ECJ-2VB1C154K Equivalent & Substitute Parts

Part Overview

The ECJ-2VB1C154K is a 0.15 µF ±10% 16V ceramic capacitor with X7R temperature coefficient in 0805 (2012 Metric) surface mount package manufactured by Panasonic Electronic Components. This part is classified as obsolete, making substitute components necessary for new designs and ongoing production support. The X7R dielectric and 0805 form factor are standard specifications widely available across multiple manufacturers, enabling direct functional replacement with active production alternatives.

Substitute Part Grouping Explanation

Substitution for the ECJ-2VB1C154K is determined by strict equivalence across the following parameters:

Capacitance: 0.15 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage Rating: 16V minimum (equal or higher voltage ratings are acceptable)
Temperature Coefficient: X7R (exact match required)
Operating Temperature: -55°C ~ 125°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 meet these criteria. One substitute part, GRM21BR71E154KA01L, carries a 25V voltage rating instead of 16V; this part remains functionally compatible as the higher voltage rating provides additional design margin while maintaining all other electrical and mechanical specifications.

Engineering Selection Recommendations

For new designs, select from parts with Active product status. The following manufacturers offer 0.15 µF 16V X7R 0805 ceramic capacitors in active production:

KEMET C0805C154K4RAC7800 provides the highest inventory availability (12015 Pcs) and is specified for bypass and decoupling applications. YAGEO CC0805KRX7R7BB154 offers 10428 Pcs in stock. KYOCERA AVX provides multiple active options: 0805YC154KAT9ZM (948 Pcs), KGM21ER71C154KL (966 Pcs), and KGM21ER71C154KU (1270 Pcs). Samsung Electro-Mechanics CL21B154KOANNNC and CL21B154KOANNND each provide approximately 700-980 Pcs. Vishay Vitramon VJ0805Y154KXJRW1BC and VJ0805Y154KXJTW1BC each offer approximately 800 Pcs.

All active production substitutes carry RoHS3 compliance and REACH Unaffected status. GRM21BR71E154KA01L from Murata Electronics is classified as Not For New Designs and should be avoided for new product development, though it remains functionally compatible due to its higher 25V voltage rating.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than 16V?

A: Yes. A higher voltage rating provides additional design margin and does not compromise circuit function. GRM21BR71E154KA01L at 25V is electrically compatible with the 16V specification of the ECJ-2VB1C154K.

Q: Are all substitute parts pin-compatible with the ECJ-2VB1C154K?

A: Yes. All substitute parts use the 0805 (2012 Metric) surface mount package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm nominal). Physical placement and soldering procedures remain unchanged.

Q: What is the significance of the X7R temperature coefficient?

A: X7R specifies a temperature coefficient of ±15% capacitance change across the -55°C to 125°C operating range. This is a standard specification for general-purpose ceramic capacitors. All substitute parts maintain this same temperature coefficient.

Q: Why is GRM21BR71E154KA01L marked as Not For New Designs?

A: This designation indicates the manufacturer has discontinued active development and support for this part. While functionally compatible, new designs should select from parts with Active status to ensure long-term supply chain stability and manufacturer support.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts carry Moisture Sensitivity Level 1 (Unlimited), matching the ECJ-2VB1C154K specification. This indicates no special moisture handling precautions are required during storage or assembly.

Q: What packaging options are available for these substitute parts?

A: Substitute parts are available in Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, or unspecified packaging. Select packaging based on assembly process requirements. Tape & Reel is standard for automated pick-and-place assembly.
