Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 04026D823KAT2A are qualified based on the following criteria:

Primary Matching Parameters:

• Capacitance: 0.082 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Size / Dimension: 0.039" L x 0.020" W (1.00mm x 0.50mm) (exact match required)
• Thickness (Max): 0.022" (0.55mm to 0.56mm acceptable)

Allowable Variations:

• Voltage - Rated: Equal to or greater than 6.3V (10V and 16V rated substitutes are acceptable)
• Temperature Coefficient: X5R or X7R (both maintain -55°C ~ 85°C minimum operating range; X7R extends to -55°C ~ 125°C)
• Manufacturer: KYOCERA AVX, KEMET, YAGEO, Murata Electronics
• Packaging: Tape & Reel (TR) format maintained across all substitutes
• RoHS Status: ROHS3 Compliant (all substitutes meet this requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (all substitutes meet this requirement)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Operating Characteristics): C0402C823K8PAC7867 (KEMET) and CC0402KRX5R6BB823 (YAGEO) are functionally equivalent to the 04026D823KAT2A, maintaining X5R temperature coefficient and -55°C ~ 85°C operating range while providing 10V rated voltage. Both parts are Active status and ROHS3 Compliant.

For Enhanced Voltage Margin: C0402C823K4RAC7867 (KEMET) and C0402C823K8RAC7867 (KEMET) provide higher voltage ratings (16V and 10V respectively) with X7R temperature coefficient, extending operating temperature to -55°C ~ 125°C. These are suitable where additional voltage headroom or wider temperature operation is required. Both are Active status and ROHS3 Compliant.

For Alternative Sourcing: CC0402KRX7R6BB823 (YAGEO) offers 10V X7R characteristics with extended temperature range (-55°C ~ 125°C) and is Active status with ROHS3 compliance.

Not Recommended for New Designs: GRM155R61A823KA01D (Murata Electronics) is marked "Not For New Designs" and should be avoided for new applications despite meeting electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can I use a 10V or 16V rated capacitor in place of the 6.3V rated 04026D823KAT2A? A: Yes. Higher voltage-rated capacitors are functionally compatible substitutes. The 10V and 16V rated alternatives maintain the same capacitance (0.082 µF), tolerance (±10%), and package dimensions (0402), providing additional voltage margin without affecting circuit operation at 6.3V or lower.

Q: What is the difference between X5R and X7R temperature coefficients? A: X5R maintains capacitance within ±15% across -55°C ~ 85°C operating range. X7R maintains capacitance within ±15% across -55°C ~ 125°C operating range. Both are acceptable substitutes for the 04026D823KAT2A, which specifies X5R. X7R provides extended temperature operation if required by the application.

Q: Are all substitute parts available in Tape & Reel (TR) packaging? A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) format, matching the original part's packaging specification.

Q: Why is GRM155R61A823KA01D listed if it is "Not For New Designs"? A: GRM155R61A823KA01D meets all electrical and mechanical substitution criteria but carries a "Not For New Designs" status from the manufacturer. It is included for reference in legacy system support or repair scenarios only. New designs should select from Active status alternatives.

Q: Do all substitute parts meet RoHS3 compliance? A: Yes. All listed substitute parts are ROHS3 Compliant and have Moisture Sensitivity Level 1 (Unlimited), matching the original part's compliance certifications.

Q: What is the physical size difference between substitute parts? A: All substitute parts maintain the same 0402 (1005 Metric) package with dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm). Thickness varies minimally between 0.022" (0.55mm) and 0.022" (0.56mm), which is within standard manufacturing tolerance and does not affect PCB assembly compatibility.
