Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T495X476M025ATE080 is determined by the following core parameters:

Primary Matching Criteria (Non-Negotiable):

• Capacitance: 47 µF
• Voltage Rating: 25 V
• Package / Case: 2917 (7343 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 125°C

Secondary Allowable Variations:

• Tolerance: ±10% or ±20% acceptable
• ESR @ 100 kHz: Range from 80 mOhm to 900 mOhm
• Manufacturer: KEMET or Cal-Chip Electronics, Inc.
• RoHS Status: ROHS3 Compliant or RoHS Compliant

All identified substitute parts meet the primary matching criteria. Variations in tolerance and ESR are within acceptable engineering parameters for general-purpose tantalum capacitor applications. Compliance certifications (RoHS, REACH, ECCN) are maintained across all substitutes.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and comply with RoHS and REACH regulations. Selection between the main part and substitutes is based on the following considerations:

T495X476M025ATE080 (Main Part): Lowest ESR at 80 mOhm @ 100 kHz. Optimal for applications requiring minimal impedance. ROHS3 Compliant.

T495X476M025ATE100: Same series and tolerance as main part. ESR of 100 mOhm @ 100 kHz represents minimal increase from main part specification. ROHS3 Compliant. Direct series equivalent with slightly higher ESR.

T494X476K025AT: KEMET T494 series with tighter ±10% tolerance. ESR of 300 mOhm @ 100 kHz. ROHS3 Compliant. Suitable where tolerance precision is required and higher ESR is acceptable.

TCKIE476ET and TCMIE476ET: Cal-Chip Electronics alternatives with ±10% and ±20% tolerance respectively. ESR of 900 mOhm @ 100 kHz. RoHS Compliant (non-ROHS3). Suitable for general-purpose applications where ESR tolerance is not critical.

All parts share identical package dimensions, operating temperature range, and lifetime specifications. Component selection should be based on ESR requirements, tolerance specifications, and compliance certifications applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can T495X476M025ATE100 be used as a direct replacement for T495X476M025ATE080?

A: Yes. Both parts are from the same KEMET T495 series with identical capacitance (47 µF), voltage rating (25 V), tolerance (±20%), package (2917), and operating temperature range (-55°C ~ 125°C). The ESR difference of 20 mOhm (80 mOhm vs. 100 mOhm @ 100 kHz) is within acceptable variation for general-purpose applications.

Q: What is the difference between KEMET T495 and T494 series?

A: The primary difference is tolerance specification. T495 series offers ±20% tolerance, while T494 series offers ±10% tolerance. Both series share identical capacitance, voltage rating, package dimensions, and operating temperature range. ESR values differ between series.

Q: Are Cal-Chip Electronics TCKIE476ET and TCMIE476ET compatible with KEMET parts?

A: Yes, for package and dimensional compatibility. Both Cal-Chip parts match the 2917 (7343 Metric) package, capacitance (47 µF), voltage rating (25 V), and operating temperature range. The primary difference is ESR at 900 mOhm @ 100 kHz, which is higher than KEMET equivalents. Compliance status differs: Cal-Chip parts are RoHS Compliant (not ROHS3).

Q: What does ESR variation mean for circuit performance?

A: ESR (Equivalent Series Resistance) affects impedance characteristics. Lower ESR values (80-100 mOhm) provide lower impedance. Higher ESR values (300-900 mOhm) increase impedance. Selection depends on circuit requirements for ripple current handling and frequency response.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All parts listed are supplied in Tape & Reel (TR) packaging for automated surface mount assembly. Physical dimensions are identical: 0.287" L x 0.169" W (7.30mm x 4.30mm) with maximum seated height of 0.169" (4.30mm).

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture exposure controls. All parts listed have MSL 1 rating, requiring no special moisture protection during storage or handling.

Q: Do all parts meet RoHS compliance requirements?

A: KEMET parts (T495X476M025ATE080, T494X476K025AT, T495X476M025ATE100) are ROHS3 Compliant. Cal-Chip parts (TCKIE476ET, TCMIE476ET) are RoHS Compliant. Both compliance levels are acceptable; ROHS3 represents the most current standard.
