Substitute Part Grouping Explanation

Substitution of the KXG400VB82RM18X25LL is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters:

  • Capacitance value: 82 µF
  • Voltage rating: 400 V
  • Tolerance: ±20%
  • Lifetime specification: 10,000 Hrs @ 105°C
  • Operating temperature range: -40°C ~ 105°C
  • Ripple current specifications: 610 mA @ 120 Hz and 1.525 A @ 100 kHz

Mechanical Parameters:

  • Package type: Radial, Can
  • Lead spacing: 0.295" (7.50 mm)
  • Physical dimensions: 0.709" Dia × 0.984" Height (Max)
  • Mounting type: Through Hole

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The EKXG401ELL820MM25S satisfies all specified parameters and is therefore a valid substitute for the obsolete KXG400VB82RM18X25LL.
