MBASU063SCG8R5DFNA01 Equivalent & Substitute Parts

Part Overview

The MBASU063SCG8R5DFNA01 is an 8.5 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 50V operation with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is packaged in 0201 (0603 Metric) form factor and is currently in Active product status. Identifying equivalent and substitute parts becomes necessary when addressing inventory constraints, supply chain disruptions, or design phase transitions where alternative qualified components may be required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBASU063SCG8R5DFNA01 ceramic capacitor is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (8.5 pF), tolerance (±0.5pF), rated voltage (50V), and temperature coefficient (C0G/NP0) must remain identical. These parameters directly affect circuit performance and frequency stability.

Mechanical Parameters: Package type (0201/0603 Metric), physical dimensions (0.024" L x 0.012" W, 0.013" max thickness), and mounting type (Surface Mount, MLCC) must be maintained for PCB layout and assembly compatibility.

Environmental & Compliance Parameters: Operating temperature range (-55°C ~ 125°C), RoHS3 compliance, and MSL rating (1 - Unlimited) establish the environmental operating envelope and regulatory qualification baseline.

Substitute parts must satisfy all these parameters without deviation to ensure functional and mechanical interchangeability.

Engineering Selection Recommendations

Primary Selection: MBASU063SCG8R5DFNA01

The MBASU063SCG8R5DFNA01 is the recommended choice for new designs. This part maintains Active product status, ensuring long-term availability and manufacturer support. It is qualified for general-purpose applications and carries full ROHS3 compliance with unlimited moisture sensitivity rating.

Substitute Selection: UMK063CG8R5DTHF

The UMK063CG8R5DTHF is electrically and mechanically equivalent to the primary part. However, this component carries a "Not For New Designs" product status designation. The UMK063CG8R5DTHF is qualified to AEC-Q200 automotive standards and is suitable for automotive applications where such qualification is required. This part should be selected only when automotive-grade certification is a design requirement or when the primary part is unavailable and backward compatibility with existing inventory is necessary.

Both parts are manufactured by Taiyo Yuden and share identical electrical specifications, package dimensions, and environmental ratings. Selection between them depends on application requirements and product lifecycle considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the UMK063CG8R5DTHF be used as a direct replacement for the MBASU063SCG8R5DFNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical in all critical parameters: 8.5 pF capacitance, ±0.5pF tolerance, 50V rating, C0G/NP0 temperature coefficient, 0201 package, and operating temperature range of -55°C to 125°C. Direct substitution is permissible from a technical standpoint.

Q: What is the significance of the "Not For New Designs" status on the UMK063CG8R5DTHF?

A: This designation indicates that the manufacturer is not recommending this part for new product development. While the part remains functionally equivalent and available, designs should prioritize the MBASU063SCG8R5DFNA01 (Active status) for long-term supply chain stability and manufacturer support continuity.

Q: Why does the UMK063CG8R5DTHF have AEC-Q200 qualification while the MBASU063SCG8R5DFNA01 does not?

A: The UMK063CG8R5DTHF is specifically qualified for automotive applications under AEC-Q200 standards. The MBASU063SCG8R5DFNA01 is designated for general-purpose applications. If automotive-grade certification is required by design specifications, the UMK063CG8R5DTHF must be selected.

Q: Are there any dimensional or packaging differences between these parts?

A: No. Both parts are identical in package type (0201/0603 Metric), physical dimensions (0.024" L x 0.012" W), maximum thickness (0.013"), and mounting type (Surface Mount, MLCC). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the MBASU063SCG8R5DFNA01 and UMK063CG8R5DTHF are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and operate across the identical temperature range of -55°C to 125°C.

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

A: The MBASU063SCG8R5DFNA01 should be selected for new designs due to its Active product status, which ensures ongoing manufacturer support and supply availability. The UMK063CG8R5DTHF should be reserved for applications requiring automotive-grade AEC-Q200 qualification or for legacy design updates.
