MSART042SCG1R4AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG1R4AWRA01 is a 1.4 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 is currently in Active product status with 788 pieces available in stock.

Substitute parts become necessary when Tape & Reel packaging is unavailable, when alternative product lifecycle statuses are acceptable for specific applications, or when alternative packaging formats (Cut Tape) meet procurement requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MSART042SCG1R4AWRA01 is permissible only when the following conditions are met:

Mandatory Matching Parameters:

• Capacitance: 1.4 pF (exact match required)
• Tolerance: ±0.05pF (exact match required)
• Voltage Rating: 25V (exact match required)
• Temperature Coefficient: C0G, NP0 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Package / Case: 01005 (0402 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Variable Parameters Permitting Substitution:

• Packaging Format: Tape & Reel (TR) may be substituted with Cut Tape (CT) or other standard packaging formats
• Product Status: Active status parts may be substituted with Not For New Designs status parts when lifecycle requirements permit
• Manufacturer Series designation: MSAR series may be substituted with M series or other Taiyo Yuden series maintaining identical electrical specifications

The substitute part TMK042CG1R4AD-W meets all mandatory matching parameters and differs only in packaging format (Cut Tape versus Tape & Reel) and product lifecycle status (Not For New Designs versus Active).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MSART042SCG1R4AWRA01): Select the MSART042SCG1R4AWRA01 for new design implementations. This part carries Active product status, indicating full manufacturer support and continued availability. The Tape & Reel packaging format is optimized for automated assembly processes and high-volume production environments.

Substitute Selection (TMK042CG1R4AD-W): The TMK042CG1R4AD-W is electrically and mechanically equivalent to the primary part. This substitute is appropriate when:

• Tape & Reel packaging is unavailable or procurement constraints require Cut Tape format
• Existing inventory of the substitute part is available and cost-effective
• Application requirements do not mandate Active product status designation

The substitute part carries Not For New Designs status, indicating the manufacturer is transitioning away from this product line. Use of this part in new designs should be evaluated against long-term supply chain requirements and product lifecycle planning.

Both parts maintain identical ROHS3 compliance, EAR99 export classification, and HTSUS commodity code designation, ensuring regulatory and trade compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG1R4AD-W be used as a direct replacement for MSART042SCG1R4AWRA01 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical. The TMK042CG1R4AD-W will function identically in any circuit designed for the MSART042SCG1R4AWRA01. The only differences are packaging format (Cut Tape versus Tape & Reel) and product lifecycle status.

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, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically used for lower-volume assembly or manual handling. Both formats contain identical components with identical electrical specifications.

Q: Why is the substitute part marked "Not For New Designs"?

A: This designation indicates the manufacturer is discontinuing or has discontinued this product line. The part remains available and functional but is not recommended for new product development. Existing inventory may be used for replacement, repair, or legacy product support.

Q: Are there any performance differences between the main part and substitute?

A: No. All electrical parameters, mechanical dimensions, temperature characteristics, and regulatory compliance specifications are identical. Performance in circuit operation is equivalent.

Q: Can I mix Tape & Reel and Cut Tape packaging in the same production run?

A: Yes, provided your assembly equipment can accommodate both packaging formats. The components themselves are identical; only the delivery format differs. Verify your assembly process can handle both tape formats without requiring equipment reconfiguration.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life under normal storage conditions. No special moisture-control storage (dry boxes or desiccant) is required. The component can be stored and handled under standard industrial conditions without moisture-related degradation.

Q: Are both parts RoHS compliant?

A: Yes. Both MSART042SCG1R4AWRA01 and TMK042CG1R4AD-W are ROHS3 compliant, meeting all current lead-free and hazardous substance restrictions for electronic components.
