MBASU063SCG3R4CFNA01 Equivalent & Substitute Parts

Part Overview

The MBASU063SCG3R4CFNA01 is a 3.4 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 and is currently available in inventory. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate components with different application certifications or product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBASU063SCG3R4CFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 3.4 pF
• Tolerance: ±0.25pF
• Voltage rating: 50V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 0201 (0603 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Maximum thickness: 0.013" (0.33mm)

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute part UMK063CG3R4CTHF matches all electrical, mechanical, and compliance parameters. Substitution is valid when these parameters align across both components. Differences in product status, application classification, or series designation do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The MBASU063SCG3R4CFNA01 is the recommended selection for new designs. This part maintains Active product status, ensuring long-term availability and manufacturer support. It is suitable for general purpose applications and carries ROHS3 compliance certification.

Substitute Part Selection: The UMK063CG3R4CTHF is functionally equivalent across all critical electrical, mechanical, and compliance parameters. However, this part is designated "Not For New Designs" and carries AEC-Q200 automotive qualification. Selection of this substitute is appropriate only when:

• The primary part is unavailable through normal supply channels
• Existing inventory of the substitute part is available for immediate use
• The application does not require long-term manufacturer support or design continuity
• Automotive-grade qualification is not a requirement for the application

Both parts are manufactured by Taiyo Yuden and share identical electrical specifications, package dimensions, and RoHS3 compliance status. The decision between these parts should be based on product lifecycle requirements and supply chain considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG3R4CTHF be used as a direct replacement for MBASU063SCG3R4CFNA01?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (3.4 pF), tolerance (±0.25pF), voltage rating (50V), temperature coefficient (C0G/NP0), package type (0201), and physical dimensions. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between these two parts?

A: The primary differences are product status and application classification. MBASU063SCG3R4CFNA01 is Active and designated for general purpose use. UMK063CG3R4CTHF is marked "Not For New Designs" and carries AEC-Q200 automotive qualification. These differences do not affect electrical or mechanical performance.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 0201 (0603 Metric) package 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 pin-compatible and footprint-compatible.

Q: Can I use the automotive-qualified part in a general purpose application?

A: Yes. The UMK063CG3R4CTHF meets or exceeds the specifications required for general purpose applications. Automotive qualification does not restrict use in non-automotive applications.

Q: What does "Not For New Designs" mean for the substitute part?

A: This designation indicates that the manufacturer is not recommending this part for new product designs. It may be retained for legacy or existing production support. For new designs, the Active part MBASU063SCG3R4CFNA01 is the appropriate selection.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

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

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
