MLASU063SCG201JFNA01 Equivalent & Substitute Parts

Part Overview

The MLASU063SCG201JFNA01 is a 200 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 725 pieces currently in stock.

Substitute parts become necessary when primary inventory is depleted, when design flexibility permits alternative qualified sources, or when production timelines require access to higher-volume alternatives. The UMK063CG201JT-F represents a parametrically equivalent option, though it carries a Not For New Designs status and is designated for general-purpose applications rather than medical use.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLASU063SCG201JFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 200 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 50V (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)

Mechanical Parameters:

• Package type: 0201 (0603 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 0.024" L x 0.012" W; 0.013" max thickness (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (exact match required)
• Moisture Sensitivity Level 1 (exact match required)
• REACH Unaffected status (exact match required)

The UMK063CG201JT-F meets all electrical, mechanical, and compliance requirements for direct substitution at the component level. Application-specific requirements (medical versus general-purpose designation) and product lifecycle status (Active versus Not For New Designs) are secondary considerations that do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: MLASU063SCG201JFNA01

The MLASU063SCG201JFNA01 is the preferred component for new designs and ongoing production. It carries Active product status, indicating full manufacturer support and continued availability. The part is specifically qualified for medical and non-critical applications, providing appropriate certification for regulated environments. Current inventory of 725 pieces supports immediate procurement requirements.

Substitute Selection: UMK063CG201JT-F

The UMK063CG201JT-F is electrically and mechanically equivalent to the primary part and is suitable for substitution when the MLASU063SCG201JFNA01 is unavailable. This part carries Not For New Designs status, indicating it is maintained for legacy production and existing designs only. The UMK063CG201JT-F is classified for general-purpose applications rather than medical use; however, it maintains identical electrical performance, mechanical compatibility, and regulatory compliance (ROHS3 Compliant, REACH Unaffected).

The substantially higher inventory level (77,750 pieces) for the UMK063CG201JT-F may provide supply chain advantages for high-volume production scenarios where application-specific medical qualification is not a design requirement.

Both parts are manufactured by Taiyo Yuden and share identical packaging, compliance certifications, and performance specifications across all critical electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the UMK063CG201JT-F be used as a direct replacement for the MLASU063SCG201JFNA01 in existing designs?

A: Yes. The UMK063CG201JT-F is electrically and mechanically equivalent. Both parts have identical capacitance (200 pF), tolerance (±5%), voltage rating (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (0201/0603 Metric), and physical dimensions. Both are ROHS3 Compliant with Moisture Sensitivity Level 1. The primary difference is product lifecycle status and application classification; the UMK063CG201JT-F is designated Not For New Designs and for general-purpose use rather than medical applications.

Q: Are there any physical compatibility issues between these two parts?

A: No. Both parts are identical in physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum thickness of 0.013" (0.33mm). Both use surface-mount MLCC mounting technology in the 0201 (0603 Metric) package. They are mechanically interchangeable on PCB layouts designed for either part number.

Q: What is the significance of the "Not For New Designs" status on the UMK063CG201JT-F?

A: This designation indicates that Taiyo Yuden does not recommend the UMK063CG201JT-F for new product development. The part is maintained for legacy production and existing designs only. For new designs, the MLASU063SCG201JFNA01 (Active status) is the appropriate selection. However, the UMK063CG201JT-F remains fully functional and compliant for substitution in existing applications.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts have identical Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Both parts can be stored and handled under standard conditions without special moisture control measures.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the MLASU063SCG201JFNA01 and UMK063CG201JT-F are ROHS3 Compliant and REACH Unaffected. Both carry identical regulatory compliance status and are suitable for applications subject to these requirements.

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

A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic. Both terms describe a capacitor with negligible capacitance change across the operating temperature range (-55°C ~ 125°C). The terminology difference reflects regional naming conventions; C0G is the EIA standard designation, while NP0 is the IEC standard designation. Both parts use this identical specification.

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

A: The MLASU063SCG201JFNA01 is specifically qualified for medical and non-critical applications. The UMK063CG201JT-F is designated for general-purpose use. While both parts are electrically and mechanically identical, application-specific medical qualification may be required by design standards or regulatory frameworks. Design requirements should determine whether the medical-qualified MLASU063SCG201JFNA01 is necessary or whether the general-purpose UMK063CG201JT-F is acceptable.
