Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK042CG8R2CD-W is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 8.2 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
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant

Allowable Variation:

• Tolerance: Parts with ±0.1pF or ±0.25pF tolerance are functionally equivalent, as both fall within acceptable capacitance accuracy for general purpose applications
• Packaging Format: Tape & Reel (TR) and Cut Tape (CT) are interchangeable packaging methods for the same component specification
• Manufacturer: Multiple manufacturers produce equivalent specifications

Substitute parts are grouped into two categories: direct upgrades with improved tolerance specifications and parametric equivalents from alternative manufacturers or series lines.

Parameter Comparison

Engineering Selection Recommendations

Direct Upgrade Path: TMK042CG8R2BD-W represents a direct upgrade from TMK042CG8R2CD-W within the same Taiyo Yuden M series. This part maintains identical electrical specifications while offering improved tolerance (±0.1pF versus ±0.25pF). Both parts share "Not For New Designs" status. The primary distinction is packaging format: TMK042CG8R2BD-W is supplied in Cut Tape (CT) format rather than Tape & Reel (TR).

Active Product Alternatives: MLAST042SCG8R2CWNA01, MSAST042SCG8R2CWNA01, and CC0100CRNPO8BN8R2 are all designated as Active products, providing long-term availability assurance. These parts maintain full electrical and mechanical equivalence to the original TMK042CG8R2CD-W specification.

MLAST042SCG8R2CWNA01 (Taiyo Yuden MLAS series) and MSAST042SCG8R2CWNA01 (Taiyo Yuden MSAS series) are Taiyo Yuden manufactured alternatives with Active product status. MLAST042SCG8R2CWNA01 is specified for Medical and Non-Critical applications, while MSAST042SCG8R2CWNA01 is designated for General Purpose applications.

CC0100CRNPO8BN8R2 (YAGEO CC series) provides a cross-manufacturer equivalent with the highest inventory availability (40,557 pieces). This part maintains all critical electrical and mechanical parameters while offering supply chain diversification.

All substitute parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited) rating, matching the original component's environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG8R2BD-W be used as a direct replacement for TMK042CG8R2CD-W?

A: Yes. Both parts are electrically and mechanically equivalent. The primary difference is packaging format: TMK042CG8R2BD-W is supplied in Cut Tape (CT) while TMK042CG8R2CD-W is supplied in Tape & Reel (TR). The improved tolerance specification (±0.1pF) of TMK042CG8R2BD-W is compatible with applications designed for ±0.25pF tolerance.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the part is legacy or obsolescent. TMK042CG8R2CD-W and TMK042CG8R2BD-W retain this status. For new design work, MLAST042SCG8R2CWNA01, MSAST042SCG8R2CWNA01, or CC0100CRNPO8BN8R2 are recommended, as all three carry Active product status and provide long-term supply continuity.

Q: Are there differences in tolerance between substitute parts?

A: TMK042CG8R2BD-W offers ±0.1pF tolerance, while all other substitutes (MLAST042SCG8R2CWNA01, MSAST042SCG8R2CWNA01, and CC0100CRNPO8BN8R2) maintain ±0.25pF tolerance matching the original TMK042CG8R2CD-W. Both tolerance levels are functionally equivalent for general purpose applications.

Q: Can YAGEO CC0100CRNPO8BN8R2 replace Taiyo Yuden parts?

A: Yes. CC0100CRNPO8BN8R2 is a parametric equivalent meeting all electrical and mechanical specifications. It provides cross-manufacturer substitution with significantly higher inventory availability. All critical parameters including capacitance, voltage rating, temperature coefficient, package dimensions, and compliance certifications are identical.

Q: What are the packaging format differences between substitute parts?

A: TMK042CG8R2CD-W and MLAST042SCG8R2CWNA01, MSAST042SCG8R2CWNA01, and CC0100CRNPO8BN8R2 are supplied in Tape & Reel (TR) format. TMK042CG8R2BD-W is supplied in Cut Tape (CT) format. Both packaging methods are suitable for automated assembly; selection depends on production equipment compatibility and handling requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the environmental compliance of the original TMK042CG8R2CD-W.

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

A: All parts, including the original and all substitutes, carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
