ECH-U1473JC9 Equivalent & Substitute Parts

Part Overview

The ECH-U1473JC9 is a 0.047 µF film capacitor manufactured by Panasonic Electronic Components, designed for general-purpose applications requiring stable capacitance and low dielectric loss. This surface-mount component features a polyphenylene sulfide (PPS) metallized-stacked dielectric with a 100V DC voltage rating and ±5% tolerance. The part is active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial electronics requiring reliable energy storage and filtering functions.

Substitute parts are identified when equivalent electrical performance can be maintained across critical parameters while meeting or exceeding the original specification requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the ECH-U1473JC9 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.047 µF (exact match required)
• Voltage rating: 100V DC minimum (equal or higher acceptable)
• Dielectric material: Polyphenylene Sulfide (PPS), Metallized - Stacked (exact match required)
• Package / Case: 2416 (6041 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 105°C minimum (equal or wider range acceptable)
• Termination: Solder Pads (exact match required)
• RoHS compliance: ROHS3 Compliant (equal or higher standard acceptable)

Tolerance may vary within acceptable engineering limits when the substitute part meets or exceeds the original specification. The ECH-U1473GC9 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The ECH-U1473GC9 is a qualified substitute for the ECH-U1473JC9. Both parts are manufactured by Panasonic Electronic Components and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part features improved tolerance performance (±2% versus ±5%), which represents an enhancement to the original specification without introducing any compatibility concerns.

Both parts carry active production status, full RoHS3 compliance, and REACH unaffected designation, ensuring regulatory compliance and long-term supply availability. The identical package footprint, mounting type, and termination method guarantee direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1473GC9 be used as a direct replacement for ECH-U1473JC9?

A: Yes. The ECH-U1473GC9 meets all electrical and mechanical requirements for direct substitution. Both parts share identical capacitance, voltage ratings, dielectric material, package dimensions, and operating temperature range. The substitute part's improved tolerance specification (±2%) exceeds the original requirement (±5%).

Q: What is the difference between these two parts?

A: The primary difference is tolerance specification. The ECH-U1473JC9 carries ±5% tolerance, while the ECH-U1473GC9 carries ±2% tolerance. This represents improved capacitance accuracy in the substitute part. All other electrical and mechanical parameters remain identical.

Q: Are there any board-level compatibility issues?

A: No. Both parts use the identical 2416 (6041 Metric) package with matching footprint dimensions (6.00mm x 4.10mm length and width, 2.60mm maximum seated height). Surface-mount solder pad termination is identical, enabling direct PCB compatibility without layout modifications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both ECH-U1473JC9 and ECH-U1473GC9 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory compliance is equivalent across both parts.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across the temperature range of -55°C to 105°C, providing consistent performance across industrial and commercial application environments.
