Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-P1H563GZ is determined by the following critical parameters:

• Capacitance Value: 0.056 µF (exact match required)
• Tolerance: ±2% (maintains circuit design specifications)
• Voltage Rating - DC: 50V minimum (ensures safe operation margin)
• Capacitance Tolerance: ±2% (circuit-critical specification)

The ECH-U1H563GX9 meets the primary electrical requirements of capacitance and voltage rating. However, this substitute introduces significant differences in dielectric material (Polyphenylene Sulfide vs. Polypropylene), mounting technology (Surface Mount vs. Through Hole), and operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C). These differences must be evaluated within the context of the specific application circuit.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1H563GX9 provides electrical equivalence in capacitance and DC voltage rating. Selection of this substitute requires consideration of the following factors:

Mounting Technology Transition: The ECQ-P1H563GZ is a through-hole radial component, while the ECH-U1H563GX9 is a surface-mount device. Direct board-level substitution is not possible without circuit board redesign and rework.

Dielectric Material Difference: The main part uses polypropylene dielectric; the substitute uses polyphenylene sulfide with metallized-stacked construction. These materials exhibit different frequency response, ESR characteristics, and aging profiles. Application-specific performance validation is required.

Temperature Operating Range: The substitute supports an extended operating temperature range (-55°C ~ 125°C) compared to the main part (-40°C ~ 85°C), providing broader environmental compatibility.

Compliance Status: The ECH-U1H563GX9 is ROHS3 compliant and carries active product status, ensuring ongoing availability and regulatory alignment. The main part is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the ECH-U1H563GX9 be directly soldered into a board designed for the ECQ-P1H563GZ?

A: No. The ECQ-P1H563GZ is a through-hole radial component with PC pins and 0.197" lead spacing. The ECH-U1H563GX9 is a surface-mount device with solder pads in 1913 (4833 Metric) package. Direct substitution requires circuit board redesign and component placement modification.

Q: Are the electrical characteristics identical between these two parts?

A: Both parts share identical capacitance (0.056 µF), tolerance (±2%), and DC voltage rating (50V). However, the dielectric materials differ significantly. Polypropylene and polyphenylene sulfide exhibit different frequency response, temperature coefficients, and ESR characteristics. Circuit performance validation is necessary for applications sensitive to these parameters.

Q: What is the significance of the extended temperature range in the ECH-U1H563GX9?

A: The substitute operates from -55°C to 125°C, compared to the main part's -40°C to 85°C range. This extended range provides compatibility with broader environmental conditions and industrial applications. If the original circuit operates within -40°C to 85°C, the substitute's extended range presents no limitation.

Q: Is the ECH-U1H563GX9 suitable for high-frequency and switching applications?

A: The ECH-U1H563GX9 is specified for general-purpose applications, whereas the ECQ-P1H563GZ is designated for high-frequency and switching use. Application-specific frequency response and transient performance characteristics must be evaluated before substitution in frequency-sensitive circuits.

Q: What compliance certifications apply to the ECH-U1H563GX9?

A: The ECH-U1H563GX9 is ROHS3 compliant, REACH unaffected, and carries EAR99 ECCN classification. The main part's compliance status is not specified in available documentation.
