ECJ-0EF1C473Z Equivalent & Substitute Parts

Part Overview

The ECJ-0EF1C473Z is a 0.047 µF ceramic capacitor rated at 16V with Y5V temperature coefficient in 0402 (1005 Metric) surface mount package. This part is classified as obsolete, making identification of active equivalent components essential for ongoing production and design continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance value (0.047 µF), tolerance band (-20%, +80%), voltage rating (16V), temperature coefficient (Y5V), operating temperature range (-30°C ~ 85°C), package designation (0402), and physical dimensions (1.00mm x 0.50mm x 0.55mm max thickness). All identified substitute parts meet these criteria and are manufactured by active component suppliers with current production status.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with ECJ-0EF1C473Z? A: Yes. All substitute parts share identical electrical specifications (0.047 µF, 16V, Y5V) and mechanical dimensions (0402 package, 1.00mm x 0.50mm x 0.55mm), enabling direct replacement without circuit modification.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging is optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging is supplied in smaller quantities on carrier tape and is suitable for lower-volume or manual assembly operations.

Q: Are all substitute parts RoHS compliant? A: Yes. All active substitute parts carry ROHS3 compliance certification and are REACH unaffected.

Q: Does the obsolete status of ECJ-0EF1C473Z affect circuit performance? A: No. Obsolescence indicates discontinued production. Electrical and mechanical performance remain unchanged. Active substitute parts provide equivalent functionality with ongoing manufacturing support.

Q: Which substitute part has the best availability? A: CC0402ZRY5V7BB473 (YAGEO) has the highest inventory level at 156,286 pcs in stock.
