Substitute Part Grouping Explanation

Substitution of the MMASU063SCG3R4CFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

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

Mechanical Equivalence Requirements:

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

Compliance Requirements:

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

The substitute part UMK063CG3R4CTHF meets all electrical and mechanical equivalence criteria. Both parts are manufactured by Taiyo Yuden and share identical capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications. The substitute part differs in product status (Not For New Designs) and application classification (Automotive with AEC-Q200 rating versus Medical/Non-Critical).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MMASU063SCG3R4CFNA01): The MMASU063SCG3R4CFNA01 is the recommended selection for new designs. This part maintains Active product status, ensuring long-term availability and manufacturer support. It is designated for medical and non-critical applications and carries full RoHS3 compliance with MSL 1 rating. The part is currently in stock with 980 units available.

Substitute Selection (UMK063CG3R4CTHF): The UMK063CG3R4CTHF provides electrical and mechanical equivalence and is suitable for applications where the automotive-grade AEC-Q200 certification is acceptable or beneficial. However, this part carries "Not For New Designs" status, indicating it is in the mature or end-of-life phase of its product lifecycle. Selection of this substitute should be limited to legacy design updates, repair applications, or situations where existing inventory must be utilized. The substitute part is currently in stock with 1692 units available.

Compliance Considerations: Both parts satisfy RoHS3 compliance requirements and maintain identical moisture sensitivity ratings. The substitute part's AEC-Q200 automotive qualification does not preclude its use in medical or non-critical applications; however, the primary part's Active status provides superior lifecycle assurance for new product development.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG3R4CTHF be used as a direct replacement for MMASU063SCG3R4CFNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (3.4 pF), tolerance (±0.25 pF), voltage rating (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), package type (0201/0603 Metric), physical dimensions, and compliance certifications (RoHS3, MSL 1). Direct substitution is supported from a technical standpoint.

Q: Why does the substitute part have "Not For New Designs" status?

A: "Not For New Designs" status indicates the part is in a mature or declining phase of its product lifecycle. Manufacturers assign this status when a part is being phased out or when production is being consolidated. For new product development, the Active-status MMASU063SCG3R4CFNA01 is the appropriate selection to ensure long-term availability and manufacturer support.

Q: Are there differences in application suitability between the two parts?

A: The MMASU063SCG3R4CFNA01 is classified for medical and non-critical applications, while the UMK063CG3R4CTHF is classified for automotive applications with AEC-Q200 certification. Both classifications indicate high reliability standards. The substitute part's automotive qualification does not restrict its use in medical or non-critical applications; however, the primary part's designation aligns with its intended application category.

Q: Do both parts have the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging in 0201 form factor (0603 metric). Physical dimensions are identical: 0.024" length × 0.012" width (0.60mm × 0.30mm) with maximum thickness of 0.013" (0.33mm). They are compatible with identical pick-and-place equipment and PCB assembly processes.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the part has unlimited shelf life and does not require special moisture-controlled storage or handling. Both the main part and substitute part carry this rating, eliminating moisture sensitivity as a differentiation factor. Standard storage conditions are sufficient for both components.

Q: Which part should be selected for a new medical device design?

A: The MMASU063SCG3R4CFNA01 is the appropriate selection for new medical device designs. It maintains Active product status, is explicitly designated for medical applications, and provides manufacturer lifecycle assurance. The substitute part's "Not For New Designs" status makes it unsuitable for new product development, regardless of its technical equivalence.
