ECJ-2YF1C155Z Equivalent & Substitute Parts

Part Overview

The ECJ-2YF1C155Z is a 1.5 µF ceramic capacitor rated at 16V with Y5V temperature coefficient in 0805 (2012 Metric) surface mount package, manufactured by Panasonic Electronic Components. This part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications. The part is suitable for general-purpose applications requiring stable capacitance across the -30°C to 85°C operating temperature range.

Substitute Part Grouping Explanation

Substitution for the ECJ-2YF1C155Z is determined by strict equivalence across the following critical parameters:

Capacitance: 1.5 µF (exact match required)
Tolerance: -20%, +80% (exact match required)
Voltage Rating: 16V (exact match required)
Temperature Coefficient: Y5V (F) (exact match required)
Operating Temperature Range: -30°C ~ 85°C (exact match required)
Package / Case: 0805 (2012 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the original part.

Engineering Selection Recommendations

All listed substitute parts are active production components from established manufacturers with RoHS3 compliance and REACH unaffected status, providing long-term supply assurance compared to the obsolete ECJ-2YF1C155Z. Selection among substitutes should prioritize inventory availability and lead time requirements for your application timeline.

The KEMET C0805C155Z4VAC7800 offers the highest inventory level (13344 Pcs) and the thinnest profile (0.88mm), making it suitable for space-constrained designs. The YAGEO CC0805ZRY5V7BB155 provides the second-highest inventory (24588 Pcs) and maintains standard dimensional specifications. The Samsung Electro-Mechanics variants (CL21F155ZOFNNNE and CL21F155ZOFNNNG) offer intermediate inventory levels with 1.35mm thickness specifications.

All substitute parts maintain identical electrical specifications and package footprint compatibility with the original ECJ-2YF1C155Z, ensuring direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the ECJ-2YF1C155Z?

A: Yes. All listed substitute parts meet the identical electrical and mechanical specifications: 1.5 µF capacitance, -20%/+80% tolerance, 16V rating, Y5V temperature coefficient, -30°C to 85°C operating range, 0805 package, and MSL 1 rating. They are direct functional equivalents.

Q: What is the difference between the Samsung CL21F155ZOFNNNE and CL21F155ZOFNNNG variants?

A: Both parts are electrically and mechanically identical with the same specifications and 1.35mm thickness. The difference lies in their internal coding or manufacturing batch designation, but they are functionally equivalent for circuit applications.

Q: Does thickness variation among substitutes affect PCB assembly?

A: Thickness variations (0.88mm to 1.40mm) are within standard 0805 package tolerances and do not affect PCB assembly compatibility. All parts mount to the same footprint and reflow profile. Verify your specific design constraints if height clearance is critical.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts listed carry RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: Which substitute offers the best long-term availability?

A: The YAGEO CC0805ZRY5V7BB155 and KEMET C0805C155Z4VAC7800 offer the highest inventory levels (24588 Pcs and 13344 Pcs respectively) and active production status, providing superior long-term supply assurance.
