ECJ-2FF1E474Z Equivalent & Substitute Parts

Part Overview

The Panasonic ECJ-2FF1E474Z is a 0.47 µF ceramic capacitor rated at 25V with Y5V temperature coefficient in 0805 (2012 Metric) surface mount package. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Direct replacements are available from multiple active manufacturers with identical electrical specifications and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution for ECJ-2FF1E474Z is determined by strict equivalence across the following parameters:

Capacitance: 0.47 µF (exact match required)
Tolerance: -20%, +80% (exact match required)
Voltage Rating: 25V (exact match for direct substitutes)
Temperature Coefficient: Y5V (F) (exact match required)
Operating Temperature: -30°C ~ 85°C (exact match required)
Package: 0805 (2012 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Moisture Sensitivity: 1 (Unlimited) (exact match required)

Direct substitutes maintain all electrical and mechanical parameters. One upgrade option (CC0805ZRY5V9BB474) increases voltage rating to 50V while maintaining all other specifications, providing enhanced voltage margin for the same footprint.

Engineering Selection Recommendations

All listed direct substitutes (C0805C474Z3VAC7800, CC0805ZPY5V8BB474, CC0805ZRY5V8BB474, CL21F474ZACNNNC, KGM21CV51E474ZL, KGM21CV51E474ZU) are active products with ROHS3 compliance and REACH unaffected status, providing long-term supply continuity. These parts are electrically and mechanically equivalent to the obsolete ECJ-2FF1E474Z.

KGM21CV51E474ZU offers the highest inventory availability (10779 Pcs) among direct substitutes. CC0805ZRY5V8BB474 provides the second-highest availability (8984 Pcs) with Cut Tape and Digi-Reel packaging options.

CC0805ZRY5V9BB474 functions as an upgrade option, increasing voltage rating to 50V while maintaining identical capacitance, tolerance, temperature coefficient, and package specifications. This upgrade is suitable for applications requiring enhanced voltage margin without footprint or thermal profile changes.

Frequently Asked Questions (FAQ)

Q: Can I use CC0805ZRY5V9BB474 (50V) as a direct replacement for ECJ-2FF1E474Z (25V)?

A: Yes. CC0805ZRY5V9BB474 is electrically and mechanically compatible. The higher voltage rating (50V vs 25V) does not affect circuit operation in applications designed for 25V operation. The 0805 package, capacitance, tolerance, and temperature coefficient remain identical.

Q: What is the difference between CC0805ZPY5V8BB474 and CC0805ZRY5V8BB474?

A: Both are YAGEO CC series 0.47 µF 25V Y5V 0805 capacitors with identical electrical specifications. CC0805ZPY5V8BB474 is supplied in Tape & Reel (TR) packaging, while CC0805ZRY5V8BB474 is supplied in Cut Tape (CT) & Digi-Reel packaging. Selection depends on assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original ECJ-2FF1E474Z (obsolete) does not specify RoHS status in available data.

Q: Does thickness variation affect PCB assembly?

A: Thickness variations among substitutes (0.035" to 0.055") are within standard 0805 package tolerances. All parts are compatible with standard 0805 footprints and reflow profiles. Verify specific assembly equipment clearance if height-constrained applications exist.

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

A: KGM21CV51E474ZU (KYOCERA AVX) provides the highest current inventory (10779 Pcs) and is an active product with established supply chain presence, supporting long-term production requirements.
