Substitute Part Grouping Explanation

Substitution of ceramic capacitors is determined by strict equivalence across electrical and mechanical parameters. The MBASU063SCG8R4DFNA01 can be substituted with the UMK063CG8R4DTHF based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Capacitance value: 8.4 pF
• Tolerance: ±0.5pF
• Voltage rating: 50V
• Temperature coefficient: C0G, NP0
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 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 Compliant status
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part UMK063CG8R4DTHF meets all electrical and mechanical requirements for direct substitution. Differences in product status and application classification do not affect functional equivalence in circuits designed for the primary part.

Engineering Selection Recommendations

Primary Part Selection: The MBASU063SCG8R4DFNA01 is the recommended selection for new designs. This part maintains Active product status from Taiyo Yuden, ensuring continued availability and manufacturing support. The part is suitable for general purpose applications and carries full RoHS3 compliance with MSL 1 rating.

Substitute Part Selection: The UMK063CG8R4DTHF is electrically and mechanically equivalent to the primary part and can be used as a direct substitute when the primary part is unavailable. This part carries AEC-Q200 automotive qualification, indicating it meets automotive industry reliability standards. However, the substitute part is designated as "Not For New Designs," indicating that Taiyo Yuden does not recommend its use in new product development. The substitute part is suitable for replacement, repair, or legacy system applications where the primary part cannot be sourced.

Compliance Considerations: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly. Both parts are manufactured by the same supplier, ensuring consistent quality and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the UMK063CG8R4DTHF be used as a direct replacement for the MBASU063SCG8R4DFNA01 in existing designs?

A: Yes. The UMK063CG8R4DTHF is electrically and mechanically equivalent to the MBASU063SCG8R4DFNA01. All critical parameters including capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications are identical. The substitute part can be used in existing designs without circuit modification.

Q: Why is the UMK063CG8R4DTHF marked as "Not For New Designs"?

A: The "Not For New Designs" designation indicates that Taiyo Yuden has transitioned this part to end-of-life status and recommends using the MBASU063SCG8R4DFNA01 for new product development.
