Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLAST042SCG2R7AWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 2.7 pF
• Tolerance: ±0.05pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 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

Environmental & Compliance Parameters:

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

Substitute parts identified in this reference maintain identical electrical performance and mechanical compatibility. Packaging format (Tape & Reel versus Cut Tape) and product status variations do not affect functional equivalence but may impact procurement and design lifecycle considerations.

Parameter Comparison

Engineering Selection Recommendations

MLAST042SCG2R7AWNA01 (Primary Part)

The MLAST042SCG2R7AWNA01 maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. This part is suitable for new designs and ongoing production applications. Tape & Reel packaging supports high-volume automated assembly operations.

TMK042CG2R7AD-W (Taiyo Yuden Alternative)

The TMK042CG2R7AD-W is electrically and mechanically equivalent to the main part but carries Not For New Designs product status. This part is suitable for legacy system maintenance, repair, and sustaining production of existing designs. Cut Tape packaging may require manual handling or alternative assembly processes. Both parts share Taiyo Yuden manufacturing heritage and identical electrical specifications.

CQ0100ARNPO8BN2R7 (YAGEO Alternative)

The CQ0100ARNPO8BN2R7 is manufactured by YAGEO and maintains Active product status with full ROHS3 compliance. This part provides cross-manufacturer equivalence with identical electrical and mechanical parameters. The CQ series designation indicates High Q characteristics. Tape & Reel packaging supports automated assembly workflows. This part offers supply chain diversification from an alternative qualified manufacturer.

Selection between these three parts depends on design phase requirements, supply chain strategy, and packaging format compatibility with assembly equipment. All three parts satisfy identical electrical performance and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG2R7AD-W be used as a direct replacement for MLAST042SCG2R7AWNA01 in new designs?

A: TMK042CG2R7AD-W carries Not For New Designs product status. While electrically and mechanically equivalent, design guidelines typically restrict new design implementations to Active status parts. For new designs, MLAST042SCG2R7AWNA01 or CQ0100ARNPO8BN2R7 are appropriate selections.

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 high-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically used for lower-volume manual or semi-automated assembly. Both formats contain identical components; packaging format selection depends on assembly equipment and production volume requirements.

Q: Are all three parts suitable for medical applications?

A: The MLAST042SCG2R7AWNA01 is specified for Medical and Non-Critical applications. The TMK042CG2R7AD-W is specified for General Purpose applications. The CQ0100ARNPO8BN2R7 is specified for General Purpose applications. Medical application suitability depends on specific regulatory requirements and design specifications beyond the parametric equivalence provided in this reference.

Q: Do these parts have identical temperature stability?

A: All three parts share identical C0G/NP0 temperature coefficient classification and operate across the same temperature range (-55°C ~ 125°C). C0G/NP0 designation ensures minimal capacitance variation across the operating temperature range, providing equivalent temperature stability across all three parts.

Q: What is the significance of High Q in the CQ0100ARNPO8BN2R7 specification?

A: High Q indicates lower dielectric loss characteristics in the CQ series ceramic capacitor. This feature may provide performance advantages in high-frequency or precision circuit applications. However, this specification does not affect parametric equivalence for basic capacitance, voltage, tolerance, or temperature coefficient requirements.

Q: Can these parts be intermixed in the same production run?

A: All three parts meet identical electrical and mechanical specifications for the 01005 package form factor. Intermixing is technically feasible from a functional standpoint. However, production control procedures, traceability requirements, and design documentation should govern part selection and substitution protocols within manufacturing operations.

Q: What is the inventory status for each part?

A: MLAST042SCG2R7AWNA01 has 1041 pieces in stock. TMK042CG2R7AD-W has 999 pieces in stock. CQ0100ARNPO8BN2R7 has 20447 pieces in stock. Inventory levels are subject to change and should be verified at time of procurement.
