MBASU063SCG2R8CFNA01 Equivalent & Substitute Parts

Part Overview

The MBASU063SCG2R8CFNA01 is a 2.8 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 form factor (0603 metric) and is designated for general purpose applications. The part is currently in active product status with 890 units available in inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design requirements shift toward parts with enhanced certifications such as automotive-grade qualifications. The substitute identified for this capacitor maintains electrical and mechanical compatibility while offering alternative availability and application scope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBASU063SCG2R8CFNA01 is determined by strict equivalence across the following parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 2.8 pF
• Tolerance: ±0.25pF
• 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
• Size / Dimension: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Thickness (Max): 0.013" (0.33mm)

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part UMK063CG2R8CTHF meets all electrical and mechanical equivalence criteria. The substitute differs in product status (Not For New Designs versus Active) and includes automotive-grade AEC-Q200 certification, which represents an enhancement rather than a deviation from the original specification set.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs: The MBASU063SCG2R8CFNA01 remains the primary selection. This part carries Active product status, indicating ongoing manufacturer support and availability. It is suitable for general purpose applications and meets all ROHS3 compliance requirements.

For Automotive Applications: The UMK063CG2R8CTHF substitute is appropriate when automotive-grade certification is required. This part carries AEC-Q200 rating, which qualifies it for automotive environments. However, this part is designated as Not For New Designs, indicating it is in transition toward obsolescence. Use of this part should be limited to legacy design support or applications where existing qualification data references this specific part number.

Inventory and Availability Considerations: The main part (MBASU063SCG2R8CFNA01) has 890 units in stock. The substitute (UMK063CG2R8CTHF) has 1234 units available. Both parts are sourced from the same manufacturer (Taiyo Yuden) and maintain identical electrical and mechanical specifications, ensuring direct functional interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG2R8CTHF be used as a direct replacement for MBASU063SCG2R8CFNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 2.8 pF capacitance, ±0.25pF tolerance, 50V rating, C0G/NP0 temperature coefficient, -55°C to 125°C operating range, and 0201 (0603 metric) package form factor. Direct substitution is supported from a technical compatibility standpoint.

Q: What is the significance of the "Not For New Designs" status on the UMK063CG2R8CTHF?

A: This designation indicates the manufacturer is phasing out this part number. While the part remains functionally equivalent and available, it should not be selected for new product development. This status is informational and does not affect the electrical or mechanical performance of the part in existing applications.

Q: Why does the substitute part have AEC-Q200 certification while the main part does not?

A: AEC-Q200 is an automotive-grade qualification standard. The substitute part (UMK063CG2R8CTHF) is qualified for automotive applications, whereas the main part (MBASU063SCG2R8CFNA01) is designated for general purpose use. Both parts meet identical electrical specifications; the certification difference reflects the intended application scope rather than a performance difference.

Q: Are there any dimensional differences between these two parts?

A: No. Both parts share identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with a maximum thickness of 0.013" (0.33mm). They are both packaged in 0201 (0603 metric) form factor and are surface mount MLCCs. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both parts carry MSL 1 (Unlimited), which indicates no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly, simplifying logistics and manufacturing processes.

Q: Can these parts be used interchangeably in high-frequency or RF applications?

A: Substitution eligibility is determined strictly by the electrical and mechanical parameters provided. Both parts are specified identically for capacitance, tolerance, voltage rating, and temperature coefficient. Application-specific performance in high-frequency or RF circuits depends on factors not included in the provided parameter set and must be evaluated separately against circuit requirements.
