Substitute Part Grouping Explanation

Substitution eligibility for the MSASE021SB5471MWNA01 is determined by strict equivalence across the following parameters:

Electrical Specifications:

Capacitance value: 470 pF
Tolerance: ±20%
Voltage rating: 16V
Temperature coefficient: X5R
Operating temperature range: -55°C to 85°C

Mechanical Specifications:

Package / Case designation: 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 & Environmental:

RoHS3 compliance
Moisture Sensitivity Level 1

Engineering Selection Recommendations

Primary Selection: MSASE021SB5471MWNA01

The MSASE021SB5471MWNA01 is the recommended choice for new circuit designs. This part carries Active product status, indicating ongoing manufacturer support, continued availability, and full design lifecycle commitment. It is supplied in Tape & Reel packaging, which is standard for automated assembly processes.

Alternative Selection: EMK021BJ471MK-W

The EMK021BJ471MK-W is a parametric equivalent that meets all electrical, mechanical, and compliance requirements. However, this part is designated as Not For New Designs, indicating it is in mature or end-of-life status. This substitute is suitable only for legacy system maintenance, repair, or replacement applications where the original part number is unavailable. The Cut Tape packaging format may require manual handling or alternative assembly processes compared to Tape & Reel format.

Both parts are ROHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard storage and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can EMK021BJ471MK-W be used as a direct replacement for MSASE021SB5471MWNA01 in new designs?

A: No. While EMK021BJ471MK-W is electrically and mechanically equivalent, it carries Not For New Designs status. New designs should specify MSASE021SB5471MWNA01, which has Active product status and 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 supplies the same components on shorter tape segments, typically requiring manual handling or alternative feeding mechanisms. Both formats contain identical components with identical electrical and mechanical specifications.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts use the 008004 (0201 Metric) package 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 PCBs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MSASE021SB5471MWNA01 and EMK021BJ471MK-W are ROHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). They meet identical environmental and regulatory requirements.

Q: What applications are these capacitors designed for?

A: Both parts are specified for SMPS (Switched-Mode Power Supply) filtering applications, where their 470 pF capacitance, 16V rating, and X5R temperature coefficient provide stable performance across the -55°C to 85°C operating range.

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

A: Substitution from MSASE021SB5471MWNA01 to EMK021BJ471MK-W requires evaluation of packaging compatibility with existing assembly equipment. The Cut Tape format of EMK021BJ471MK-W may not be compatible with automated Tape & Reel feeders. Substitution in the reverse direction (EMK021BJ471MK-W to MSASE021SB5471MWNA01) is recommended for new production runs.
