Substitute Part Grouping Explanation

Substitution of the T322D335K050AS is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part T322D335K050AT maintains identical specifications for capacitance (3.3 µF), voltage rating (50 V), tolerance (±10%), ESR (3 Ohm), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (axial), and physical dimensions (0.180" Dia x 0.420" L).

The primary distinction between these parts is regulatory compliance status. The T322D335K050AS is RoHS non-compliant, while the T322D335K050AT is RoHS3 compliant. Both parts are REACH Unaffected and classified under ECCN EAR99. This substitution relationship is valid only when all electrical and mechanical parameters remain constant across the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Selection between T322D335K050AS and T322D335K050AT is determined by regulatory and procurement requirements rather than electrical performance differences.

T322D335K050AS is appropriate for applications where RoHS compliance is not mandated and existing inventory or legacy system requirements necessitate the non-compliant variant. Both parts maintain Active product status and equivalent electrical performance.

T322D335K050AT is the required selection for applications subject to RoHS3 regulations, EU procurement directives, or organizational policies requiring RoHS compliance. This part provides identical electrical and mechanical performance while meeting current regulatory standards. Both parts are REACH Unaffected and carry EAR99 classification.

The choice between these parts does not affect circuit design, PCB layout, thermal management, or electrical performance characteristics. Substitution is electrically and mechanically transparent.

Frequently Asked Questions (FAQ)

Q: Can T322D335K050AT replace T322D335K050AS in existing designs?
