Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLASE042SCG910JWNA01 is determined by strict equivalence across the following parameters:

Electrical Parameters:

• Capacitance value: 91 pF
• Tolerance: ±5%
• Voltage rating: 16V (minimum)
• Temperature coefficient: C0G or NP0 designation
• Operating temperature range: -55°C to 125°C

Mechanical Parameters:

• Package code: 01005 (0402 Metric)
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Maximum thickness: 0.009" (0.22mm)
• Mounting type: Surface Mount, MLCC

Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts match these parameters exactly. Substitution does not require design modification, PCB layout changes, or requalification of assembly processes.

Engineering Selection Recommendations

Primary Selection: MLASE042SCG910JWNA01

The MLASE042SCG910JWNA01 is the recommended primary choice for new designs and ongoing production. This part carries Active product status, indicating full manufacturer support, continued availability, and compliance with current industry standards. It is suitable for medical and non-critical applications with ROHS3 compliance and unlimited moisture sensitivity rating.

Secondary Selection: EMK042CG910JC-W

The EMK042CG910JC-W is a parametric equivalent from Taiyo Yuden with identical electrical and mechanical specifications. This part is marked as Not For New Designs, indicating the manufacturer has transitioned focus to newer product lines. However, it remains electrically and mechanically interchangeable with the primary part. This substitute is appropriate for legacy system maintenance, field repairs, or applications where existing inventory must be utilized. Inventory availability is significantly higher at 80,716 pieces.

Tertiary Selection: C0402C0G1C910J

The C0402C0G1C910J is manufactured by TDK Corporation and provides full parametric equivalence across all electrical, mechanical, and compliance specifications. This part is designated as Obsolete, indicating it is no longer manufactured or supported by TDK. Selection of this part is limited to situations where existing inventory must be consumed or when no other alternatives are available. Inventory is available at 14,245 pieces. Packaging differs from the primary part (Cut Tape and Digi-Reel versus Tape & Reel), which may affect assembly line compatibility.

Selection Criteria Summary:

• For new designs and active production: MLASE042SCG910JWNA01
• For high-volume requirements with extended lead times: EMK042CG910JC-W
• For legacy system support only: C0402C0G1C910J

Frequently Asked Questions (FAQ)

Q: Can the EMK042CG910JC-W be used as a direct replacement for the MLASE042SCG910JWNA01?

A: Yes. The EMK042CG910JC-W is a parametric equivalent with identical capacitance (91 pF), tolerance (±5%), voltage rating (16V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), package dimensions (01005/0402 Metric), and compliance certifications (ROHS3, REACH Unaffected, MSL 1). No circuit modifications, PCB layout changes, or requalification are required for direct substitution.

Q: Why is the C0402C0G1C910J marked as Obsolete?

A: Obsolete status indicates that TDK Corporation has discontinued manufacturing of this part number. While existing inventory may be available through distribution channels, the manufacturer no longer produces or supports this component. New designs should not incorporate obsolete parts due to long-term supply uncertainty.

Q: What is the difference between the packaging types listed for these parts?

A: The MLASE042SCG910JWNA01 and EMK042CG910JC-W are supplied in Tape & Reel (TR) format, which is standard for automated assembly line pick-and-place equipment. The C0402C0G1C910J is supplied in Cut Tape (CT) and Digi-Reel® format, which may require different handling and feeding mechanisms on assembly equipment. Physical component dimensions and electrical performance are identical; packaging format affects logistics and assembly process compatibility only.

Q: Are all three parts suitable for medical applications?

A: The MLASE042SCG910JWNA01 is explicitly rated for medical and non-critical applications. The EMK042CG910JC-W is rated for general purpose applications. The C0402C0G1C910J is rated for general purpose applications. Medical application suitability depends on specific regulatory requirements and qualification standards. Confirm application requirements with design and quality assurance teams before selecting EMK042CG910JC-W or C0402C0G1C910J for medical use.

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

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has the lowest moisture sensitivity classification. These parts do not require special moisture-controlled storage conditions, desiccant packaging, or bake-out procedures prior to assembly. Standard warehouse storage conditions are acceptable.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided that the assembly process equipment is compatible with the packaging format. All three parts have identical electrical performance, mechanical dimensions, and compliance certifications. If the assembly line is configured for Tape & Reel format, either MLASE042SCG910JWNA01 or EMK042CG910JC-W can be used. If the assembly line accepts Cut Tape format, C0402C0G1C910J is compatible. Physical component performance is identical regardless of packaging format.

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

A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic. This classification indicates that capacitance change over the operating temperature range (-55°C to 125°C) is minimal and predictable. C0G/NP0 capacitors are suitable for precision timing circuits, filters, and applications where stable capacitance is required across temperature variations.
