Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T520C227M2R5ATE045 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters (Must Match Exactly):

• Capacitance: 220 µF
• Voltage - Rated: 2.5 V
• Tolerance: ±20%
• Package / Case: 2312 (6032 Metric)
• Mounting Type: Surface Mount
• Type: Molded Tantalum Polymer
• Operating Temperature Range: -55°C ~ 105°C
• Lifetime @ Temp.: 2000 Hrs @ 105°C

Allowed Variation Parameter:

• ESR (Equivalent Series Resistance) @ 100kHz: Lower values are acceptable as they represent improved performance characteristics while maintaining functional compatibility.

The T520C227M2R5ATE025 qualifies as a substitute because it maintains all critical parameters while offering reduced ESR (25 mOhm @ 100kHz versus 45 mOhm @ 100kHz), representing an equivalent or superior alternative for the same application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the T520C227M2R5ATE045 and T520C227M2R5ATE025 are active products from KEMET's KO-CAP® T520 series with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically interchangeable for applications requiring 220 µF at 2.5 V in a 2312 surface mount package.

The T520C227M2R5ATE025 offers lower ESR (25 mOhm @ 100kHz) compared to the main part (45 mOhm @ 100kHz), which reduces impedance and improves transient response characteristics. This makes the substitute part suitable for applications where lower ESR is beneficial or required. Both parts maintain identical thermal performance, moisture sensitivity ratings, and mechanical dimensions, ensuring direct PCB compatibility without layout modifications.

Selection between these parts depends on circuit requirements for ESR performance. The substitute part represents an equivalent or enhanced alternative when lower series resistance is acceptable or preferred.
