Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECW-U2182KC9 is determined by strict equivalence in the following parameters: capacitance value (1800 pF), voltage rating (250V DC / 125V AC), dielectric material composition (Polyester, PEN, Metallized - Stacked), package type (1913 / 4833 Metric), mounting method (Surface Mount), and operating temperature range (-55°C to 125°C). The tolerance specification may vary within acceptable limits for the application. All substitute parts must maintain identical electrical performance under rated conditions and physical compatibility with the original PCB footprint.

Parameter Comparison

Engineering Selection Recommendations

The ECW-U2182JC9 serves as a direct substitute for the ECW-U2182KC9. Both parts are manufactured by Panasonic Electronic Components and maintain identical electrical specifications for capacitance, voltage rating, and operating temperature range. The substitute part features improved tolerance (±5% versus ±10%), providing tighter capacitance control. Both parts are Active status products with ROHS3 compliance and REACH unaffected designation, ensuring regulatory alignment. The physical dimensions are equivalent with negligible height variation (0.063" versus 0.067" seated height), maintaining PCB compatibility. Selection between these parts depends on tolerance requirements for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can ECW-U2182JC9 replace ECW-U2182KC9 in existing designs? A: Yes. Both parts share identical capacitance (1800 pF), voltage ratings (250V DC / 125V AC), dielectric material, package type (1913), and operating temperature range (-55°C to 125°C). The substitute features tighter tolerance (±5% versus ±10%) and is physically compatible with the original footprint.

Q: What is the difference between these two parts? A: The primary difference is tolerance specification. ECW-U2182KC9 has ±10% tolerance, while ECW-U2182JC9 has ±5% tolerance. The seated height differs by 0.004" (0.10mm), which does not affect PCB assembly compatibility.

Q: Are both parts ROHS3 compliant? A: Yes. Both ECW-U2182KC9 and ECW-U2182JC9 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the height difference affect PCB assembly? A: No. The height variation between parts (0.063" versus 0.067" seated height) is within standard PCB assembly tolerances and does not impact component placement or board-level functionality.

Q: Which part should be selected for new designs? A: For new designs, ECW-U2182JC9 is preferred due to its tighter ±5% tolerance, providing improved capacitance stability and circuit performance consistency.
