Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG0R4AWRA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.4 pF
• Capacitance tolerance: ±0.05pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• 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)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 125°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS3 compliance

All identified substitute parts meet these criteria. Packaging configuration (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility and represents a procurement variable only.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: MSART042SCG0R4AWRA01

The MSART042SCG0R4AWRA01 is the recommended choice for new designs. This part carries Active product status, indicating ongoing manufacturer support and long-term availability. It is ROHS3 compliant and packaged in Tape & Reel configuration, suitable for automated assembly processes. Current inventory of 1016 units supports immediate procurement.

Secondary Selection: CQ0100ARNPO8BNR40

The CQ0100ARNPO8BNR40 from YAGEO is an active product with the highest inventory availability (12355 units). This part meets all electrical and mechanical specifications and is packaged in Tape & Reel format. Selection of this substitute is appropriate when primary manufacturer availability is constrained or when supply chain diversification is required.

Tertiary Selection: TMK042CG0R4AD-W

The TMK042CG0R4AD-W is a Taiyo Yuden product with equivalent electrical specifications but carries "Not For New Designs" status. This part is available in Cut Tape packaging and should be selected only for legacy design support or when existing inventory must be utilized. The Cut Tape configuration may require manual handling during assembly.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG0R4AD-W be used as a direct replacement for MSART042SCG0R4AWRA01?

A: Yes, from an electrical and mechanical standpoint, TMK042CG0R4AD-W is a direct equivalent. Both parts share identical capacitance (0.4 pF), tolerance (±0.05pF), voltage rating (25V), temperature coefficient (C0G/NP0), package type (01005), and operating temperature range (-55°C to 125°C). The primary difference is product status (Not For New Designs) and packaging configuration (Cut Tape versus Tape & Reel). For new designs, MSART042SCG0R4AWRA01 is preferred.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically requiring manual handling or semi-automated processing. Both configurations contain identical components; the difference is in supply format and assembly process compatibility.

Q: Are all three substitute parts compatible with the same PCB layout and assembly process?

A: All three parts share identical physical dimensions (0.016" L x 0.008" W, 0.40mm x 0.20mm) and maximum thickness (0.009" / 0.22mm), ensuring PCB layout compatibility. Assembly process compatibility depends on packaging configuration: MSART042SCG0R4AWRA01 and CQ0100ARNPO8BNR40 (both Tape & Reel) are compatible with automated assembly; TMK042CG0R4AD-W (Cut Tape) requires manual or semi-automated handling.

Q: What does "Not For New Designs" status mean for TMK042CG0R4AD-W?

A: "Not For New Designs" indicates that the manufacturer (Taiyo Yuden) is not recommending this part for incorporation into new product designs. This status typically reflects product lifecycle management and does not indicate a defect or performance issue. Existing inventory may be used for legacy product support or maintenance applications.

Q: Is RoHS3 compliance verified for all substitute parts?

A: ROHS3 compliance is explicitly confirmed for MSART042SCG0R4AWRA01 and TMK042CG0R4AD-W. RoHS status for CQ0100ARNPO8BNR40 is not specified in the provided data. Verification of RoHS compliance for the YAGEO part should be obtained from the manufacturer if regulatory compliance documentation is required.

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

A: Yes, all three parts are electrically and mechanically equivalent and can be used interchangeably in existing production runs. Selection should be based on current inventory availability, packaging requirements (Tape & Reel versus Cut Tape), and supply chain considerations. No circuit redesign or PCB modification is required when substituting between these parts.
