Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSAST042SCG100DWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 10 pF
• Tolerance: ±0.5pF
• Rated voltage: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 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)

The substitute part TMK042CG100DD-W meets all electrical, mechanical, and compliance requirements. The primary difference between the main part and substitute is the packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. Both formats are compatible with standard surface mount assembly equipment.

Engineering Selection Recommendations

MSAST042SCG100DWNA01 (Primary Selection)

The MSAST042SCG100DWNA01 is the recommended selection for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. It is supplied in Tape & Reel (TR) packaging, which is optimized for high-volume automated assembly operations. Current inventory of 779 pieces supports immediate procurement requirements.

TMK042CG100DD-W (Substitute Selection)

The TMK042CG100DD-W is a parametric equivalent suitable for applications where Cut Tape (CT) packaging is acceptable or preferred. This part is designated as Not For New Designs by the manufacturer, indicating it is maintained for legacy support and existing design continuity only. The substitute maintains full electrical and mechanical equivalence with identical capacitance, voltage rating, temperature coefficient, and physical dimensions. Inventory availability is significantly higher at 62,732 pieces.

Both parts satisfy identical compliance requirements: ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. Selection between these parts should be based on packaging format requirements and design lifecycle stage.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG100DD-W be used as a direct replacement for MSAST042SCG100DWNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel (TR) versus Cut Tape (CT). Both formats are compatible with standard surface mount assembly equipment. Verify that your assembly process can accommodate the Cut Tape format if substituting.

Q: What is the significance of the "Not For New Designs" status on the TMK042CG100DD-W?

A: This designation indicates the manufacturer is not recommending this part for new product development. However, it remains available for legacy support and existing design continuity. For new designs, the MSAST042SCG100DWNA01 (Active status) is the appropriate selection.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in 01005 (0402 Metric) form factor with identical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum thickness of 0.009" (0.22mm). They are mechanically interchangeable on the PCB.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. They satisfy identical regulatory and environmental requirements.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel, optimized for high-volume automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, typically used for lower-volume assembly or manual handling. Both are compatible with standard surface mount assembly processes.

Q: Are the electrical specifications identical?

A: Yes. Both parts have identical capacitance (10 pF), tolerance (±0.5pF), rated voltage (25V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 125°C).
