The TVS042CG6R7BC-W meets all specified parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The TVS042CG6R7BC-W qualifies as a direct parametric equivalent to the MLAST042SCG6R7BWNA01 based on complete alignment of electrical, mechanical, and compliance specifications. Both parts are manufactured by Taiyo Yuden and share identical capacitance, tolerance, voltage rating, temperature coefficient, package dimensions, and regulatory compliance status.

The primary distinction between these parts is product lifecycle status. The MLAST042SCG6R7BWNA01 maintains Active status, indicating ongoing manufacturing and support. The TVS042CG6R7BC-W carries a "Not For New Designs" designation, indicating the part is in mature or declining production phase.

For new design implementations, the MLAST042SCG6R7BWNA01 is the preferred selection due to its Active status and assured long-term availability. The TVS042CG6R7BC-W is suitable for legacy system maintenance, field replacements, or applications where existing inventory is available and supply continuity is established through alternative channels.

Both parts satisfy ROHS3 compliance and EAR99 export classification requirements. Moisture sensitivity level 1 (Unlimited) indicates no special handling or baking requirements prior to assembly for both parts.

Frequently Asked Questions (FAQ)

Q: Can TVS042CG6R7BC-W be used as a direct replacement for MLAST042SCG6R7BWNA01 in existing designs?

A: Yes. The TVS042CG6R7BC-W meets all electrical and mechanical specifications of the MLAST042SCG6R7BWNA01. Both parts are identical in capacitance (6.7 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), package dimensions (01005/0402 Metric), and compliance certifications. Direct substitution is electrically and mechanically valid.

Q: What does "Not For New Designs" mean for the TVS042CG6R7BC-W?

A: "Not For New Designs" indicates the part is in a mature or declining production phase. The manufacturer does not recommend this part for new product development.
