MLAST042SCG4R7BWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG4R7BWNA01 is a 4.7 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 classified as Active product status. Substitute parts are identified for applications requiring equivalent electrical and mechanical specifications, particularly when the primary part is unavailable or when alternative packaging formats are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MLAST042SCG4R7BWNA01 are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 4.7 pF
• Capacitance tolerance: ±0.1pF
• Voltage rating: 25V (minimum)
• Temperature coefficient: C0G/NP0

Mechanical Equivalence Criteria:

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

Compliance Criteria:

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

Parts meeting all electrical, mechanical, and compliance parameters are classified as parametric equivalents. Packaging format variations (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility and are noted separately.

Engineering Selection Recommendations

MLAST042SCG4R7BWNA01 (Primary Part)

This part maintains Active product status and is recommended for new designs. It is supplied in Tape & Reel packaging format and carries full ROHS3 and REACH compliance documentation.

TMK042CG4R7BD-W (Taiyo Yuden Substitute)

This part is electrically and mechanically equivalent to the main part number. However, it carries Not For New Designs product status, indicating it is in mature or declining production phase. The part is supplied in Cut Tape packaging format rather than Tape & Reel. Selection of this substitute is appropriate only for legacy design support, repair, or rework applications where the original part number is unavailable. For new designs, the primary part number MLAST042SCG4R7BWNA01 is preferred.

CQ0100BRNPO8BN4R7 (YAGEO Substitute)

This part is electrically and mechanically equivalent to the main part number and maintains Active product status. It is manufactured by YAGEO and supplied in Tape & Reel packaging format. This substitute is suitable for applications where multi-source qualification is required or where YAGEO components are preferred. The part meets all specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG4R7BD-W be used as a direct replacement for MLAST042SCG4R7BWNA01?

A: TMK042CG4R7BD-W is electrically and mechanically equivalent and can function as a direct replacement. However, it carries Not For New Designs status. The primary difference is packaging format: TMK042CG4R7BD-W is supplied in Cut Tape while MLAST042SCG4R7BWNA01 is supplied in Tape & Reel. Cut Tape format requires different handling and assembly processes. For new designs, MLAST042SCG4R7BWNA01 is the recommended choice.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on a reel, suitable for automated pick-and-place assembly equipment. Cut Tape packaging supplies components on shorter tape segments, typically used for manual assembly or lower-volume production. Both formats contain identical components; the difference is in supply and handling method.

Q: Is CQ0100BRNPO8BN4R7 from YAGEO fully compatible with the Taiyo Yuden part?

A: CQ0100BRNPO8BN4R7 meets all specified electrical parameters (4.7 pF, ±0.1pF, 25V, C0G/NP0), mechanical parameters (01005 package, identical dimensions), and environmental specifications (MSL 1). It is a parametric equivalent suitable for applications requiring multi-source qualification.

Q: What does C0G/NP0 temperature coefficient mean?

A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic. This indicates the capacitor has minimal capacitance change across the operating temperature range of -55°C to 125°C, making it suitable for precision applications where temperature stability is critical.

Q: Can these parts be used in medical applications?

A: The MLAST042SCG4R7BWNA01 is specified for Medical and Non-Critical applications. Substitute parts should be evaluated against specific medical device requirements and regulatory standards applicable to the end application. Compliance documentation should be reviewed for each substitute part.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required prior to assembly.
