MBASU063SCG4R2CFNA01 Equivalent & Substitute Parts

Part Overview

The MBASU063SCG4R2CFNA01 is a 4.2 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 50V operation with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is packaged in 0201 (0603 Metric) form factor and is designated for general purpose applications. The part maintains Active product status with 673 units currently in stock. Substitute parts become necessary when inventory constraints occur, when design requirements shift toward automotive-qualified components, or when alternative sourcing from the same manufacturer is preferred while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBASU063SCG4R2CFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (4.2 pF), tolerance (±0.25pF), rated voltage (50V), and temperature coefficient (C0G/NP0) must remain identical. These parameters define the functional behavior of the capacitor in circuit operation.

Mechanical Parameters: Package type (0201/0603 Metric), mounting method (Surface Mount, MLCC), physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm), and maximum thickness (0.013"/0.33mm) must match to ensure compatibility with printed circuit board layouts and assembly processes.

Compliance Parameters: RoHS3 compliance and MSL rating (1 - Unlimited) must be maintained to satisfy regulatory and manufacturing requirements.

The substitute part UMK063CG4R2CTHF from Taiyo Yuden meets all these criteria while introducing automotive-grade qualification (AEC-Q200) and a "Not For New Designs" status designation.

Parameter Comparison

Engineering Selection Recommendations

MBASU063SCG4R2CFNA01 Selection Criteria: Select this part for general purpose applications requiring a 4.2 pF ceramic capacitor with standard industrial compliance. The Active product status indicates ongoing manufacturer support and availability. This part is appropriate for new design implementations where automotive qualification is not a requirement.

UMK063CG4R2CTHF Selection Criteria: Select this part when automotive-grade qualification (AEC-Q200) is mandated by application requirements or when design specifications explicitly require automotive-rated components. The "Not For New Designs" status indicates this part is maintained for legacy system support and existing design continuity. This part is electrically and mechanically equivalent to the MBASU063SCG4R2CFNA01 and provides automotive reliability assurance through AEC-Q200 certification.

Substitution Guidance: Both parts are manufactured by Taiyo Yuden and share identical electrical and mechanical specifications. The primary differentiation lies in product lifecycle status and application qualification. Substitution between these parts is valid when the design context permits transition between general purpose and automotive-qualified components.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG4R2CTHF be used as a direct replacement for MBASU063SCG4R2CFNA01?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (4.2 pF), tolerance (±0.25pF), voltage rating (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (0201/0603 Metric), and physical dimensions. The UMK063CG4R2CTHF includes AEC-Q200 automotive qualification, which does not prevent its use in general purpose applications.

Q: What is the significance of the "Not For New Designs" status on UMK063CG4R2CTHF?

A: This designation indicates the part is maintained by the manufacturer for existing design support and legacy system continuity, but is not recommended for incorporation into newly developed products. For new designs, the MBASU063SCG4R2CFNA01 (Active status) is the preferred selection. However, the part remains fully functional and available for existing applications.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use identical 0201 (0603 Metric) surface mount packaging with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). They are interchangeable at the PCB assembly level.

Q: What does AEC-Q200 certification mean for the UMK063CG4R2CTHF?

A: AEC-Q200 is an automotive industry standard qualification that certifies the component meets reliability and performance requirements for automotive applications. This certification does not restrict use in non-automotive applications; it indicates the part has undergone additional testing and validation beyond standard industrial requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MBASU063SCG4R2CFNA01 and UMK063CG4R2CTHF are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating they meet environmental and moisture sensitivity requirements for industrial and automotive applications.

Q: What inventory considerations should be evaluated?

A: MBASU063SCG4R2CFNA01 has 673 units in stock, while UMK063CG4R2CTHF has 887 units in stock. Both parts are available in Tape & Reel (TR) packaging. Inventory selection should be based on application requirements and product lifecycle strategy rather than stock quantity alone.
