Substitute Part Grouping Explanation

Substitute parts for the MSAST042SCG3R9CWNA01 are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Capacitance value: 3.9 pF
• Tolerance: ±0.25 pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters (Must Match Exactly):

• Package / Case: 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)
• Packaging format: Tape & Reel (TR)

Environmental & Compliance Parameters (Must Match):

• Operating temperature range: -55°C to 125°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

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

Parameter Comparison

Engineering Selection Recommendations

The CC0100CRNPO8BN3R9 (YAGEO) is a direct parametric equivalent to the MSAST042SCG3R9CWNA01 (Taiyo Yuden). Both parts are active production items with identical electrical specifications, mechanical dimensions, and environmental compliance ratings.

Selection Basis:
