Substitute Part Grouping Explanation

Substitute parts for the TMK042CG910JC-W are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Capacitance: 91 pF
• Tolerance: ±5%
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 01005 (0402 Metric)
• Physical Dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Thickness (Max): 0.009" (0.22mm)
• Mounting Type: Surface Mount, MLCC

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts maintain identical electrical performance and physical form factor, with the primary distinction being packaging configuration (Cut Tape versus Tape & Reel) and product series designation. Both substitute parts are manufactured by Taiyo Yuden and carry Active product status, providing improved supply continuity compared to the legacy main part.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs Using TMK042CG910JC-W:

The TMK042CG910JC-W carries "Not For New Designs" status, indicating limited future availability. Both MLAST042SCG910JWNA01 and MSAST042SCG910JWNA01 are classified as Active products and provide direct electrical and mechanical equivalence. These substitutes are suitable for design continuity and supply chain optimization.

MLAST042SCG910JWNA01 Selection Criteria:

This substitute is designated for Medical and Non-Critical applications. It maintains identical electrical specifications and physical form factor while offering Tape & Reel packaging. ROHS3 compliance and REACH Unaffected status are confirmed. This part is appropriate for applications requiring medical-grade component traceability or non-critical application classifications.

MSAST042SCG910JWNA01 Selection Criteria:

This substitute is designated for General Purpose applications, matching the original part's application classification. It maintains identical electrical specifications and physical form factor while offering Tape & Reel packaging. ROHS3 compliance and REACH Unaffected status are confirmed. This part is appropriate for general-purpose circuit designs requiring continued supply of the 91 pF, 25V C0G/NP0 capacitor specification.

Packaging Consideration:

The primary distinction between the main part and substitutes is packaging configuration. TMK042CG910JC-W is supplied in Cut Tape format, while both substitutes are supplied in Tape & Reel format. This difference affects handling, storage, and automated assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can MLAST042SCG910JWNA01 and MSAST042SCG910JWNA01 be used interchangeably with TMK042CG910JC-W?

A: Yes. Both substitute parts maintain identical electrical parameters (91 pF, ±5%, 25V, C0G/NP0), operating temperature range (-55°C ~ 125°C), physical dimensions (0.016" L x 0.008" W, 0.009" max thickness), and compliance certifications (ROHS3, MSL 1). They are direct functional equivalents for circuit applications.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies components in individual strips, suitable for manual handling and small-quantity applications. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for automated pick-and-place assembly equipment. Both formats contain identical components; the difference is in supply and handling methodology.

Q: Are the substitute parts suitable for new design implementations?

A: MLAST042SCG910JWNA01 and MSAST042SCG910JWNA01 both carry Active product status, indicating they are suitable for new designs. The original TMK042CG910JC-W is marked "Not For New Designs," making the substitutes the recommended choice for new circuit implementations requiring this capacitor specification.

Q: Do the substitute parts have different moisture sensitivity requirements?

A: No. All three parts (main and substitutes) carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage, handling, or assembly.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 Compliant. The substitute parts additionally carry REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Q: Can these parts be used in medical applications?

A: MLAST042SCG910JWNA01 is specifically designated for Medical and Non-Critical applications. MSAST042SCG910JWNA01 is designated for General Purpose applications. Application suitability depends on specific medical device classification requirements and regulatory pathway requirements, which are determined by the end-use application rather than component designation alone.
