Substitute Part Grouping Explanation

Substitution of the T322B334K050AS is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-negotiable):

  • Capacitance: 0.33 µF
  • Voltage Rating: 50 V
  • Tolerance: ±10%
  • ESR: 15 Ohm
  • Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Non-negotiable):

  • Mounting Type: Through Hole
  • Package / Case: Axial
  • Size / Dimension: 0.110" Dia x 0.290" L (2.79mm x 7.37mm)

Technology:

  • Type: Molded Tantalum

The T322B334K050AT qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is regulatory compliance status: T322B334K050AT is ROHS3 Compliant, whereas T322B334K050AS is RoHS non-compliant. Both parts share the same base product number (T322B) and series designation.
