Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MSAST042SCG090CWNA01 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters:

• Capacitance value: 9 pF
• Tolerance: ±0.25 pF
• Voltage rating: 25V minimum
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 01005 (0402 Metric)
• Mounting: Surface Mount, MLCC
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Maximum thickness: 0.009" (0.22mm)

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH status: REACH Unaffected

All identified substitute parts meet these criteria and are classified as parametric equivalents. The KGM02ACG1E9R0CH and KGU02ACG1E9R0CH from KYOCERA AVX maintain identical electrical specifications and package dimensions, enabling direct substitution in circuit designs.
