ECJ-0EF1E102Z Equivalent & Substitute Parts

Part Overview

The ECJ-0EF1E102Z is a 1000 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, making identification of equivalent and substitute components necessary for ongoing production support, design updates, and inventory management. Substitute parts must maintain electrical compatibility across capacitance, voltage rating, and temperature coefficient specifications while accommodating packaging and availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECJ-0EF1E102Z is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 1000 pF (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)

Allowable Parameter Variations:

• Voltage - Rated: Equal to or greater than 25V
• Temperature Coefficient: Y5V or equivalent performance range
• Tolerance: Equal to or tighter than -20%, +80%
• Operating Temperature Range: Must encompass or exceed -30°C ~ 85°C
• Moisture Sensitivity Level: MSL 1 or better

The substitute parts listed below meet these criteria and are therefore electrically and mechanically compatible with the ECJ-0EF1E102Z for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

04023G102ZAT2A (KYOCERA AVX) is the primary substitute for ECJ-0EF1E102Z. This part maintains identical electrical specifications (1000 pF, -20%/+80% tolerance, 25V, Y5V temperature coefficient) and mechanical compatibility (0402 package). The part is currently Active in production status, ensuring long-term availability. ROHS3 compliance and REACH Unaffected certification satisfy regulatory requirements for new designs and manufacturing environments. Packaging in Tape & Reel format supports automated assembly processes.

GRM155R71H102KA01D (Murata Electronics) is a secondary substitute with enhanced electrical performance characteristics. The 50V voltage rating provides additional design margin above the 25V requirement. X7R temperature coefficient offers superior temperature stability compared to Y5V, with an expanded operating range of -55°C ~ 125°C. Tolerance is tightened to ±10%, improving capacitance accuracy. The part carries ROHS3 compliance and REACH Unaffected status. However, the product status is classified as Not For New Designs, limiting its suitability for new development initiatives. This part is appropriate for legacy system support or applications where enhanced performance margins are beneficial.

Frequently Asked Questions (FAQ)

Q: Can GRM155R71H102KA01D replace ECJ-0EF1E102Z in all applications?

A: GRM155R71H102KA01D is electrically compatible as a substitute. The higher voltage rating (50V vs. 25V) and superior temperature stability (X7R vs. Y5V) provide enhanced performance margins. However, the product status "Not For New Designs" indicates this part is not recommended for new development. For new designs, 04023G102ZAT2A is the preferred choice.

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

A: Y5V and X7R are temperature coefficient classifications for ceramic capacitors. Y5V exhibits capacitance change of -82% to +22% over the operating temperature range, suitable for general-purpose applications. X7R provides tighter capacitance stability of ±15% over -55°C to 125°C, making it suitable for applications requiring higher precision. Selection depends on circuit requirements for capacitance stability across temperature variations.

Q: Are all substitute parts available in the same packaging format?

A: All three parts use 0402 (1005 Metric) surface mount packages with compatible physical dimensions. Packaging format for supply differs: ECJ-0EF1E102Z packaging is not specified, 04023G102ZAT2A is supplied in Tape & Reel (TR), and GRM155R71H102KA01D is supplied in Cut Tape (CT) & Digi-Reel®. Verify packaging compatibility with your assembly process requirements.

Q: Why is the ECJ-0EF1E102Z classified as Obsolete?

A: Obsolete status indicates the part is no longer in active production by the manufacturer. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. Substitution with active production parts (04023G102ZAT2A) is recommended for designs requiring extended component availability and supply chain stability.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: 04023G102ZAT2A and GRM155R71H102KA01D are both ROHS3 Compliant and REACH Unaffected. Compliance status for the original ECJ-0EF1E102Z is not specified in available documentation. Verify compliance requirements with your regulatory and procurement departments before finalizing component selection.
