Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T495B686M010ATE900 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 68 µF
• Voltage Rating: 10 V
• Operating Temperature Range: -55°C to 125°C
• Lifetime @ Temperature: 2000 Hrs @ 125°C

Mechanical Parameters (Must Match):

• Package / Case: 1411 (3528 Metric)
• Mounting Type: Surface Mount
• Type: Molded Tantalum

Allowable Variations:

• Tolerance: ±20% (main part) to ±10% (substitute parts) — tighter tolerance is acceptable
• ESR (Equivalent Series Resistance): 750 mOhm to 900 mOhm @ 100 kHz — variation within this range is acceptable

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Series: T495

The two substitute parts identified (T495B686K010ATE750 and T495B686K010ATE900) meet all mandatory electrical, mechanical, and compliance requirements while offering improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are Active product status components manufactured by KEMET and maintain full ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the main part.

T495B686K010ATE750: This substitute offers improved tolerance specification (±10% versus ±20%) and reduced ESR (750 mOhm versus 900 mOhm @ 100 kHz). Selection of this part is appropriate when lower equivalent series resistance is beneficial for circuit performance or when tighter capacitance tolerance is required.

T495B686K010ATE900: This substitute provides identical ESR characteristics (900 mOhm @ 100 kHz) to the main part while offering improved tolerance specification (±10% versus ±20%). This part is appropriate for direct substitution when tolerance improvement is desired without ESR modification.

All three parts share identical mechanical dimensions, package specifications, and thermal performance characteristics, ensuring direct PCB compatibility and thermal management equivalence.

Frequently Asked Questions (FAQ)

Q: Can T495B686K010ATE750 and T495B686K010ATE900 be used interchangeably with T495B686M010ATE900?

A: Both substitute parts meet the core electrical and mechanical requirements. The primary differences are tolerance specification (±10% versus ±20%) and ESR values. Selection depends on circuit requirements for capacitance accuracy and impedance characteristics.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: Tolerance defines the allowable deviation of actual capacitance from the nominal 68 µF value. The ±20% specification allows deviation from 54.4 µF to 81.6 µF, while ±10% allows deviation from 61.2 µF to 74.8 µF. Tighter tolerance (±10%) provides greater capacitance accuracy for applications requiring precise filtering or timing characteristics.

Q: What does ESR (Equivalent Series Resistance) represent?

A: ESR is the internal resistance of the capacitor measured at 100 kHz. Lower ESR (750 mOhm) indicates reduced impedance and improved high-frequency performance compared to higher ESR (900 mOhm). Selection depends on circuit frequency response requirements.

Q: Are all three parts physically identical?

A: Yes. All three parts share identical package dimensions (1411 / 3528 Metric), height (0.083" / 2.10mm maximum), and surface mount footprint. Direct PCB substitution is mechanically feasible without layout modification.

Q: Do all substitute parts maintain the same thermal and reliability characteristics?

A: Yes. All three parts operate across -55°C to 125°C and maintain 2000 hours lifetime at 125°C. Thermal performance and reliability ratings are equivalent.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical MSL (Moisture Sensitivity Level 1 / Unlimited) ratings. Regulatory and environmental compliance is equivalent.
