MLAST042SCG100DWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG100DWNA01 is a 10 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 full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when Tape & Reel packaging is unavailable or when alternative sourcing from equivalent product lines is required to maintain supply chain continuity. The identified substitute maintains identical electrical specifications and mechanical dimensions while offering different packaging and product lifecycle status.

Substitute Part Grouping Explanation

Substitution of the MLAST042SCG100DWNA01 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part TMK042CG100DD-W qualifies as a parametric equivalent because it maintains identical specifications in the following key areas:

Electrical Parameters:

• Capacitance: 10 pF (identical)
• Tolerance: ±0.5pF (identical)
• Voltage Rating: 25V (identical)
• Temperature Coefficient: C0G, NP0 (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)

Mechanical Parameters:

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

Compliance Parameters:

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

The primary difference between the main part and substitute is packaging format: MLAST042SCG100DWNA01 is supplied in Tape & Reel (TR), while TMK042CG100DD-W is supplied in Cut Tape (CT). Both parts are manufactured by Taiyo Yuden and share the same dielectric material and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

MLAST042SCG100DWNA01 (Primary Selection)

The MLAST042SCG100DWNA01 maintains Active product status, indicating ongoing manufacturer support and continued availability. This part is suitable for new design implementations and long-term production requirements. The Tape & Reel packaging format supports automated assembly processes with standard pick-and-place equipment.

TMK042CG100DD-W (Substitute Selection)

The TMK042CG100DD-W is designated as Not For New Designs, indicating this part is in mature or end-of-life status within the Taiyo Yuden product portfolio. This substitute is electrically and mechanically equivalent and maintains full RoHS3 and REACH compliance. The Cut Tape packaging format may require alternative handling procedures depending on assembly line configuration. This part is appropriate for legacy system maintenance, repair operations, or situations where Tape & Reel packaging is unavailable.

Both parts carry identical compliance certifications (RoHS3 Compliant, REACH Unaffected, EAR99 ECCN classification) and are suitable for Medical and General Purpose applications within their rated electrical and thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG100DD-W be used as a direct replacement for MLAST042SCG100DWNA01 in production assembly?

A: Yes, from an electrical and mechanical standpoint. Both parts are identical in capacitance (10 pF), tolerance (±0.5pF), voltage rating (25V), temperature coefficient (C0G/NP0), package size (01005/0402 Metric), and all compliance parameters. The primary difference is packaging format: Cut Tape (CT) versus Tape & Reel (TR). Assembly line compatibility depends on whether your pick-and-place equipment can accommodate Cut Tape feeding.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous carrier tape wound on a reel, optimized for automated high-volume assembly. Cut Tape packaging supplies the same carrier tape in shorter segments, typically 2-inch or 4-inch lengths. Cut Tape is often used for lower-volume orders or when component inventory is being transitioned between product lines.

Q: Are there any thermal or electrical performance differences between these two parts?

A: No. Both parts operate across the identical temperature range (-55°C ~ 125°C) and maintain the same C0G/NP0 temperature coefficient characteristics. Electrical performance, including capacitance stability and voltage rating, is identical.

Q: Why is TMK042CG100DD-W marked as "Not For New Designs"?

A: This designation indicates the part is in mature lifecycle status within Taiyo Yuden's product portfolio. The MLAST042SCG100DWNA01 (Active status) is the recommended selection for new design implementations. The TMK042CG100DD-W remains available for existing applications and legacy system support.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MLAST042SCG100DWNA01 and TMK042CG100DD-W carry RoHS3 Compliant status and are REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage or handling.
