Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK042CG3R6CD-W is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 3.6 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 functionally equivalent, as both fall within acceptable capacitance specifications for general purpose applications
• Packaging Format: Tape & Reel (TR) and Cut Tape (CT) are interchangeable packaging options for the same component
• Product Status: Active status parts are preferred over "Not For New Designs" status for new implementations
• Series Designation: Different series (M, MLAS, MSAS) represent product line variations with identical electrical specifications

Substitute parts listed below meet all mandatory parameters and are therefore direct electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs (Maintenance and Repair): The TMK042CG3R6CD-W remains functionally equivalent to TMK042CG3R6BD-W. Both parts share identical electrical specifications and mechanical form factors. Selection between these two depends on packaging requirements: TMK042CG3R6CD-W is supplied in Tape & Reel format, while TMK042CG3R6BD-W is supplied in Cut Tape format. Both maintain ROHS3 compliance and MSL 1 rating.

For New Designs: MLAST042SCG3R6CWNA01 and MSAST042SCG3R6CWNA01 are recommended as primary selections due to their Active product status. Both parts provide identical electrical performance to the original TMK042CG3R6CD-W while offering long-term design support and availability. MLAST042SCG3R6CWNA01 is designated for medical and non-critical applications, while MSAST042SCG3R6CWNA01 is designated for general purpose applications. Selection between these two should align with the intended application category.

Tolerance Consideration: TMK042CG3R6BD-W offers improved tolerance specification (±0.1 pF versus ±0.25 pF). This tighter tolerance may be selected when circuit performance requires reduced capacitance variation, provided that packaging format (Cut Tape) is compatible with assembly processes.

All listed substitutes maintain full electrical and mechanical compatibility with the original part specification.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG3R6BD-W be used as a direct replacement for TMK042CG3R6CD-W?

A: Yes. Both parts are electrically and mechanically equivalent, sharing identical capacitance, voltage rating, temperature coefficient, package dimensions, and operating temperature range. The primary difference is packaging format: TMK042CG3R6CD-W uses Tape & Reel while TMK042CG3R6BD-W uses Cut Tape. Tolerance specification differs (±0.1 pF versus ±0.25 pF), with TMK042CG3R6BD-W providing tighter tolerance.

Q: What is the difference between MLAST042SCG3R6CWNA01 and MSAST042SCG3R6CWNA01?

A: Both parts are electrically identical with matching capacitance, voltage, temperature coefficient, and package specifications. The primary distinction is application designation: MLAST042SCG3R6CWNA01 is specified for medical and non-critical applications, while MSAST042SCG3R6CWNA01 is designated for general purpose applications. Both carry Active product status.

Q: Why is product status important when selecting a substitute?

A: Product status indicates manufacturer support and long-term availability. Parts marked "Not For New Designs" may have limited future availability and reduced design support. Active status parts (MLAST042SCG3R6CWNA01 and MSAST042SCG3R6CWNA01) are recommended for new circuit implementations to ensure sustained component supply and technical support.

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

A: Both formats contain identical components and are electrically equivalent. Packaging format selection depends on assembly process requirements. Tape & Reel format is suitable for automated pick-and-place assembly, while Cut Tape format is used for manual or semi-automated assembly processes.

Q: Does tolerance specification affect component substitution?

A: Tolerance specification defines the acceptable range of capacitance variation. TMK042CG3R6CD-W and MLAST042SCG3R6CWNA01 and MSAST042SCG3R6CWNA01 all specify ±0.25 pF tolerance, while TMK042CG3R6BD-W specifies ±0.1 pF. Tighter tolerance (±0.1 pF) provides reduced capacitance variation and may be selected when circuit performance requires higher precision. All three tolerance specifications are compatible with general purpose applications.

Q: Are all listed parts RoHS compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original TMK042CG3R6CD-W specification.

Q: What does Moisture Sensitivity Level 1 indicate?

A: MSL 1 indicates unlimited moisture sensitivity, meaning the component requires no special moisture control during storage, handling, or assembly. All listed parts carry MSL 1 rating.
