MSART042SCG5R5BWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG5R5BWRA01 is a 5.5 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 classified as Active product status. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when alternative packaging formats are required for manufacturing processes while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MSART042SCG5R5BWRA01 is determined by strict equivalence across the following critical parameters:

Capacitance value must remain 5.5 pF with tolerance of ±0.1pF. Voltage rating must be 25V or higher. Temperature coefficient must be C0G/NP0 to ensure stable performance across the operating temperature range of -55°C to 125°C. Package and case designation must be 01005 (0402 Metric) with matching physical dimensions of 0.016" L x 0.008" W and maximum thickness of 0.009". Mounting type must be Surface Mount MLCC. RoHS3 compliance and MSL Level 1 rating must be maintained.

The primary distinction between the main part and its substitute relates to packaging format (Tape & Reel versus Cut Tape) and product status classification. These differences do not affect electrical performance or mechanical compatibility in the end application.

Parameter Comparison

Engineering Selection Recommendations

The MSART042SCG5R5BWRA01 is the preferred selection for new designs due to its Active product status classification. This designation indicates ongoing manufacturer support, continued availability, and compliance with current industry standards.

The TMK042CG5R5BD-W is electrically and mechanically equivalent and maintains full ROHS3 compliance and MSL Level 1 rating. However, this part carries a "Not For New Designs" status, indicating it is in a mature or transitional phase of its product lifecycle. Selection of this substitute is appropriate only when the primary part is unavailable or when existing inventory management strategies require alternative sourcing.

Both parts are manufactured by Taiyo Yuden and share identical electrical specifications, temperature performance characteristics, and physical dimensions. The distinction in packaging format (Tape & Reel versus Cut Tape) affects only the supply chain and assembly process, not the component's functional performance or end-use application.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG5R5BD-W be used as a direct replacement for MSART042SCG5R5BWRA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance value (5.5 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), package designation (01005/0402 Metric), and physical dimensions. Substitution does not require circuit redesign or board layout modification.

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 high-volume automated assembly processes. Cut Tape (CT) packaging provides components on shorter tape segments, typically used for lower-volume production or manual assembly. Both formats contain identical components; the difference is in supply format and handling during manufacturing.

Q: Why is TMK042CG5R5BD-W marked "Not For New Designs"?

A: This designation indicates the part is in a mature phase of its product lifecycle. While the component remains fully functional and compliant with all specifications, the manufacturer may have limited production capacity or plans for eventual discontinuation. For new product development, the Active-status MSART042SCG5R5BWRA01 is recommended to ensure long-term availability and supply chain stability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8532.24.0020. Compliance certifications are identical.

Q: Can these parts be used interchangeably in high-frequency or precision applications?

A: Yes. Both parts feature C0G/NP0 temperature coefficient, which provides stable capacitance across the full operating temperature range. This characteristic makes them suitable for applications requiring minimal capacitance drift, including RF circuits, precision timing networks, and temperature-sensitive analog circuits.

Q: What is the significance of the 01005 (0402 Metric) package size?

A: The 01005 designation refers to the imperial size code (0.01" x 0.005"), while 0402 Metric indicates the metric equivalent (0.4mm x 0.2mm). This is one of the smallest standard surface mount capacitor packages, used in space-constrained applications. Both parts use this identical package, ensuring mechanical compatibility with existing PCB designs and assembly equipment.
