KEMET Z0201C100CSMST Ferrite Bead Equivalent & Substitute Parts

Part Overview

The KEMET Z0201C100CSMST is a single-line signal ferrite bead in 0201 (0603 Metric) surface mount package, rated at 10 Ohms impedance at 100 MHz with a maximum current rating of 200mA and 400mOhm DC resistance. This component is classified as obsolete product status. Due to its obsolete designation, identifying active equivalent and substitute parts is necessary to maintain design continuity and ensure ongoing component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KEMET Z0201C100CSMST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Impedance @ Frequency: 10 Ohms @ 100 MHz
• Filter Type: Signal Line
• Number of Lines: 1
• Package / Case: 0201 (0603 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 125°C
• DC Resistance (DCR) (Max): 400mOhm

Allowable Variation Parameters:

• Current Rating (Max): Substitute parts may exceed the original 200mA specification, provided the maximum rating is not lower
• Product Status: Active substitute parts are preferred over obsolete originals

The identified substitute parts meet all mandatory matching parameters. Both substitute parts feature identical impedance characteristics, package dimensions, and thermal operating range. The substitute parts provide equal or superior current handling capability compared to the original specification.

Engineering Selection Recommendations

Primary Substitute: Murata Electronics BLM03BB100SN1D

The Murata Electronics BLM03BB100SN1D is the recommended substitute for the obsolete KEMET Z0201C100CSMST. This part maintains full electrical and mechanical equivalence across all critical parameters while offering active product status. The BLM03BB100SN1D is part of the EMIFIL® series and provides superior inventory availability (89,188 pieces in stock). All compliance certifications match the original specification, including ROHS3 compliance, REACH unaffected status, and MSL 1 rating.

Secondary Substitute: Pulse Electronics BBNQ00060303100Y00

The Pulse Electronics BBNQ00060303100Y00 provides an alternative substitute option with identical electrical characteristics and mechanical compatibility. This part is supplied in Tape & Reel packaging and maintains active product status. Current rating capability is increased to 300mA, providing additional design margin. Compliance certifications are equivalent to the original part.

Both substitute parts are suitable for direct replacement in applications requiring the KEMET Z0201C100CSMST specification. Selection between the two substitutes may be based on packaging preference, supplier availability, or lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can the Pulse Electronics BBNQ00060303100Y00 or Murata Electronics BLM03BB100SN1D be used as direct replacements for the KEMET Z0201C100CSMST?

A: Yes. Both substitute parts meet all mandatory electrical and mechanical parameters. Impedance, DC resistance, package dimensions, and operating temperature range are identical. The substitute parts are electrically and mechanically compatible for direct board-level substitution.

Q: What is the significance of the higher current rating (300mA) in the substitute parts compared to the original 200mA specification?

A: The higher current rating in the substitute parts indicates increased current handling capability. This represents an enhancement over the original specification and does not create compatibility issues. Designs operating within the original 200mA specification will function within the substitute parts' rated parameters.

Q: Are there packaging differences between the substitute parts?

A: The Pulse Electronics BBNQ00060303100Y00 is supplied in Tape & Reel (TR) packaging. The Murata Electronics BLM03BB100SN1D is also supplied in Tape & Reel (TR) packaging. Both packaging formats are standard for surface mount production environments. Physical package dimensions and mounting characteristics are identical across all three parts.

Q: Do the substitute parts maintain the same compliance certifications as the original KEMET part?

A: Yes. Both substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original KEMET Z0201C100CSMST specifications.

Q: Why is the KEMET Z0201C100CSMST classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The substitute parts listed are active products from alternative manufacturers that provide equivalent functionality and specifications.

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

A: Yes. The substitute parts maintain identical impedance characteristics at 100 MHz, DC resistance, package form factor, and thermal operating range. No design modifications are required for substitution.
