Z0402C221BPMST Ferrite Bead Equivalent & Substitute Parts

Part Overview

The Z0402C221BPMST is a 220 Ohm power line ferrite bead manufactured by KEMET in 0402 (1005 Metric) surface mount package. This component operates at 100 MHz impedance with a maximum DC resistance of 180 mOhm and supports operating temperatures from -55°C to 125°C. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain identical electrical performance characteristics and package specifications to ensure direct board-level compatibility.

Substitute Part Grouping Explanation

Substitution of the Z0402C221BPMST ferrite bead is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Impedance value of 220 Ohms at 100 MHz frequency
• Power line filter classification
• Single line configuration
• Operating temperature range of -55°C to 125°C

Mechanical Equivalence Criteria:

• 0402 (1005 Metric) package designation
• Surface mount mounting type
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Maximum height of 0.022" (0.55mm)

Compliance Equivalence Criteria:

• ROHS3 compliance
• MSL rating of 1 (Unlimited)
• REACH Unaffected status

The substitute part MPZ1005S221ET000 meets all electrical, mechanical, and compliance requirements for direct substitution. Variations in DC resistance (180 mOhm versus 220 mOhm) and current rating specifications do not preclude substitution when the primary impedance and frequency characteristics are identical.

Engineering Selection Recommendations

The MPZ1005S221ET000 (TDK Corporation) is the qualified substitute for the obsolete Z0402C221BPMST (KEMET). Selection of the TDK component is based on the following engineering factors:

Product Status Consideration: The Z0402C221BPMST is classified as obsolete, making the active MPZ1005S221ET000 the appropriate choice for new designs and production continuity.

Electrical Compatibility: Both components provide identical impedance characteristics (220 Ohms @ 100 MHz) and operate across the same temperature range (-55°C to 125°C), ensuring functional equivalence in power line filtering applications.

Mechanical Compatibility: Both parts utilize the 0402 (1005 Metric) surface mount package with identical physical dimensions and height specifications, enabling direct board-level substitution without layout modifications.

Compliance Alignment: Both components maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and REACH Unaffected status, satisfying regulatory and environmental requirements.

Packaging Availability: The MPZ1005S221ET000 is supplied in Tape & Reel (TR) format with significantly higher inventory availability (105,200 pieces), compared to the obsolete KEMET component.

Frequently Asked Questions (FAQ)

Q: Can the MPZ1005S221ET000 be used as a direct replacement for the Z0402C221BPMST on existing circuit boards?

A: Yes. Both components share identical impedance specifications (220 Ohms @ 100 MHz), package designation (0402/1005 Metric), physical dimensions, and operating temperature range. Direct substitution is supported at the board level without design modifications.

Q: What is the significance of the DC resistance difference between the two parts (180 mOhm versus 220 mOhm)?

A: The DC resistance values are secondary parameters that do not affect the primary impedance characteristic at 100 MHz. Both values fall within acceptable ranges for power line ferrite bead applications and do not preclude substitution.

Q: Are there packaging format differences between the two parts?

A: The Z0402C221BPMST is supplied in Cut Tape (CT) & Digi-Reel format, while the MPZ1005S221ET000 is supplied in Tape & Reel (TR) format. Both packaging formats are compatible with standard surface mount assembly equipment.

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

A: Yes. Both components are ROHS3 compliant, carry MSL rating 1 (Unlimited), and maintain REACH Unaffected status, satisfying identical regulatory requirements.

Q: What is the current rating specification for the substitute part?

A: The MPZ1005S221ET000 is rated for a maximum current of 900 mA. The original Z0402C221BPMST does not specify a current rating in the provided documentation.

Q: Is the TDK MPZ1005S221ET000 actively manufactured?

A: Yes. The MPZ1005S221ET000 is classified as an active product with substantial inventory availability (105,200 pieces), ensuring long-term supply continuity.
