22201C684MAT1A Equivalent & Substitute Parts

Part Overview

The 22201C684MAT1A is a 0.68 µF ceramic capacitor manufactured by KYOCERA AVX with a rated voltage of 100V and X7R temperature coefficient. This surface mount multilayer ceramic capacitor (MLCC) in 2220 package format is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant.

Substitute parts become necessary when the original manufacturer part is unavailable, when design requirements change to accommodate higher voltage ratings or tighter tolerances, or when alternative sourcing improves supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 22201C684MAT1A are grouped based on the following substitution criteria:

Direct Substitutes (Same Electrical Specifications): Parts maintaining identical capacitance (0.68 µF), voltage rating (100V), temperature coefficient (X7R), and package format (2220) are classified as direct substitutes. These parts differ only in manufacturer, tolerance, or product status.

Upgrade Substitutes (Enhanced Specifications): Parts with improved electrical characteristics—specifically higher voltage ratings (250V) or tighter tolerances (±10% versus ±20%)—while maintaining the same capacitance value, temperature coefficient, and package format. These upgrades provide enhanced performance margins and are suitable for applications requiring greater reliability or voltage headroom.

Key Parameters Determining Substitutability:

• Capacitance value: 0.68 µF (fixed)
• Temperature coefficient: X7R (fixed)
• Package format: 2220 (5750 Metric) (fixed)
• Mounting type: Surface Mount, MLCC (fixed)
• Operating temperature range: -55°C to 125°C (fixed)
• Voltage rating: 100V minimum (100V or higher acceptable)
• Tolerance: ±20% or tighter acceptable

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): The C5750X7R2A684M160KA from TDK Corporation provides direct electrical equivalence with identical 0.68 µF capacitance, ±20% tolerance, and 100V rating. However, this part carries "Not For New Designs" status. It remains suitable for legacy system maintenance and repair applications where the original specification must be preserved. The reduced thickness (0.071" versus 0.090") may offer PCB layout advantages in space-constrained designs.

For Upgraded Performance: The C2220C684KARAC7800 (KEMET) and GRM55DR72E684KW01L (Murata Electronics) both offer 250V voltage ratings with ±10% tolerance, providing enhanced performance margins. Both parts maintain Active product status and ROHS3 compliance. The KEMET part features the smallest thickness (0.057"), while the Murata part offers intermediate thickness (0.087"). These upgrades are suitable for new designs or applications requiring improved reliability and voltage headroom.

For Tolerance Improvement: The C5750X7R2A684K160KA and C5750X7R2A684K160KM from TDK Corporation provide ±10% tolerance at the original 100V rating, improving capacitance accuracy without voltage upgrade. Both parts carry "Not For New Designs" status but remain available in substantial inventory quantities.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and the required operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can I use a 250V rated capacitor in place of a 100V rated capacitor? A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible. The 250V parts (C2220C684KARAC7800 and GRM55DR72E684KW01L) function correctly in circuits designed for 100V operation.

Q: What is the difference between ±20% and ±10% tolerance? A: Tolerance specifies the allowable deviation from the nominal 0.68 µF value. ±20% allows deviation from 0.544 µF to 0.816 µF, while ±10% restricts deviation to 0.612 µF to 0.748 µF. Tighter tolerance (±10%) provides more precise capacitance values for applications requiring strict performance specifications.

Q: Why do some parts show "Not For New Designs" status? A: This designation indicates the manufacturer has discontinued the part for new applications, though existing inventory remains available. These parts are suitable for maintenance, repair, and legacy system support but should not be selected for new product development.

Q: Are all substitute parts in the same 2220 package? A: Yes. All listed parts use the 2220 (5750 Metric) package format with identical footprint dimensions of 0.224" L × 0.197" W. Thickness varies between 0.057" and 0.090", which may affect PCB stack-up considerations but does not impact electrical compatibility.

Q: Which substitute offers the best availability? A: The C5750X7R2A684M160KA (TDK) shows the highest inventory at 2811 pieces, followed by C5750X7R2A684K160KM (TDK) at 2420 pieces. Both are available in Tape & Reel packaging.

Q: Are all parts ROHS3 compliant? A: Yes. All listed parts, including the main part and all substitutes, are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.
