MMASU063SCG3R7CFNA01 Equivalent & Substitute Parts

Part Overview

The MMASU063SCG3R7CFNA01 is a 3.7 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 designated for medical and non-critical applications. The part maintains an Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts become necessary when inventory constraints occur, when design requirements shift toward automotive-qualified components, or when alternative sourcing from the same manufacturer's product lines is preferred.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMASU063SCG3R7CFNA01 is based on strict electrical and mechanical parameter matching. The substitute part UMK063CG3R7CTHF maintains identical specifications across all critical parameters: capacitance value of 3.7 pF, tolerance of ±0.25pF, voltage rating of 50V, C0G/NP0 temperature coefficient, operating temperature range of -55°C to 125°C, and 0201 (0603 Metric) package configuration. Both parts are manufactured by Taiyo Yuden and employ surface-mount MLCC technology.

The key parameters that determine substitution eligibility are:

• Capacitance value and tolerance
• Voltage rating
• Temperature coefficient type
• Operating temperature range
• Physical package dimensions and form factor
• Mounting technology (surface mount)
• RoHS3 compliance status
• Moisture sensitivity classification

The substitute part differs in product status (Not For New Designs versus Active) and includes automotive-grade AEC-Q200 certification, which represents an enhancement rather than a limitation for general applications.

Parameter Comparison

Engineering Selection Recommendations

The UMK063CG3R7CTHF serves as a direct electrical and mechanical substitute for the MMASU063SCG3R7CFNA01. All critical performance parameters align without deviation. Both parts maintain ROHS3 compliance and identical moisture sensitivity classification, ensuring equivalent handling and storage requirements.

For new design implementations, the MMASU063SCG3R7CFNA01 is the preferred selection due to its Active product status, which ensures long-term availability and manufacturer support. The MMASU series is actively manufactured and recommended for ongoing production.

The UMK063CG3R7CTHF, while electrically and mechanically identical, carries a "Not For New Designs" designation. However, this part includes AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring enhanced environmental and stress testing compliance. This substitute is suitable for replacement in existing designs, field service applications, or situations where automotive-grade components are beneficial.

Selection between these parts should be based on design phase (new versus existing), inventory availability, and whether automotive-grade certification adds value to the application. Both parts are manufactured by Taiyo Yuden and are sourced from the same product family, ensuring consistent quality and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG3R7CTHF be used as a direct replacement for MMASU063SCG3R7CFNA01 in existing designs?

A: Yes. All electrical parameters (capacitance, tolerance, voltage rating, temperature coefficient, and operating temperature range) are identical. Physical dimensions and mounting characteristics match exactly. The substitute part is mechanically and electrically compatible with the original part's PCB footprint and circuit function.

Q: What is the significance of the "Not For New Designs" status on the UMK063CG3R7CTHF?

A: This designation indicates that Taiyo Yuden does not recommend this part for new product development. However, it remains available for replacement and field service applications. For new designs, the MMASU063SCG3R7CFNA01 (Active status) is the recommended choice to ensure long-term manufacturer support and availability.

Q: Does the AEC-Q200 certification on UMK063CG3R7CTHF provide any functional advantage?

A: AEC-Q200 is an automotive industry qualification standard that certifies the part has undergone enhanced reliability testing and environmental stress screening. While this does not change the electrical performance of the capacitor, it provides additional assurance of quality and reliability. For non-automotive applications, this certification is not required but does not present any disadvantage.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both parts use the 0201 (0603 Metric) package with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). They are physically interchangeable on PCB layouts designed for this package size.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited) rating, which means they have unlimited shelf life under normal storage conditions and do not require special moisture-controlled storage or baking procedures prior to assembly.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MMASU063SCG3R7CFNA01 and UMK063CG3R7CTHF are ROHS3 compliant, meeting all current regulatory requirements for hazardous substance restrictions.

Q: Can these parts be used interchangeably in medical applications?

A: The MMASU063SCG3R7CFNA01 is specified for medical and non-critical applications. The UMK063CG3R7CTHF is specified for automotive applications. While both parts have identical electrical and mechanical specifications, application-specific qualification and regulatory approval should be verified with the end-use system manufacturer before substitution in medical devices.
