Substitute Part Grouping Explanation

Substitution eligibility for the ERZ-E14A681SC is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (612 - 748 V range)
• Surge current capacity (7.5 kA minimum)
• Energy absorption (382 J)
• Capacitance specification (600 pF @ 1 kHz)
• Operating temperature range (-40°C to 125°C)
• Package form factor (Disc 14mm)
• Mounting configuration (Through Hole)
• Number of circuits (1)

The substitute part ERZ-E14A681S1 meets all these criteria and is therefore classified as a parametric equivalent. Both parts share identical electrical performance characteristics and mechanical compatibility, enabling direct substitution in circuit applications.
