Substitute Part Grouping Explanation

Substitute parts for the MMASU063SCG3R5CFNA01 are identified through strict parameter matching across the following criteria:

Electrical Compatibility Requirements:

• Capacitance value: 3.5 pF (exact match)
• Capacitance tolerance: ±0.25 pF (exact match)
• Voltage rating: 50V (exact match or higher)
• Temperature coefficient: C0G/NP0 (exact match for stability)
• Operating temperature range: -55°C to 125°C (exact match)

Mechanical Compatibility Requirements:

• Package type: 0201 (0603 Metric) (exact match)
• Mounting type: Surface Mount, MLCC (exact match)
• Moisture sensitivity: MSL 1 (Unlimited) (exact match)

Compliance Requirements:

• RoHS3 Compliant status (maintained)

The substitute part UMK063CG3R5CTHF meets all electrical and mechanical parameters while differing in product lifecycle status and application certification focus.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MMASU063SCG3R5CFNA01): The MMASU063SCG3R5CFNA01 is recommended for new designs requiring a 3.5 pF, 50V ceramic capacitor in 0201 package format. This part maintains Active product status, ensuring long-term availability and supply chain stability. The part is ROHS3 compliant and carries MSL 1 rating, indicating minimal moisture sensitivity concerns. Current inventory of 858 pieces supports immediate procurement requirements.

Substitute Part Selection (UMK063CG3R5CTHF): The UMK063CG3R5CTHF provides functional equivalence across all electrical and mechanical parameters. However, this part carries "Not For New Designs" status, indicating it is in end-of-life phase. The UMK063CG3R5CTHF includes AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. This part should be selected only when automotive certification is a specific requirement or when the primary part is unavailable. Higher inventory availability (4621 pieces) may support legacy design support or high-volume requirements.

Compliance Considerations: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts should be driven by product lifecycle requirements and application-specific certifications rather than environmental compliance factors.

Frequently Asked Questions (FAQ)

Q: Can the UMK063CG3R5CTHF be used as a direct replacement for the MMASU063SCG3R5CFNA01?

A: Yes, the UMK063CG3R5CTHF provides direct functional equivalence. All electrical specifications (capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range) and mechanical parameters (package dimensions, mounting type, moisture sensitivity) are identical. The parts are interchangeable at the circuit level.

Q: What is the significance of the "Not For New Designs" status on the UMK063CG3R5CTHF?

A: "Not For New Designs" indicates the part is in end-of-life phase and the manufacturer does not recommend its use in new product development. This status does not affect functional performance but signals that long-term availability may be limited. New designs should prioritize the MMASU063SCG3R5CFNA01, which carries Active status.

Q: Does the AEC-Q200 certification on the UMK063CG3R5CTHF provide additional benefits for non-automotive applications?

A: AEC-Q200 is an automotive-specific qualification standard. For non-automotive applications, this certification provides no functional advantage. Selection should be based on application requirements rather than certification presence.

Q: Are there any dimensional differences between these parts?

A: No. Both parts share identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum thickness of 0.013" (0.33mm). They are fully compatible in 0201 (0603 Metric) footprints.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 are equivalent designations for the same temperature coefficient classification. Both terms describe capacitors with negligible capacitance change across the operating temperature range (-55°C to 125°C). The terminology difference reflects regional naming conventions; the electrical performance is identical.

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

A: The MMASU063SCG3R5CFNA01 is specified for medical and non-critical applications. The UMK063CG3R5CTHF is specified for automotive applications. While both parts meet identical electrical and mechanical specifications, application-specific certifications and design qualifications may differ. Medical application use should be validated against specific design requirements and regulatory standards.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Parts with MSL 1 rating have unlimited shelf life under normal storage conditions and do not require special moisture control during handling or assembly. Both parts carry this rating, eliminating moisture-related compatibility concerns.

Q: Are both parts available in the same packaging format?

A: Yes. Both the MMASU063SCG3R5CFNA01 and UMK063CG3R5CTHF are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
