Substitute Part Grouping Explanation

Substitution of the TMK042CG6R5CD-W is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts maintain identical specifications for capacitance (6.5 pF), tolerance (±0.25pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (01005/0402 Metric), and physical dimensions (0.016" L x 0.008" W, 0.009" max thickness).

All substitute parts are manufactured by Taiyo Yuden and comply with ROHS3 standards. The substitutes differ only in their product series designation (MLAS, MSAR, MSAS versus the original M series) and product status (Active versus Not For New Designs). These differences reflect manufacturing line updates and product lifecycle management rather than functional or electrical changes.

The key parameters enabling substitution are:

• Identical capacitance and tolerance values
• Identical voltage rating
• Identical temperature coefficient classification
• Identical package and physical dimensions
• Equivalent compliance certifications

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are direct functional equivalents to the TMK042CG6R5CD-W and are suitable for component replacement in existing designs. The primary distinction among the substitutes is product status: all three alternatives are classified as Active products, whereas the original part is Not For New Designs.

MLAST042SCG6R5CWNA01 (MLAS Series): This part is designated for Medical and Non-Critical applications. It carries REACH Unaffected status in addition to ROHS3 compliance. This option is appropriate for applications requiring medical-grade component traceability.

MSART042SCG6R5CWRA01 (MSAR Series): This part is designated for General Purpose applications and carries ROHS3 compliance. It does not include REACH status documentation in the provided specifications.

MSAST042SCG6R5CWNA01 (MSAS Series): This part is designated for General Purpose applications and carries both ROHS3 compliance and REACH Unaffected status. This option provides the broadest regulatory compliance documentation.

For applications where the original TMK042CG6R5CD-W is currently in use, any of the three substitute parts provide equivalent electrical and mechanical performance. Selection among the substitutes should be based on application requirements (Medical versus General Purpose) and regulatory compliance documentation needs (REACH status).

Frequently Asked Questions (FAQ)

Q: Can MLAST042SCG6R5CWNA01, MSART042SCG6R5CWRA01, and MSAST042SCG6R5CWNA01 be used interchangeably with TMK042CG6R5CD-W?

A: Yes. All three substitute parts maintain identical electrical specifications (6.5 pF capacitance, ±0.25pF tolerance, 25V rating, C0G/NP0 temperature coefficient) and mechanical specifications (01005/0402 package, identical physical dimensions). They are functionally equivalent for circuit applications.

Q: Why is the original TMK042CG6R5CD-W marked as Not For New Designs?

A: This designation indicates the part has been superseded in Taiyo Yuden's product line. The substitute parts from the MLAS, MSAR, and MSAS series represent the current active product offerings with identical specifications.

Q: Are there differences in physical footprint between the original part and substitutes?

A: No. All parts share identical package specifications (01005/0402 Metric), physical dimensions (0.016" L x 0.008" W), and maximum thickness (0.009"). They are pin-compatible and footprint-compatible for PCB assembly.

Q: What is the difference between the MLAS, MSAR, and MSAS series designations?

A: These designations represent different product series within Taiyo Yuden's ceramic capacitor portfolio. The MLAS series includes Medical and Non-Critical application variants. The MSAR and MSAS series are designated for General Purpose applications. All three series maintain identical electrical and mechanical specifications for this 6.5 pF, 25V capacitor value.

Q: Do all substitute parts have the same compliance certifications?

A: All parts are ROHS3 compliant. MLAST042SCG6R5CWNA01 and MSAST042SCG6R5CWNA01 carry REACH Unaffected status. MSART042SCG6R5CWRA01 does not include REACH status in the provided specifications. All parts have Moisture Sensitivity Level 1 (Unlimited).

Q: Which substitute should be selected for medical device applications?

A: MLAST042SCG6R5CWNA01 is designated for Medical and Non-Critical applications and includes REACH Unaffected status, making it the appropriate choice for medical device requirements.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: TMK042CG6R5CD-W (1002 pcs), MLAST042SCG6R5CWNA01 (724 pcs), MSART042SCG6R5CWRA01 (678 pcs), and MSAST042SCG6R5CWNA01 (1074 pcs). Availability should be confirmed with the component supplier for production requirements.
