MLAST042SCG030BWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG030BWNA01 is a 3 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 the 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 rating (MSL 1). Equivalent substitute parts are necessary to address supply chain continuity, inventory availability, or procurement preferences while maintaining identical electrical and mechanical performance.

• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C ~ 125°C

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)

Compliance Parameters (Must Match or Exceed):

• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

All substitute parts listed below meet these criteria and are classified as parametric equivalents suitable for direct replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—MLAST042SCG030BWNA01 (Taiyo Yuden), CQ0100BRNPO8BN3R0 (YAGEO), and KGM02ACG1E3R0BH (KYOCERA AVX)—are active production components with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Compliance Considerations: The MLAST042SCG030BWNA01 and KGM02ACG1E3R0BH both carry explicit ROHS3 compliance certification. The CQ0100BRNPO8BN3R0 does not specify RoHS status in the provided data; verification of compliance status is necessary if ROHS3 certification is a procurement requirement.

Availability and Inventory: Current stock levels vary: YAGEO CQ0100BRNPO8BN3R0 (20,710 pcs), KYOCERA AVX KGM02ACG1E3R0BH (5,373 pcs), and Taiyo Yuden MLAST042SCG030BWNA01 (1,028 pcs). Selection may be influenced by supply chain requirements and lead time considerations.

Product Status: All three parts maintain active production status, ensuring long-term availability and consistent manufacturing quality.

Regulatory and Environmental: All parts are REACH Unaffected and carry EAR99 ECCN classification. HTSUS code 8532.24.0020 applies uniformly across all three parts.

Frequently Asked Questions (FAQ)

Q: Can the CQ0100BRNPO8BN3R0 (YAGEO) be used as a direct replacement for the MLAST042SCG030BWNA01 (Taiyo Yuden)?

A: Yes. Both parts are parametric equivalents with identical capacitance (3 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (01005/0402 Metric), and physical dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the significance of the C0G/NP0 temperature coefficient designation?

A: C0G (also designated NP0) indicates a temperature coefficient of 0 ppm/°C, meaning capacitance remains stable across the operating temperature range of -55°C to 125°C. This specification is critical for applications requiring predictable capacitance performance across temperature variations and must match exactly for substitution.

Q: Are all substitute parts suitable for medical applications?

A: The MLAST042SCG030BWNA01 is specified for medical and non-critical applications. The YAGEO CQ0100BRNPO8BN3R0 and KYOCERA AVX KGM02ACG1E3R0BH are specified for general purpose applications. Application suitability should be confirmed against specific medical device requirements and regulatory standards.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component can be stored indefinitely without special moisture control measures. All three parts carry this rating, ensuring identical handling and storage requirements.

Q: Is the 01005 (0402 Metric) package size compatible with standard PCB assembly equipment?

A: Yes. The 01005 package is a standard surface-mount form factor compatible with modern pick-and-place assembly equipment. All three parts use identical dimensions (0.016" L x 0.008" W / 0.40mm x 0.20mm) and maximum thickness (0.009" / 0.22mm), ensuring mechanical compatibility with existing assembly processes.

Q: What is the difference between the MLAST042SCG030BWNA01 and KGM02ACG1E3R0BH in terms of compliance?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and identical HTSUS code 8532.24.0020. Compliance profiles are equivalent.

Q: Can these parts be used interchangeably in high-frequency RF circuits?

A: All three parts are specified with identical electrical parameters (3 pF, ±0.1pF, C0G/NP0). High-frequency performance depends on additional factors not provided in the parametric data, such as equivalent series resistance (ESR), quality factor (Q), and frequency response characteristics. The YAGEO CQ0100BRNPO8BN3R0 is noted to have High Q characteristics; however, detailed frequency response data is not provided for comparison.

Q: What is the lead spacing and lead style for these components?

A: Lead spacing and lead style information is not provided in the parametric data for any of the three parts. These components are surface-mount MLCCs with no discrete leads; they are soldered directly to PCB pads.
