Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMK042CG030CD-W is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 3 pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Package / Case: 01005 (0402 Metric)
• Operating Temperature Range: -55°C ~ 125°C
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Thickness (Max): 0.009" (0.22mm)

Allowable Variation:

• Tolerance: ±0.25pF or tighter (±0.05pF acceptable)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT)
• Product Status: Active or Not For New Designs
• Series Designation: May vary by manufacturer

All substitute parts listed meet these mandatory parameters and are therefore electrically and mechanically interchangeable with the TMK042CG030CD-W in applications requiring 3 pF capacitance at 25V with C0G/NP0 stability.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation for Active Designs:

For new designs and ongoing production, MLAST042SCG030CWNA01 (Taiyo Yuden, Active status) or MSAST042SCG030CWNA01 (Taiyo Yuden, Active status) are preferred substitutes. Both parts maintain identical electrical specifications to the TMK042CG030CD-W while offering Active product status, ensuring long-term supply availability and manufacturer support.

Cross-Manufacturer Alternatives:

KGU02ACG1E3R0CH (KYOCERA AVX) and KGM02ACG1E3R0CH (KYOCERA AVX) provide equivalent electrical performance with Active status. KGU02ACG1E3R0CH is specified for RF, Microwave, and High Frequency applications with High Q and Low Loss characteristics, making it suitable for demanding signal integrity requirements.

CC0100CRNPO8BN3R0 (YAGEO) offers equivalent specifications with Active status and represents a cross-manufacturer alternative from a major capacitor supplier.

Tolerance Consideration:

TMK042CG030AD-W provides tighter tolerance (±0.05pF versus ±0.25pF) and is suitable for applications requiring enhanced capacitance precision. This part is available in Cut Tape (CT) packaging format.

Compliance Status:

All substitute parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory requirements of the original part.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG030AD-W be used as a direct replacement for TMK042CG030CD-W?

A: Yes. TMK042CG030AD-W is electrically and mechanically compatible. The primary differences are tighter tolerance (±0.05pF versus ±0.25pF) and packaging format (Cut Tape versus Tape & Reel). The tighter tolerance represents an improvement for precision-sensitive applications.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging provides components on tape segments, typically used for lower-volume or manual assembly operations. Both formats contain identical components; the difference is in supply format only.

Q: Are KYOCERA AVX parts (KGM02ACG1E3R0CH and KGU02ACG1E3R0CH) interchangeable?

A: Yes. Both KYOCERA AVX parts meet all mandatory electrical and mechanical parameters. KGU02ACG1E3R0CH is specified for RF, Microwave, and High Frequency applications with High Q and Low Loss characteristics, while KGM02ACG1E3R0CH is designated for general-purpose applications. Selection depends on application requirements.

Q: Why is the original TMK042CG030CD-W marked "Not For New Designs"?

A: "Not For New Designs" status indicates the part has reached end-of-life. Existing inventory remains available, but the manufacturer does not recommend this part for new product development. Active alternatives such as MLAST042SCG030CWNA01 or MSAST042SCG030CWNA01 should be used for new designs.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All substitute parts are specified for 01005 (0402 Metric) package with dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum thickness of 0.009" (0.22mm). They are mechanically interchangeable on PCB layouts designed for this form factor.

Q: What does C0G/NP0 temperature coefficient mean?

A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic, representing near-zero temperature coefficient performance. This ensures capacitance remains stable across the -55°C to 125°C operating temperature range, with minimal drift due to temperature variations.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant, meeting the same environmental and regulatory requirements as the original TMK042CG030CD-W.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has minimal moisture sensitivity and does not require special moisture control during storage, handling, or assembly. This is the least restrictive moisture sensitivity level and simplifies supply chain management.
