Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T495X227M010ATE080 are qualified based on the following criteria:

Core Electrical Parameters (Must Match):

• Capacitance: 220 µF
• Voltage Rating: 10 V
• Type: Molded Tantalum
• Operating Temperature Range: -55°C to 125°C
• Lifetime @ 125°C: 2000 Hrs

Mechanical Parameters (Must Match):

• Package / Case: 2917 (7343 Metric)
• Mounting Type: Surface Mount
• Physical Dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm)
• Height - Seated (Max): 0.169" (4.30mm)

Allowed Variation Parameters:

• Tolerance: ±10% or ±20% (both acceptable)
• ESR @ 100kHz: 80 mOhm to 500 mOhm (performance variation acceptable)
• Manufacturer: KEMET or Cal-Chip Electronics, Inc.
• Compliance: RoHS Compliant or RoHS3 Compliant

All four substitute parts meet these criteria and are direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are Active status components with full RoHS compliance. Selection between the main part and substitutes depends on ESR and tolerance requirements:

For ESR-Sensitive Applications (Lower ESR Preferred): Select TCKIA227ETLSR100 or TCMIA227ETLSR100 (100 mOhm ESR). These parts provide ESR performance closer to the original T495X227M010ATE080 (80 mOhm) and are suitable for applications requiring reduced ripple current effects.

For Standard ESR Applications: TCKIA227ET or TCMIA227ET (500 mOhm ESR) are suitable for general purpose applications where ESR is not a critical constraint.

For Tolerance Considerations: TCKIA227ET and TCKIA227ETLSR100 offer ±10% tolerance, providing tighter capacitance control. TCMIA227ET and TCMIA227ETLSR100 match the original ±20% tolerance specification.

All substitute parts maintain identical mechanical compatibility, thermal performance, and moisture sensitivity ratings. Inventory availability is significantly higher for Cal-Chip alternatives (20,815 to 21,117 units) compared to the original KEMET part (772 units).

Frequently Asked Questions (FAQ)

Q: Can TCKIA227ET replace T495X227M010ATE080 directly?

A: Yes. Both parts share identical capacitance (220 µF), voltage rating (10 V), package (2917), mounting type (surface mount), and operating temperature range (-55°C to 125°C). The TCKIA227ET has ±10% tolerance versus ±20% on the original, which is a tighter specification. ESR differs (500 mOhm vs. 80 mOhm), which may affect performance in ripple-current-sensitive circuits.

Q: What is the difference between TCKIA227ETLSR100 and TCKIA227ET?

A: Both are Cal-Chip 220 µF 10 V tantalum capacitors in 2917 package with ±10% tolerance. The primary difference is ESR: TCKIA227ETLSR100 has 100 mOhm ESR (lower), while TCKIA227ET has 500 mOhm ESR (higher). The "LSR100" designation indicates Low Series Resistance at 100 mOhm.

Q: Are Cal-Chip parts RoHS compliant?

A: Yes. All four Cal-Chip substitute parts (TCKIA227ET, TCKIA227ETLSR100, TCMIA227ET, TCMIA227ETLSR100) are RoHS Compliant. The original KEMET part is RoHS3 Compliant, which is a more recent standard. Both compliance levels are acceptable for equivalent substitution.

Q: Can I use TCMIA227ETLSR100 in place of T495X227M010ATE080?

A: Yes. TCMIA227ETLSR100 matches all core electrical and mechanical parameters: 220 µF capacitance, 10 V rating, 2917 package, surface mount, -55°C to 125°C operating range, and 2000 Hrs lifetime @ 125°C. It maintains ±20% tolerance matching the original and provides 100 mOhm ESR, which is closer to the original 80 mOhm specification than standard versions.

Q: Does package size differ between the main part and substitutes?

A: No. All parts use identical 2917 (7343 Metric) package with dimensions 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.169" (4.30mm). PCB layout and assembly compatibility are identical.

Q: Which substitute offers the best ESR performance?

A: TCKIA227ETLSR100 and TCMIA227ETLSR100 both provide 100 mOhm ESR, which is closest to the original T495X227M010ATE080 at 80 mOhm. These parts are designated with "LSR100" (Low Series Resistance) and are preferred for applications sensitive to ESR-related voltage ripple and thermal effects.

Q: Are all substitute parts in active production?

A: Yes. All four substitute parts maintain Active product status. The original KEMET T495X227M010ATE080 is also Active. All parts are available in Tape & Reel (TR) packaging for automated assembly.
