ECJ-2YF1C225Z Equivalent & Substitute Parts

Part Overview

The Panasonic ECJ-2YF1C225Z is a 2.2 µF ceramic capacitor rated at 16V with Y5V temperature coefficient in 0805 (2012 Metric) surface mount package. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part is suitable for general-purpose applications requiring stable capacitance across the -30°C to 85°C operating temperature range with -20%, +80% tolerance specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance value (2.2 µF), voltage rating (16V minimum), temperature coefficient (Y5V), tolerance (-20%, +80%), package type (0805 / 2012 Metric), and mounting configuration (Surface Mount, MLCC). All substitute parts listed maintain identical electrical specifications and physical package dimensions, ensuring direct functional replacement without circuit redesign.

Direct substitutes maintain all electrical and mechanical parameters identical to the main part. The upgrade substitute (CC0805ZKY5V8BB225) increases voltage rating to 25V while maintaining all other specifications, providing enhanced voltage margin for the same capacitance and package footprint.

Engineering Selection Recommendations

All listed direct substitutes are active production parts from established manufacturers (KEMET, YAGEO, Samsung Electro-Mechanics, KYOCERA AVX) with ROHS3 compliance and REACH unaffected status. These parts provide immediate availability and long-term supply continuity compared to the obsolete ECJ-2YF1C225Z.

Selection among direct substitutes should account for thickness variation within the 0805 package. YAGEO CC series parts (CC0805ZPY5V7BB225, CC0805ZRY5V7BB225) offer the thinnest profile at 0.037" (0.95mm), suitable for space-constrained applications. Samsung CL series parts maintain 0.053" (1.35mm) thickness, while KEMET and KYOCERA AVX options range from 0.055" to 0.057" (1.40mm to 1.45mm).

The upgrade substitute CC0805ZKY5V8BB225 (25V rating) is applicable where circuit design permits higher voltage margin without component substitution, maintaining identical capacitance, tolerance, temperature coefficient, and package footprint.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for ECJ-2YF1C225Z?

A: Yes. All direct substitute parts listed maintain identical electrical specifications (2.2 µF, 16V, Y5V, -20%/+80% tolerance) and 0805 package configuration. Physical thickness varies slightly between manufacturers but remains within acceptable PCB assembly tolerances for standard reflow processes.

Q: What is the difference between the direct substitutes and the upgrade part CC0805ZKY5V8BB225?

A: Direct substitutes maintain the 16V voltage rating of the original part. The upgrade part CC0805ZKY5V8BB225 increases voltage rating to 25V while preserving all other electrical and mechanical parameters. Use the upgrade part only if circuit design permits the higher voltage specification.

Q: Are all these parts RoHS compliant?

A: All active production substitutes listed are ROHS3 compliant and REACH unaffected. The original ECJ-2YF1C225Z (obsolete) does not specify RoHS status.

Q: Does thickness variation affect PCB assembly compatibility?

A: Thickness variation across the 0805 package (0.037" to 0.057") is within standard PCB assembly specifications. Verify specific thickness requirements against your PCB design and reflow profile if space constraints exist.

Q: Which substitute offers the best availability?

A: KGM21AV51C225ZU (KYOCERA AVX) shows the highest inventory at 21,659 pieces. C0805C225Z4VAC7800 (KEMET) provides 78,595 pieces. Both ensure immediate availability for production requirements.
