Substitute Part Grouping Explanation

Substitution of the TMK042CGR75CD-W is determined by strict equivalence across the following critical parameters: capacitance value (0.75 pF), rated voltage (25V), temperature coefficient (C0G/NP0), package type (01005/0402 Metric), and mounting technology (Surface Mount MLCC). All substitute parts maintain identical capacitance, voltage rating, temperature coefficient, and physical dimensions. Tolerance variations and packaging format differences (Tape & Reel versus Cut Tape) do not affect functional interchangeability in circuit applications. Product status transitions from legacy to active series are permitted where electrical and mechanical specifications remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

TMK042CGR75AD-W serves as a direct upgrade path within the legacy M-series product line. This part maintains identical electrical specifications with improved tolerance (±0.05pF versus ±0.25pF), offering enhanced precision for applications requiring tighter capacitance control. Packaging format differs as Cut Tape (CT) rather than Tape & Reel (TR), requiring process adaptation for automated assembly operations. Both parts retain "Not For New Designs" status.

MLAST042SCGR75CWNA01 and MSAST042SCGR75CWNA01 represent transitions to active product series (MLAS and MSAS respectively) with identical electrical and mechanical specifications to the main part. Both parts are designated as Active products, supporting long-term availability and supply chain continuity. MLAST042SCGR75CWNA01 is specified for Medical and Non-Critical applications, while MSAST042SCGR75CWNA01 is designated for General Purpose applications. Both are supplied in Tape & Reel (TR) packaging, maintaining process compatibility with the original part.

For new design initiatives, MLAST042SCGR75CWNA01 or MSAST042SCGR75CWNA01 are preferred selections based on Active product status. For existing designs currently using TMK042CGR75CD-W, all listed substitutes provide functional equivalence without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can TMK042CGR75AD-W replace TMK042CGR75CD-W in existing assemblies?

A: Yes. Both parts share identical capacitance (0.75 pF), voltage rating (25V), temperature coefficient (C0G/NP0), package type (01005/0402 Metric), and physical dimensions. The tolerance improvement in TMK042CGR75AD-W (±0.05pF versus ±0.25pF) provides enhanced precision without affecting circuit compatibility. Packaging format differs (Cut Tape versus Tape & Reel), requiring process adjustment for automated placement equipment.

Q: What is the difference between MLAST042SCGR75CWNA01 and MSAST042SCGR75CWNA01?

A: Both parts are electrically and mechanically identical to TMK042CGR75CD-W. The primary distinction is application classification: MLAST042SCGR75CWNA01 is designated for Medical and Non-Critical applications, while MSAST042SCGR75CWNA01 is designated for General Purpose applications. Both are Active products with Tape & Reel packaging.

Q: Why should I transition from TMK042CGR75CD-W to MLAST042SCGR75CWNA01 or MSAST042SCGR75CWNA01?

A: The original TMK042CGR75CD-W carries "Not For New Designs" status, indicating legacy classification. MLAST042SCGR75CWNA01 and MSAST042SCGR75CWNA01 are Active products, ensuring long-term availability, supply chain stability, and manufacturer support. All electrical and mechanical specifications remain identical, enabling direct substitution without circuit modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TMK042CGR75CD-W, TMK042CGR75AD-W, MLAST042SCGR75CWNA01, and MSAST042SCGR75CWNA01 are all ROHS3 Compliant.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Can these parts be used interchangeably in high-precision applications?

A: TMK042CGR75AD-W offers tighter tolerance (±0.05pF) compared to TMK042CGR75CD-W, MLAST042SCGR75CWNA01, and MSAST042SCGR75CWNA01 (all ±0.25pF). Selection depends on circuit tolerance requirements. For applications requiring ±0.05pF tolerance, TMK042CGR75AD-W is the appropriate choice.
