MSART042SCG3R8BWRA01 Equivalent & Substitute Parts
Part Overview
The MSART042SCG3R8BWRA01 is a 3.8 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V operation with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is packaged in 01005 (0402 Metric) form factor and is supplied in Tape & Reel (TR) packaging. The part maintains Active product status and is ROHS3 compliant with MSL 1 moisture sensitivity rating.
Substitute parts become necessary when Tape & Reel packaging is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits equivalent electrical performance from alternative packaging formats. The identified substitute maintains identical electrical specifications and mechanical dimensions while offering different packaging and availability characteristics.

Substitute Part Grouping Explanation
Substitution logic for the MSART042SCG3R8BWRA01 is based on strict electrical and mechanical parameter matching. The primary substitute, TMK042CG3R8BD-W, qualifies as an equivalent part because it maintains identical specifications across all critical parameters:
Electrical Parameters (Must Match):
- Capacitance: 3.8 pF
- Tolerance: ±0.1pF
- Voltage Rating: 25V
- Temperature Coefficient: C0G, NP0
- Operating Temperature Range: -55°C ~ 125°C
Mechanical Parameters (Must Match):
- Package / Case: 01005 (0402 Metric)
- Physical Dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
- Thickness: 0.009" (0.22mm) maximum
- Mounting Type: Surface Mount, MLCC
Compliance Parameters (Must Match or Exceed):
- RoHS Status: ROHS3 Compliant
- MSL Rating: 1 (Unlimited)
The substitute differs only in packaging format (Cut Tape versus Tape & Reel) and product status designation, neither of which affects electrical or mechanical compatibility in the circuit application.

Engineering Selection Recommendations
Primary Selection (MSART042SCG3R8BWRA01): The main part is recommended for new designs and production applications. It maintains Active product status, indicating ongoing manufacturer support and availability. Tape & Reel packaging is optimized for automated assembly processes and high-volume manufacturing environments.
Substitute Selection (TMK042CG3R8BD-W): The substitute part is electrically and mechanically equivalent and is suitable for applications where Cut Tape packaging is acceptable or preferred. However, the "Not For New Designs" status indicates this part is in mature or declining production phase. This part is appropriate for:
- Replacement or repair of existing assemblies
- Low-volume or prototype applications where Cut Tape packaging is compatible with assembly processes
- Situations where inventory availability of the main part is constrained
Both parts maintain identical ROHS3 compliance and MSL 1 ratings, ensuring regulatory and environmental handling requirements are equivalent.
Frequently Asked Questions (FAQ)
Q: Can TMK042CG3R8BD-W be used as a direct replacement for MSART042SCG3R8BWRA01 in production?
A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (3.8 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), and physical dimensions (01005/0402 Metric). The difference is packaging format (Cut Tape versus Tape & Reel). Production compatibility depends on whether your assembly equipment can process Cut Tape format. The substitute's "Not For New Designs" status means it may have limited long-term availability.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments, typically used for lower-volume assembly, manual placement, or equipment with different tape handling specifications. Both formats contain the same component; the difference is in supply format and handling method.
Q: Are there any electrical performance differences between these parts?
A: No. Both parts are manufactured by Taiyo Yuden and share identical electrical specifications: 3.8 pF capacitance, ±0.1pF tolerance, 25V rating, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range. They are functionally equivalent in circuit applications.
Q: What does "Not For New Designs" mean for the substitute part?
A: This status indicates the manufacturer is not actively promoting the part for new product designs. It may have reduced production priority, limited availability, or planned discontinuation. For new designs, the Active status part (MSART042SCG3R8BWRA01) is the preferred choice. The substitute is suitable for maintenance, repair, or prototype applications where long-term availability is not critical.
Q: Do both parts have the same moisture sensitivity rating?
A: Yes. Both parts have MSL 1 (Unlimited) rating, meaning they have unlimited shelf life under normal storage conditions and do not require special moisture control during handling or storage.
Q: Are both parts RoHS compliant?
A: Yes. Both parts are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions in electronic components.
