Engineering Selection Recommendations

All three substitute parts—04023G223ZAT2A (KYOCERA AVX), CC0402ZRY5V8BB223 (YAGEO), and CL05F223ZA5NNNC (Samsung Electro-Mechanics)—are active production components with full parametric equivalence to the obsolete ECJ-0EF1E223Z.

KYOCERA AVX 04023G223ZAT2A and Samsung Electro-Mechanics CL05F223ZA5NNNC both carry ROHS3 compliance and REACH unaffected status. YAGEO CC0402ZRY5V8BB223 also maintains ROHS3 compliance and REACH unaffected status. All three substitutes are classified as MSL 1 (Unlimited moisture sensitivity level), matching the original component's environmental rating.

Component selection should prioritize availability and supply chain continuity. YAGEO CC0402ZRY5V8BB223 offers the highest inventory level at 31,427 pieces, providing superior supply assurance for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the ECJ-0EF1E223Z?

A: Yes. All listed substitute parts meet identical electrical specifications (0.022 µF, 25V, Y5V temperature coefficient, -30°C to 85°C operating range) and mechanical requirements (0402 package, surface mount MLCC). Direct substitution is supported without circuit redesign.

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

A: Y5V indicates the capacitance change limits across the operating temperature range. The Y5V classification specifies -30°C to 85°C operating range with defined capacitance stability. All substitute parts maintain this same temperature coefficient specification.

Q: Are there packaging differences between these parts?

A: All parts use 0402 (1005 Metric) surface mount packages with identical physical dimensions (0.039" L x 0.020" W, 0.022" maximum thickness). KYOCERA AVX 04023G223ZAT2A and YAGEO CC0402ZRY5V8BB223 are supplied in Tape & Reel packaging. Samsung Electro-Mechanics CL05F223ZA5NNNC packaging specification is not detailed but maintains the same 0402 form factor.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All parts in this comparison carry MSL 1 rating.

Q: Which substitute offers the best supply availability?

A: YAGEO CC0402ZRY5V8BB223 maintains the highest inventory at 31,427 pieces, providing optimal supply continuity for production applications.
