MSART042SCG120JWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG120JWRA01 is a 12 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is packaged in 01005 (0402 Metric) form factor and is supplied in Tape & Reel (TR) packaging. The part is currently Active in product status with 914 pieces in stock inventory.

Equivalent and substitute parts become necessary when primary part availability is limited, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSART042SCG120JWRA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 12 pF
• Tolerance: ±5%
• Voltage Rating: 25V
• Temperature Coefficient: C0G/NP0

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

Environmental & Compliance Parameters (Must Match):

• Operating Temperature Range: -55°C ~ 125°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

All identified substitute parts meet these parameters without exception. Packaging format (Tape & Reel versus Cut Tape) represents a secondary consideration for manufacturing logistics and does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The CC0100JRNPO8BN120 (YAGEO), KGM02ACG1E120JH (KYOCERA AVX), and KGU02ACG1E120JH (KYOCERA AVX) are all Active products with full compliance to ROHS3 and REACH standards. These parts are suitable for new designs and ongoing production. All three maintain identical electrical and mechanical specifications to the MSART042SCG120JWRA01.

Secondary Substitute (Not For New Designs):

The TMK042CG120JD-W (Taiyo Yuden) is designated as "Not For New Designs" and is supplied in Cut Tape (CT) packaging rather than Tape & Reel (TR). While electrically and mechanically equivalent, this part should be reserved for legacy system support or maintenance applications only. The Cut Tape format may require alternative handling procedures in automated assembly environments.

Packaging Consideration:

The MSART042SCG120JWRA01 is supplied in Tape & Reel (TR) format. The TMK042CG120JD-W is supplied in Cut Tape (CT) format. All other substitutes are supplied in Tape & Reel (TR) format, matching the original part's packaging specification.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG120JD-W be used as a direct replacement for MSART042SCG120JWRA01?

A: TMK042CG120JD-W is electrically and mechanically equivalent. However, it is designated "Not For New Designs" and supplied in Cut Tape (CT) packaging instead of Tape & Reel (TR). Use is limited to legacy applications or maintenance scenarios where automated reel-based assembly is not required.

Q: What is the difference between C0G and NPO temperature coefficient designations?

A: C0G and NPO are equivalent designations for the same temperature coefficient characteristic. C0G is the EIA standard designation, while NPO is the IEC standard designation. Both terms describe identical thermal stability performance across the -55°C ~ 125°C operating range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (MSART042SCG120JWRA01, TMK042CG120JD-W, CC0100JRNPO8BN120, KGM02ACG1E120JH, and KGU02ACG1E120JH) are ROHS3 Compliant.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only manufacturing logistics and assembly process compatibility. Electrical and mechanical performance is identical regardless of whether the part is supplied in Tape & Reel (TR) or Cut Tape (CT) format.

Q: Which substitute parts are recommended for new design implementations?

A: CC0100JRNPO8BN120, KGM02ACG1E120JH, and KGU02ACG1E120JH are all Active products suitable for new designs. The MSART042SCG120JWRA01 is also Active and remains the primary specification.

Q: What is Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without moisture control requirements. All identified parts carry MSL 1 rating, requiring no special storage or handling precautions related to moisture exposure.

Q: Can KGU02ACG1E120JH be used in general purpose applications?

A: Yes. While KGU02ACG1E120JH is specified for RF, Microwave, and High Frequency applications with High Q and Low Loss characteristics, it meets all electrical and mechanical parameters for general purpose use and is fully compatible with the MSART042SCG120JWRA01 specification.
