MSAST042SCG050CWNA01 Equivalent & Substitute Parts

Part Overview

The MSAST042SCG050CWNA01 is a 5 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 01005 (0402 Metric) package is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts are identified to provide design flexibility, supply chain alternatives, and component availability options while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the MSAST042SCG050CWNA01 are qualified based on strict electrical and mechanical parameter matching. The substitution criteria are defined by the following parameters:

Critical Matching Parameters:

• Capacitance value: 5 pF
• Capacitance tolerance: ±0.25pF
• Voltage rating: 25V
• Temperature coefficient: C0G, NP0
• Operating temperature range: -55°C ~ 125°C
• Package designation: 01005 (0402 Metric)
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Thickness (Max): 0.009" (0.22mm)
• Mounting type: Surface Mount, MLCC
• Moisture sensitivity level: 1 (Unlimited)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

All identified substitute parts meet these parameters without exception. The substitutes are sourced from KYOCERA AVX, an alternative manufacturer, and are available in equivalent packaging (Tape & Reel). Substitution is valid for direct component replacement in circuit designs where the MSAST042SCG050CWNA01 is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MSAST042SCG050CWNA01, KGM02ACG1E5R0CH, and KGU02ACG1E5R0CH—are active production components with identical electrical specifications and mechanical compatibility. Selection between these parts is based on the following engineering considerations:

Compliance and Regulatory Status: All parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Supply Chain and Availability: The MSAST042SCG050CWNA01 (Taiyo Yuden) and KGM02ACG1E5R0CH (KYOCERA AVX) are suitable for general purpose applications. The KGU02ACG1E5R0CH (KYOCERA AVX) is specified for RF, microwave, and high frequency applications due to documented high Q and low loss characteristics, though all three parts meet the same electrical parameters.

Inventory Considerations: Component selection may be influenced by current stock levels and procurement lead times. The KGU02ACG1E5R0CH maintains the highest inventory availability at 20,761 pieces, followed by KGM02ACG1E5R0CH at 5,324 pieces, and MSAST042SCG050CWNA01 at 1,041 pieces.

Functional Equivalence: Direct substitution is valid across all three parts for applications requiring 5 pF capacitance at 25V with C0G/NP0 stability across -55°C to 125°C operating range in 01005 package format.

Frequently Asked Questions (FAQ)

Q: Can KGM02ACG1E5R0CH or KGU02ACG1E5R0CH be used as direct replacements for MSAST042SCG050CWNA01?

A: Yes. Both KYOCERA AVX parts are parametric equivalents with identical capacitance (5 pF), tolerance (±0.25pF), voltage rating (25V), temperature coefficient (C0G, NP0), operating temperature range (-55°C ~ 125°C), and package specifications (01005/0402 Metric). Direct substitution is valid without circuit modification.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching capacitance value, tolerance, voltage rating, temperature coefficient, operating temperature range, package type, physical dimensions, and moisture sensitivity level. All three parts meet these criteria identically.

Q: Are there differences in application suitability between the substitute parts?

A: The KGU02ACG1E5R0CH is specified for RF, microwave, and high frequency applications with documented high Q and low loss characteristics. The MSAST042SCG050CWNA01 and KGM02ACG1E5R0CH are designated for general purpose applications. However, all three parts meet identical electrical specifications and are mechanically compatible.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.

Q: Are regulatory and compliance certifications identical across all parts?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the physical compatibility of these parts in 01005 package format?

A: All three parts share identical physical dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm) with maximum thickness of 0.009" (0.22mm). They are mechanically interchangeable in 01005 (0402 Metric) footprints.

Q: Can these parts be used interchangeably in production assembly?

A: Yes. All parts are surface mount MLCCs in identical packaging (Tape & Reel) with matching footprint specifications, allowing interchangeable use in automated assembly processes without equipment or process modification.
