MMASU063SCG040CFNA01 Equivalent & Substitute Parts

Part Overview

The MMASU063SCG040CFNA01 is a 4 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 50V with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 0201 package format is designed for applications requiring stable capacitance across temperature variations. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and component availability options for applications where the primary part may be unavailable or where specific manufacturer certifications are required.

Frequently Asked Questions (FAQ)

Q: Can CGA1A2C0G1H040C030BA replace MMASU063SCG040CFNA01 in non-automotive applications?

A: Yes. CGA1A2C0G1H040C030BA meets all electrical and mechanical specifications of MMASU063SCG040CFNA01. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive applications. Direct substitution is possible without circuit modifications.

Q: What is the difference between the three substitute parts?

A: All three parts are electrically and mechanically identical with 4 pF capacitance, 50V rating, C0G/NP0 temperature coefficient, and 0201 package format. The primary differences are manufacturer identity and certifications: TDK CGA1A2C0G1H040C030BA includes AEC-Q200 automotive qualification; YAGEO CC0201CRNPO9BN4R0 is general-purpose with highest inventory; Taiyo Yuden MMASU063SCG040CFNA01 is specified for medical and non-critical applications.

Q: Are there any physical compatibility issues when substituting these parts?

A: No. All three parts share identical package format (0201/0603 Metric), dimensions (0.024" L x 0.012" W), and thickness (0.013" maximum). PCB footprints, reflow profiles, and assembly processes are identical. Direct board-level substitution is possible without design changes.

Q: Which part should be selected for highest supply availability?

A: CC0201CRNPO9BN4R0 (YAGEO) provides the highest inventory at 30,769 pieces. This part is recommended for applications where supply chain continuity and immediate availability are critical factors.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture-related storage or handling restrictions. Standard storage conditions apply to all three parts.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the application does not have specific manufacturer requirements or certifications. All three parts meet ROHS3 compliance and carry identical electrical specifications. Production changeover between these parts requires no circuit or assembly process modifications.
