MMASU063SCG090DFNA01 Equivalent & Substitute Parts

Part Overview

The MMASU063SCG090DFNA01 is a 9 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 50V with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is packaged in 0201 (0603 Metric) form factor and is designed for applications requiring stable capacitance across temperature ranges from -55°C to 125°C. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating. 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 design requirements permit functional interchange.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMASU063SCG090DFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (9 pF), tolerance (±0.5pF), and rated voltage (50V) must be identical. Temperature coefficient designation (C0G/NP0) ensures predictable capacitance stability across the operating temperature range of -55°C to 125°C.

Mechanical Parameters: Package type (0201 / 0603 Metric), mounting method (Surface Mount, MLCC), and physical dimensions (0.024" L x 0.012" W, 0.013" max thickness) must match to ensure compatibility with printed circuit board layouts and assembly processes.

Compliance Parameters: RoHS3 compliance and MSL 1 rating are maintained across all substitute parts to ensure environmental and moisture handling requirements are met.

Substitute parts identified within this grouping share identical electrical and mechanical specifications, enabling direct functional interchange without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Both the MMASU063SCG090DFNA01 (Taiyo Yuden) and CGA1A2C0G1H090D030BA (TDK Corporation) are Active status products with full RoHS3 compliance and MSL 1 ratings. Selection between these parts is based on supply chain availability, inventory levels, and application-specific requirements.

The TDK Corporation CGA1A2C0G1H090D030BA carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring formal qualification documentation. The Taiyo Yuden MMASU063SCG090DFNA01 is specified for medical and non-critical applications.

Both parts are electrically and mechanically equivalent, with identical capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications. Selection should be driven by application classification, supply availability, and procurement requirements rather than technical performance differences.
