Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSART042SCG0R9AWRA01 is determined by strict equivalence across the following parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 0.9 pF
• Tolerance: ±0.05pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

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

Compliance Parameters (Must Match):

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

Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape) and product status classification, provided all electrical, mechanical, and compliance parameters remain identical. Packaging format differences do not affect component functionality or circuit performance.

Parameter Comparison

Engineering Selection Recommendations

MSART042SCG0R9AWRA01 (Primary Selection)

The MSART042SCG0R9AWRA01 maintains Active product status and is the recommended selection for new designs. This part is supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly processes. Current inventory of 756 pieces supports immediate procurement requirements.

TMK042CG0R9AD-W (Secondary Selection)

The TMK042CG0R9AD-W is electrically and mechanically equivalent to the main part. However, this part carries a "Not For New Designs" product status designation, indicating that Taiyo Yuden has classified it as obsolescent. This part is supplied in Cut Tape (CT) packaging format, which may require manual handling or alternative assembly processes. Use of this part is limited to legacy design support or situations where existing inventory must be consumed. Significantly higher inventory availability (30579 pieces) may support extended production runs for existing products.

CQ0100ARNPO8BNR90 (Alternative Selection)

The CQ0100ARNPO8BNR90 is manufactured by YAGEO and maintains Active product status. All electrical specifications, mechanical dimensions, and compliance certifications are identical to the main part. This part is supplied in Tape & Reel (TR) packaging, compatible with standard surface mount assembly equipment. The CQ0100ARNPO8BNR90 is suitable for new designs when multi-source component strategies are required or when Taiyo Yuden supply becomes constrained. Inventory of 12193 pieces supports production requirements.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG0R9AD-W be used as a direct replacement for MSART042SCG0R9AWRA01?

A: Yes. The TMK042CG0R9AD-W is electrically and mechanically equivalent. All critical parameters including capacitance, voltage rating, temperature coefficient, package dimensions, and compliance certifications are identical. The primary difference is packaging format (Cut Tape versus Tape & Reel) and product status classification. Cut Tape packaging may require process modifications in automated assembly environments.

Q: What is the significance of the "Not For New Designs" status on TMK042CG0R9AD-W?

A: This designation indicates that Taiyo Yuden has classified the part as obsolescent for new product development. The part remains functionally equivalent and available in inventory, but manufacturers typically recommend using Active status parts for new designs to ensure long-term supply continuity and avoid future obsolescence issues.

Q: Are there differences in performance between the Taiyo Yuden and YAGEO versions?

A: No performance differences exist between MSART042SCG0R9AWRA01, TMK042CG0R9AD-W, and CQ0100ARNPO8BNR90. All three parts meet identical electrical specifications, temperature coefficients, and operating ranges. The CQ0100ARNPO8BNR90 includes a "High Q" feature designation, which indicates superior quality factor characteristics but does not alter the fundamental electrical performance for this capacitance value.

Q: Does packaging format affect circuit performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats contain identical components. Packaging format differences affect only the handling and assembly process. Tape & Reel is standard for high-volume automated assembly, while Cut Tape may be used for lower-volume or manual assembly operations.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All three parts are direct substitutes for the MSART042SCG0R9AWRA01. Electrical performance, mechanical fit, and compliance certifications are identical. No circuit modifications or re-qualification testing is required when substituting between these parts.

Q: What is the Moisture Sensitivity Level (MSL) rating and why is it important?

A: All three parts carry MSL 1 (Unlimited) rating, indicating that these components have unlimited shelf life and require no special moisture control handling. This classification simplifies storage, transportation, and assembly processes compared to higher MSL rated components.

Q: Are all three parts RoHS compliant?

A: Yes. MSART042SCG0R9AWRA01, TMK042CG0R9AD-W, and CQ0100ARNPO8BNR90 are all ROHS3 Compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
