Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLAST042SCG7R2BWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 7.2 pF
• Tolerance: ±0.1pF
• 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

The substitute part TMK042CG7R2BD-W meets all electrical and mechanical equivalence criteria. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) format. Both parts are manufactured by Taiyo Yuden and share identical electrical specifications and physical dimensions.

Engineering Selection Recommendations

Primary Part: MLAST042SCG7R2BWNA01

The MLAST042SCG7R2BWNA01 is the recommended selection for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. It is supplied in Tape & Reel (TR) packaging, which is standard for high-volume automated assembly operations. The part is ROHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements for medical and non-critical applications.

Substitute Part: TMK042CG7R2BD-W

The TMK042CG7R2BD-W is electrically and mechanically equivalent to the primary part and is suitable for direct substitution in existing designs where component availability is constrained. However, this part carries "Not For New Designs" product status, indicating that Taiyo Yuden does not recommend its use in new product development. The substitute is supplied in Cut Tape (CT) format, which requires different handling and assembly processes compared to Tape & Reel packaging. This packaging difference may necessitate process adjustments in automated pick-and-place assembly systems.

Both parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG7R2BD-W be used as a direct replacement for MLAST042SCG7R2BWNA01 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical, with matching capacitance (7.2 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), and physical dimensions (01005/0402 Metric). The primary difference is packaging format: Tape & Reel versus Cut Tape. Assembly equipment compatibility depends on your specific pick-and-place system's capability to handle Cut Tape format.

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

A: Tape & Reel packaging supplies components on a continuous carrier tape wound on a reel, optimized for automated high-speed assembly. Cut Tape packaging supplies the same components on shorter tape segments, typically used for lower-volume or manual assembly operations. Both formats contain identical components with identical electrical and mechanical specifications.

Q: Why is TMK042CG7R2BD-W marked "Not For New Designs"?

A: This designation indicates that Taiyo Yuden has discontinued active development and support for this part number. While the part remains functionally equivalent and available in current inventory, the manufacturer recommends using MLAST042SCG7R2BWNA01 for new product designs to ensure long-term availability and manufacturer support.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected. They meet identical regulatory requirements for medical and non-critical applications.

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

A: Electrical and mechanical interchangeability is confirmed. However, assembly process compatibility depends on your equipment's ability to handle both Tape & Reel and Cut Tape formats. Verify your pick-and-place system specifications before switching between packaging formats.

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

A: Both MLAST042SCG7R2BWNA01 and TMK042CG7R2BD-W operate across -55°C to 125°C with C0G/NP0 temperature coefficient, ensuring stable capacitance performance across this full range.
