Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-U2153KC9 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.015 µF (no deviation permitted)
• Voltage Rating: Must maintain minimum 250V DC and 125V AC ratings
• Dielectric Type: Must utilize polyester and polyethylene naphthalate (PEN) metallized-stacked construction
• Package Format: Must conform to 1913 (4833 Metric) dimensions and surface-mount configuration
• Mounting Technology: Must be compatible with solder pad termination on PCB assembly equipment
• Temperature Range: Must support -55°C to 125°C operating envelope
• Compliance Standards: Must maintain ROHS3 and REACH compliance status

The ECW-U2153JC9 qualifies as a direct substitute based on matching all electrical and mechanical parameters. The primary distinction is tolerance specification, where the substitute offers improved tolerance performance (±5% versus ±10%), representing an upgrade path for applications requiring tighter capacitance control.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-U2153KC9 and ECW-U2153JC9 maintain Active product status with full ROHS3 compliance and REACH unaffected designation, confirming long-term availability and regulatory suitability for current manufacturing standards.

The ECW-U2153JC9 represents an upgrade option where circuit design permits tolerance improvement. The ±5% tolerance specification provides enhanced capacitance stability compared to the ±10% tolerance of the primary part, benefiting applications with stringent frequency response or filtering requirements. Both parts share identical electrical ratings, dielectric composition, and thermal operating range, ensuring functional interchangeability within the specified parameter envelope.

Height variation between parts (0.063" versus 0.067" maximum seated height) remains within typical PCB assembly clearance tolerances and does not restrict substitution in standard surface-mount applications.

Frequently Asked Questions (FAQ)

Q: Can ECW-U2153JC9 be used as a direct replacement for ECW-U2153KC9?

A: Yes. Both parts share identical capacitance (0.015 µF), voltage ratings (250V DC / 125V AC), dielectric material, package format (1913 / 4833 Metric), and operating temperature range (-55°C to 125°C). The substitute offers improved tolerance performance (±5% versus ±10%), making it functionally compatible for all applications where the primary part is specified.

Q: What is the significance of tolerance differences between these parts?

A: Tolerance defines the allowable deviation from the nominal capacitance value. The ECW-U2153KC9 permits ±10% variation (0.0135 µF to 0.0165 µF), while the ECW-U2153JC9 restricts variation to ±5% (0.01425 µF to 0.01575 µF). Applications requiring precise capacitance values benefit from the tighter tolerance of the substitute part.

Q: Are there mechanical compatibility concerns between these parts?

A: Both parts conform to the 1913 (4833 Metric) package with identical length and width dimensions (0.189" x 0.130" / 4.80mm x 3.30mm). Maximum seated height differs by 0.004" (0.10mm), which does not impact standard PCB assembly processes or clearance requirements.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both ECW-U2153KC9 and ECW-U2153JC9 are ROHS3 compliant and REACH unaffected, confirming compliance with current environmental and hazardous substance regulations applicable to electronic components.

Q: What is the supply status of these parts?

A: Both parts maintain Active product status. The ECW-U2153JC9 shows higher inventory availability (2782 pcs) compared to the ECW-U2153KC9 (898 pcs), which may influence procurement decisions for high-volume applications.
