Substitute Part Grouping Explanation

Substitute parts for the T495X227K010ATE080 are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Capacitance: 220 µF
• Tolerance: ±10%
• Voltage Rating: 10 V
• Type: Molded Tantalum
• Package / Case: 2917 (7343 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 125°C
• Lifetime @ 125°C: 2000 Hrs

Variable Parameters (Allowed Substitution Criteria):

• ESR (Equivalent Series Resistance): Substitute parts may have different ESR values. Lower ESR values provide improved performance characteristics and are acceptable alternatives.
• Manufacturer: Different manufacturers producing equivalent specifications
• RoHS Status: Both RoHS3 and RoHS compliant parts are acceptable

The identified substitute parts TCKIA227ET and TCKIA227ETLSR100 from Cal-Chip Electronics, Inc. meet all mandatory matching parameters and are therefore qualified as electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

T495X227K010ATE080 (KEMET - Primary Part)

Selection criteria: Use when lowest ESR performance is required. The 80 mOhm ESR specification provides optimal performance for applications sensitive to impedance characteristics. RoHS3 compliance status aligns with the most current regulatory requirements.

TCKIA227ETLSR100 (Cal-Chip Electronics - Preferred Substitute)

Selection criteria: Use as primary substitute when supply constraints affect KEMET availability. The 100 mOhm ESR is marginally higher than the main part but remains within acceptable performance parameters for general purpose applications. RoHS compliant status meets regulatory requirements. Active product status ensures continued availability.

TCKIA227ET (Cal-Chip Electronics - Secondary Substitute)

Selection criteria: Use when cost optimization is prioritized and application circuit design accommodates higher ESR values. The 500 mOhm ESR represents a significant increase from the main part specification and should be evaluated for circuit performance impact. RoHS compliant status and Active product status confirm regulatory compliance and supply continuity.

All substitute parts maintain identical electrical ratings (220 µF, 10 V, ±10%), mechanical dimensions (2917 package), and thermal specifications (-55°C to 125°C operating range, 2000 Hrs @ 125°C lifetime). Substitution is mechanically and electrically valid based on provided specifications.

Frequently Asked Questions (FAQ)

Q: Can TCKIA227ET and TCKIA227ETLSR100 be used interchangeably with T495X227K010ATE080?

A: Both Cal-Chip parts are electrical and mechanical equivalents based on matching capacitance (220 µF), voltage rating (10 V), tolerance (±10%), package (2917), and operating temperature range (-55°C to 125°C). The primary difference is ESR specification. TCKIA227ETLSR100 with 100 mOhm ESR is closer to the original 80 mOhm specification. TCKIA227ET with 500 mOhm ESR requires circuit-level evaluation for compatibility.

Q: What is the significance of ESR differences between these parts?

A: ESR (Equivalent Series Resistance) affects impedance characteristics and ripple current handling. The T495X227K010ATE080 specifies 80 mOhm, TCKIA227ETLSR100 specifies 100 mOhm, and TCKIA227ET specifies 500 mOhm. Lower ESR values provide better high-frequency performance. Applications with strict impedance requirements should prioritize parts with lower ESR values.

Q: Are all three parts RoHS compliant?

A: Yes. T495X227K010ATE080 is RoHS3 compliant. TCKIA227ET and TCKIA227ETLSR100 are RoHS compliant. Both compliance levels meet current regulatory requirements. All parts are REACH Unaffected.

Q: Do these parts have identical physical dimensions?

A: Yes. All three parts use the 2917 (7343 Metric) package with dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.169" (4.30mm). They are mechanically interchangeable in PCB layouts.

Q: What is the Moisture Sensitivity Level for these parts?

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts suitable for -55°C to 125°C operating environments?

A: Yes. All three parts are rated for -55°C to 125°C operating temperature range with 2000 Hrs lifetime specification at 125°C, confirming suitability for extended temperature applications.

Q: What is the difference between RoHS3 and RoHS compliance?

A: RoHS3 represents the most current regulatory standard. RoHS represents earlier compliance versions. Both are acceptable for regulatory purposes. T495X227K010ATE080 meets the newer RoHS3 standard, while Cal-Chip parts meet RoHS standard.
