Frequently Asked Questions (FAQ)

Q: Can the CGA1A2X7R1E331M030BA replace the 0201B331M250CT in all applications?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The TDK part includes AEC-Q200 automotive qualification, making it suitable for both general-purpose and automotive applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are specified in the 0201 (0603 Metric) package with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). PCB footprints are interchangeable.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the significance of the X7R temperature coefficient?

A: X7R temperature coefficient specifies that capacitance variation remains within ±15% across the operating temperature range of -55°C to 125°C. Both parts maintain this specification identically.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8532.24.0020) codes. The TDK part adds AEC-Q200 automotive qualification without affecting general compliance status.

Q: Can tolerance specifications be mixed in a design?

A: Both parts are specified at ±20% tolerance. This tolerance applies to the capacitance value and must be considered in circuit design. Tighter tolerance parts are not available in this substitution group.

Q: What is the difference between general-purpose and automotive applications for these parts?

A: The TDK part carries AEC-Q200 automotive qualification, indicating it meets automotive industry reliability and testing standards. The Walsin part is specified for general-purpose applications. Both are electrically and mechanically compatible; the automotive rating extends the TDK part's qualified use cases.
