MSAST063SCG301JFNA01 Equivalent & Substitute Parts

Part Overview

The MSAST063SCG301JFNA01 is a 300 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V 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 general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C.

The primary part is currently in Active product status with 795 pieces available in stock. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate alternative sourcing options when the primary part becomes unavailable or when design revisions require component optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the MSAST063SCG301JFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 300 pF
• Tolerance: ±5%
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 0201 (0603 Metric)
• Mounting type: 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
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all these criteria are classified as direct parametric equivalents and can be substituted without circuit redesign or board layout modification.

Engineering Selection Recommendations

Primary Part Selection: The MSAST063SCG301JFNA01 is the recommended choice for new designs. This part maintains Active product status, indicating ongoing manufacturer support, continued availability, and compliance with current industry standards. With 795 pieces in stock, supply continuity is established for immediate procurement requirements.

Substitute Part Consideration: The TMK063CG301JT-F is a parametric equivalent that satisfies all electrical, mechanical, and compliance requirements. However, this part carries a "Not For New Designs" product status designation. This classification indicates that while the part remains functionally equivalent and available (83,517 pieces in stock), the manufacturer has discontinued active development and support for this product line.

Application Context: For new product development, the MSAST063SCG301JFNA01 is the appropriate selection. The TMK063CG301JT-F substitute is suitable for legacy system maintenance, field replacements, or situations where existing inventory must be utilized. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for commercial and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can TMK063CG301JT-F be used as a direct replacement for MSAST063SCG301JFNA01 in existing designs?

A: Yes. Both parts are parametrically identical across all electrical, mechanical, and compliance specifications. Direct substitution is possible without circuit modification or board layout changes. The physical dimensions, capacitance value, voltage rating, temperature coefficient, and package type are identical.

Q: What does "Not For New Designs" mean for the TMK063CG301JT-F?

A: This designation indicates that Taiyo Yuden has discontinued active development and support for this product line. The part remains available and functional, but new product designs should utilize the MSAST063SCG301JFNA01 instead to ensure long-term manufacturer support and supply chain stability.

Q: Are there any differences in performance between these two parts?

A: No. Both parts operate identically within the specified parameters. The capacitance tolerance (±5%), voltage rating (25V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 125°C) are identical. Performance in circuit applications is equivalent.

Q: Can these parts be used interchangeably on the same printed circuit board?

A: Yes. The 0201 (0603 Metric) package dimensions are identical for both parts: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum thickness of 0.013" (0.33mm). Board layout, footprint design, and pick-and-place programming require no modification.

Q: What is the significance of the Moisture Sensitivity Level 1 rating?

A: MSL 1 (Unlimited) indicates that these capacitors have unlimited shelf life and require no special moisture control during storage or handling. Standard industrial storage conditions are sufficient. No baking or desiccant packaging is required prior to assembly.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the MSAST063SCG301JFNA01 and TMK063CG301JT-F are ROHS3 compliant and REACH unaffected. They meet current environmental and hazardous substance restrictions for commercial, industrial, and consumer applications.
