MLAST042SCG3R2BWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG3R2BWNA01 is a 3.2 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. Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when alternative packaging formats are required for manufacturing processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLAST042SCG3R2BWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 3.2 pF
• Tolerance: ±0.1pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

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

Compliance Parameters:

• RoHS3 Compliant
• REACH Unaffected
• Operating temperature range: -55°C ~ 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute part matches all electrical, mechanical, and compliance parameters. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility and represent alternative supply chain options.

Engineering Selection Recommendations

Primary Part Selection: The MLAST042SCG3R2BWNA01 is the recommended selection for new designs. This part maintains Active product status from Taiyo Yuden, ensuring long-term availability and continued manufacturing support. The Tape & Reel packaging format is optimized for high-volume automated assembly processes.

Substitute Part Consideration: The TMK042CG3R2BD-W is electrically and mechanically equivalent to the MLAST042SCG3R2BWNA01 across all critical parameters. However, this part carries a "Not For New Designs" product status designation. The substitute part is suitable for replacement, repair, or legacy system applications where the primary part is unavailable. The Cut Tape packaging format may require manual handling or alternative feeder compatibility depending on assembly equipment configuration.

Compliance Basis: Both parts maintain identical RoHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in medical and non-critical applications. Moisture Sensitivity Level 1 (Unlimited) classification indicates no special storage or handling requirements for either part.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG3R2BD-W be used as a direct replacement for MLAST042SCG3R2BWNA01?

A: Yes. The substitute part is electrically and mechanically equivalent. All electrical parameters (capacitance, tolerance, voltage rating, temperature coefficient), physical dimensions, and compliance certifications are identical. The primary difference is packaging format (Cut Tape versus Tape & Reel) and product lifecycle status.

Q: What is the significance of the "Not For New Designs" status on the substitute part?

A: This designation indicates that Taiyo Yuden is not recommending the TMK042CG3R2BD-W for new product development. The part remains available and functional for existing applications, repairs, and legacy systems. For new designs, the MLAST042SCG3R2BWNA01 (Active status) is the appropriate selection.

Q: Are there packaging compatibility concerns between Tape & Reel and Cut Tape formats?

A: Packaging format differences do not affect electrical or mechanical performance. However, assembly equipment compatibility varies. Tape & Reel format is standard for automated pick-and-place machines. Cut Tape format requires manual handling or specialized feeder systems. Verify your assembly equipment specifications before selecting the Cut Tape variant.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both MLAST042SCG3R2BWNA01 and TMK042CG3R2BD-W are ROHS3 Compliant and REACH Unaffected. Both maintain Moisture Sensitivity Level 1 (Unlimited), requiring no special storage conditions.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: capacitance (3.2 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (01005/0402 Metric), and mounting method (Surface Mount, MLCC). All these parameters are identical between the main part and substitute.

Q: Can the substitute part be used in medical applications?

A: The MLAST042SCG3R2BWNA01 is specified for medical and non-critical applications. The TMK042CG3R2BD-W is specified for general purpose applications. Both parts meet identical electrical, mechanical, and compliance standards. Application suitability depends on your specific medical device requirements and regulatory pathway.
