MMASU063SCG4R2CFNA01 Equivalent & Substitute Parts

Part Overview

The MMASU063SCG4R2CFNA01 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 designed for medical and non-critical applications. The part maintains an Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements shift toward alternative qualification standards such as automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMASU063SCG4R2CFNA01 is determined by strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Capacitance value: 4.2 pF
• Tolerance specification: ±0.25pF
• Voltage rating: 50V minimum
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 125°C
• Package form factor: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Mounting type: Surface Mount, MLCC

The substitute part UMK063CG4R2CTHF meets all critical electrical and mechanical parameters. Both parts are manufactured by Taiyo Yuden, share identical capacitance, tolerance, voltage rating, temperature coefficient, and physical dimensions. The primary distinction lies in product status and application qualification: the main part targets medical and non-critical applications with Active status, while the substitute carries automotive-grade AEC-Q200 certification with Not For New Designs status.

Parameter Comparison

Engineering Selection Recommendations

MMASU063SCG4R2CFNA01 Selection Criteria: Select this part for new designs targeting medical and non-critical applications. The Active product status ensures long-term availability and manufacturer support. This part is the primary choice for applications without automotive qualification requirements.

UMK063CG4R2CTHF Selection Criteria: This substitute part is electrically and mechanically equivalent and carries AEC-Q200 automotive qualification. However, its Not For New Designs status indicates this part is in end-of-life phase. Selection of this substitute is appropriate only when the main part is unavailable and existing inventory of the substitute is accessible. The automotive-grade certification does not restrict use in non-automotive applications; it indicates additional qualification testing has been performed.

Both parts maintain identical electrical performance, physical dimensions, and environmental compliance. Selection between them depends on application context and supply availability rather than technical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG4R2CTHF be used as a direct replacement for MMASU063SCG4R2CFNA01?

A: Yes. Both parts share identical capacitance (4.2 pF), tolerance (±0.25pF), voltage rating (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and physical dimensions (0201 / 0603 Metric). Electrical and mechanical compatibility is complete.

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

A: This designation indicates the UMK063CG4R2CTHF is in end-of-life phase and the manufacturer does not recommend its use in new product designs. Existing inventory may be available for legacy system support or replacement applications, but long-term supply cannot be guaranteed.

Q: Does the AEC-Q200 certification on the substitute part affect its use in non-automotive applications?

A: No. AEC-Q200 certification represents additional qualification testing performed by the manufacturer. This certification does not restrict the part's use in non-automotive applications; it indicates the part meets automotive industry reliability standards and can be used in any application requiring equivalent or lower performance specifications.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts are packaged in 0201 (0603 Metric) form factor with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). PCB footprint and assembly compatibility are identical.

Q: What is the moisture sensitivity rating for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both MMASU063SCG4R2CFNA01 and UMK063CG4R2CTHF are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.
