Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MLAST042SCG1R2CWNA01 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must match identically:

• Capacitance Value: 1.2 pF
• Capacitance Tolerance: ±0.25pF
• Rated Voltage: 25V
• Temperature Coefficient: C0G/NP0
• Operating Temperature Range: -55°C ~ 125°C
• Package / Case: 01005 (0402 Metric)
• Physical Dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Maximum Thickness: 0.009" (0.22mm)
• Mounting Type: Surface Mount, MLCC
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Manufacturer differences do not affect substitution eligibility when all electrical and mechanical parameters are identical.
