Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMASU063SCG8R2DFNA01 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance value: 8.2 pF
• Tolerance: ±0.5pF
• Voltage rating: 50V (equal or higher)
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 125°C
• Package format: 0201 (0603 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Thickness: 0.013" (0.33mm) maximum
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The substitute part UMK063CG8R2DTHF meets all critical electrical and mechanical parameters required for direct substitution. Both parts are manufactured by Taiyo Yuden and share identical capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The MMASU063SCG8R2DFNA01 is the recommended selection for new designs. This part maintains Active product status, ensuring long-term availability and manufacturer support. It is specifically qualified for medical and non-critical applications.

Substitute Part Selection: The UMK063CG8R2DTHF is electrically and mechanically equivalent to the MMASU063SCG8R2DFNA01 and is suitable for direct substitution when the primary part is unavailable. However, this substitute carries a "Not For New Designs" product status designation, indicating it is intended for legacy or existing design support only.

The UMK063CG8R2DTHF includes AEC-Q200 automotive qualification, which provides additional reliability assurance through automotive-grade testing and screening protocols. This certification does not restrict its use in non-automotive applications but indicates enhanced quality assurance.

Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can the UMK063CG8R2DTHF be used as a direct replacement for the MMASU063SCG8R2DFNA01?

A: Yes. Both parts are electrically and mechanically identical with respect to capacitance (8.2 pF), tolerance (±0.5pF), voltage rating (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package format (0201/0603 Metric), and physical dimensions. They are pin-compatible and footprint-compatible for PCB assembly.

Q: What is the significance of the "Not For New Designs" status on the UMK063CG8R2DTHF?

A: This designation indicates the substitute part is in mature or declining production phase and is intended for sustaining existing designs rather than new product development. For new designs, the MMASU063SCG8R2DFNA01 (Active status) is the appropriate selection.

Q: Are there any compliance or certification differences between these parts?

A: The UMK063CG8R2DTHF includes AEC-Q200 automotive qualification, while the MMASU063SCG8R2DFNA01 does not specify this certification. Both parts are ROHS3 compliant and carry MSL 1 moisture sensitivity rating. The AEC-Q200 certification on the substitute part indicates automotive-grade reliability testing and does not restrict its use in other applications.

Q: Do these parts have identical physical dimensions and mounting characteristics?

A: Yes. Both parts are packaged in 0201 (0603 Metric) surface mount format with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). They are compatible with standard 0201 PCB footprints and reflow soldering processes.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating they do not require special moisture control during storage, handling, or assembly. Standard manufacturing and storage conditions are acceptable.

Q: Can these parts be used interchangeably in medical applications?

A: The MMASU063SCG8R2DFNA01 is specified for medical and non-critical applications. The UMK063CG8R2DTHF is specified for automotive applications. While both parts meet identical electrical and mechanical specifications, application-specific qualification requirements should be evaluated based on the end-use medical device classification and regulatory requirements.
