Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 04026D823MAT2A are qualified based on the following criteria:

Primary Matching Parameters:

• Capacitance: 0.082 µF (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) (exact match required)

Allowable Variations:

• Tolerance: ±10% or ±20% (tighter tolerance acceptable)
• Voltage Rating: 6.3V or higher (higher voltage acceptable for same or lower capacitance)
• Temperature Coefficient: X5R or X7R (both acceptable for general-purpose applications)
• Operating Temperature Range: -55°C ~ 85°C or -55°C ~ 125°C (extended range acceptable)
• Manufacturer: KEMET, YAGEO, Murata Electronics (qualified alternatives)
• RoHS Status: ROHS3 Compliant (required)
• MSL: 1 (Unlimited) (required)

Substitutes are organized by voltage rating and temperature coefficient to facilitate selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Active Status): KEMET C0402C823K8PAC7867 and C0402C823K8RAC7867, along with YAGEO CC0402KRX5R6BB823 and CC0402KRX7R6BB823, are qualified substitutes with Active product status. These parts maintain the 0402 package and 0.082 µF capacitance while offering improved tolerance (±10%) and extended voltage ratings or temperature ranges. Selection between X5R and X7R temperature coefficients depends on application thermal stability requirements.

Higher Voltage Alternatives (Active Status): KEMET C0402C823K4RAC7867 and C0402C823M4RAC7867 provide 16V ratings with X7R temperature coefficient and extended operating temperature range (-55°C ~ 125°C), suitable for applications requiring higher voltage margins or broader thermal performance.

Legacy Consideration: Murata Electronics GRM155R61A823KA01D is marked as Not For New Designs and should be avoided for new product development, though it remains electrically compatible for existing applications requiring continuity.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) ratings, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 04026D823MAT2A with a higher voltage-rated part? A: Yes. Higher voltage ratings are acceptable substitutes. For example, the 16V-rated KEMET C0402C823K4RAC7867 or C0402C823M4RAC7867 are direct substitutes for the 6.3V original part. Higher voltage ratings provide additional safety margin without affecting capacitance or package compatibility.

Q: What is the difference between X5R and X7R temperature coefficients? A: Both X5R and X7R are acceptable for this 0.082 µF 0402 application. X5R maintains capacitance within ±15% across -55°C to 85°C. X7R maintains capacitance within ±15% across -55°C to 125°C, offering extended temperature stability. Selection depends on application thermal requirements.

Q: Are tolerance differences significant for this capacitor value? A: The original part specifies ±20% tolerance. Substitute parts with ±10% tolerance offer tighter capacitance control and are directly compatible. Tighter tolerance does not create compatibility issues and may improve circuit performance in applications sensitive to capacitance variation.

Q: Can I use parts from different manufacturers interchangeably? A: Yes. KYOCERA AVX, KEMET, YAGEO, and Murata Electronics parts listed are electrically and mechanically equivalent when matching the specified parameters (0.082 µF, 0402 package, appropriate voltage and temperature coefficient). All are ROHS3 compliant with MSL 1 rating.

Q: Why is the Murata GRM155R61A823KA01D marked "Not For New Designs"? A: This part is in legacy status and may have limited future availability. For new product designs, select from Active-status alternatives such as KEMET or YAGEO equivalents to ensure long-term supply continuity.

Q: Does package thickness variation affect PCB assembly? A: The original part specifies 0.022" (0.56mm) maximum thickness. Substitute parts specify 0.022" (0.55mm) maximum thickness. This minimal variation does not affect PCB assembly, reflow soldering, or component placement.

Q: Are all listed parts available in Tape & Reel packaging? A: The original 04026D823MAT2A is specified with standard packaging. Substitute parts from KEMET, YAGEO, and Murata are available in Tape & Reel (TR) format, which is standard for high-volume surface-mount assembly.
