Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied in order of priority:

Capacitance Value: Must be 220 µF (±20% tolerance)
Voltage Rating: Must be equal to or greater than 2.5 V
Package / Case: Must be 1411 (3528 Metric) for direct mechanical compatibility
Type: Must be molded tantalum polymer capacitor
Operating Temperature: Must support -55°C to 105°C range
ESR Characteristics: Lower ESR values are acceptable; higher values require application verification

Parts are categorized as follows:

Direct Equivalent: Identical voltage rating (2.5 V), same package, matching ESR specification
Upgrade: Higher voltage rating (4 V or 6.3 V), same package, same ESR, suitable for applications with voltage margin requirements
Similar: Different package variant (1210 vs 1411), higher ESR, same voltage and capacitance
Parametric Equivalent: Identical electrical specifications, alternative manufacturer

Engineering Selection Recommendations

T520B227M2R5ATE015 (KEMET) is the primary direct equivalent. It maintains 2.5 V rating and 1411 package compatibility with improved ESR performance (15 mOhm vs 45 mOhm). ROHS3 compliance and active product status support long-term availability. Moisture sensitivity level 3 (168 hours) requires standard handling procedures.

T520B227M004ATE045 and T520B227M006ATE045 (KEMET) are upgrade options providing higher voltage ratings (4 V and 6.3 V respectively) while maintaining identical ESR and package specifications. These are suitable for applications requiring voltage margin above the 2.5 V minimum.

T55B227M2R5C0045 (Vishay Polytech) provides parametric equivalence with identical electrical specifications and 2.5 V rating. Active product status and ROHS3 compliance ensure availability. Height dimension matches the original part (0.083").

TCJB227M006R0200 (KYOCERA AVX) differs in package (1210 vs 1411) and exhibits significantly higher ESR (200 mOhm). This part is suitable only when PCB layout accommodates the 1210 package and circuit design tolerates elevated ESR.

Frequently Asked Questions (FAQ)

Q: Can T520B227M004ATE045 (4 V rating) be used in place of F320E227MBA (2.5 V rating)?

A: Yes. Higher voltage-rated capacitors are electrically compatible in circuits designed for lower voltages. The 4 V rating provides additional voltage margin without affecting capacitance or ESR performance.

Q: What is the significance of the ESR difference between F320E227MBA (45 mOhm) and T520B227M2R5ATE015 (15 mOhm)?

A: Lower ESR reduces heat dissipation and improves high-frequency performance. T520B227M2R5ATE015 is a direct improvement. Applications sensitive to ESR specifications should verify circuit performance requirements before substitution.

Q: Why is TCJB227M006R0200 listed as a similar part rather than a direct substitute?

A: TCJB227M006R0200 uses 1210 package instead of 1411, requiring PCB layout modification. ESR is significantly higher (200 mOhm vs 45 mOhm), affecting circuit performance. Use only when package change is feasible and ESR tolerance is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: T520B227M2R5ATE015, T520B227M004ATE045, T520B227M006ATE045, TCJB227M006R0200, and T55B227M2R5C0045 are all ROHS3 compliant. The original F320E227MBA (obsolete) has no stated RoHS status.

Q: What is the moisture sensitivity level (MSL) requirement for substitute parts?

A: KEMET and KYOCERA AVX substitutes specify MSL 3 (168 hours), requiring storage in controlled humidity and baking before reflow soldering. Vishay Polytech T55B227M2R5C0045 also specifies MSL 3. Standard ESD and moisture handling procedures apply.

Q: Can substitute parts be mixed in the same production batch?

A: Yes, provided all parts meet the circuit's electrical requirements (capacitance, voltage, ESR). Verify thermal and mechanical compatibility with PCB layout and assembly processes.
