Key Parameters

Substitute Part Grouping Explanation

Substitution of the CWR29FC156KCDB with equivalent parts is based on compatibility across the following key parameters:

• Capacitance Value: 15 µF
• Voltage Rating: 25 V
• Package Type: 2917 (7343 Metric)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8532.21.0050

Substitute parts must maintain identical or compatible electrical characteristics and physical dimensions to ensure functional equivalence in the application.

Parameter Comparison

Engineering Selection Recommendations

CWR29FC156KCDB (KYOCERA AVX): Active product status with unlimited moisture sensitivity rating. Non-RoHS compliant. Suitable for applications without RoHS requirements.

T491D156K025AT (KEMET): Active product status with unlimited moisture sensitivity rating. ROHS3 compliant. Recommended for applications requiring RoHS compliance. Both parts share identical electrical ratings (15 µF at 25 V) and package dimensions (2917 metric), enabling direct substitution. The KEMET part offers enhanced compliance posture while maintaining functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can T491D156K025AT replace CWR29FC156KCDB in all applications? A: Both parts share identical capacitance (15 µF), voltage rating (25 V), and package dimensions (2917 metric). The primary difference is RoHS compliance status. Substitution is suitable when RoHS compliance is required or when inventory of the original part is unavailable.

Q: What are the critical parameters for tantalum capacitor substitution? A: Critical parameters include capacitance value, voltage rating, package type, and moisture sensitivity level. Both the CWR29FC156KCDB and T491D156K025AT match across all these parameters.

Q: What is the package type for these components? A: Both components use the 2917 package type (7343 metric), with dimensions of 0.287" L x 0.169" W and maximum seated height of 0.122".

Q: Are there differences in temperature performance? A: The T491D156K025AT specifies operating temperature range of -55°C ~ 125°C and lifetime rating of 2000 hours at 125°C. The original part specifications do not include these details in the provided data.

Q: What is the packaging difference between these parts? A: The CWR29FC156KCDB is supplied in bulk packaging, while the T491D156K025AT is supplied in Tape & Reel (TR) format. Both formats contain the same component; packaging selection depends on assembly process requirements.
