TMK042CG7R2CD-W Equivalent & Substitute Parts

Part Overview

The TMK042CG7R2CD-W is a 7.2 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V operation with C0G/NP0 temperature coefficient characteristics. This component is packaged in 01005 (0402 Metric) form factor as a surface-mount multilayer ceramic capacitor (MLCC). The part carries a "Not For New Designs" product status, indicating that alternative components should be evaluated for new applications. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and transition to active product lines where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK042CG7R2CD-W is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 7.2 pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Package / Case: 01005 (0402 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Tolerance: Parts with ±0.1 pF or ±0.25 pF tolerance are interchangeable, as both fall within acceptable capacitance specifications for general-purpose applications
• Packaging Format: Tape & Reel (TR) and Cut Tape (CT) formats are mechanically and electrically equivalent; selection depends on assembly process requirements
• Product Status: Active product lines are preferred over "Not For New Designs" classifications for long-term supply assurance

Substitute parts are grouped into two categories: an upgrade option with tighter tolerance and parametric equivalents with active product status.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs (Direct Replacement): The TMK042CG7R2BD-W serves as a direct upgrade option. It maintains identical electrical specifications and physical form factor while offering improved tolerance (±0.1 pF versus ±0.25 pF). This tighter tolerance provides enhanced frequency stability in precision applications. Both parts carry "Not For New Designs" status; however, the upgrade option is suitable for sustaining production of existing designs.

For New Designs (Active Product Lines): MLAST042SCG7R2CWNA01 and MSAST042SCG7R2CWNA01 are recommended for new applications. Both parts carry Active product status, ensuring long-term availability and supply chain continuity. MLAST042SCG7R2CWNA01 is qualified for medical and non-critical applications, while MSAST042SCG7R2CWNA01 is designated for general-purpose use. Both maintain identical electrical and mechanical specifications to the main part, with ROHS3 compliance and unlimited moisture sensitivity rating.

Packaging Considerations: Selection between Tape & Reel (TR) and Cut Tape (CT) formats depends on assembly process requirements. TR packaging is standard for high-volume automated assembly, while CT is suitable for lower-volume or manual assembly operations.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG7R2BD-W replace TMK042CG7R2CD-W in existing designs?

A: Yes. TMK042CG7R2BD-W is electrically and mechanically equivalent with improved tolerance specification (±0.1 pF). The tighter tolerance provides enhanced performance in frequency-critical applications. Both parts are packaged in 01005 (0402 Metric) form factor and operate across the same temperature range (-55°C to 125°C).

Q: What is the difference between MLAST042SCG7R2CWNA01 and MSAST042SCG7R2CWNA01?

A: Both parts are parametrically identical with 7.2 pF capacitance, ±0.25 pF tolerance, and 25V rating. The primary difference is application classification: MLAST042SCG7R2CWNA01 is qualified for medical and non-critical applications, while MSAST042SCG7R2CWNA01 is designated for general-purpose use. Both carry Active product status and ROHS3 compliance.

Q: Why is product status important for component selection?

A: Product status indicates manufacturer support and supply continuity. "Not For New Designs" status signals that the manufacturer is phasing out the product line. Active status ensures long-term availability, ongoing manufacturing support, and stable pricing. For new designs, Active products are preferred to avoid obsolescence risk.

Q: Are Tape & Reel and Cut Tape formats interchangeable?

A: Yes, from an electrical and mechanical standpoint. Both formats contain identical components in 01005 (0402 Metric) package. Selection depends on assembly process: Tape & Reel is standard for automated high-volume production, while Cut Tape is used for lower-volume or manual assembly operations.

Q: Can these parts be used interchangeably in frequency-critical circuits?

A: TMK042CG7R2BD-W with ±0.1 pF tolerance is preferred for frequency-critical applications due to tighter capacitance specification. TMK042CG7R2CD-W, MLAST042SCG7R2CWNA01, and MSAST042SCG7R2CWNA01 with ±0.25 pF tolerance are suitable for general-purpose applications where capacitance variation within this range is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TMK042CG7R2CD-W, TMK042CG7R2BD-W, MLAST042SCG7R2CWNA01, and MSAST042SCG7R2CWNA01 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for commercial and industrial applications.
