ECJ-0EB1C823K Equivalent & Substitute Parts

Part Overview

The ECJ-0EB1C823K is a 0.082 µF ±10% 16V ceramic capacitor in 0402 (1005 Metric) surface mount package manufactured by Panasonic Electronic Components. This part operates across -55°C to 85°C with X5R temperature coefficient and is classified as Obsolete. Due to its obsolete status and limited inventory (908 pcs), equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Critical Parameters (Must Match):

Capacitance: 0.082 µF
Voltage Rating: 16V
Package / Case: 0402 (1005 Metric)
Mounting Type: Surface Mount, MLCC
Moisture Sensitivity Level: MSL 1

Allowable Variations:

Temperature Coefficient: X5R or X7R (both acceptable; X7R provides extended operating range to 125°C)
Tolerance: ±10% or ±5% (tighter tolerance acceptable)
Product Status: Active preferred over Obsolete or Not For New Designs

The substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Equivalent (GRM155R71C823KA88D): Murata part with identical electrical specifications except temperature coefficient (X7R vs. X5R) and extended operating range.
Upgrade Parts (C0402C823J4RAC7867, C0402C823K4RAC7867, CC0402KRX7R7BB823): KEMET and YAGEO parts with X7R temperature coefficient and Active product status. C0402C823J4RAC7867 offers tighter ±5% tolerance.
Parametric Equivalent (0402X823K160CT): Walsin part matching X5R temperature coefficient and operating range of the original part.

Engineering Selection Recommendations

For New Designs: Select from Active status parts: C0402C823K4RAC7867 (KEMET), C0402C823J4RAC7867 (KEMET with ±5% tolerance), or CC0402KRX7R7BB823 (YAGEO). All three offer extended operating temperature range (-55°C to 125°C) and ROHS3 compliance. C0402C823K4RAC7867 provides the highest inventory availability (44570 pcs).

For Existing Designs Operating Within -55°C to 85°C: 0402X823K160CT (Walsin) maintains identical X5R temperature coefficient and operating range as the original ECJ-0EB1C823K while offering Active product status and ROHS3 compliance.

For Extended Temperature Performance: GRM155R71C823KA88D (Murata), C0402C823J4RAC7867, C0402C823K4RAC7867, or CC0402KRX7R7BB823 provide X7R temperature coefficient with -55°C to 125°C operating range. Note that Murata part carries "Not For New Designs" status.

All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 with identical HTSUS code (8532.24.0020).

Frequently Asked Questions (FAQ)

Q: Can I substitute ECJ-0EB1C823K with a part having X7R temperature coefficient instead of X5R?

A: Yes. X7R temperature coefficient is acceptable as a substitute. X7R provides a wider operating temperature range (-55°C to 125°C) compared to X5R (-55°C to 85°C). If your application operates only within -55°C to 85°C, both coefficients are functionally equivalent. X7R offers additional thermal margin for demanding environments.

Q: What is the difference between ±10% and ±5% tolerance parts?

A: Both tolerances are acceptable substitutes. ±5% tolerance (C0402C823J4RAC7867) provides tighter capacitance accuracy, beneficial for precision filtering or timing circuits. ±10% tolerance parts are suitable for general-purpose bypass and decoupling applications where capacitance variation has minimal impact on circuit performance.

Q: Are all substitute parts compatible with existing PCB layouts?

A: Yes. All substitute parts share identical package specifications: 0402 (1005 Metric) with dimensions 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum thickness 0.022" (0.55mm). No PCB redesign is required.

Q: Which substitute part has the best long-term availability?

A: C0402C823K4RAC7867 (KEMET) with 44570 pcs in stock and Active product status offers the strongest availability profile. CC0402KRX7R7BB823 (YAGEO) with 30839 pcs is also well-stocked. Both manufacturers actively support this specification.

Q: Do all parts meet RoHS and REACH requirements?

A: All substitute parts are ROHS3 compliant and REACH unaffected. The original ECJ-0EB1C823K does not specify RoHS status due to its Obsolete classification, but all active substitutes meet current environmental compliance standards.
