Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG180JWRA01 is determined by strict equivalence across the following parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 18 pF
• Tolerance: ±5%
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C to 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 substitute parts identified maintain full parametric equivalence across all electrical and mechanical specifications. Packaging format variations (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility and represent alternative supply configurations only.

Parameter Comparison

Engineering Selection Recommendations

MSART042SCG180JWRA01 (Primary Part)

The MSART042SCG180JWRA01 maintains Active product status and is the recommended selection for new designs. This part is supplied in Tape & Reel (TR) packaging format, which is standard for automated assembly operations. Active status indicates ongoing manufacturer support, continued availability, and compliance with current industry standards.

TMK042CG180JC-W (Substitute - Taiyo Yuden)

The TMK042CG180JC-W is electrically and mechanically equivalent to the primary part. However, this part carries "Not For New Designs" product status, indicating the manufacturer has discontinued active promotion for new applications. This part is supplied in Cut Tape (CT) packaging format, which may require alternative handling procedures in automated assembly environments. The TMK042CG180JC-W is suitable for legacy system support, repair, or rework applications where existing inventory exists.

KGM02ACG1E180JH (Substitute - KYOCERA AVX)

The KGM02ACG1E180JH is electrically and mechanically equivalent to the primary part and maintains Active product status. This part is supplied by KYOCERA AVX and is available in Tape & Reel (TR) packaging format, compatible with standard automated assembly processes. The KGM02ACG1E180JH provides an alternative qualified source from a different manufacturer, suitable for supply chain diversification or when primary manufacturer availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG180JC-W be used as a direct replacement for MSART042SCG180JWRA01?

A: The TMK042CG180JC-W is electrically and mechanically equivalent and can function as a direct replacement in the circuit. The primary difference is packaging format (Cut Tape versus Tape & Reel) and product status (Not For New Designs). Cut Tape packaging may require manual handling or alternative feeder compatibility in automated assembly. For new designs, the MSART042SCG180JWRA01 or KGM02ACG1E180JH are preferred.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically used for manual assembly or lower-volume applications. Both formats contain identical components; the difference is in supply configuration and handling requirements.

Q: Are all three parts suitable for high-reliability applications?

A: All three parts meet ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity requirements. The MSART042SCG180JWRA01 and KGM02ACG1E180JH maintain Active product status. The TMK042CG180JC-W carries "Not For New Designs" status, which may present considerations for long-term supply continuity in high-reliability applications.

Q: Can I mix manufacturers in the same assembly?

A: Yes. The MSART042SCG180JWRA01 (Taiyo Yuden) and KGM02ACG1E180JH (KYOCERA AVX) are electrically and mechanically equivalent and can be used interchangeably within the same assembly. Both maintain identical electrical performance, temperature characteristics, and physical dimensions.

Q: What does "Not For New Designs" mean for the TMK042CG180JC-W?

A: "Not For New Designs" indicates the manufacturer has transitioned this part to legacy status and is not actively promoting it for new applications. While the part remains functional and available, the manufacturer may reduce production capacity or eventually discontinue it. For new designs, select parts with Active status.

Q: Are there any thermal or frequency performance differences between these parts?

A: No. All three parts share identical temperature coefficient (C0G, NP0), operating temperature range (-55°C to 125°C), and capacitance value (18 pF). Performance in thermal cycling and frequency response applications is equivalent across all three parts.
