ECJ-0EF1E222Z Equivalent & Substitute Parts

Part Overview

The ECJ-0EF1E222Z is a 2200 pF ceramic capacitor manufactured by Panasonic Electronic Components, rated for 25V with Y5V temperature coefficient in 0402 (1005 Metric) surface mount package. This part is classified as Obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain the same capacitance value, package form factor, and voltage rating while accommodating variations in temperature coefficient and tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECJ-0EF1E222Z is determined by the following mandatory parameters:

• Capacitance Value: Must be 2200 pF (no tolerance variation acceptable)
• Package Form Factor: Must be 0402 (1005 Metric) for mechanical and electrical compatibility
• Voltage Rating: Must be ≥25V to maintain circuit safety margins
• Mounting Type: Must be Surface Mount, MLCC
• Moisture Sensitivity Level: Must be ≤1 (Unlimited)

Secondary parameters including temperature coefficient, tolerance, and operating temperature range may vary within acceptable engineering limits. Parts with higher voltage ratings (50V) and different temperature coefficients (X7R vs. Y5V) are acceptable substitutes provided they meet the mandatory criteria above.

Parameter Comparison

Engineering Selection Recommendations

UMK105B7222KV-F (Taiyo Yuden): This direct substitute provides identical capacitance and package specifications with elevated voltage rating (50V vs. 25V), offering improved safety margin. The X7R temperature coefficient provides superior stability compared to Y5V across the operating range. However, product status is "Not For New Designs," limiting suitability for new development. Inventory availability is 1450 units.

C0402C222K3RAC7867 (KEMET): This similar substitute maintains the 25V voltage rating and 0402 package while offering X7R temperature coefficient and ±10% tolerance. Product status is Active, making it suitable for both maintenance and new design applications. RoHS3 compliance and REACH unaffected status confirm regulatory alignment. Inventory availability is 440,267 units, providing superior supply continuity.

For new designs and long-term production continuity, C0402C222K3RAC7867 is the preferred selection. For existing designs requiring direct voltage-rated equivalents, UMK105B7222KV-F provides functional compatibility with enhanced performance margins.

Frequently Asked Questions (FAQ)

Q: Can UMK105B7222KV-F replace ECJ-0EF1E222Z in existing circuits?

A: Yes. The 50V rating of UMK105B7222KV-F exceeds the 25V requirement, providing additional safety margin. The X7R temperature coefficient offers improved capacitance stability across temperature extremes compared to Y5V. Physical dimensions and mounting characteristics are identical.

Q: What is the difference between Y5V and X7R temperature coefficients?

A: Y5V exhibits capacitance variation of -82% to +22% across -30°C to 85°C operating range. X7R exhibits ±15% variation across -55°C to 125°C. X7R provides superior stability but operates over a wider temperature range. Selection depends on circuit requirements for capacitance tolerance at operating temperatures.

Q: Why does C0402C222K3RAC7867 have ±10% tolerance while ECJ-0EF1E222Z has -20%, +80%?

A: Tolerance specifications reflect manufacturing process capabilities and design philosophy. The ±10% tolerance of C0402C222K3RAC7867 indicates tighter manufacturing control, providing more predictable capacitance values. The -20%, +80% tolerance of ECJ-0EF1E222Z is typical for Y5V dielectric materials. Both are acceptable for general purpose applications; circuit-specific requirements determine which is appropriate.

Q: Is the 0402 package identical across all three parts?

A: Yes. All three parts use 0402 (1005 Metric) package with identical physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum thickness of 0.022" (0.55mm). Direct mechanical substitution is possible without PCB redesign.

Q: What does "Not For New Designs" mean for UMK105B7222KV-F?

A: This designation indicates the manufacturer does not recommend this part for new product development. While functionally suitable for replacement in existing designs, long-term availability and support may be limited. For new designs, C0402C222K3RAC7867 with Active status is the recommended choice.

Q: Are all three parts RoHS compliant?

A: UMK105B7222KV-F and C0402C222K3RAC7867 are explicitly ROHS3 compliant. ECJ-0EF1E222Z RoHS status is not specified in available documentation. For applications requiring RoHS certification, substitute parts provide documented compliance.
