ERZ-E11A331CS Equivalent & Substitute Parts

Part Overview

The ERZ-E11A331CS is a 330V, 6kA Transient Voltage Suppressor (TVS) varistor manufactured by Panasonic Electronic Components. This through-hole disc varistor (13mm) is designed for transient overvoltage protection in electronic circuits. The part is currently Active in product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain disruptions necessitate alternative sourcing while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERZ-E11A331CS is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (297V minimum to 363V maximum range)
• Surge current capacity (6 kA)
• Energy absorption (115 J)
• Mounting configuration (Through Hole)
• Physical package (Disc 13mm)
• Operating temperature range (-40°C to 85°C)
• Regulatory compliance (RoHS3, REACH unaffected)

Only parts meeting all these criteria are classified as parametric equivalents. The ERZ-E11A331 qualifies as a direct substitute based on identical electrical specifications and mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the ERZ-E11A331CS and ERZ-E11A331 are Active products from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and lead time requirements. Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in all applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part. Component selection can proceed with either part number without modification to circuit design or PCB layout.

Frequently Asked Questions (FAQ)

Q: Can ERZ-E11A331 be used as a direct replacement for ERZ-E11A331CS?
