MLASE042SCG3R9CWNA01 Equivalent & Substitute Parts

Part Overview

The MLASE042SCG3R9CWNA01 is a 3.9 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 16V operation with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is packaged in the 01005 (0402 Metric) form factor and is classified as Active product status. Substitute parts are identified for applications requiring equivalent electrical and mechanical specifications, particularly when primary inventory availability is limited or when alternative manufacturer sourcing is necessary.

Substitute Part Grouping Explanation

Substitute parts for the MLASE042SCG3R9CWNA01 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 3.9 pF
• Tolerance: ±0.25pF
• Voltage rating: 16V minimum
• Temperature coefficient: C0G or NP0 designation
• Operating temperature range: -55°C to 125°C

Mechanical Equivalence Criteria:

• 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 Equivalence Criteria:

• RoHS3 compliance
• REACH unaffected status
• Moisture Sensitivity Level 1

Parts meeting all three criteria categories are classified as parametric equivalents and direct substitutes.

Engineering Selection Recommendations

MLASE042SCG3R9CWNA01 (Taiyo Yuden) - Primary Selection

The MLASE042SCG3R9CWNA01 maintains Active product status with 1023 units in current inventory. This part is suitable for applications requiring medical-grade or non-critical component specifications. Taiyo Yuden manufacturing ensures consistent quality and long-term availability support.

C0402C0G1C3R9C (TDK Corporation) - Secondary Selection

The C0402C0G1C3R9C is a direct parametric equivalent with 17344 units available. However, this part carries Obsolete product status, indicating discontinued manufacturing. Selection of this substitute should be limited to applications where existing inventory can support long-term supply requirements without future replenishment. TDK Corporation maintains full ROHS3 and REACH compliance.

CC0100CRNPO7BN3R9 (YAGEO) - Preferred Alternative

The CC0100CRNPO7BN3R9 is a direct parametric equivalent with 101072 units in inventory and Active product status. YAGEO maintains ongoing production and supply chain support. This part is suitable for general purpose applications and provides the highest inventory availability among all qualified substitutes. Full ROHS3 and REACH compliance is maintained.

Frequently Asked Questions (FAQ)

Q: Can C0402C0G1C3R9C be used as a direct replacement for MLASE042SCG3R9CWNA01?

A: Yes, the C0402C0G1C3R9C meets all electrical and mechanical equivalence criteria. However, the Obsolete product status indicates TDK has discontinued manufacturing. Use this substitute only when existing inventory is available and future replenishment is not required.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 designations are equivalent specifications for the same temperature coefficient characteristic. Both terms describe zero temperature coefficient behavior across the operating range of -55°C to 125°C.

Q: Are all three substitute parts suitable for medical applications?

A: The MLASE042SCG3R9CWNA01 is specified for medical and non-critical applications. The substitute parts C0402C0G1C3R9C and CC0100CRNPO7BN3R9 are specified for general purpose applications. Medical application suitability must be confirmed through application-specific qualification procedures.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. The component can be stored and handled without special moisture control procedures.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, all three parts share identical package dimensions (01005/0402 Metric), mounting type (Surface Mount, MLCC), and footprint requirements. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is the significance of ROHS3 compliance?

A: ROHS3 compliance certifies that the component meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All three parts maintain this compliance.

Q: Why does CC0100CRNPO7BN3R9 have higher inventory than the primary part?

A: YAGEO maintains active production status with higher manufacturing volume allocation. The CC0100CRNPO7BN3R9 represents a high-volume alternative suitable for applications with extended supply requirements.
