Substitute Part Grouping Explanation

Substitute parts for the T322C106K015AS are classified into two categories based on allowed electrical and mechanical parameters:

Direct Equivalent (Same Electrical Specifications): The T322C106K015AT maintains identical electrical characteristics: 10 µF capacitance, ±10% tolerance, 15 V rated voltage, 3.2 Ohm ESR, and -55°C to 125°C operating temperature range. This part differs only in packaging designation (T suffix versus S suffix) and compliance status. Both parts share the same physical dimensions, mounting type, and series classification.

Voltage-Upgraded Substitute (Higher Voltage Rating): The T322C106K020AS provides the same 10 µF capacitance and ±10% tolerance but with a 20 V rated voltage instead of 15 V. This higher voltage rating results in a lower ESR of 2.9 Ohm compared to 3.2 Ohm. Physical dimensions, mounting type, and operating temperature range remain identical. This part functions as an upgrade option for applications requiring additional voltage margin.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): The T322C106K015AT serves as a direct equivalent to the T322C106K015AS. Selection between these two parts should be based on compliance requirements. The T322C106K015AT achieves ROHS3 compliance, whereas the T322C106K015AS is RoHS non-compliant. Both parts maintain identical electrical performance, physical dimensions, and thermal operating range. Inventory availability also differs: T322C106K015AT has 1123 units in stock compared to 791 units for the main part.

For Voltage-Margin Applications: The T322C106K020AS provides a higher 20 V rated voltage while maintaining the same 10 µF capacitance and ±10% tolerance. This part introduces a lower ESR of 2.9 Ohm, compared to 3.2 Ohm in the 15 V variants. Selection of this upgrade is appropriate for circuits requiring additional voltage safety margin or where the lower ESR characteristic provides performance benefits. Physical compatibility remains unchanged. This part is RoHS non-compliant, matching the compliance status of the main part.

Frequently Asked Questions (FAQ)

Q: Can T322C106K015AT be used as a direct replacement for T322C106K015AS?

A: Yes. Both parts are identical in electrical specifications (10 µF, ±10%, 15 V, 3.2 Ohm ESR), operating temperature range (-55°C to 125°C), physical dimensions (0.180" Dia x 0.345" L), and mounting configuration (axial through-hole). The primary difference is RoHS compliance status: T322C106K015AT is ROHS3 compliant while T322C106K015AS is not.

Q: What is the difference between T322C106K015AS and T322C106K020AS?

A: Both parts share identical capacitance (10 µF), tolerance (±10%), physical dimensions, and operating temperature range. The T322C106K020AS has a higher rated voltage of 20 V compared to 15 V, and a lower ESR of 2.9 Ohm versus 3.2 Ohm. The 20 V part is suitable for applications requiring additional voltage headroom.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts (T322C106K015AS, T322C106K015AT, and T322C106K020AS) share identical physical dimensions of 0.180" Dia x 0.345" L (4.57mm x 8.76mm), axial package configuration, and through-hole mounting type. They are mechanically interchangeable on PCBs designed for the T322 series size code C.

Q: Which part should be selected for new designs?

A: Selection depends on compliance and performance requirements. For RoHS3-compliant designs, use T322C106K015AT. For applications requiring voltage margin or lower ESR characteristics, use T322C106K020AS. All three parts are active products with current manufacturing status.

Q: Does the lower ESR of T322C106K020AS affect circuit performance?

A: The T322C106K020AS has an ESR of 2.9 Ohm compared to 3.2 Ohm in the 15 V variants. Lower ESR reduces impedance at high frequencies and heat dissipation. This characteristic may be beneficial in high-frequency filtering or low-impedance applications, but compatibility depends on circuit design specifications.
