MMASU063SCG9R9DFNA01 Equivalent & Substitute Parts

Part Overview

The MMASU063SCG9R9DFNA01 is a 9.9 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 unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when inventory constraints occur, when design requirements shift toward automotive-qualified components, or when transitioning from active to legacy product lines while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMASU063SCG9R9DFNA01 is determined by strict alignment across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 9.9 pF
• Tolerance: ±0.5pF
• Voltage rating: 50V minimum
• Temperature coefficient: C0G/NP0

Mechanical Parameters (Non-Negotiable):

• Package: 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 required
• MSL rating: 1 (Unlimited)

The substitute part UMK063CG9R9DTHF meets all electrical, mechanical, and compliance requirements. The primary distinction is product status and application qualification: the substitute carries AEC-Q200 automotive qualification and is designated "Not For New Designs," whereas the main part is Active and targets medical/non-critical applications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Active Production: Select MMASU063SCG9R9DFNA01. This part carries Active product status, ensuring long-term availability and manufacturer support. It is suitable for medical and non-critical applications without automotive qualification requirements.

For Automotive Applications or AEC-Q200 Compliance: The UMK063CG9R9DTHF substitute is qualified to AEC-Q200 automotive standards. However, this part is designated "Not For New Designs," indicating it is in legacy status. Use this substitute only when existing designs require automotive-qualified components or when MMASU063SCG9R9DFNA01 inventory is unavailable and automotive qualification is mandatory.

Compliance Considerations: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, eliminating compliance barriers to substitution. Both are manufactured by Taiyo Yuden, ensuring consistent quality and reliability standards.

Inventory and Availability: MMASU063SCG9R9DFNA01 maintains 1094 pieces in stock (Active status). UMK063CG9R9DTHF maintains 827 pieces in stock (legacy status). Substitution should be driven by application requirements rather than inventory levels alone.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG9R9DTHF be used as a direct replacement for MMASU063SCG9R9DFNA01 in medical device applications?

A: Electrically and mechanically, yes. Both parts are identical in capacitance (9.9 pF), tolerance (±0.5pF), voltage rating (50V), temperature coefficient (C0G/NP0), package (0201), and compliance (ROHS3, MSL 1). However, UMK063CG9R9DTHF carries AEC-Q200 automotive qualification and "Not For New Designs" status. Medical applications should use MMASU063SCG9R9DFNA01 (Active status) unless automotive qualification is specifically required.

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

A: No. Both parts share identical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), maximum thickness (0.013" / 0.33mm), and 0201 (0603 Metric) package specification. They are physically interchangeable on PCB layouts and compatible with identical assembly equipment.

Q: What does "Not For New Designs" mean for the UMK063CG9R9DTHF?

A: This designation indicates the part is in legacy or end-of-life status. The manufacturer does not recommend using this part in new product designs. It remains available for existing designs and legacy production support. For new designs, MMASU063SCG9R9DFNA01 (Active status) is the appropriate selection.

Q: Do both parts require the same storage and handling procedures?

A: Yes. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, meaning they have unlimited shelf life under normal storage conditions and do not require special moisture control during storage or handling.

Q: Can I substitute MMASU063SCG9R9DFNA01 with UMK063CG9R9DTHF in a non-automotive application?

A: Electrically and mechanically, substitution is valid. However, using an automotive-qualified part (AEC-Q200) in a non-automotive application is unnecessary and may increase component cost. Use MMASU063SCG9R9DFNA01 for non-automotive applications unless inventory constraints or design requirements dictate otherwise.

Q: What is the significance of the C0G/NP0 temperature coefficient for these capacitors?

A: C0G/NP0 temperature coefficient indicates minimal capacitance variation across the operating temperature range (-55°C ~ 125°C). Both parts maintain this specification, ensuring stable circuit performance across the full temperature envelope. This is critical for precision analog circuits and frequency-dependent applications.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are specified identically for capacitance (9.9 pF ±0.5pF), voltage rating (50V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 125°C). Electrical performance is equivalent.
