Key Parameters

Substitute Part Grouping Explanation

Substitution of the MLAST042SCG040CWNA01 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters:

• Capacitance value: 4 pF
• Tolerance: ±0.25pF
• Rated voltage: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 01005 (0402 Metric)
• Mounting type: 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
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Substitute parts must maintain identical electrical performance, physical footprint compatibility, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the MLAST042SCG040CWNA01 (Taiyo Yuden) and KGM02ACG1E4R0CH (KYOCERA AVX) are Active product status components with full ROHS3 compliance and REACH unaffected status. Both parts are rated for identical electrical specifications (4 pF, ±0.25pF, 25V, C0G/NP0) and share identical mechanical packaging (01005/0402 Metric). Both components feature MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture handling requirements during storage or assembly.

The KGM02ACG1E4R0CH substitute part is available in higher inventory quantity (5219 Pcs) compared to the primary part (904 Pcs), providing enhanced supply chain availability. Selection between these parts should be based on procurement lead time, inventory availability, and established supplier relationships, as both parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the KGM02ACG1E4R0CH be used as a direct replacement for the MLAST042SCG040CWNA01?
