2220PC684MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 2220PC684MAT1A is a 0.68 µF ceramic capacitor manufactured by KYOCERA AVX, rated for 250V with X7R temperature coefficient characteristics. 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 with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2220PC684MAT1A is determined by the following mandatory parameters:

• Capacitance value: 0.68 µF (exact match required)
• Voltage rating: 250V (exact match required)
• Temperature coefficient: X7R (exact match required)
• Package format: 2220 (5750 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The identified substitute parts meet all mandatory electrical and mechanical parameters. Variations in tolerance and physical thickness do not affect functional substitution within the specified application constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2220PC684MAT1A (KYOCERA AVX), C2220C684KARAC7800 (KEMET), and GRM55DR72E684KW01L (Murata Electronics)—are active production parts with ROHS3 compliance and MSL 1 rating. Selection between these parts may be based on:

• Tolerance requirements: The KEMET and Murata parts offer ±10% tolerance compared to ±20% for the KYOCERA AVX part, providing tighter capacitance control where required.
• Physical thickness constraints: The KEMET part (1.45mm max) is thinner, while the Murata part (2.20mm max) is thicker than the original KYOCERA AVX part (2.00mm max). PCB layout and component stacking considerations should guide selection.
• Inventory availability and lead time from respective manufacturers.

All parts maintain identical electrical performance across the specified operating temperature range and voltage rating.

Frequently Asked Questions (FAQ)

Q: Can C2220C684KARAC7800 directly replace 2220PC684MAT1A in my circuit?

A: Yes. Both parts share identical capacitance (0.68 µF), voltage rating (250V), temperature coefficient (X7R), package format (2220), and operating temperature range (-55°C ~ 125°C). The KEMET part features tighter tolerance (±10% vs ±20%), which may improve circuit performance. Physical thickness differs (1.45mm vs 2.00mm), which is acceptable for most PCB layouts.

Q: What is the difference between the substitute parts?

A: The primary differences are tolerance specification and maximum thickness. C2220C684KARAC7800 (KEMET) offers ±10% tolerance and 1.45mm thickness. GRM55DR72E684KW01L (Murata) offers ±10% tolerance and 2.20mm thickness. All other electrical and mechanical parameters are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three parts—2220PC684MAT1A, C2220C684KARAC7800, and GRM55DR72E684KW01L—are ROHS3 compliant with MSL 1 moisture sensitivity rating.

Q: Does package thickness affect PCB assembly?

A: Package thickness may impact PCB layout if component stacking or height constraints exist. The KEMET part (1.45mm) is thinner, the KYOCERA AVX part (2.00mm) is standard, and the Murata part (2.20mm) is thicker. Verify PCB design clearances before selection.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your circuit design accommodates the tolerance and thickness variations. All parts meet the same electrical specifications and compliance requirements for general purpose applications.
