Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECH-U1C822JB5 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 8200 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage ratings: 16V DC / 11V AC (exact match required)
• Dielectric material: Polyphenylene Sulfide (PPS), Metallized - Stacked (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Termination: Solder Pads (exact match required)

The ECH-U1C822JX5 qualifies as a direct substitute based on full alignment with all critical electrical and mechanical parameters. Both parts belong to the Panasonic ECH-U series and share identical functional specifications. The primary distinction lies in series designation (B-series versus X-series) and compliance certifications.

Engineering Selection Recommendations

The ECH-U1C822JX5 serves as a direct functional equivalent to the ECH-U1C822JB5 across all critical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and supply availability:

ECH-U1C822JB5 is appropriate for applications where RoHS non-compliance is acceptable or where legacy design specifications mandate this exact part number.

ECH-U1C822JX5 is the preferred choice for new designs and applications requiring ROHS3 compliance. This variant offers superior regulatory alignment and significantly higher inventory availability (4788 units versus 832 units), reducing supply chain risk. The marginal height difference (0.051" versus 0.047") remains within standard PCB assembly tolerances and does not impact functional performance or board-level compatibility.

Both parts maintain identical electrical performance, temperature stability, and moisture sensitivity characteristics. Selection should prioritize compliance requirements and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can ECH-U1C822JX5 be used as a direct replacement for ECH-U1C822JB5 in existing designs?

A: Yes. The ECH-U1C822JX5 is electrically and mechanically equivalent across all functional parameters. The 0.004" (0.10mm) height difference falls within standard PCB assembly tolerances and does not affect circuit performance or board-level fit.

Q: What is the primary difference between these two parts?

A: The main differences are RoHS compliance status (ECH-U1C822JX5 is ROHS3 compliant while ECH-U1C822JB5 is non-compliant) and inventory availability. Both parts are functionally identical in capacitance, voltage rating, temperature range, and dielectric material.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and maintain the same electrical specifications including capacitance value, tolerance, and voltage ratings.

Q: Which part should be selected for new product designs?

A: ECH-U1C822JX5 is recommended for new designs due to ROHS3 compliance and higher inventory availability, ensuring better long-term supply chain stability.

Q: Is the package footprint identical between these parts?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" x 0.049"). The seated height differs by 0.004" (0.10mm), which is negligible for standard surface-mount assembly processes.
