MBASU063SCG6R4DFNA01 Equivalent & Substitute Parts

Part Overview

The MBASU063SCG6R4DFNA01 is a 6.4 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 general purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C.

The part is currently in Active product status. Substitute parts become necessary when inventory availability changes, when design requirements shift toward automotive-qualified components, or when transitioning to alternative product lines within the same manufacturer's portfolio.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBASU063SCG6R4DFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 6.4 pF
• Tolerance: ±0.5pF
• Voltage rating: 50V minimum
• Temperature coefficient: C0G/NP0

Physical Parameters (Non-Negotiable):

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

Compliance Parameters:

• RoHS3 compliance required
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part UMK063CG6R4DTHF meets all electrical, physical, and compliance requirements. The primary distinction is product status and application focus: the substitute carries AEC-Q200 automotive qualification and is designated for automotive and SMPS filtering applications, whereas the main part is positioned for general purpose use.

Parameter Comparison

Engineering Selection Recommendations

For Active Production (Recommended): The MBASU063SCG6R4DFNA01 is the appropriate selection for new designs and active production. This part maintains Active product status, ensuring long-term availability and manufacturer support. It satisfies all electrical and mechanical requirements for general purpose applications while maintaining full ROHS3 compliance.

For Automotive or Filtered Power Supply Applications: The UMK063CG6R4DTHF substitute is electrically and mechanically identical to the main part and carries AEC-Q200 automotive qualification. However, this part is designated "Not For New Designs," indicating the manufacturer is transitioning away from this product line. Selection of this substitute should be limited to legacy design support or applications where existing inventory must be utilized.

Compliance Considerations: Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements beyond standard ESD precautions. Both are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG6R4DTHF be used as a direct replacement for MBASU063SCG6R4DFNA01?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 6.4 pF capacitance, ±0.5pF tolerance, 50V rating, C0G/NP0 temperature coefficient, 0201 package format, and identical physical dimensions. The substitute will function identically in the circuit.

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

A: This designation indicates the manufacturer is discontinuing the UMK063CG6R4DTHF product line. New designs should use the MBASU063SCG6R4DFNA01, which carries Active status and ensures continued availability and manufacturer support throughout the product lifecycle.

Q: Are there any differences in handling or storage between these two parts?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), meaning neither requires special moisture control during storage or handling. Standard ESD precautions apply to both.

Q: Why does the substitute part have AEC-Q200 qualification while the main part does not?

A: The UMK063CG6R4DTHF is positioned for automotive applications and carries AEC-Q200 automotive qualification. The MBASU063SCG6R4DFNA01 is positioned for general purpose applications and does not require this automotive qualification. Both parts meet identical electrical and mechanical specifications.

Q: Can the substitute be used in automotive applications if the main part is specified?

A: The substitute carries AEC-Q200 automotive qualification, making it suitable for automotive applications. However, since the main part is designated for general purpose use and the substitute is "Not For New Designs," the main part should be specified for new designs regardless of application type.

Q: Are the physical footprints identical for PCB layout purposes?

A: Yes. Both parts use the 0201 (0603 Metric) package with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). PCB layouts are fully interchangeable.
