MLAST042SCG1R6AWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG1R6AWNA01 is a 1.6 pF ceramic capacitor manufactured by Taiyo Yuden, designed for surface mount applications in the 01005 (0402 Metric) package. This component operates at 25V with C0G/NP0 temperature coefficient characteristics, suitable 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, extended lead times, or when design requirements permit alternative packaging formats while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the MLAST042SCG1R6AWNA01 is determined by strict equivalence across the following parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 1.6 pF
• Tolerance: ±0.05pF
• Voltage Rating: 25V
• 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):

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

Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape) and product status classification, provided all electrical, mechanical, and compliance parameters remain identical. The TMK042CG1R6AD-W meets all substitution criteria despite its "Not For New Designs" status and alternative packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

MLAST042SCG1R6AWNA01 (Primary Selection): This part is the recommended choice for new designs. It maintains active production status with Taiyo Yuden and is supplied in Tape & Reel packaging, which is standard for automated assembly operations. The part carries ROHS3 compliance and unlimited moisture sensitivity rating, suitable for medical and non-critical applications. Current inventory of 808 pieces supports immediate availability.

TMK042CG1R6AD-W (Substitute Selection): This part is electrically and mechanically equivalent to the primary part and is suitable for direct substitution in existing designs or when the primary part is unavailable. 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 part is supplied in Cut Tape packaging rather than Tape & Reel format, which may require alternative handling procedures in automated assembly environments. Higher inventory availability (2224 pieces) may provide supply advantages in specific situations. ROHS3 compliance and unlimited MSL rating are maintained.

Selection between these parts should be based on design phase (new versus existing), assembly process requirements (Tape & Reel versus Cut Tape capability), and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG1R6AD-W be used as a direct replacement for MLAST042SCG1R6AWNA01?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 1.6 pF capacitance, ±0.05pF tolerance, 25V rating, C0G/NP0 temperature coefficient, -55°C to 125°C operating range, and 01005 (0402 Metric) package dimensions. 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 TMK042CG1R6AD-W?

A: This designation indicates the part is in a mature or end-of-life phase. While the part remains functionally equivalent and available, it is not recommended for incorporation into new product designs. It is suitable for sustaining production of existing designs or as a temporary substitute during supply constraints.

Q: Does the packaging format difference affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape) affects only the physical delivery and handling method, not the electrical or mechanical characteristics of the capacitor itself. Both formats contain identical components.

Q: Are both parts suitable for medical applications?

A: The MLAST042SCG1R6AWNA01 is specified for medical and non-critical applications. The TMK042CG1R6AD-W is specified for general purpose applications. Both parts meet ROHS3 compliance and carry unlimited MSL rating. Application suitability depends on specific medical device requirements and regulatory classifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C with C0G/NP0 temperature coefficient, ensuring stable capacitance performance across this full range.

Q: Can these parts be used interchangeably in automated assembly?

A: Electrical and mechanical interchangeability is confirmed. However, assembly process compatibility depends on equipment capability to handle both Tape & Reel (MLAST042SCG1R6AWNA01) and Cut Tape (TMK042CG1R6AD-W) formats. Verify assembly equipment specifications before switching between packaging formats.
