MLAST042SCG2R2AWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG2R2AWNA01 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 product status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit alternative manufacturers while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the MLAST042SCG2R2AWNA01 is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

• Capacitance value: 2.2 pF
• Tolerance: ±0.05pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 125°C
• 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
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these critical parameters. Packaging format (Tape & Reel versus Cut Tape) and product status variations do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

MLAST042SCG2R2AWNA01 (Primary Selection)

This part is the recommended choice for new designs. It maintains active product status with Taiyo Yuden, ensuring long-term availability and supply chain stability. The Tape & Reel packaging format is standard for high-volume manufacturing operations. RoHS3 compliance and MSL 1 rating satisfy regulatory and environmental requirements for medical and non-critical applications.

TMK042CG2R2AD-W (Secondary Selection)

This Taiyo Yuden part is electrically and mechanically identical to the primary part but carries "Not For New Designs" status. It is suitable for legacy system maintenance, repair, or replacement scenarios where existing inventory must be sustained. The Cut Tape packaging format may require additional handling considerations in automated assembly environments. RoHS3 compliance and MSL 1 rating are maintained.

CQ0100ARNPO8BN2R2 (Alternative Selection)

This YAGEO part provides full electrical and mechanical equivalence with active product status. It is suitable for new designs when supply diversification across manufacturers is required. The High Q feature designation indicates superior quality factor characteristics. Tape & Reel packaging aligns with standard manufacturing practices. RoHS3 compliance and MSL 1 rating are maintained. This part offers the highest current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG2R2AD-W be used as a direct replacement for MLAST042SCG2R2AWNA01?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 2.2 pF capacitance, ±0.05pF tolerance, 25V rating, C0G/NP0 temperature coefficient, -55°C to 125°C operating range, 01005 package, and identical physical dimensions. The "Not For New Designs" status does not affect functional compatibility; it indicates manufacturer lifecycle positioning. Packaging format differs (Cut Tape versus Tape & Reel) but does not impact circuit performance.

Q: What is the difference between the YAGEO CQ0100ARNPO8BN2R2 and the Taiyo Yuden alternatives?

A: The YAGEO part meets all electrical and mechanical specifications identically. The primary differences are manufacturer identity and the High Q feature designation. All three parts are RoHS3 compliant, MSL 1 rated, and suitable for the same applications. Manufacturer selection depends on supply chain strategy and inventory availability.

Q: Are there any compatibility issues with different packaging formats?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats contain identical components with different presentation methods for automated assembly. Both formats are compatible with standard surface mount assembly equipment. Selection between formats depends on manufacturing process requirements and inventory management practices.

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

A: Yes. All three parts maintain RoHS3 compliance and MSL 1 rating, meeting regulatory requirements for medical and non-critical applications. The identical electrical specifications (2.2 pF, 25V, C0G/NP0, -55°C to 125°C) ensure functional equivalence in medical device circuits.

Q: What does the ±0.05pF tolerance mean for circuit performance?

A: The ±0.05pF tolerance represents the maximum deviation from the nominal 2.2 pF value. This tight tolerance is maintained across all three substitute parts and ensures consistent circuit behavior in applications requiring precise capacitance values, such as RF tuning and frequency-critical circuits.

Q: Is the High Q feature of the YAGEO part significant for substitution?

A: The High Q designation indicates superior quality factor performance in the YAGEO CQ0100ARNPO8BN2R2. This feature does not prevent substitution but may provide performance advantages in high-frequency or low-loss applications. All three parts meet the specified electrical parameters and are functionally equivalent for standard applications.
