Frequently Asked Questions (FAQ)

Q: Can the KYOCERA AVX 04025G472ZAT2A be used as a direct replacement for the Panasonic ECJ-0EF1H472Z?

A: Yes. Both parts share identical capacitance (4700 pF), voltage rating (50V), temperature coefficient (Y5V), operating temperature range (-30°C to 85°C), and 0402 package dimensions. No circuit redesign is required.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both parts conform to the 0402 (1005 Metric) package standard with identical length (0.039"), width (0.020"), and maximum thickness (0.022").

Q: What is the significance of the Y5V temperature coefficient?

A: Y5V indicates a temperature coefficient range of -82% to +22% of nominal capacitance across the operating temperature range. This classification is suitable for general-purpose applications where moderate capacitance variation is acceptable.

Q: Does the tolerance specification affect substitution?

A: No. Both parts carry identical tolerance of -20%, +80%, ensuring equivalent capacitance accuracy in circuit operation.

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

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. Both parts can be stored and handled under standard conditions without special moisture control procedures.

Q: Is the KYOCERA AVX part available in the same packaging format?

A: The KYOCERA AVX part is supplied in Tape & Reel (TR) format, while the original Panasonic part packaging is not specified. Verify packaging requirements for your procurement and assembly process.
