MLAST042SCG030AWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG030AWNA01 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 maintains Active product status with 761 units currently in stock.

Substitute parts become necessary when primary inventory is depleted, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLAST042SCG030AWNA01 is determined by strict equivalence across the following parameters:

Electrical Specifications:

• Capacitance value: 3 pF
• Tolerance: ±0.05 pF
• Voltage rating: 25 V
• Temperature coefficient: C0G/NP0

Mechanical Specifications:

• Package / Case: 01005 (0402 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.016" L × 0.008" W (0.40mm × 0.20mm)
• Thickness: 0.009" (0.22mm) maximum

Compliance & Environmental:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

Parts meeting all these criteria are classified as parametric equivalents. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility and represent logistical variations only.

Engineering Selection Recommendations

MLAST042SCG030AWNA01 (Primary Part)

This part maintains Active product status and is recommended for new designs. It is supplied in Tape & Reel packaging, which is standard for automated assembly processes. Current inventory of 761 units supports immediate procurement for production requirements.

TMK042CG030AD-W (Taiyo Yuden Substitute)

This part is electrically and mechanically identical to the primary part but carries a "Not For New Designs" product status designation. It is supplied in Cut Tape packaging, which may require manual handling or alternative feeder compatibility depending on assembly equipment configuration. This part is suitable only for legacy design support or when Cut Tape format is specifically required by manufacturing processes. Inventory of 2060 units is available.

CQ0100ARNPO8BN3R0 (YAGEO Substitute)

This part is electrically and mechanically identical to the primary part and maintains Active product status. It is manufactured by YAGEO and supplied in Tape & Reel packaging compatible with standard automated assembly equipment. The part includes High Q feature designation. Inventory of 20653 units provides substantial availability. This part is suitable for new designs when multi-source qualification is required or when YAGEO supply chain preference is established.

All three parts satisfy identical electrical specifications, mechanical form factors, and compliance requirements. Selection between them is determined by product status requirements, packaging format compatibility with manufacturing equipment, and supply chain strategy.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG030AD-W be used as a direct replacement for MLAST042SCG030AWNA01?

A: Yes, from an electrical and mechanical standpoint. Both parts are identical in capacitance (3 pF), tolerance (±0.05 pF), voltage rating (25 V), temperature coefficient (C0G/NP0), package size (01005/0402 Metric), and all compliance certifications. The primary difference is packaging format (Cut Tape versus Tape & Reel) and product status (Not For New Designs). Packaging format compatibility depends on your assembly equipment's feeder capability.

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 a reel, designed for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically requiring manual handling or specialized feeder systems. Both formats contain identical components; the difference is logistical and equipment-dependent.

Q: Why is TMK042CG030AD-W marked "Not For New Designs"?

A: This designation indicates the manufacturer has transitioned this part to legacy status and is not actively promoting it for new product development. While the part remains functionally equivalent and available, Taiyo Yuden recommends using MLAST042SCG030AWNA01 for new designs. Existing designs using TMK042CG030AD-W may continue to source this part for production.

Q: Is CQ0100ARNPO8BN3R0 from YAGEO fully compatible with the Taiyo Yuden parts?

A: Yes. The YAGEO CQ0100ARNPO8BN3R0 meets all electrical specifications (3 pF, ±0.05 pF, 25 V, C0G/NP0), mechanical dimensions (01005/0402 Metric), operating temperature range (-55°C to 125°C), and compliance certifications (ROHS3, MSL 1). It is supplied in Tape & Reel format and maintains Active product status. The High Q feature is an additional characteristic that does not affect compatibility.

Q: Can I mix these parts in the same production batch?

A: Yes, all three parts are parametrically equivalent and can be used interchangeably in the same circuit design. However, manufacturing best practice typically specifies a single part number per assembly to maintain traceability and simplify quality control documentation.

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

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life under normal storage conditions and does not require special moisture-controlled packaging or baking procedures prior to soldering. This is the least restrictive MSL rating and simplifies inventory management and assembly logistics.

Q: Are all three parts RoHS3 compliant?

A: Yes. MLAST042SCG030AWNA01, TMK042CG030AD-W, and CQ0100ARNPO8BN3R0 are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.
