Substitute Part Grouping Explanation

Substitution of the MBASU063SCG4R3CFNA01 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain constant for a part to function as a direct substitute:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 4.3 pF
• Tolerance: ±0.25 pF
• Voltage rating: 50V
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C to 125°C

Mechanical Parameters (Non-Negotiable):

• 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 required
• MSL 1 rating required

Substitute parts identified in this reference meet all specified parameters. Differences in manufacturer, series designation, product status, or application focus (general purpose versus automotive) do not affect functional equivalence when all electrical and mechanical parameters are identical.

Engineering Selection Recommendations

Primary Selection: MBASU063SCG4R3CFNA01

The MBASU063SCG4R3CFNA01 is the recommended primary choice for new designs. This part maintains active product status, ensuring long-term availability and supply chain stability. It is RoHS3 compliant with MSL 1 rating and is suitable for general purpose applications.

Alternative Selection: CC0201CRNPO9BN4R3 (YAGEO)

The CC0201CRNPO9BN4R3 provides parametric equivalence with identical electrical and mechanical specifications. This part is manufactured by YAGEO and maintains active product status. Selection of this alternative is appropriate when YAGEO sourcing is preferred or when supply constraints on Taiyo Yuden parts necessitate alternative manufacturer sourcing. The part is RoHS3 compliant with MSL 1 rating and supports general purpose applications.

Conditional Selection: UMK063CG4R3CTHF (Taiyo Yuden)

The UMK063CG4R3CTHF is electrically and mechanically equivalent to the primary part. However, this part carries "Not For New Designs" product status and is qualified to AEC-Q200 automotive standards. Selection of this part is limited to applications requiring automotive qualification or to existing designs where this part number is already established. For new designs, the primary part (MBASU063SCG4R3CFNA01) or the YAGEO alternative (CC0201CRNPO9BN4R3) are preferred.

Frequently Asked Questions (FAQ)

Q: Can the UMK063CG4R3CTHF be used in new designs?

A: The UMK063CG4R3CTHF carries "Not For New Designs" product status. For new designs, use MBASU063SCG4R3CFNA01 or CC0201CRNPO9BN4R3. The UMK063CG4R3CTHF is appropriate only for existing designs or applications requiring AEC-Q200 automotive qualification.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical package specifications (0201/0603 Metric), dimensions (0.024" L x 0.012" W), and maximum thickness (0.013"). They are physically interchangeable on PCB layouts designed for the 0201 package format.

Q: What is the difference between C0G and NPO designations?

A: C0G and NPO are equivalent temperature coefficient designations used by different manufacturers. Both indicate zero temperature coefficient performance across the operating range. Taiyo Yuden uses C0G/NP0 notation, while YAGEO uses C0G/NPO notation. The electrical performance is identical.

Q: Why would I select the YAGEO part over the Taiyo Yuden primary part?

A: The CC0201CRNPO9BN4R3 (YAGEO) provides an alternative manufacturer source with identical electrical and mechanical specifications. Selection is appropriate for supply chain diversification, cost optimization, or when Taiyo Yuden parts are unavailable. Both the primary part and YAGEO alternative maintain active product status.

Q: Are there any compliance differences between the three parts?

A: All three parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The UMK063CG4R3CTHF carries additional AEC-Q200 automotive qualification. For general purpose applications, all three parts meet identical compliance requirements.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required prior to assembly.

Q: Can these parts be used interchangeably in existing production?

A: Yes, provided the design does not specify a particular manufacturer part number. All three parts meet identical electrical and mechanical parameters. However, design documentation and bill of materials should be updated to reflect any part number changes for traceability and future procurement.
