MBASU063SCG4R4CFNA01 Equivalent & Substitute Parts

Part Overview

The MBASU063SCG4R4CFNA01 is a 4.4 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. Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit selection from alternative qualified sources while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the MBASU063SCG4R4CFNA01 is permissible with parts that maintain identical electrical and mechanical specifications across all critical parameters. The substitution logic is based on the following key parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 4.4 pF
• Tolerance: ±0.25pF
• Voltage rating: 50V (equal or higher)
• Temperature coefficient: C0G/NP0

Mechanical Parameters (Non-Negotiable):

• 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 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these criteria are classified as direct substitutes. Variations in manufacturer, series designation, or product status do not affect substitution eligibility when all electrical, mechanical, and compliance parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MBASU063SCG4R4CFNA01): The MBASU063SCG4R4CFNA01 is the recommended choice for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. It is suitable for general-purpose applications and maintains full compliance with ROHS3 environmental standards.

Substitute Selection (UMK063CG4R4CTHF): The UMK063CG4R4CTHF is electrically and mechanically equivalent to the primary part. However, this part is designated as "Not For New Designs," indicating that Taiyo Yuden does not recommend its use in new product development. The substitute carries AEC-Q200 automotive qualification, which is a superset of general-purpose requirements. This part is suitable for replacement, repair, or continuation of existing designs where the primary part is unavailable. Selection of this substitute should be limited to applications where design continuation or component replacement is the objective.

Compliance Consideration: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG4R4CTHF be used as a direct replacement for MBASU063SCG4R4CFNA01 in new designs?

A: No. While the UMK063CG4R4CTHF is electrically and mechanically equivalent, it carries "Not For New Designs" status. For new product development, the MBASU063SCG4R4CFNA01 (Active status) is the appropriate selection. The substitute is suitable for existing design continuation or component replacement only.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in 0201 (0603 Metric) form factor with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). PCB footprints and assembly processes are interchangeable.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive qualification standard. The UMK063CG4R4CTHF meets this automotive-grade specification, which exceeds general-purpose requirements. This qualification does not affect substitution eligibility for general-purpose applications but indicates the part has undergone additional reliability testing.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both the MBASU063SCG4R4CFNA01 and UMK063CG4R4CTHF carry MSL 1 (Unlimited) rating, meaning they have unlimited shelf life and do not require special moisture-controlled storage or handling procedures.

Q: Are the electrical specifications identical?

A: Yes. Both parts have identical capacitance (4.4 pF), tolerance (±0.25pF), voltage rating (50V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 125°C). They are electrically interchangeable.

Q: What is the difference between the series designations (MBAS vs. M)?

A: Series designation reflects internal Taiyo Yuden product line organization. This difference does not affect electrical performance, mechanical compatibility, or substitution eligibility. Both parts meet identical specifications for the 4.4 pF 50V C0G/NP0 0201 ceramic capacitor category.
