Substitute Part Grouping Explanation

Substitution of the T496D226M020AS is determined by strict equivalence in the following parameters:

  • Capacitance Value: 22 µF (exact match required)
  • Voltage Rating: 20 V (exact match required)
  • Package / Case: 2917 (7343 Metric) (exact match required)
  • Mounting Type: Surface Mount (exact match required)
  • Physical Dimensions: 0.287" L x 0.169" W x 0.122" H maximum seated height (exact match required)
  • Type: Molded Tantalum (exact match required)
  • Features: Fail Safe with Built-in Fuse (exact match required)

Substitute parts may vary in tolerance specification (±20% or ±10%) and ESR (Equivalent Series Resistance) characteristics, provided all primary electrical and mechanical parameters remain identical. Parts listed as active with current product status are preferred for new applications.
