MSASE021SB5221MWNA01 Equivalent & Substitute Parts

Part Overview

The MSASE021SB5221MWNA01 is a 220 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 16V operation with X5R temperature coefficient characteristics. This multilayer ceramic capacitor (MLCC) is designed for surface mount applications in SMPS filtering circuits. The component is supplied in 0201 metric package format (008004) with Tape & Reel packaging.

The part is currently in Active product status. Substitute parts are identified for applications requiring alternative packaging formats or inventory sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MSASE021SB5221MWNA01 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 220 pF
• Tolerance: ±20%
• Voltage rating: 16V
• Temperature coefficient: X5R
• Operating temperature range: -55°C to 85°C

Mechanical Equivalence Criteria:

• Package type: 008004 (0201 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.010" L x 0.005" W (0.25mm x 0.13mm)
• Maximum thickness: 0.005" (0.14mm)

Compliance Equivalence Criteria:

• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must satisfy all three equivalence categories. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility and represent alternative supply chain options.

Engineering Selection Recommendations

MSASE021SB5221MWNA01 (Primary Selection)

The MSASE021SB5221MWNA01 is the recommended selection for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. It is supplied in Tape & Reel packaging, which is standard for automated assembly processes. The component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

EMK021BJ221MK-W (Substitute Selection)

The EMK021BJ221MK-W is electrically and mechanically equivalent to the primary part. This substitute is suitable for applications where Cut Tape packaging is acceptable or preferred for manual assembly or lower-volume production. However, this part carries "Not For New Designs" status, indicating the manufacturer has discontinued active development. This part is appropriate for legacy system maintenance, repair, or replacement applications where the original specification must be maintained.

Both parts are manufactured by Taiyo Yuden and satisfy all electrical, mechanical, and compliance requirements for SMPS filtering applications in 0201 metric package format.

Frequently Asked Questions (FAQ)

Q: Can EMK021BJ221MK-W be used as a direct replacement for MSASE021SB5221MWNA01 in new product designs?

A: EMK021BJ221MK-W is electrically and mechanically equivalent and meets all compliance requirements. However, it carries "Not For New Designs" status. For new designs, MSASE021SB5221MWNA01 is the appropriate selection due to its Active product status and ongoing manufacturer support.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on cut segments of carrier tape, typically used for manual assembly or lower-volume applications. Both packaging formats contain identical components with identical electrical and mechanical specifications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are 0201 metric package format (008004) with dimensions of 0.010" L x 0.005" W (0.25mm x 0.13mm) and maximum thickness of 0.005" (0.14mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet current regulatory compliance?

A: Yes. Both MSASE021SB5221MWNA01 and EMK021BJ221MK-W are ROHS3 compliant and REACH unaffected. Both carry Moisture Sensitivity Level 1 (Unlimited), requiring no special handling during storage or assembly.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across -55°C to 85°C with X5R temperature coefficient, providing stable capacitance performance across this temperature range for SMPS filtering applications.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided the PCB assembly process can accommodate the packaging format supplied. If the assembly line is configured for Tape & Reel input, EMK021BJ221MK-W (Cut Tape) would require manual feeding or reeling. Conversely, if manual assembly is used, Cut Tape format is more practical than Tape & Reel.
