Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMK042CG070CD-W is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 7 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)

Allowable Variation:

• Tolerance: ±0.25pF or tighter (±0.1pF acceptable)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT)
• Product Status: Active or Not For New Designs
• Manufacturer: Taiyo Yuden or KYOCERA AVX

All identified substitute parts maintain identical electrical performance specifications and physical form factors, ensuring direct compatibility in existing designs.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs (Maintenance & Repair): The TMK042CG070BD-W (Taiyo Yuden) serves as the direct upgrade path within the same manufacturer's product line. This part maintains identical electrical specifications with improved tolerance (±0.1pF versus ±0.25pF) and is available in Cut Tape format. Both parts retain "Not For New Designs" status but offer equivalent performance.

For New Designs: MLAST042SCG070CWNA01 and MSAST042SCG070CWNA01 (Taiyo Yuden, Active status) are recommended as primary alternatives. Both parts carry Active product status, ensuring long-term availability and supply chain stability. These components maintain identical electrical and physical specifications to the original part.

For Cross-Manufacturer Substitution: KGM02ACG1E7R0CH and KGU02ACG1E7R0CH (KYOCERA AVX, Active status) provide equivalent performance with established availability. KGU02ACG1E7R0CH is specified for RF, Microwave, and High Frequency applications with High Q and Low Loss characteristics. All KYOCERA AVX alternatives carry Active product status and ROHS3 compliance.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with existing manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG070BD-W replace TMK042CG070CD-W in existing designs? A: Yes. Both parts are manufactured by Taiyo Yuden with identical capacitance (7 pF), voltage rating (25V), temperature coefficient (C0G/NP0), and package (01005). The TMK042CG070BD-W features tighter tolerance (±0.1pF) and is available in Cut Tape format instead of Tape & Reel.

Q: What is the difference between MLAST042SCG070CWNA01 and MSAST042SCG070CWNA01? A: Both parts are manufactured by Taiyo Yuden with identical electrical specifications (7 pF, ±0.25pF, 25V, C0G/NP0) and package format (01005, Tape & Reel). The primary difference is the product series designation (MLAS versus MSAS). Both carry Active product status.

Q: Are KYOCERA AVX parts suitable for general purpose applications? A: Yes. KGM02ACG1E7R0CH is specified for General Purpose applications. KGU02ACG1E7R0CH is optimized for RF, Microwave, and High Frequency applications with High Q and Low Loss characteristics. Both parts meet the electrical requirements of the original TMK042CG070CD-W.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Cut Tape (CT) formats contain identical components and deliver equivalent electrical performance. Format selection is determined by manufacturing and assembly requirements.

Q: Are all substitute parts RoHS compliant? A: Yes. All identified substitute parts carry ROHS3 compliance status, matching the original TMK042CG070CD-W.

Q: What does "Not For New Designs" status mean? A: This designation indicates the manufacturer is not recommending the part for new product development. However, the part remains available for existing designs and maintenance applications. For new designs, MLAST042SCG070CWNA01, MSAST042SCG070CWNA01, KGM02ACG1E7R0CH, and KGU02ACG1E7R0CH carry Active status and are suitable for new applications.

Q: Can I mix substitute parts from different manufacturers in the same design? A: Yes. All substitute parts maintain identical electrical specifications, physical dimensions, and compliance certifications. Cross-manufacturer substitution is electrically and mechanically compatible.
