Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 101KD10 are identified through parametric equivalence. The substitution logic is based on the following critical parameters that must match or remain within specification:

• Varistor Voltage (Typical): 100 V nominal with tolerance range 90–110 V
• Surge Current Rating: 2.5 kA minimum
• Energy Absorption: 15 J minimum
• Package Form Factor: Disc 10mm through-hole configuration
• Operating Temperature Range: −40°C to +105°C
• Number of Circuits: Single circuit (1)
• Capacitance: 1000 pF @ 1 kHz
• AC/DC Voltage Limits: 60 V AC maximum, 85 V DC maximum

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign.
