Substitute Part Grouping Explanation

The T322D686K006AT qualifies as a direct substitute for the T322D686K006AS based on strict equivalence of the following critical parameters:

• Capacitance Value: Both parts are rated at 68 µF
• Voltage Rating: Both parts are rated for 6 V operation
• Tolerance: Both parts maintain ±10% tolerance
• ESR: Both parts specify 1.8 Ohm equivalent series resistance
• Operating Temperature Range: Both parts operate across -55°C to 125°C
• Molded Tantalum Type: Both parts are molded tantalum capacitors
• Axial Through-Hole Configuration: Both parts use identical axial lead geometry and through-hole mounting
• Physical Dimensions: Both parts share identical case dimensions of 0.180" Dia x 0.420" L (4.57mm x 10.67mm)
• Series Classification: Both parts belong to the T322 series

The primary distinction between these parts is regulatory compliance status. The T322D686K006AT achieves RoHS3 compliance, whereas the T322D686K006AS is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.
