Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK042CG3R3CD-W is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 3.3 pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Package / Case: 01005 (0402 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C

Allowable Variation:

• Tolerance: Parts with ±0.1pF tolerance are acceptable upgrades from the original ±0.25pF specification
• Packaging Format: Tape & Reel (TR) and Cut Tape (CT) formats are interchangeable for component procurement
• Series Designation: Different manufacturer series (M, V, MLAS, MSAR, MSAS, CC) are acceptable provided all electrical and mechanical parameters match

Substitute parts are grouped into two categories: Upgrade Parts (improved tolerance specifications) and Parametric Equivalents (matching tolerance specifications with different product status or manufacturer).

Engineering Selection Recommendations

For Legacy System Support: The TMK042CG3R3CD-W is classified as "Not For New Designs." When component availability becomes constrained, the following substitutes maintain full electrical and mechanical compatibility:

• MLAST042SCG3R3CWNA01 (Taiyo Yuden, Active Status): Identical electrical specifications with Active product status. Recommended for immediate replacement in production environments requiring long-term supply assurance.
• MSART042SCG3R3CWRA01 (Taiyo Yuden, Active Status): Equivalent specifications with Active status and Tape & Reel packaging.
• MSAST042SCG3R3CWNA01 (Taiyo Yuden, Active Status): Equivalent specifications with Active status and REACH Unaffected certification.
• CC0100CRNPO8BN3R3 (YAGEO, Active Status): Cross-manufacturer equivalent from YAGEO with identical electrical and mechanical parameters and Active product status.

For Improved Tolerance Requirements: When circuit design permits tighter tolerance specifications:

• TMK042CG3R3BD-W (Taiyo Yuden, ±0.1pF): Upgrade from ±0.25pF tolerance, same manufacturer series.
• TVS042CG3R3BC-W (Taiyo Yuden, ±0.1pF): Upgrade from ±0.25pF tolerance, optimized for RF and microwave applications.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical physical dimensions, ensuring direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG3R3BD-W replace TMK042CG3R3CD-W directly?

A: Yes. Both parts share identical capacitance (3.3 pF), voltage rating (25V), temperature coefficient (C0G, NP0), and package (01005). The TMK042CG3R3BD-W offers improved tolerance (±0.1pF versus ±0.25pF), making it a direct upgrade. Packaging format differs (Cut Tape versus Tape & Reel), but this does not affect component functionality.

Q: What is the difference between Taiyo Yuden series M, V, MLAS, MSAR, and MSAS?

A: Series designation indicates different product lines within Taiyo Yuden's portfolio. Series M and V are legacy lines (Not For New Designs). Series MLAS, MSAR, and MSAS are active product lines with identical electrical specifications. Selection between active series depends on application requirements (Medical for MLAS, General Purpose for MSAR and MSAS) and supply chain availability.

Q: Is CC0100CRNPO8BN3R3 from YAGEO compatible with the Taiyo Yuden original?

A: Yes. The YAGEO CC0100CRNPO8BN3R3 matches all critical electrical parameters (3.3 pF, 25V, C0G/NP0, ±0.25pF tolerance) and mechanical specifications (01005 package, -55°C to 125°C operating range). Cross-manufacturer substitution is valid when all parameters align.

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

A: No. Packaging format affects procurement and handling logistics only. Tape & Reel (TR) and Cut Tape (CT) formats contain identical components and perform identically once mounted on the circuit board.

Q: Why is TVS042CG3R3BC-W listed as optimized for RF and microwave applications?

A: TVS042CG3R3BC-W belongs to Taiyo Yuden's V series, which is characterized for high-frequency performance. However, all electrical and mechanical parameters remain identical to other 3.3 pF, 25V, C0G/NP0 01005 parts. Selection of this part is appropriate when RF/microwave performance characteristics are specified in the design.

Q: Can I use a substitute part with ±0.1pF tolerance in a circuit designed for ±0.25pF?

A: Yes. Tighter tolerance (±0.1pF) is a superset of looser tolerance (±0.25pF) requirements. Parts with ±0.1pF tolerance satisfy any circuit specification requiring ±0.25pF or wider tolerance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility.
