ACML-0402-471-T Ferrite Bead Equivalent & Substitute Parts

Part Overview

The ACML-0402-471-T is a 470 Ohm ferrite bead manufactured by Abracon LLC in 0402 (1005 Metric) surface mount package. This component is designed for electromagnetic interference (EMI) suppression and signal line filtering in compact electronic assemblies. The part is currently in active production status with 997 pieces available in inventory. Equivalent and substitute parts may be required due to supply chain constraints, inventory availability, or specific application requirements where alternative impedance values or manufacturers are acceptable within design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACML-0402-471-T is determined by the following critical parameters:

Primary Substitution Criteria:

• Package / Case: 0402 (1005 Metric) surface mount form factor
• Current Rating (Max): 100mA minimum
• Operating Temperature Range: -55°C ~ 125°C minimum
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

• Impedance @ Frequency: 470 Ohms @ 100 MHz (exact match preferred; variations within ±10% acceptable for signal line applications)
• DC Resistance (DCR) (Max): 800mOhm or lower
• Height (Max): 0.026" (0.65mm) or lower for PCB assembly compatibility

Parts meeting all primary criteria and maintaining compatibility within secondary parameters are classified as direct or parametric equivalents. Impedance variations of ±10% are permissible when the substitute maintains the same functional purpose and electrical performance envelope.

Parameter Comparison

Engineering Selection Recommendations

ACML-0402-501-T (Abracon LLC): This substitute maintains identical mechanical and thermal specifications to the main part with a 500 Ohm impedance at 100 MHz, representing a 6.4% increase from the 470 Ohm specification. Both parts are manufactured by Abracon LLC within the same ACML series, share identical current ratings, DC resistance maximums, and operating temperature ranges. Both parts carry Active product status and ROHS3 compliance. This substitute is suitable for applications where impedance tolerance permits the specified variation. Inventory availability is significantly higher at 12,161 pieces.

7427927241 (Würth Elektronik): This substitute matches the exact 470 Ohm impedance specification at 100 MHz and provides superior DC resistance performance at 650mOhm maximum, compared to 800mOhm for the main part. The part maintains identical current rating, operating temperature range, and package dimensions. However, this part carries Obsolete product status and is supplied in Cut Tape (CT) & Digi-Reel® packaging rather than Tape & Reel format. ROHS3 compliance and MSL rating are equivalent. Selection of this substitute should account for its obsolete status and potential long-term supply constraints.

Frequently Asked Questions (FAQ)

Q: Can ACML-0402-501-T be used as a direct replacement for ACML-0402-471-T?

A: ACML-0402-501-T is a parametric equivalent suitable for substitution in applications where a 500 Ohm impedance at 100 MHz is acceptable. The 6.4% impedance increase falls within typical design tolerances for ferrite bead applications. All mechanical, thermal, and compliance specifications are identical. Verification of impedance tolerance requirements for your specific application is necessary before implementation.

Q: What is the difference between the Abracon and Würth Elektronik substitutes?

A: ACML-0402-501-T (Abracon) differs primarily in impedance value (500 Ohms vs. 470 Ohms) and maintains Active product status. The 7427927241 (Würth Elektronik) matches the 470 Ohm impedance exactly and offers lower DC resistance (650mOhm vs. 800mOhm), but carries Obsolete product status. Both share identical package dimensions, current ratings, and operating temperature ranges.

Q: Are there packaging format differences between these substitutes?

A: Yes. ACML-0402-471-T and ACML-0402-501-T are supplied in Tape & Reel (TR) format. The 7427927241 is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format may affect assembly line compatibility and handling procedures. Confirm packaging requirements with your manufacturing process before selection.

Q: Does the lower DC resistance of 7427927241 provide a performance advantage?

A: The 7427927241 provides 650mOhm maximum DC resistance compared to 800mOhm for the main part, representing an 18.75% reduction in resistive losses. This lower resistance may provide marginal performance benefits in power-sensitive applications. However, the Obsolete product status of this part presents supply chain risk that must be weighed against any performance advantage.

Q: Are all substitutes RoHS3 compliant?

A: Yes. ACML-0402-471-T, ACML-0402-501-T, and 7427927241 are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are REACH Unaffected and carry identical environmental compliance certifications.
