disc 21.5mm. Engineering selection should confirm compatibility within mechanical constraints of the application.

Q3: Are there differences in operating temperature specifications?
A3: The SCHURTER 0070.3081.T2 supports -40°C to 125°C, while the ERZ-V20D470 supports -40°C to 85°C. Confirm that the substitute meets the specific operating temperature requirements for the intended environment.

Q4: How do regulatory compliance and certification affect substitution?
A4: Both the SCHURTER 0070.3081.T2 and Panasonic ERZ-V20D470 are ROHS3 compliant and REACH unaffected, supporting direct substitution in regulated environments.

Q5: Can the ERZ-V20D470 directly replace SCHURTER 0070.3081.T2 in all electrical designs?
A5: Based strictly on provided electrical and mechanical parameters, the ERZ-V20D470 matches key specifications required for substitution in this varistor category. Check mechanical fit and operating temperature in the application.
