MSAST042SCG2R7AWNA01 Equivalent & Substitute Parts

Part Overview

The MSAST042SCG2R7AWNA01 is a 2.7 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 designed for general purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C.

The main part is currently in Active product status with 621 pieces available in inventory. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate alternative manufacturers or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MSAST042SCG2R7AWNA01 are identified based on strict parametric equivalence. All substitute parts must satisfy the following mandatory criteria:

Critical Matching Parameters:

• Capacitance: 2.7 pF (exact match)
• Tolerance: ±0.05pF (exact match)
• Voltage Rating: 25V (minimum requirement)
• Temperature Coefficient: C0G/NP0 (exact match)
• Package / Case: 01005 (0402 Metric) (exact match)
• Mounting Type: Surface Mount, MLCC (exact match)
• Operating Temperature Range: -55°C ~ 125°C (exact match)

Compliance Parameters:

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)

Substitutes may differ in the following non-critical parameters:

• Manufacturer identity
• Packaging format (Tape & Reel vs. Cut Tape)
• Product status (Active vs. Not For New Designs)
• Inventory availability
• Series designation
• Optional features (e.g., High Q rating)

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MSAST042SCG2R7AWNA01): The original part maintains Active product status and is the preferred choice for new designs. It is supplied in Tape & Reel packaging format, which is standard for automated assembly operations. RoHS3 compliance and MSL 1 rating confirm suitability for standard manufacturing environments.

Secondary Selection (CQ0100ARNPO8BN2R7): This YAGEO equivalent is recommended as the primary substitute due to its Active product status and significantly higher inventory availability (20447 pieces). All critical electrical and mechanical parameters match the original part exactly. The High Q feature provides additional performance margin in applications requiring low loss characteristics. Tape & Reel packaging maintains compatibility with standard assembly processes.

Tertiary Selection (TMK042CG2R7AD-W): This Taiyo Yuden equivalent is electrically and mechanically identical to the original part but carries a Not For New Designs product status. It is supplied in Cut Tape format, which may require alternative handling procedures compared to Tape & Reel packaging. This part is suitable only for replacement or repair of existing assemblies where the original part is unavailable.

Compliance Verification: All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, confirming compatibility with standard PCB assembly, storage, and handling procedures without special environmental controls.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG2R7AD-W be used in new product designs? A: No. TMK042CG2R7AD-W carries a Not For New Designs product status and is restricted to replacement or repair applications only. For new designs, use MSAST042SCG2R7AWNA01 or CQ0100ARNPO8BN2R7.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape supplies components on cut segments of carrier tape, typically used for manual assembly or lower-volume production. Both formats contain identical components.

Q: Are all three parts electrically interchangeable? A: Yes. All three parts have identical capacitance (2.7 pF), tolerance (±0.05pF), voltage rating (25V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 125°C). They are direct electrical equivalents.

Q: Does the High Q feature of CQ0100ARNPO8BN2R7 affect compatibility? A: No. High Q is an additional performance characteristic that reduces dielectric loss. It does not affect electrical compatibility or circuit operation. The part remains a direct substitute.

Q: Are there any differences in physical dimensions between the three parts? A: No. All three 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).

Q: What is the significance of MSL 1 (Unlimited) rating? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Standard warehouse conditions are acceptable.

Q: Can I mix parts from different manufacturers in the same assembly? A: Yes. All three parts meet identical electrical and mechanical specifications. Mixing manufacturers within a single assembly does not affect circuit performance or reliability.

Q: Which part should I select for highest inventory availability? A: CQ0100ARNPO8BN2R7 offers the highest inventory availability at 20447 pieces, compared to 621 pieces for MSAST042SCG2R7AWNA01 and 999 pieces for TMK042CG2R7AD-W.
