Substitute Part Grouping Explanation

Substitution eligibility for the T520B686M006ATE0707622 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 68 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• ESR specification: 70 mOhm @ 100kHz (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Lifetime specification: 2000 Hours @ 105°C (exact match required)

The identified substitute part T520B686M006ATE070 meets all these criteria and is therefore electrically and mechanically interchangeable for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Both the main part T520B686M006ATE0707622 and the substitute T520B686M006ATE070 are active products from KEMET's KO-CAP® T520 series with identical electrical and mechanical specifications. Both parts maintain RoHS3 compliance and are suitable for direct substitution in applications requiring 68 µF capacitance at 6.3 V with 70 mOhm ESR characteristics. Selection between these parts may be based on inventory availability, lead time, or procurement source, as no technical differentiation exists between them.
