Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0070.1711.T2 is determined by the following critical parameters:

• Varistor Voltage (Typ): 27 V
• Current - Surge: 250 A
• Energy: 0.9 J
• Number of Circuits: 1
• Mounting Type: Through Hole
• Maximum AC Volts: 17 V
• Maximum DC Volts: 22 V
• Varistor Voltage Range: 24 V (Min) to 30 V (Max)

The Panasonic ERZ-V05D270 meets all critical electrical parameters and operates within the same voltage and current specifications. Both components share identical surge current ratings, energy dissipation capacity, and voltage classification boundaries. The primary physical difference is the package diameter (5mm vs. 7mm), which may require PCB layout verification for mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic ERZ-V05D270 is an active product with full ROHS3 and REACH compliance, providing supply continuity for the obsolete SCHURTER 0070.1711.T2. Electrical performance is equivalent across all critical transient suppression parameters: voltage classification, surge current capacity, and energy dissipation.

The operating temperature range of the Panasonic substitute extends to 85°C maximum, compared to 125°C for the original part. Applications requiring operation above 85°C ambient temperature require thermal analysis to confirm the substitute remains within safe operating limits.

The package diameter difference (7mm vs. 5mm) necessitates PCB layout verification. Existing through-hole footprints designed for 5mm disc packages may require modification to accommodate the 7mm diameter of the substitute component.

Frequently Asked Questions (FAQ)

Q: Are the electrical characteristics of the Panasonic ERZ-V05D270 identical to the SCHURTER 0070.1711.T2?

A: Yes. Both components share identical varistor voltage specifications (24V–30V range, 27V typical), surge current rating (250A), and energy dissipation (0.9J). Capacitance differs slightly (1600 pF vs. 1450 pF @ 1 kHz), which is within normal manufacturing tolerance for varistor components.

Q: What is the impact of the package size difference?

A: The substitute uses a 7mm disc package versus the original 5mm disc. This affects PCB footprint dimensions and mounting hole spacing. Physical verification of the PCB layout is required before component substitution.

Q: Can the Panasonic part be used in applications operating above 85°C?

A: The Panasonic ERZ-V05D270 is rated to 85°C maximum ambient temperature, while the original SCHURTER part operates to 125°C. Applications requiring sustained operation above 85°C require thermal modeling to confirm the substitute component remains within safe operating limits under worst-case conditions.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the SCHURTER 0070.1711.T2 and Panasonic ERZ-V05D270 are ROHS3 compliant and REACH unaffected.

Q: What is the availability status of each component?

A: The SCHURTER 0070.1711.T2 is obsolete. The Panasonic ERZ-V05D270 is an active product with current inventory availability.
