Substitute Part Grouping Explanation

Substitution of ceramic capacitors is determined by strict equivalence across electrical and mechanical parameters. The MBASU063SCG2R1CFNA01 can be substituted with parts that maintain identical specifications in the following critical areas:

Electrical Parameters:

• Capacitance value: 2.1 pF
• Tolerance: ±0.25pF
• Voltage rating: 50V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 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

The substitute part UMK063CG2R1CTHF meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Engineering Selection Recommendations

MBASU063SCG2R1CFNA01 (Primary Selection)

The MBASU063SCG2R1CFNA01 is the recommended part for new designs and ongoing production. This part maintains Active product status from Taiyo Yuden, ensuring long-term availability and supply chain stability. It is suitable for general purpose applications and carries full ROHS3 compliance with MSL 1 rating.

UMK063CG2R1CTHF (Substitute Selection)

The UMK063CG2R1CTHF is electrically and mechanically equivalent to the main part number and serves as a direct substitute. However, this part carries a "Not For New Designs" status, indicating it is in a mature or transitional phase of its product lifecycle. The UMK063CG2R1CTHF includes AEC-Q200 automotive qualification and is designated for automotive applications, whereas the MBASU063SCG2R1CFNA01 is specified for general purpose use. Both parts maintain identical electrical performance, package dimensions, and compliance certifications. Selection between these parts should be based on application requirements and product lifecycle considerations rather than electrical or mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG2R1CTHF be used as a direct replacement for MBASU063SCG2R1CFNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical in all critical parameters: 2.1 pF capacitance, ±0.25pF tolerance, 50V rating, C0G/NP0 temperature coefficient, 0201 package, and identical physical dimensions. They are pin-compatible and footprint-compatible with no design modifications required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and application designation. MBASU063SCG2R1CFNA01 is Active and specified for general purpose applications. UMK063CG2R1CTHF is marked "Not For New Designs" and includes AEC-Q200 automotive qualification for automotive applications. Electrically and mechanically, they are equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MBASU063SCG2R1CFNA01 and UMK063CG2R1CTHF are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts share identical 0201 (0603 Metric) package specifications with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). They use identical surface mount assembly processes and require no PCB footprint modifications.

Q: Which part should be selected for new product designs?

A: MBASU063SCG2R1CFNA01 is the appropriate selection for new designs due to its Active product status, ensuring continued manufacturer support and supply availability. UMK063CG2R1CTHF should be reserved for applications requiring automotive qualification or for existing designs already qualified to this part number.

Q: Do these capacitors have identical temperature performance?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C with C0G/NP0 temperature coefficient, ensuring stable capacitance performance across the full operating range.
