Z0201C220ASMST Ferrite Bead Equivalent & Substitute Parts

Part Overview

The Z0201C220ASMST is a 22 Ohm ferrite bead manufactured by KEMET, designed for signal line filtering applications in 0201 (0603 Metric) surface mount packages. This component operates at 100 MHz impedance with a maximum current rating of 500mA and DC resistance of 100mOhm. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical performance characteristics while offering current availability and active product status.

Substitute Part Grouping Explanation

Substitution of the Z0201C220ASMST is determined by the following critical parameters:

Electrical Compatibility:

• Impedance value of 22 Ohms at 100 MHz must be maintained
• Operating temperature range of -55°C to 125°C must be supported
• Package and case designation of 0201 (0603 Metric) must match
• Surface mount mounting type must be preserved

Performance Considerations:

• Current rating must equal or exceed 500mA
• DC resistance must not exceed 100mOhm
• Single signal line configuration (1 Line) must be maintained

Regulatory & Compliance:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required
• REACH Unaffected status required

The BLM03PG220SN1D from Murata Electronics satisfies all substitution criteria with enhanced electrical performance characteristics.

Engineering Selection Recommendations

The BLM03PG220SN1D from Murata Electronics is the qualified substitute for the obsolete Z0201C220ASMST. Selection is based on the following engineering criteria:

Electrical Performance: The substitute part maintains identical impedance characteristics at 100 MHz while providing superior current handling capacity (900mA versus 500mA) and lower DC resistance (65mOhm versus 100mOhm). These enhanced specifications ensure the substitute operates within acceptable thermal and electrical margins in the application circuit.

Physical Compatibility: Both parts share identical package dimensions, height specifications, and surface mount configuration, ensuring direct PCB layout compatibility without redesign requirements.

Regulatory Compliance: The substitute part maintains full RoHS3 compliance, MSL 1 rating, and REACH Unaffected status, satisfying all regulatory requirements of the original component.

Product Availability: The substitute part carries active product status with substantial inventory availability (20,200 pieces), eliminating supply chain risk associated with the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the BLM03PG220SN1D directly replace the Z0201C220ASMST without circuit modification?

A: Yes. The substitute part maintains identical electrical impedance at 100 MHz, operating temperature range, and physical package dimensions. Direct PCB substitution is supported without circuit redesign.

Q: What is the significance of the higher current rating in the substitute part?

A: The BLM03PG220SN1D supports 900mA maximum current compared to 500mA in the original part. This enhanced rating provides additional design margin and thermal performance in the application circuit. The substitute part operates at lower DC resistance (65mOhm versus 100mOhm), reducing power dissipation.

Q: Are there differences in filter type between the original and substitute parts?

A: The original Z0201C220ASMST is specified as a signal line ferrite bead, while the BLM03PG220SN1D is specified as a power line ferrite bead. Both parts maintain the same electrical impedance and frequency characteristics required for the application. The filter type designation reflects the intended application category rather than fundamental electrical incompatibility.

Q: Does the substitute part meet all compliance requirements of the original?

A: Yes. The BLM03PG220SN1D maintains RoHS3 compliance, MSL 1 (Unlimited) rating, and REACH Unaffected status identical to the original Z0201C220ASMST.

Q: What is the packaging format of the substitute part?

A: The BLM03PG220SN1D is supplied in Tape & Reel (TR) format, standard for high-volume surface mount component distribution.

Q: Are there any thermal or electrical performance differences that would affect circuit operation?

A: The substitute part provides improved thermal performance through lower DC resistance. Both parts operate across the identical temperature range of -55°C to 125°C. The enhanced current rating and reduced resistance of the substitute part result in lower power dissipation and improved reliability margins.
