MSART042SCG1R8AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG1R8AWRA01 is a 1.8 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 maintains an Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and packaging compatibility. These alternatives provide design flexibility for procurement, inventory management, and supply chain continuity while maintaining identical functional performance in circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the MSART042SCG1R8AWRA01 are qualified based on the following criteria:

Electrical Parameters (Critical for Substitution):

• Capacitance value: 1.8 pF
• Capacitance tolerance: ±0.05pF
• Voltage rating: 25V (minimum)
• Temperature coefficient: C0G/NP0 (zero temperature coefficient)
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters (Critical for Substitution):

• Package type: 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:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts identified in this reference maintain identical electrical and mechanical specifications. Packaging format (Tape & Reel versus Cut Tape) represents a logistics variation that does not affect functional equivalence or circuit performance.

Engineering Selection Recommendations

Primary Selection: MSART042SCG1R8AWRA01

The MSART042SCG1R8AWRA01 maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. This part is suitable for new designs and ongoing production applications. Tape & Reel packaging supports automated assembly processes.

Secondary Selection: CQ0100ARNPO8BN1R8

The CQ0100ARNPO8BN1R8 (YAGEO manufacturer) is an Active product with identical electrical and mechanical specifications. This part provides cross-manufacturer equivalence and is suitable for new designs. Tape & Reel packaging format matches the primary part. High Q feature designation indicates superior performance characteristics in specific applications.

Alternative Selection: TMK042CG1R8AD-W

The TMK042CG1R8AD-W (Taiyo Yuden manufacturer) carries a "Not For New Designs" product status designation. This part maintains full electrical and mechanical equivalence but is intended for legacy system support and replacement applications only. Cut Tape packaging format requires manual handling or reel conversion for automated assembly processes.

Selection between active products (MSART042SCG1R8AWRA01 and CQ0100ARNPO8BN1R8) is determined by manufacturer preference, supply availability, and procurement lead times. The "Not For New Designs" part should be reserved for maintenance and repair of existing systems.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG1R8AD-W be used as a direct replacement for MSART042SCG1R8AWRA01?

A: Yes, TMK042CG1R8AD-W provides direct electrical and mechanical equivalence. However, the "Not For New Designs" status indicates this part is intended for legacy applications. For new circuit designs, select from active products: MSART042SCG1R8AWRA01 or CQ0100ARNPO8BN1R8.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, requiring manual handling or reel conversion. Both formats contain identical components with no functional difference.

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

A: All three parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Selection for high-reliability applications depends on product status: MSART042SCG1R8AWRA01 and CQ0100ARNPO8BN1R8 are Active products suitable for critical applications. TMK042CG1R8AD-W is restricted to legacy system support.

Q: Does the CQ0100ARNPO8BN1R8 "High Q" feature affect substitution compatibility?

A: The High Q feature indicates superior performance characteristics but does not affect basic substitution compatibility. All three parts meet the specified 1.8 pF capacitance, 25V voltage rating, and C0G/NP0 temperature coefficient requirements. The High Q designation represents an additional performance attribute of the YAGEO part.

Q: Can these parts be used interchangeably in automated assembly?

A: MSART042SCG1R8AWRA01 and CQ0100ARNPO8BN1R8 are both supplied in Tape & Reel format and are directly compatible with standard automated pick-and-place equipment. TMK042CG1R8AD-W in Cut Tape format requires manual handling or reel conversion before automated assembly.

Q: What compliance certifications apply to all substitute parts?

A: All three parts maintain ROHS3 compliance and carry EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
