MSAST042SCG5R2BWNA01 Equivalent & Substitute Parts

Part Overview

The MSAST042SCG5R2BWNA01 is a 5.2 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 in Active product status with 1015 pieces available in stock.

Substitute parts become necessary when Tape & Reel packaging is unavailable, when inventory constraints require alternative sourcing, or when design revisions permit the use of parts with equivalent electrical and mechanical specifications but different packaging formats or product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSAST042SCG5R2BWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 5.2 pF
• Tolerance: ±0.1pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 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 (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape) and product lifecycle status without affecting functional equivalence in circuit applications.

Engineering Selection Recommendations

MSAST042SCG5R2BWNA01 (Primary Selection): This part is the recommended choice for new designs. It maintains Active product status with Taiyo Yuden, ensuring long-term availability and manufacturing consistency. The Tape & Reel packaging format is optimized for automated assembly processes. Current inventory of 1015 pieces supports production requirements. Full ROHS3 compliance and MSL 1 rating confirm suitability for standard manufacturing and storage conditions.

TMK042CG5R2BD-W (Alternative Selection): This substitute part provides electrical and mechanical equivalence with identical capacitance, voltage rating, temperature coefficient, and physical dimensions. However, it carries "Not For New Designs" product status, indicating Taiyo Yuden has discontinued active development and support for this part number. The Cut Tape packaging format requires manual handling or alternative assembly equipment compared to Tape & Reel format. This part is suitable for legacy design maintenance, repair operations, or applications where existing inventory must be utilized. The significantly higher available inventory (41045 pieces) may support short-term sourcing needs when primary part availability is constrained.

Both parts maintain identical compliance certifications (ROHS3, MSL 1) and operate within the same temperature range (-55°C ~ 125°C), ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG5R2BD-W be used as a direct replacement for MSAST042SCG5R2BWNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical capacitance (5.2 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), and physical dimensions (01005/0402 Metric). The primary difference is packaging format (Cut Tape versus Tape & Reel) and product lifecycle status.

Q: What is the significance of "Not For New Designs" status on the TMK042CG5R2BD-W?

A: This designation indicates that Taiyo Yuden has classified this part as obsolete or end-of-life for new product development. While the part remains functionally equivalent and available in inventory, it should not be selected for new designs. It is appropriate for legacy product support, repair operations, or temporary sourcing when the primary part is unavailable.

Q: Are there packaging compatibility issues between Tape & Reel and Cut Tape formats?

A: Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment and provides continuous component supply on carrier tape. Cut Tape (CT) packaging requires manual handling or alternative feeding mechanisms. If your assembly process uses automated equipment configured for Tape & Reel format, substitution with Cut Tape packaging requires process modification or manual component placement.

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

A: Yes. Both MSAST042SCG5R2BWNA01 and TMK042CG5R2BD-W are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Both operate across the identical temperature range of -55°C to 125°C.

Q: What is the difference in available inventory between these parts?

A: MSAST042SCG5R2BWNA01 has 1015 pieces in stock, while TMK042CG5R2BD-W has 41045 pieces available. The significantly higher inventory of the substitute part may be relevant for high-volume production runs or when primary part availability is limited.

Q: Are the electrical characteristics identical between these two parts?

A: Yes. Both parts have identical capacitance (5.2 pF), tolerance (±0.1pF), voltage rating (25V), and temperature coefficient (C0G/NP0). They are parametrically equivalent and will perform identically in circuit applications.
