Substitute Part Grouping Explanation

Substitute varistor models must match all critical parameters, including Maximum AC Voltage, Maximum DC Voltage, Varistor Voltage ratings (minimum, typical, maximum), surge current capacity, energy rating, number of circuits, capacitance at specified frequency, operating temperature, mounting type, and package size. Regulatory status (RoHS, REACH), part series, and product compliance identifiers are also required criteria for substitution.

Key parameters considered for grouping:

• Maximum AC Volts
• Maximum DC Volts
• Varistor Voltage (Min, Typ, Max)
• Current - Surge
• Energy
• Number of Circuits
• Capacitance @ Frequency
• Operating Temperature
• Mounting Type
• Package / Case
• Series
• RoHS/REACH Status
• MSL
• ECCN
• HTSUS

Parameter Comparison

Engineering Selection Recommendations

ERZ-E10A331CS and ERZ-E10A331 are both active with identical compliance designations, including RoHS3 Compliant and REACH Unaffected status. Both have the same ECCN and HTSUS classification, enabling direct substitution in applications where regulatory alignment is required. Both parts are available in stock.
