MSAST042SCG030AWNA01 Equivalent & Substitute Parts

Part Overview

The MSAST042SCG030AWNA01 is a 3 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V 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 is currently Active in product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified for applications requiring identical electrical and mechanical specifications, particularly when the primary part becomes unavailable or when alternative packaging formats are required.

Substitute Part Grouping Explanation

Substitute parts for the MSAST042SCG030AWNA01 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match Exactly):

• Capacitance: 3 pF
• Tolerance: ±0.05pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 01005 (0402 Metric)
• Physical Dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Thickness (Max): 0.009" (0.22mm)
• Mounting Type: Surface Mount, MLCC

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape) and product status (Active versus Not For New Designs), provided all electrical, mechanical, and compliance parameters remain identical. Manufacturer differences are acceptable when all specified parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MSAST042SCG030AWNA01): The MSAST042SCG030AWNA01 is the recommended choice for new designs. This part carries Active product status, indicating full manufacturer support and continued availability. It is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly operations. Current inventory of 825 pieces supports immediate procurement.

Secondary Selection (CQ0100ARNPO8BN3R0): The CQ0100ARNPO8BN3R0 manufactured by YAGEO is a fully qualified substitute with Active product status. All electrical, mechanical, and compliance parameters are identical to the primary part. This part is supplied in Tape & Reel (TR) packaging and maintains ROHS3 compliance. Inventory availability is significantly higher at 20,653 pieces, supporting high-volume production requirements. The CQ series is noted for High Q characteristics.

Tertiary Selection (TMK042CG030AD-W): The TMK042CG030AD-W is a Taiyo Yuden part with identical electrical and mechanical specifications. However, this part carries Not For New Designs product status, indicating it is in end-of-life phase. This part is supplied in Cut Tape (CT) packaging rather than Tape & Reel format, which may require alternative handling for automated assembly. Use of this part is limited to legacy system maintenance or when specific design constraints require Taiyo Yuden sourcing exclusively.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG030AD-W be used in new product designs? A: The TMK042CG030AD-W carries Not For New Designs product status. While electrically and mechanically equivalent, this designation indicates the manufacturer is discontinuing the part. New designs should utilize MSAST042SCG030AWNA01 or CQ0100ARNPO8BN3R0.

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. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically used for manual assembly or lower-volume applications. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Are all three parts suitable for automated assembly? A: MSAST042SCG030AWNA01 and CQ0100ARNPO8BN3R0 are supplied in Tape & Reel format, which is standard for automated assembly. TMK042CG030AD-W is supplied in Cut Tape format, which requires alternative handling procedures for automated systems.

Q: Do all substitute parts meet the same compliance requirements? A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Compliance certifications are identical across all qualified substitutes.

Q: What is the significance of C0G/NP0 temperature coefficient? A: C0G (Ceramic 0 ppm/°C) and NP0 (Negative-Positive 0 ppm/°C) designations indicate negligible capacitance change across the operating temperature range of -55°C to 125°C. This characteristic is essential for precision applications requiring stable capacitance values independent of temperature variations.

Q: Can I substitute parts from different manufacturers? A: Yes. CQ0100ARNPO8BN3R0 (YAGEO) is a fully qualified substitute for MSAST042SCG030AWNA01 (Taiyo Yuden). All electrical, mechanical, and compliance parameters are identical. Manufacturer selection may be based on availability, cost, or supply chain requirements.

Q: What inventory considerations should guide part selection? A: CQ0100ARNPO8BN3R0 offers significantly higher inventory availability (20,653 pieces) compared to MSAST042SCG030AWNA01 (825 pieces). For high-volume production, the YAGEO part may provide superior supply chain reliability. For immediate, limited-quantity requirements, either part supports procurement.
