Frequently Asked Questions (FAQ)

Q1: What are the main criteria for selecting a substitute for 0070.1741.A2?
A1: Selection is based strictly on matching electrical parameters (maximum AC/DC voltage, varistor voltage, current surge, energy, and capacitance), mechanical format (mounting type, package size), operating temperature, number of circuits, and compliance with RoHS and REACH.

Q2: Is the substitute ERZ-V10D270 compatible in terms of voltage and current ratings?
A2: Yes, all maximum AC volts, maximum DC volts, varistor voltage (min/typ/max), and current-surge ratings are identical.

Q3: Are there differences in packaging or size between the main and substitute parts?
A3: The main part uses a 10 mm disc, while the substitute part uses an 11.5 mm disc. Both are through-hole mechanical mounting types.

Q4: Does the substitute part have the same compliance and regulatory status?
A4: Both parts are ROHS3 compliant and REACH unaffected.

Q5: How does the operating temperature range affect substitution?
A5: The main part has an operating temperature of -40°C to 125°C. The substitute part operates from -40°C to 85°C. This difference should be evaluated against the required application range.

Q6: Is there a difference in capacitance between the parts?
A6: The main part's capacitance at 1 kHz is 4000 pF, while the substitute's is 8000 pF at 1 kHz. Both values are provided for comparison and should be reviewed for any circuit sensitivity.
