Substitute Part Grouping Explanation

Substitution of the MLAST042SCG080BWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 8 pF
• Capacitance tolerance: ±0.1pF
• Rated voltage: 25V
• Temperature coefficient: C0G/NP0

Mechanical Equivalence Requirements:

• 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 Equivalence Requirements:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute part TMK042CG080BD-W maintains all electrical and mechanical parameters identical to the main part. The primary distinction is packaging format (Cut Tape versus Tape & Reel) and product lifecycle status. Both parts are manufactured by Taiyo Yuden and meet all specified compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: MLAST042SCG080BWNA01

The MLAST042SCG080BWNA01 is the recommended selection for new designs. This part maintains Active product status, indicating ongoing manufacturer support and availability. It is supplied in Tape & Reel (TR) packaging, which is standard for high-volume manufacturing and automated assembly processes. The part is designated for medical and non-critical applications, with full ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute Selection: TMK042CG080BD-W

The TMK042CG080BD-W is electrically and mechanically equivalent to the primary part and is suitable for applications where the substitute part's specifications are already qualified. This part carries "Not For New Designs" status, indicating it is in mature or end-of-life phase. The Cut Tape (CT) packaging format may be appropriate for lower-volume applications or manual assembly processes. Selection of this substitute should be limited to existing designs or applications where the part has been previously qualified.

Compliance Considerations:

Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly. Both parts are classified under ECCN EAR99 and HTSUS 8532.24.0020, with identical regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG080BD-W be used as a direct replacement for MLAST042SCG080BWNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters including capacitance, tolerance, voltage rating, temperature coefficient, package dimensions, and compliance certifications are identical. The primary difference is packaging format (Cut Tape versus Tape & Reel) and product lifecycle status.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on cut segments of carrier tape, typically used for lower-volume or manual assembly processes. Both formats contain the same component; the difference is in supply format and handling.

Q: Why is TMK042CG080BD-W marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life phase within the manufacturer's product portfolio. While the part remains functionally equivalent and available, the manufacturer recommends using MLAST042SCG080BWNA01 for new design implementations to ensure long-term availability and support.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts maintain identical operating temperature range (-55°C ~ 125°C), temperature coefficient (C0G/NP0), and all electrical specifications. Performance in thermal cycling and frequency response applications is equivalent.

Q: Can these parts be used interchangeably on the same PCB assembly line?

A: Interchangeability depends on assembly equipment configuration. Both parts use identical 01005 (0402 Metric) package dimensions and surface mount mounting type. However, automated assembly equipment may require different feeder configurations for Tape & Reel versus Cut Tape formats. Verify equipment compatibility before implementing substitution in production.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, carry Moisture Sensitivity Level 1 (Unlimited), and are classified as REACH Unaffected. Both are designated ECCN EAR99 for export control purposes and fall under HTSUS code 8532.24.0020.
