Substitute Part Grouping Explanation

Substitution of ceramic capacitors in the 0201 package form factor is determined by strict equivalence across electrical and mechanical parameters. The MMASU063SCG9R5DFNA01 and its identified substitute UMK063CG9R5DTHF share identical specifications in the following critical parameters:

Capacitance value of 9.5 pF with ±0.5pF tolerance ensures functional equivalence in circuit applications. Voltage rating of 50V is identical across both parts. Temperature coefficient classification as C0G/NP0 provides matching frequency stability and temperature performance characteristics. Operating temperature range of -55°C to 125°C is consistent. Package designation of 0201 (0603 Metric) ensures mechanical and footprint compatibility. Physical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum thickness of 0.013" (0.33mm) are identical. Surface mount MLCC mounting type is consistent. RoHS3 compliance and MSL 1 rating are matched across both parts.

The substitute part differs in product series designation (M series versus MMAS series), product status (Not For New Designs versus Active), and application focus (Automotive with AEC-Q200 certification versus Medical/Non-Critical). These differences do not affect electrical or mechanical substitutability but reflect manufacturing lineage and qualification status.

Parameter Comparison

Engineering Selection Recommendations

The MMASU063SCG9R5DFNA01 is the primary selection for new designs due to its Active product status and current availability of 938 pieces in inventory. This part is suitable for medical and non-critical applications requiring ROHS3 compliance and unlimited moisture sensitivity handling.

The UMK063CG9R5DTHF serves as a direct electrical and mechanical substitute when the primary part is unavailable or when automotive-grade qualification is required. This part carries AEC-Q200 certification, indicating qualification for automotive applications. However, its Not For New Designs status indicates that Taiyo Yuden has transitioned this product line. The UMK063CG9R5DTHF remains available with 2150 pieces in inventory and is suitable for legacy design support, field replacements, or applications requiring automotive-grade components.

Both parts are manufactured by Taiyo Yuden and share identical electrical performance, mechanical dimensions, and environmental compliance ratings. Selection between these parts depends on application requirements (medical versus automotive), design phase (new versus legacy), and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the UMK063CG9R5DTHF be used as a direct replacement for the MMASU063SCG9R5DFNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance value of 9.5 pF, tolerance of ±0.5pF, voltage rating of 50V, temperature coefficient of C0G/NP0, operating temperature range of -55°C to 125°C, and 0201 (0603 Metric) package dimensions. Substitution is valid from an engineering standpoint.

Q: What is the significance of the "Not For New Designs" status on the UMK063CG9R5DTHF?

A: This designation indicates that Taiyo Yuden has discontinued active development and promotion of this product series. New designs should utilize the MMASU063SCG9R5DFNA01 (Active status). The UMK063CG9R5DTHF remains available for legacy system support and field replacements but is not recommended for new product development.

Q: Are there differences in reliability or performance between these two parts?

A: No differences in electrical performance or reliability are indicated by the provided specifications. Both parts are ROHS3 compliant, carry MSL 1 rating (Unlimited moisture sensitivity), and operate across the identical temperature range. The UMK063CG9R5DTHF carries AEC-Q200 automotive qualification, which represents additional testing and validation for automotive environments.

Q: Can these parts be used interchangeably on the same printed circuit board assembly?

A: Yes. Both parts use identical 0201 (0603 Metric) package dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum thickness of 0.013" (0.33mm). They are both surface mount MLCCs with identical footprints and can be used interchangeably on the same PCB assembly without layout or design modifications.

Q: What applications are these capacitors suitable for?

A: The MMASU063SCG9R5DFNA01 is specified for medical and non-critical applications. The UMK063CG9R5DTHF is specified for automotive applications and carries AEC-Q200 certification. Both parts are suitable for general-purpose RF, timing, and coupling applications requiring stable C0G/NP0 temperature characteristics and low capacitance values.

Q: How do I determine which part to order for my application?

A: For new designs, order the MMASU063SCG9R5DFNA01 (Active status). For legacy system support or when automotive-grade qualification is required, the UMK063CG9R5DTHF is available. Both parts are manufactured by Taiyo Yuden and are electrically and mechanically equivalent. Verify application requirements and compliance certifications before final selection.
