MLASE042SCG331JWNA01 Equivalent & Substitute Parts

Part Overview

The MLASE042SCG331JWNA01 is a 330 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 16V operation 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 maintains an Active product status with 940 pieces currently in stock. Substitute parts become necessary when tape and reel packaging is unavailable or when alternative product series are required to meet procurement timelines or inventory constraints.

Substitute Part Grouping Explanation

Substitution of the MLASE042SCG331JWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 330 pF
• Tolerance: ±5%
• Voltage Rating: 16V
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

• 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 (Must Match Exactly):

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

The EMK042CG331JC-W qualifies as a parametric equivalent substitute. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility and represent the primary distinction between the main part and its substitute.

Engineering Selection Recommendations

Primary Selection: MLASE042SCG331JWNA01

The MLASE042SCG331JWNA01 is the recommended choice for new designs. This part maintains Active product status, indicating ongoing manufacturer support and availability. It is supplied in Tape & Reel packaging, which is standard for automated assembly processes. Current inventory of 940 pieces supports immediate procurement requirements.

Substitute Selection: EMK042CG331JC-W

The EMK042CG331JC-W serves as a parametric equivalent for applications where the primary part is unavailable. This substitute maintains identical electrical and mechanical specifications, including capacitance, voltage rating, temperature coefficient, and physical dimensions. However, this part carries a "Not For New Designs" status, indicating it is in the mature or end-of-life phase of its product lifecycle. The substitute is supplied in Cut Tape packaging rather than Tape & Reel format.

Both parts are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for medical and non-critical applications. Selection between these parts should prioritize the Active status part for new designs while reserving the substitute for legacy system maintenance or when primary part availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can EMK042CG331JC-W be used as a direct replacement for MLASE042SCG331JWNA01?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (330 pF), voltage rating (16V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and physical dimensions (01005/0402 Metric package). 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 EMK042CG331JC-W?

A: This designation indicates the part is in a mature or end-of-life phase. While the part remains functionally equivalent and available in current inventory (22,176 pieces), the manufacturer does not recommend its use in new product designs. This status typically reflects reduced manufacturing priority and potential future discontinuation. New designs should specify the MLASE042SCG331JWNA01, which maintains Active status.

Q: Does the packaging format difference affect circuit performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats are handling and assembly methods only. They do not affect the electrical or mechanical properties of the capacitor itself. The choice between formats depends on assembly equipment compatibility and procurement workflow requirements.

Q: Are both parts suitable for medical applications?

A: The MLASE042SCG331JWNA01 is specified for Medical and Non-Critical applications. The EMK042CG331JC-W is specified for General Purpose applications. For medical device applications, the MLASE042SCG331JWNA01 is the appropriate selection based on its documented application category.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly. Both are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Q: Can these parts be interchanged in existing assemblies?

A: Yes, provided the assembly equipment supports the packaging format of the substitute part. If the assembly line is configured for Tape & Reel format, the EMK042CG331JC-W in Cut Tape format would require manual handling or equipment reconfiguration. Electrical and mechanical compatibility is complete.
