Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMASU063SCG4R9CFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 4.9 pF
• Tolerance: ±0.25pF
• Voltage rating: 50V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 0201 (0603 Metric)
• Mounting configuration: 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
• Moisture sensitivity level: 1 (Unlimited)

The substitute part UMK063CG4R9CTHF maintains complete alignment with all electrical, mechanical, and compliance specifications. Substitution is valid when these parameters remain unchanged across the component selection.

Engineering Selection Recommendations

MMASU063SCG4R9CFNA01 (Primary Selection)

Select this part for new designs and applications requiring long-term component availability. The Active product status ensures continued manufacturing support and supply chain stability. This part is suitable for medical and non-critical applications where standard reliability requirements apply.

UMK063CG4R9CTHF (Substitute Selection)

This part is electrically and mechanically equivalent to the MMASU063SCG4R9CFNA01 and carries AEC-Q200 automotive qualification. However, the Not For New Designs status indicates this part is in end-of-life phase. Selection of UMK063CG4R9CTHF is appropriate only for existing designs requiring component replacement or for applications where automotive-grade qualification is a specific requirement and design phase constraints permit use of legacy components. New design implementations should prioritize the MMASU063SCG4R9CFNA01 to ensure long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG4R9CTHF be used as a direct replacement for MMASU063SCG4R9CFNA01 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 4.9 pF capacitance, ±0.25pF tolerance, 50V rating, C0G/NP0 temperature coefficient, 0201 package, and identical physical dimensions. Direct substitution is valid from a component compatibility standpoint.

Q: What is the significance of the "Not For New Designs" status on UMK063CG4R9CTHF?

A: This designation indicates the part is in end-of-life phase and is not recommended for incorporation into new product designs. While the part remains functionally equivalent, future availability cannot be guaranteed. New designs should utilize MMASU063SCG4R9CFNA01, which maintains Active status.

Q: Are there application differences between these parts?

A: The MMASU063SCG4R9CFNA01 is designated for medical and non-critical applications. The UMK063CG4R9CTHF carries AEC-Q200 automotive qualification. Both parts meet the same electrical and mechanical specifications; the difference lies in qualification pathway and intended application domain.

Q: Does the 0201 package size present any assembly considerations?

A: The 0201 (0603 Metric) package is a miniature surface mount form factor measuring 0.024" L x 0.012" W (0.60mm x 0.30mm). Assembly equipment must support this package size. Both substitute parts are identical in package dimensions, so no assembly process changes are required when switching between them.

Q: Are both parts RoHS compliant?

A: Yes. Both MMASU063SCG4R9CFNA01 and UMK063CG4R9CTHF are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
