MSART042SCG5R9BWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG5R9BWRA01 is a 5.9 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V operation 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 in Active product status with 930 pieces available in stock.

Substitute parts become necessary when Tape & Reel packaging is unavailable, when alternative product lifecycle statuses are acceptable for specific applications, or when alternative packaging formats (Cut Tape) meet project requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSART042SCG5R9BWRA01 is permissible only when the replacement part maintains identical values across all critical electrical and mechanical parameters. The critical parameters that determine substitution eligibility are:

Capacitance value of 5.9 pF with tolerance of ±0.1pF, voltage rating of 25V, temperature coefficient classification of C0G/NP0, operating temperature range of -55°C to 125°C, package designation of 01005 (0402 Metric), surface-mount MLCC mounting type, physical dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm), maximum thickness of 0.009" (0.22mm), ROHS3 compliance, and MSL rating of 1 (Unlimited).

Variable parameters that do not affect substitution eligibility include packaging format (Tape & Reel versus Cut Tape) and product lifecycle status (Active versus Not For New Designs). These parameters may be selected based on procurement availability, inventory requirements, and design phase considerations.

Parameter Comparison

Engineering Selection Recommendations

The TMK042CG5R9BD-W is a parametric equivalent to the MSART042SCG5R9BWRA01 across all critical electrical and mechanical specifications. Both parts are manufactured by Taiyo Yuden and share identical capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, package type, physical dimensions, and compliance certifications.

The primary distinction between these parts is packaging format and product lifecycle status. The MSART042SCG5R9BWRA01 is supplied in Tape & Reel format and maintains Active product status, making it suitable for ongoing production and new design implementations. The TMK042CG5R9BD-W is supplied in Cut Tape format and carries Not For New Designs status, indicating it is available for legacy system support, repair applications, or situations where Cut Tape packaging meets procurement requirements.

Selection between these parts should be based on packaging format compatibility with assembly equipment and whether the application permits use of components with Not For New Designs status. Both parts satisfy identical electrical performance requirements and environmental compliance standards.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG5R9BD-W be used as a direct replacement for MSART042SCG5R9BWRA01 in new designs?

A: TMK042CG5R9BD-W is electrically and mechanically equivalent to MSART042SCG5R9BWRA01 across all critical parameters. However, TMK042CG5R9BD-W carries Not For New Designs status. Design teams must evaluate whether this lifecycle status is acceptable for their specific application requirements.

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

A: Tape & Reel packaging supplies components wound on continuous tape in reel format, suitable for automated pick-and-place assembly equipment. Cut Tape packaging supplies components on tape segments of specified lengths. Assembly equipment compatibility determines which packaging format is appropriate for a given production environment.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both MSART042SCG5R9BWRA01 and TMK042CG5R9BD-W are packaged in 01005 (0402 Metric) form factor with dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum thickness of 0.009" (0.22mm). They are mechanically interchangeable on printed circuit boards.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating unlimited shelf life under standard storage conditions. Both operate across the identical temperature range of -55°C to 125°C.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G and NP0 designations indicate zero temperature coefficient ceramic capacitors, meaning capacitance remains stable across the operating temperature range. This characteristic is critical for precision applications requiring stable capacitance values independent of temperature variations.

Q: Can inventory availability influence the substitution decision?

A: Inventory availability is a procurement consideration but does not affect electrical or mechanical equivalence. TMK042CG5R9BD-W has significantly higher inventory (40741 pieces) compared to MSART042SCG5R9BWRA01 (930 pieces). Procurement timelines and supply chain requirements may influence part selection when both are electrically equivalent.
