MLAST042SCG620JWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG620JWNA01 is a 62 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. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when design flexibility permits component selection from the same electrical and mechanical parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLAST042SCG620JWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 62 pF
• Tolerance: ±5%
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 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 compliance
• Moisture Sensitivity Level 1
• REACH unaffected status

The identified substitute part TMK042CG620JC-W meets all electrical, mechanical, and compliance requirements. The primary distinction between the main part and substitute is the packaging format (Tape & Reel versus Cut Tape) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

MLAST042SCG620JWNA01 (Primary Part):

• Current active production status
• Recommended for new designs and long-term production applications
• Tape & Reel packaging suitable for automated assembly processes
• Preferred choice for medical and non-critical applications requiring active product support

TMK042CG620JC-W (Substitute Part):

• Classified as "Not For New Designs"
• Electrically and mechanically equivalent to the primary part
• Cut Tape packaging format requires manual handling or alternative assembly processes
• Suitable for legacy design support, prototype development, or applications where packaging format flexibility is acceptable
• Equivalent compliance certifications (ROHS3, REACH unaffected)

Selection between these parts should be based on production requirements, assembly capabilities, and design lifecycle stage. Both parts satisfy identical electrical and mechanical specifications for 62 pF, 25V, C0G/NP0 ceramic capacitor applications in 01005 package form factor.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG620JC-W be used as a direct replacement for MLAST042SCG620JWNA01 in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (62 pF), tolerance (±5%), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and package dimensions (01005/0402 Metric). The primary difference is packaging format (Tape & Reel versus Cut Tape) and product status. Assembly process compatibility must be evaluated based on your manufacturing equipment.

Q: What is the significance of the "Not For New Designs" status on TMK042CG620JC-W?

A: This designation indicates that Taiyo Yuden is not recommending this part number for new product development. While the part remains electrically and mechanically equivalent, the MLAST042SCG620JWNA01 (active status) is the preferred choice for new designs. The substitute part may be used for legacy system support or when specific packaging requirements necessitate its selection.

Q: Are there differences in compliance or certifications between these parts?

A: No. Both parts are ROHS3 compliant, have Moisture Sensitivity Level 1 (unlimited), and are REACH unaffected. Compliance certifications are identical.

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

A: Tape & Reel packaging is optimized for high-volume automated assembly using pick-and-place equipment. Cut Tape packaging provides individual component strips and requires manual handling or alternative feeding mechanisms. Both formats contain the same component; the difference is in supply and assembly process compatibility.

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

A: Both parts meet the same electrical specifications and compliance requirements for medical and non-critical applications. However, design validation and qualification procedures should be followed according to your medical device quality management system. The active production status of MLAST042SCG620JWNA01 may provide advantages for long-term supply chain stability in medical applications.
