ECJ-0EF1E472Z Equivalent & Substitute Parts

Part Overview

The ECJ-0EF1E472Z is a 4700 pF ceramic capacitor manufactured by Panasonic Electronic Components, rated at 25V with Y5V temperature coefficient in 0402 (1005 Metric) surface mount package. This part is classified as Obsolete, making identification of equivalent and substitute components essential for ongoing production support, design updates, and inventory management. Substitute parts must maintain the same capacitance value, package footprint, and mounting characteristics while meeting or exceeding the original electrical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

Capacitance value: 4700 pF (exact match required)
Package / Case: 0402 (1005 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Compatibility Parameters:

Voltage Rating: Must equal or exceed 25V
Temperature Coefficient: Y5V or X7R acceptable (both provide adequate performance envelope)
Tolerance: ±10% or -20%, +80% acceptable
Operating Temperature Range: Must encompass or exceed -30°C ~ 85°C

Substitute parts are grouped by their relationship to the original specification: Direct equivalents maintain identical electrical characteristics; upgrades provide enhanced voltage ratings or improved temperature stability; similar parts offer functional compatibility with minor specification variations.

Engineering Selection Recommendations

For Direct Replacement (Existing Designs): KGM05AR71H472KH and C0402C472K3RAC7867 are suitable direct replacements. Both maintain 4700 pF capacitance and 0402 package compatibility. KGM05AR71H472KH provides upgraded 50V rating with X7R temperature coefficient and extended operating range (-55°C ~ 125°C), offering enhanced performance margin. C0402C472K3RAC7867 maintains 25V rating with X7R coefficient and equivalent operating range. Both are Active status components with ROHS3 compliance and high inventory availability.

For New Designs: 04025G472ZAT2A is recommended as the primary selection. This part maintains the original Y5V temperature coefficient and -30°C ~ 85°C operating range while providing upgraded 50V voltage rating. Active product status and ROHS3 compliance ensure long-term supply continuity and regulatory compliance.

For Extended Temperature Applications: KGM05AR71H472KH and TMK105B7472KV-F both offer -55°C ~ 125°C operating range with X7R temperature coefficient, providing superior stability across wider temperature extremes compared to the original Y5V specification.

Avoid for New Designs: TMK105B7472KV-F carries "Not For New Designs" status and should be used only for legacy system maintenance or existing production support.

Frequently Asked Questions (FAQ)

Q: Can KGM05AR71H472KH replace ECJ-0EF1E472Z in existing designs? A: Yes. Both parts share identical 4700 pF capacitance, 0402 package, and surface mount configuration. KGM05AR71H472KH provides higher 50V rating and X7R temperature coefficient, making it functionally superior for the same application space.

Q: What is the difference between Y5V and X7R temperature coefficients? A: Y5V exhibits -30%, +80% capacitance change across -30°C ~ 85°C operating range. X7R exhibits ±15% change across -55°C ~ 125°C range. X7R provides more stable capacitance across temperature but narrower tolerance band. Both are acceptable substitutes based on application requirements.

Q: Is 04025G472ZAT2A suitable for new product designs? A: Yes. This part is Active status with ROHS3 compliance, 50V rating, and Y5V temperature coefficient matching the original specification envelope. It is the recommended choice for new designs requiring ECJ-0EF1E472Z functionality.

Q: Why does TMK105B7472KV-F show "Not For New Designs" status? A: This designation indicates the manufacturer recommends against using this part in new product development. It remains available for legacy system support and existing production runs only.

Q: Are all substitute parts MSL 1 (Unlimited)? A: Yes. All listed substitute parts carry MSL 1 rating, matching the original part's moisture sensitivity classification and eliminating moisture handling concerns during assembly.

Q: Can I use a 50V rated capacitor in place of a 25V rated capacitor? A: Yes. Higher voltage ratings provide additional safety margin and are functionally compatible. KGM05AR71H472KH and 04025G472ZAT2A both offer 50V ratings suitable for 25V applications.

Q: What is the footprint compatibility between these parts? A: All listed parts use 0402 (1005 Metric) package with identical 0.039" L x 0.020" W (1.00mm x 0.50mm) dimensions and 0.022" (0.55mm) maximum thickness. PCB footprints are directly interchangeable.
