MMASU063SCG0R6CFNA01 Equivalent & Substitute Parts

Part Overview

The MMASU063SCG0R6CFNA01 is a 0.6 pF ceramic capacitor manufactured by Taiyo Yuden, designed for surface mount applications in the 0201 (0603 Metric) package. This multilayer ceramic capacitor (MLCC) operates at 50V with C0G/NP0 temperature coefficient characteristics, suitable for medical and non-critical applications. The part is currently in active product status with 714 units available in inventory.

Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements permit selection from alternative qualified sources. The substitute identified maintains electrical and mechanical compatibility while offering different product lifecycle status and application certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the MMASU063SCG0R6CFNA01 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters:

• Capacitance value: 0.6 pF
• Capacitance tolerance: ±0.25pF
• Rated voltage: 50V
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters:

• Package type: 0201 (0603 Metric)
• Mounting configuration: 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
• Moisture Sensitivity Level 1

The substitute part UMK063CG0R6CTHF meets all electrical and mechanical requirements for direct substitution. Differences exist in product lifecycle status, series designation, and application certifications, which do not affect functional compatibility in equivalent circuit applications.

Engineering Selection Recommendations

Primary Part Selection (MMASU063SCG0R6CFNA01): Select the primary part for new designs and applications where active product status and medical/non-critical application support are required. This part maintains current manufacturing support and is recommended for long-term production programs.

Substitute Part Selection (UMK063CG0R6CTHF): The UMK063CG0R6CTHF is electrically and mechanically equivalent and may be selected when the primary part is unavailable. This substitute carries AEC-Q200 automotive qualification, indicating automotive-grade reliability standards. However, the part is designated "Not For New Designs," indicating it is in end-of-life or legacy status. Selection of this substitute is appropriate for:

• Replacement or repair of existing assemblies
• Situations where primary part inventory is depleted
• Applications where automotive-grade qualification provides additional assurance

Both parts are ROHS3 compliant and carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG0R6CTHF be used as a direct replacement for MMASU063SCG0R6CFNA01?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 0.6 pF capacitance, ±0.25pF tolerance, 50V rating, C0G/NP0 temperature coefficient, -55°C to 125°C operating range, and 0201 (0603 Metric) package. They are pin-compatible and footprint-compatible for surface mount assembly.

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

A: This designation indicates the UMK063CG0R6CTHF is in legacy or end-of-life phase. While the part remains functionally equivalent and available in inventory, Taiyo Yuden does not recommend it for new product development. New designs should prioritize the MMASU063SCG0R6CFNA01 (Active status) to ensure long-term supply continuity.

Q: Are there differences in reliability between these parts?

A: The substitute part carries AEC-Q200 automotive qualification, which certifies automotive-grade reliability standards. The primary part is specified for medical and non-critical applications. Both parts meet ROHS3 compliance and MSL 1 requirements. Selection between them should be based on application requirements and product lifecycle strategy rather than reliability differences.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Identical handling, storage, and assembly procedures apply to both parts.

Q: Can the substitute part be used in medical applications?

A: The UMK063CG0R6CTHF is specified for automotive applications and carries AEC-Q200 qualification. While electrically equivalent, medical application requirements may impose additional qualification or documentation requirements beyond the part's specified application scope. Application suitability should be confirmed with design and quality requirements.

Q: What inventory considerations apply to these parts?

A: The primary part (MMASU063SCG0R6CFNA01) has 714 units in stock. The substitute part (UMK063CG0R6CTHF) has significantly higher inventory at 24,958 units. For high-volume production or extended lead-time mitigation, the substitute offers greater availability, though its legacy status should be considered for long-term programs.
