Parameter Comparison

Engineering Selection Recommendations

The T491C226K016AT (KEMET) is a direct substitute for the T491C226K016AS-F (CDE). Both components share identical electrical specifications, physical dimensions, and package configurations. The KEMET part carries Active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete CDE original.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, supporting equivalent environmental and regulatory requirements. The KEMET substitute provides specified ESR and lifetime characteristics at rated temperature, offering additional performance documentation for applications requiring detailed component specifications.

Frequently Asked Questions (FAQ)

Q: Can the T491C226K016AT replace the T491C226K016AS-F in existing designs?

A: Yes. Both components share identical capacitance (22 µF), tolerance (±10%), voltage rating (16 V), package type (2312/6032 Metric), and physical dimensions. Direct substitution is supported without circuit modification.

Q: Are there physical compatibility concerns when substituting these parts?

A: No. Both components have identical mounting type (surface mount), footprint dimensions (0.236" L x 0.126" W), and maximum seated height (0.110"). PCB layouts and assembly processes require no adjustment.

Q: What is the primary advantage of using the KEMET substitute?

A: The T491C226K016AT maintains Active product status, ensuring reliable long-term availability. The original CDE part is obsolete, creating supply constraints. Both parts meet identical electrical and compliance requirements.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both the T491C226K016AS-F and T491C226K016AT are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity ratings, and share identical ECCN (EAR99) and HTSUS classifications.

Q: Is the ESR specification critical for substitution decisions?

A: The KEMET substitute specifies 1.6 Ohm ESR with 2000 Hrs lifetime at 125°C. The original part does not provide these specifications. For applications where ESR performance is critical, the KEMET part's documented characteristics provide additional design assurance.

Q: What is the operating temperature range for both parts?

A: Both components operate across -55°C to 125°C, supporting identical thermal performance requirements in industrial and commercial applications.
