Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0070.2011.B1 is determined by the following critical parameters:

• Varistor voltage rating: 33 V (minimum 30 V, maximum 36 V)
• Surge current capacity: 250 A
• Energy dissipation: 1.1 J
• Number of circuits: 1
• Mounting configuration: Through hole
• Maximum AC/DC voltage ratings: 20 V AC / 26 V DC
• RoHS3 compliance and REACH unaffected status

The Panasonic ERZ-V05D330 meets all electrical and functional requirements within these parameters. Physical package dimensions (disc 7mm versus disc 5mm) represent a mechanical variation that does not affect electrical performance or circuit functionality in standard through-hole mounting applications.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic ERZ-V05D330 is the direct electrical equivalent for the obsolete SCHURTER 0070.2011.B1. Both components satisfy identical electrical specifications across varistor voltage, surge current, energy dissipation, and voltage ratings. Both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The ERZ-V05D330 carries active product status, providing assured long-term availability and supply chain stability. 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 against specific circuit requirements.

The disc 7mm package of the ERZ-V05D330 versus the disc 5mm of the original represents a minor physical dimension increase. Standard through-hole PCB layouts accommodate this variation without design modification in most applications.

Frequently Asked Questions (FAQ)

Q: Are the electrical characteristics identical between the SCHURTER 0070.2011.B1 and Panasonic ERZ-V05D330?

A: Yes. Both components share identical varistor voltage ratings (30–36 V), surge current capacity (250 A), energy dissipation (1.1 J), and maximum AC/DC voltage specifications (20 V AC / 26 V DC).

Q: What is the significance of the package dimension difference (5mm vs. 7mm disc)?

A: The disc diameter increase from 5mm to 7mm is a mechanical variation that does not affect electrical performance. Through-hole mounting accommodates both sizes in standard PCB layouts without circuit modification.

Q: Does the narrower operating temperature range of the ERZ-V05D330 affect compatibility?

A: The Panasonic part operates from -40°C to 85°C, compared to the SCHURTER original's -40°C to 125°C. Applications requiring sustained operation above 85°C must evaluate thermal performance against specific circuit conditions.

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the SCHURTER 0070.2011.B1 and Panasonic ERZ-V05D330 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the availability status of the substitute part?

A: The Panasonic ERZ-V05D330 carries active product status, ensuring ongoing availability and supply chain continuity for new production and replacement applications.
