Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMK042CG7R3CD-W is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 7.3 pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Package / Case: 01005 (0402 Metric)
• 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)
• Operating Temperature Range: -55°C to 125°C
• Moisture Sensitivity Level: MSL 1

Allowable Variation Parameters:

• Tolerance: ±0.25 pF or tighter (±0.1 pF acceptable)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT)
• Product Status: Active or Not For New Designs
• Series Designation: M, MLAS, MSAR, MSAS

Substitute parts must maintain electrical equivalence across all mandatory parameters. Tolerance improvements and packaging format variations do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

TMK042CG7R3BD-W provides an upgrade path with improved tolerance specification (±0.1 pF versus ±0.25 pF). This part maintains identical electrical and mechanical characteristics while offering tighter capacitance control. Packaging is supplied in Cut Tape (CT) format rather than Tape & Reel. Product status remains "Not For New Designs."

MLAST042SCG7R3CWNA01 is an active product offering from the MLAS series with identical electrical specifications and Tape & Reel packaging. This part carries "Active" product status and is qualified for medical and non-critical applications. REACH Unaffected certification is provided.

MSART042SCG7R3CWRA01 is an active product from the MSAR series with identical electrical specifications and Tape & Reel packaging. This part carries "Active" product status and is designated for general purpose applications.

MSAST042SCG7R3CWNA01 is an active product from the MSAS series with identical electrical specifications and Tape & Reel packaging. This part carries "Active" product status and is designated for general purpose applications. REACH Unaffected certification is provided.

All substitute parts maintain full electrical and mechanical compatibility with the TMK042CG7R3CD-W. Selection among active alternatives should be based on application requirements, supply chain considerations, and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG7R3BD-W be used as a direct replacement for TMK042CG7R3CD-W?

A: Yes. Both parts share identical capacitance (7.3 pF), voltage rating (25V), temperature coefficient (C0G/NP0), package (01005), and operating temperature range (-55°C to 125°C). The TMK042CG7R3BD-W features improved tolerance (±0.1 pF) and is supplied in Cut Tape format rather than Tape & Reel.

Q: What is the difference between the active substitute parts (MLAST, MSART, MSAST) and the original TMK042CG7R3CD-W?

A: The active substitute parts (MLAST042SCG7R3CWNA01, MSART042SCG7R3CWRA01, MSAST042SCG7R3CWNA01) carry "Active" product status, indicating ongoing manufacturer support and availability. The original TMK042CG7R3CD-W is designated "Not For New Designs." All parts are electrically and mechanically equivalent with identical capacitance, voltage, temperature coefficient, and package specifications.

Q: Are there packaging format differences among the substitute parts?

A: Yes. TMK042CG7R3CD-W, MLAST042SCG7R3CWNA01, MSART042SCG7R3CWRA01, and MSAST042SCG7R3CWNA01 are supplied in Tape & Reel (TR) format. TMK042CG7R3BD-W is supplied in Cut Tape (CT) format. Both packaging formats are suitable for automated assembly processes; selection depends on production equipment and handling requirements.

Q: Does tolerance variation affect circuit performance?

A: Tolerance specifications define the acceptable capacitance range. TMK042CG7R3BD-W offers ±0.1 pF tolerance compared to ±0.25 pF for other parts. Both tolerances are within the same capacitance band and do not affect functional interchangeability in applications designed for 7.3 pF ±0.25 pF operation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (TMK042CG7R3BD-W, MLAST042SCG7R3CWNA01, MSART042SCG7R3CWRA01, MSAST042SCG7R3CWNA01) carry ROHS3 Compliant certification, matching the original TMK042CG7R3CD-W.

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

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

Q: Which substitute part should be selected for new production?

A: MLAST042SCG7R3CWNA01, MSART042SCG7R3CWRA01, and MSAST042SCG7R3CWNA01 all carry "Active" product status and are suitable for ongoing production. Selection among these three should be based on application requirements (medical/non-critical versus general purpose), supply chain availability, and internal qualification procedures.
