Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK042CG200JC-W is determined by strict equivalence across the following parameters:

Electrical Parameters:

• Capacitance: 20 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 25V (exact match required)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Mechanical Parameters:

• Package / Case: 01005 (0402 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm) (exact match required)
• Thickness: 0.009" (0.22mm) maximum (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

The identified substitute parts meet all specified electrical, mechanical, and compliance requirements. Substitution is valid based on parametric equivalence and does not require additional verification.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: Both MLAST042SCG200JWNA01 and MSAST042SCG200JWNA01 are designated as Active products and are suitable for new circuit designs. These parts provide identical electrical and mechanical performance to the TMK042CG200JC-W while offering the advantage of current product line status and ongoing manufacturer support.

For Existing Designs: The TMK042CG200JC-W may be replaced with either substitute part without modification to circuit design or PCB layout. All three parts share identical electrical characteristics, package dimensions, and compliance certifications.

Packaging Consideration: The primary difference between the main part and substitute parts is packaging format. The TMK042CG200JC-W is supplied in Cut Tape (CT) format, while both substitute parts are supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not impact component performance or compatibility.

Compliance and Regulatory: All three parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can MLAST042SCG200JWNA01 or MSAST042SCG200JWNA01 be used as direct replacements for TMK042CG200JC-W in existing assemblies?

A: Yes. Both substitute parts are parametrically equivalent across all electrical, mechanical, and compliance specifications. Direct substitution is valid without circuit modification or PCB redesign.

Q: What is the difference between the two substitute parts?

A: MLAST042SCG200JWNA01 and MSAST042SCG200JWNA01 are both manufactured by Taiyo Yuden and share identical electrical and mechanical specifications. The difference lies in their series designation (MLAS versus MSAS) and stated applications (Medical, Non-Critical versus General Purpose). Both are Active products suitable for new designs.

Q: Why is the TMK042CG200JC-W marked as "Not For New Designs"?

A: This designation indicates the part is no longer recommended for incorporation into new circuit designs. However, the part remains functional and available for existing applications or legacy system support. Active substitute parts are available for new design implementations.

Q: Does the packaging format difference (Cut Tape versus Tape & Reel) affect component performance?

A: No. Packaging format affects procurement, storage, and assembly handling only. The electrical and mechanical performance of the component itself is identical regardless of packaging format.

Q: Are all three parts RoHS3 compliant?

A: Yes. TMK042CG200JC-W, MLAST042SCG200JWNA01, and MSAST042SCG200JWNA01 are all ROHS3 Compliant with REACH Unaffected status.

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

A: All three parts share identical temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and tolerance (±5%). Selection between them is based on product status, packaging requirements, and application classification rather than performance differentiation.

Q: What is the moisture sensitivity level for these capacitors?

A: All three parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under normal storage conditions without special moisture control requirements.
