Key Parameters

Substitute Part Grouping Explanation

Substitution of the V275LC10 is determined by strict equivalence across the following electrical and mechanical parameters:

• Varistor voltage range (387 V minimum to 473 V maximum)
• Surge current rating (2.5 kA)
• Energy absorption capacity (45 J)
• Maximum AC and DC voltage ratings (275 V AC, 369 V DC)
• Operating temperature range (-55°C to 85°C)
• Through-hole mounting configuration
• Disc 10mm package geometry
• Single-circuit configuration
• Capacitance specification (200 pF @ 1 MHz)

The V275LC10P meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is packaging format and product status.
