Substitute Part Grouping Explanation

Substitution of the T322E686K010AS is based on strict electrical and mechanical compatibility within the KEMET T322 series. The identified substitute part maintains identical capacitance value (68 µF), tolerance (±10%), physical dimensions (0.280" Dia x 0.530" L), mounting type (through hole axial), and operating temperature range (-55°C ~ 125°C). The substitute differs in voltage rating and ESR characteristics. Substitution is valid when the circuit design permits operation at the higher voltage rating without adverse effects on component lifespan or circuit performance.

Key Parameters Determining Substitution:

• Capacitance: 68 µF (identical)
• Tolerance: ±10% (identical)
• Package / Case: Axial (identical)
• Mounting Type: Through Hole (identical)
• Physical Dimensions: 0.280" Dia x 0.530" L (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Voltage Rating: Higher voltage rating acceptable in applications with design margin

Parameter Comparison

Engineering Selection Recommendations

Both the T322E686K010AS and T322E686K020AS are active products manufactured by KEMET within the same T322 series. Selection between these parts is determined by circuit voltage requirements. The T322E686K010AS operates at 10 V rated voltage and is suitable for applications with voltage specifications at or below 10 V. The T322E686K020AS operates at 20 V rated voltage and provides additional voltage margin for circuits designed to operate below 20 V. The T322E686K020AS additionally features reduced ESR (900 mOhm versus 1.3 Ohm), which may provide improved performance in applications sensitive to impedance characteristics. Both parts share identical physical dimensions, capacitance, tolerance, and temperature operating range, ensuring mechanical and electrical compatibility in through-hole axial mounting applications. Neither part is RoHS compliant; both maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can T322E686K020AS replace T322E686K010AS in all applications?

A: The T322E686K020AS can replace T322E686K010AS when the circuit design permits operation at 20 V rated voltage. The substitute part maintains identical capacitance (68 µF), tolerance (±10%), physical dimensions, and mounting configuration. Verification that the circuit voltage does not exceed 20 V is required before substitution.

Q: What is the difference in ESR between these parts?

A: The T322E686K010AS has an ESR of 1.3 Ohm, while the T322E686K020AS has an ESR of 900 mOhm. The lower ESR of the substitute part may reduce heat generation and improve performance in high-frequency or high-current applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.280" diameter by 0.530" length (7.11mm x 13.46mm) and are packaged as axial through-hole components. They are mechanically interchangeable on printed circuit boards designed for the T322 series.

Q: What is the operating temperature range for both parts?

A: Both the T322E686K010AS and T322E686K020AS operate across -55°C to 125°C, providing identical thermal performance specifications.

Q: Are there RoHS or compliance considerations?

A: Both parts are RoHS non-compliant and REACH unaffected. Both carry EAR99 export classification. Compliance requirements for specific applications must be evaluated independently.
