MMASU063SCG1R1CFNA01 Equivalent & Substitute Parts

Part Overview

The MMASU063SCG1R1CFNA01 is a 1.1 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 designed for medical and non-critical applications. The part maintains an Active product status with full RoHS3 compliance and MSL 1 moisture sensitivity rating.

Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements shift toward alternative qualification standards such as automotive-grade certifications. The substitute identified maintains electrical and mechanical compatibility while offering different application focus and product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMASU063SCG1R1CFNA01 is determined by strict alignment of the following parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 1.1 pF
• Tolerance: ±0.25pF
• Voltage rating: 50V minimum
• Temperature coefficient: C0G/NP0

Mechanical Parameters (Non-Negotiable):

• Package: 0201 (0603 Metric)
• Mounting: Surface Mount, MLCC

Environmental & Compliance Parameters (Required):

• Operating temperature range: -55°C ~ 125°C minimum
• RoHS3 compliance
• MSL 1 rating

The identified substitute part UMK063CG1R1CTHF satisfies all mandatory electrical and mechanical parameters. The primary distinction lies in product lifecycle status and application qualification: the substitute carries AEC-Q200 automotive qualification and holds "Not For New Designs" status, whereas the main part maintains Active status for medical and non-critical applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MMASU063SCG1R1CFNA01): Select the main part for new designs and applications requiring Active product status. This part is suitable for medical and non-critical applications with standard environmental compliance requirements. The Active status ensures continued manufacturer support and long-term availability.

Substitute Part Selection (UMK063CG1R1CTHF): The substitute part is electrically and mechanically equivalent and may be used in existing designs where supply of the primary part is constrained. However, the "Not For New Designs" status indicates this part is in end-of-life phase. The AEC-Q200 automotive qualification of the substitute provides additional reliability assurance for applications requiring automotive-grade components, though this qualification is not required for the primary application focus.

Compliance Considerations: Both parts maintain ROHS3 compliance and MSL 1 rating. No compliance degradation occurs with substitution. The substitute's automotive qualification does not impose additional restrictions on use in non-automotive applications.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG1R1CTHF be used as a direct replacement for MMASU063SCG1R1CFNA01?

A: Yes, for existing designs. All electrical parameters (capacitance, tolerance, voltage, temperature coefficient), mechanical dimensions, and environmental ratings are identical. The parts are pin-compatible and footprint-compatible in 0201 (0603 Metric) package format.

Q: What does "Not For New Designs" status mean for the substitute part?

A: This designation indicates the substitute part is in end-of-life phase and the manufacturer does not recommend its use in new product designs. Existing inventory may be available, but long-term supply cannot be guaranteed. For new designs, the primary part MMASU063SCG1R1CFNA01 with Active status is the appropriate selection.

Q: Are there differences in reliability between the two parts?

A: Both parts are manufactured by Taiyo Yuden with identical electrical specifications and operating temperature ranges. The substitute carries AEC-Q200 automotive qualification, which indicates additional reliability testing and qualification. For non-automotive applications, both parts meet the specified requirements.

Q: Does the substitute part's automotive qualification affect its use in medical applications?

A: No. AEC-Q200 qualification is an additional qualification level that does not restrict use in other applications. The substitute part remains fully compatible with medical and non-critical applications from an electrical and mechanical standpoint.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. Both parts can be stored and handled under standard conditions without special moisture control procedures, simplifying inventory management and assembly processes.

Q: Are there any packaging differences between the main part and substitute?

A: Both parts are supplied in Tape & Reel (TR) packaging format. Physical dimensions, thickness, and all mechanical specifications are identical. No PCB layout or assembly process modifications are required for substitution.

Q: Can the substitute part be used in temperature-critical applications?

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. Temperature performance is equivalent between the two parts.
