Substitute Part Grouping Explanation

Substitute parts for the ECJ-0EB1A823K are categorized based on strict electrical and mechanical parameter compatibility:

Direct Substitutes (Identical Parameters): Parts matching all critical parameters—0.082 µF capacitance, ±10% tolerance, 10V voltage rating, X5R temperature coefficient, 0402 package, and -55°C to 85°C operating range—are classified as direct substitutes. These parts maintain full functional equivalence.

Parametric Equivalents (X5R, 10V): Parts with identical capacitance, tolerance, voltage, and package but from different manufacturers fall into this category. All maintain X5R temperature stability and 10V rating.

Upgrades (Higher Voltage or X7R Coefficient): Parts rated at 16V or featuring X7R temperature coefficient (-55°C to 125°C) are functional upgrades. X7R provides wider temperature stability; 16V rating provides additional voltage margin. These are backward-compatible for 10V applications.

Compatibility Criteria:

Capacitance: 0.082 µF (fixed)
Tolerance: ±10% (fixed)
Package: 0402 (1005 Metric) (fixed)
Mounting: Surface Mount, MLCC (fixed)
Moisture Sensitivity: MSL 1 (fixed)

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): Select 0402ZD823KAT2A (KYOCERA AVX), 0402X823K100CT (Walsin Technology Corporation), or C0402C823K8PAC7867 (KEMET). All three maintain X5R temperature coefficient, 10V rating, and -55°C to 85°C operating range. All are active products with ROHS3 compliance and MSL 1 rating. KYOCERA AVX and Walsin parts offer the most direct functional equivalence.

For Enhanced Temperature Stability: Select C0402C823K8RAC7867 (KEMET), CC0402KRX7R6BB823 (YAGEO), or VJ0402Y823KXQCW1BC (Vishay Vitramon). These parts feature X7R temperature coefficient, extending operating range to -55°C to 125°C while maintaining 10V rating. All are active products with ROHS3 compliance.

For Voltage Margin Enhancement: Select C0402C823K4RAC7867 (KEMET) or CC0402KRX7R7BB823 (YAGEO). Both provide 16V rating with X7R temperature coefficient and -55°C to 125°C operating range. These are active products suitable for applications requiring additional voltage headroom.

Avoid for New Designs: GRM155R61A823KA01D and GRM155R71C823KA88D (Murata Electronics) are marked "Not For New Designs" and should not be selected for new production despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a 16V-rated capacitor in place of the 10V ECJ-0EB1A823K? A: Yes. A 16V-rated capacitor is electrically compatible in a 10V application. The higher voltage rating provides additional safety margin and does not affect circuit performance.

Q: What is the difference between X5R and X7R temperature coefficients? A: X5R maintains capacitance within ±15% across -55°C to 85°C. X7R maintains capacitance within ±15% across -55°C to 125°C. X7R provides wider temperature stability but both are suitable for the ECJ-0EB1A823K application range.

Q: Are all substitute parts RoHS3 compliant? A: All active substitute parts listed are ROHS3 compliant. The original ECJ-0EB1A823K (obsolete) does not specify RoHS status in the provided data.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance? A: No. Packaging format affects handling, storage, and automated assembly compatibility only. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Can I substitute the ECJ-0EB1A823K with a part from a different manufacturer? A: Yes, provided the substitute maintains identical capacitance (0.082 µF), tolerance (±10%), voltage rating (10V minimum), package (0402), and temperature coefficient (X5R minimum). All listed substitutes meet these criteria.

Q: Which substitute offers the best long-term availability? A: KEMET C0402C823K8PAC7867, YAGEO CC0402KRX7R6BB823, and KYOCERA AVX 0402ZD823KAT2A are all active products from established manufacturers with high inventory levels, providing reliable long-term sourcing.
