MLASU063SCG910JFNA01 Equivalent & Substitute Parts

Part Overview

The MLASU063SCG910JFNA01 is a 91 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 classified as Active product status for medical and non-critical applications.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements shift toward components with enhanced certifications such as automotive-grade qualifications. The substitute parts listed maintain identical electrical and mechanical specifications while offering alternative sourcing options and compliance profiles.

Substitute Part Grouping Explanation

Substitution eligibility for the MLASU063SCG910JFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 91 pF (exact match)
• Tolerance: ±5% (exact match)
• Voltage rating: 50V (exact match or higher)
• Temperature coefficient: C0G/NP0 (exact match)
• Operating temperature range: -55°C ~ 125°C (exact match or wider)

Mechanical Equivalence Requirements:

• Package type: 0201 (0603 Metric) (exact match)
• Mounting type: Surface Mount, MLCC (exact match)
• Physical dimensions: 0.024" L x 0.012" W; 0.013" max thickness (exact match)
• Moisture sensitivity level: 1 (Unlimited) (exact match)

Compliance Requirements:

• RoHS3 compliance (maintained across all substitutes)
• ECCN: EAR99 (maintained across all substitutes)
• HTSUS: 8532.24.0020 (maintained across all substitutes)

The substitute parts UMK063CG910JTHF and UMK063CG910JT-F meet all electrical and mechanical equivalence criteria. Differences in product status, application classification, and ratings certifications do not affect functional interchangeability in circuits designed for the MLASU063SCG910JFNA01.

Parameter Comparison

Engineering Selection Recommendations

For Active Design Programs: The MLASU063SCG910JFNA01 remains the primary selection for new designs due to its Active product status. This part is currently manufactured and supported by Taiyo Yuden with full availability.

For Automotive Applications: The UMK063CG910JTHF substitute is qualified to AEC-Q200 automotive standards and is suitable for automotive circuit implementations. This part carries automotive-grade reliability ratings despite its "Not For New Designs" status, indicating it remains available for existing production lines and legacy system support.

For General Purpose and Legacy Applications: The UMK063CG910JT-F substitute provides parametric equivalence for general purpose applications and serves as an alternative sourcing option when primary inventory is constrained. This part is classified as "Not For New Designs" but maintains full electrical and mechanical compatibility.

Compliance Considerations: All three parts maintain ROHS3 compliance, EAR99 ECCN classification, and identical HTSUS coding. Selection between these parts does not introduce compliance complications in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can UMK063CG910JTHF be used as a direct replacement for MLASU063SCG910JFNA01 in existing designs?

A: Yes. The UMK063CG910JTHF maintains identical electrical specifications (91 pF, ±5%, 50V, C0G/NP0), operating temperature range (-55°C ~ 125°C), and mechanical package (0201/0603 Metric). The AEC-Q200 automotive qualification of the substitute does not restrict its use in non-automotive applications. Direct substitution is electrically and mechanically valid.

Q: What is the difference between UMK063CG910JTHF and UMK063CG910JT-F?

A: Both parts are parametrically identical in capacitance, voltage, tolerance, temperature coefficient, package, and physical dimensions. The primary differences are application classification (Automotive vs. General Purpose) and ratings certification (AEC-Q200 vs. unspecified). Both are manufactured by Taiyo Yuden and carry "Not For New Designs" status. Selection between them depends on application requirements and inventory availability.

Q: Are there any thermal or frequency performance differences between these substitutes?

A: No thermal or frequency performance parameters are provided in the component specifications. All three parts share identical temperature coefficient (C0G/NP0) and operating temperature range (-55°C ~ 125°C). Thermal and frequency characteristics are equivalent across all listed parts.

Q: Can these 0201 package capacitors be used interchangeably on the same PCB assembly?

A: Yes. All three parts use identical 0201 (0603 Metric) package dimensions: 0.024" L x 0.012" W with 0.013" maximum thickness. PCB footprints, solder pad layouts, and pick-and-place machine settings are directly interchangeable.

Q: What does "Not For New Designs" status mean for the substitute parts?

A: "Not For New Designs" indicates that Taiyo Yuden is not recommending these parts for incorporation into newly developed products. However, this status does not affect electrical or mechanical performance. These parts remain available for production support of existing designs and legacy systems. The MLASU063SCG910JFNA01 with Active status is the recommended choice for new product development.

Q: Are moisture sensitivity considerations identical across all three parts?

A: Yes. All three parts carry Moisture Sensitivity Level (MSL) 1, classified as "Unlimited." This indicates no moisture-related handling restrictions during storage, transportation, or assembly processes.
