MSAST042SCG080CWNA01 Equivalent & Substitute Parts

Part Overview

The MSAST042SCG080CWNA01 is an 8 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 temperature variations. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts are necessary to address supply chain continuity, inventory availability, or design flexibility requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the MSAST042SCG080CWNA01 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Mandatory Matching Parameters:

• Capacitance value: 8 pF
• Capacitance tolerance: ±0.25pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 125°C
• Package type: 01005 (0402 Metric)
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Thickness: 0.009" (0.22mm) maximum
• Mounting type: Surface Mount, MLCC
• Moisture sensitivity level: 1 (Unlimited)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

All identified substitute parts meet these requirements and are manufactured by KYOCERA AVX, maintaining full parametric equivalence with the original Taiyo Yuden component.

Parameter Comparison

Engineering Selection Recommendations

Both KYOCERA AVX substitute parts (KGM02ACG1E8R0CH and KGU02ACG1E8R0CH) are direct parametric equivalents to the MSAST042SCG080CWNA01. Selection between these options is based on product status and availability:

KGM02ACG1E8R0CH is designated for general-purpose applications and maintains identical specifications to the original part. This part carries active product status with 7,846 units in current inventory.

KGU02ACG1E8R0CH is designated for RF, microwave, and high-frequency applications with documented high Q and low-loss characteristics. This part carries active product status with 19,500 units in current inventory. The expanded application scope does not alter the core electrical or mechanical parameters and represents a superset of the original part's capabilities.

All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across manufacturing environments. The choice between substitutes depends on application requirements and supply chain considerations rather than electrical or mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can KGM02ACG1E8R0CH and KGU02ACG1E8R0CH be used interchangeably with MSAST042SCG080CWNA01?

A: Yes. Both KYOCERA AVX parts meet all mandatory electrical and mechanical parameters: 8 pF capacitance, ±0.25pF tolerance, 25V rating, C0G/NP0 temperature coefficient, -55°C to 125°C operating range, and 01005 (0402 Metric) package dimensions. Physical footprint and mounting characteristics are identical.

Q: What is the difference between KGM02ACG1E8R0CH and KGU02ACG1E8R0CH?

A: Both parts are parametrically identical in capacitance, voltage, tolerance, temperature coefficient, and package specifications. KGU02ACG1E8R0CH is specified for RF, microwave, and high-frequency applications with high Q and low-loss characteristics. For general-purpose applications, either part is suitable.

Q: Are there any compliance or regulatory differences between the three parts?

A: No. All three parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (Unlimited) for all parts, and all use identical HTSUS and ECCN classifications.

Q: Can these parts be used in high-frequency or RF circuits?

A: The KGU02ACG1E8R0CH is specifically rated for RF, microwave, and high-frequency applications. The MSAST042SCG080CWNA01 and KGM02ACG1E8R0CH are specified for general-purpose applications. Application suitability depends on circuit requirements beyond the parametric specifications provided.

Q: What is the physical footprint compatibility?

A: All three parts use the 01005 (0402 Metric) package with identical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm) and 0.009" (0.22mm) maximum thickness. PCB layout and assembly processes require no modification.

Q: Are there inventory considerations for part selection?

A: Current inventory levels are: MSAST042SCG080CWNA01 (686 units), KGM02ACG1E8R0CH (7,846 units), and KGU02ACG1E8R0CH (19,500 units). Availability may influence procurement decisions based on project timelines.
