Substitute Part Grouping Explanation

Substitution of the MMASU063SCG5R9DFNA01 is determined by strict equivalence across electrical and mechanical parameters. The primary substitute identified is the UMK063CG5R9DTHF, which maintains identical specifications for capacitance (5.9 pF), tolerance (±0.5pF), rated voltage (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (0201/0603 Metric), mounting configuration (Surface Mount MLCC), physical dimensions (0.024" L x 0.012" W), maximum thickness (0.013"), moisture sensitivity level (MSL 1), and RoHS compliance (ROHS3).

The key parameters governing substitution eligibility are:

• Capacitance value and tolerance band
• Voltage rating
• Temperature coefficient classification
• Operating temperature range
• Package and case designation
• Physical dimensions and thickness
• Moisture sensitivity rating
• Regulatory compliance status

Engineering Selection Recommendations

The MMASU063SCG5R9DFNA01 is the primary selection for new designs requiring a 5.9 pF, 50V ceramic capacitor in 0201 package format. This part carries Active product status, ensuring long-term availability and manufacturing support.

The UMK063CG5R9DTHF serves as an electrical and mechanical equivalent with identical capacitance, voltage rating, temperature coefficient, and physical specifications. However, this part is designated as Not For New Designs. The UMK063CG5R9DTHF carries AEC-Q200 automotive qualification and is targeted for automotive applications, whereas the MMASU063SCG5R9DFNA01 is specified for medical and non-critical applications.

Selection between these parts should be based on application requirements and product lifecycle phase. For new designs, the MMASU063SCG5R9DFNA01 is the appropriate choice. For existing designs or applications requiring automotive-grade qualification, the UMK063CG5R9DTHF provides electrical equivalence with automotive compliance certification.

Both parts maintain ROHS3 compliance, MSL 1 rating, and identical physical dimensions, ensuring direct substitution at the board level without design modification.

Frequently Asked Questions (FAQ)

Q: Can the UMK063CG5R9DTHF be used as a direct replacement for the MMASU063SCG5R9DFNA01?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical capacitance (5.9 pF), tolerance (±0.5pF), voltage rating (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (0201/0603 Metric), and physical dimensions. However, the UMK063CG5R9DTHF carries Not For New Designs status, so the MMASU063SCG5R9DFNA01 is preferred for new product development.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance value and tolerance, rated voltage, temperature coefficient, and operating temperature range must be identical. All four parameters are matched between the MMASU063SCG5R9DFNA01 and UMK063CG5R9DTHF.
