MLAST042SCG2R2BWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG2R2BWNA01 is a 2.2 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 designed for medical and non-critical applications. The part is currently in active production status. Substitute parts are identified for applications requiring equivalent electrical and mechanical specifications, alternative packaging formats, or sourcing flexibility from qualified manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the MLAST042SCG2R2BWNA01 are qualified based on the following electrical and mechanical parameters:

Substitution Criteria:

• Capacitance value: 2.2 pF
• Tolerance: ±0.1 pF
• Voltage rating: 25V minimum
• Temperature coefficient: C0G or NP0
• Operating temperature range: -55°C to 125°C minimum
• Package: 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
• Moisture sensitivity: MSL 1 (Unlimited)
• Compliance: ROHS3 Compliant

Two substitute parts meet these criteria with variations in packaging format and product status. Packaging differences (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

MLAST042SCG2R2BWNA01 (Primary Part)

• Active production status
• Recommended for new designs
• Tape & Reel packaging suitable for automated assembly
• Taiyo Yuden manufacturing

TVS042CG2R2BC-W (Substitute)

• Not recommended for new designs
• Identical electrical and mechanical specifications
• Cut Tape packaging format
• Use only for legacy system support or when Tape & Reel format is unavailable
• Taiyo Yuden manufacturing maintains consistency with primary part

CQ0100BRNPO8BN2R2 (Substitute)

• Active production status
• Suitable for new designs
• Tape & Reel packaging compatible with automated assembly
• YAGEO manufacturer provides alternative sourcing
• High Q feature specification available
• Recommended when primary part availability is constrained

Selection between active production parts (MLAST042SCG2R2BWNA01 and CQ0100BRNPO8BN2R2) is based on supply chain requirements and manufacturer preference. The "Not For New Designs" status of TVS042CG2R2BC-W restricts its use to legacy applications only.

Frequently Asked Questions (FAQ)

Q: Can TVS042CG2R2BC-W be used as a direct replacement for MLAST042SCG2R2BWNA01?

A: TVS042CG2R2BC-W meets all electrical and mechanical specifications for direct substitution. However, its "Not For New Designs" product status restricts use to legacy system maintenance. The primary difference is packaging format (Cut Tape versus Tape & Reel), which does not affect circuit performance but may impact assembly process compatibility.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides components on tape segments, typically for manual assembly or lower-volume applications. Electrical and mechanical specifications remain identical between formats.

Q: Is CQ0100BRNPO8BN2R2 suitable for new product designs?

A: Yes. CQ0100BRNPO8BN2R2 is in active production status and meets all electrical and mechanical requirements for new designs. It provides an alternative sourcing option from YAGEO while maintaining full compatibility with the primary Taiyo Yuden part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including the primary part and substitutes, are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in medical applications?

A: All parts meet the specified electrical and mechanical parameters for medical and non-critical applications. However, application-specific qualification requirements and regulatory documentation must be evaluated independently for each manufacturer and part number.

Q: What does C0G/NP0 temperature coefficient mean?

A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic, indicating minimal capacitance variation across the -55°C to 125°C operating temperature range. This stability is critical for precision circuit applications.
