MLAST042SCG090CWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG090CWNA01 is a 9 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is packaged in 01005 (0402 Metric) form factor and is designed for applications requiring stable capacitance across temperature variations. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent substitute parts are necessary to address supply chain continuity, inventory availability, or procurement preferences while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution of the MLAST042SCG090CWNA01 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts must satisfy the following criteria:

Electrical Parameters:

• Capacitance value: 9 pF (exact match)
• Tolerance: ±0.25pF (exact match)
• Voltage rating: 25V (exact match or higher)
• Temperature coefficient: C0G/NP0 (exact match for temperature stability)
• Operating temperature range: -55°C ~ 125°C (exact match)

Mechanical Parameters:

• Package type: 01005 (0402 Metric) (exact match)
• Mounting type: Surface Mount, MLCC (exact match)
• Physical dimensions: 0.016" L x 0.008" W / 0.40mm x 0.20mm (exact match)
• Maximum thickness: 0.009" (0.22mm) (exact match)
• Packaging format: Tape & Reel (TR) (exact match)

Compliance Parameters:

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

The identified substitute parts KGM02ACG1E9R0CH and KGU02ACG1E9R0CH from KYOCERA AVX meet all specified electrical, mechanical, and compliance requirements and are therefore direct parametric equivalents.
