MLAST042SCG820JWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG820JWNA01 is an 82 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 become necessary when the primary part experiences supply constraints, inventory depletion, or when alternative packaging formats better suit manufacturing requirements.

Substitute Part Grouping Explanation

Substitution of the MLAST042SCG820JWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 82 pF
• Tolerance: ±5%
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Physical 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
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

The substitute part TMK042CG820JC-W meets all electrical and physical specifications. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. Both parts are manufactured by Taiyo Yuden and share identical electrical characteristics and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The MLAST042SCG820JWNA01 is the recommended selection for new designs. This part maintains active production status and is suitable for medical and non-critical applications. It is supplied in Tape & Reel format, which is standard for high-volume automated assembly operations.

Substitute Part Selection: The TMK042CG820JC-W serves as a functional equivalent for applications where the primary part is unavailable. This substitute is electrically and physically identical to the main part and maintains full compliance with RoHS3 and REACH requirements. However, this part carries a "Not For New Designs" status, indicating it is in mature or declining production phase. The Cut Tape packaging format requires manual handling or specialized equipment for automated placement, which may impact manufacturing efficiency compared to Tape & Reel format.

Compliance Considerations: Both parts are ROHS3 compliant and REACH unaffected, making them suitable for regulated applications including medical devices. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, eliminating special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG820JC-W be used as a direct replacement for MLAST042SCG820JWNA01?

A: Yes, from an electrical and physical standpoint. Both parts have identical capacitance (82 pF), tolerance (±5%), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and physical dimensions (01005/0402 Metric). The primary difference is packaging format: Tape & Reel versus Cut Tape. Manufacturing processes must accommodate the different packaging format.

Q: What is the significance of the "Not For New Designs" status on TMK042CG820JC-W?

A: This designation indicates the part is in mature production phase and may have limited availability or extended lead times. For new product development, the MLAST042SCG820JWNA01 (Active status) is the preferred choice to ensure long-term supply continuity.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Both are suitable for medical and regulated applications.

Q: How does packaging format affect component selection?

A: The MLAST042SCG820JWNA01 is supplied in Tape & Reel format, which integrates directly with standard pick-and-place equipment for automated assembly. The TMK042CG820JC-W is supplied in Cut Tape format, which requires manual feeding or specialized tape-to-reel conversion equipment. This impacts assembly line compatibility and labor requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.016" L x 0.008" W (0.40mm x 0.20mm) with a maximum thickness of 0.009" (0.22mm). They are mechanically interchangeable in PCB layouts and assembly fixtures.

Q: Can these parts be used in medical applications?

A: The MLAST042SCG820JWNA01 is explicitly rated for medical applications. The TMK042CG820JC-W is rated for general purpose applications. Both maintain the same compliance certifications (ROHS3, REACH unaffected) and moisture sensitivity levels. Application suitability depends on specific medical device requirements and design validation protocols.
