Würth Elektronik WE-FAS 32410 RF Ferrite Sheet Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 32410 is an RF EMI flexible ferrite sheet designed for electromagnetic interference suppression applications. This component features a square configuration measuring 7.874" × 7.874" × 0.043" with non-conductive, single-sided adhesive backing. The product is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives to maintain supply chain continuity for ongoing designs and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WE-FAS 32410 is determined by the following critical parameters:

• Material Composition: Rubber and ferrite powder construction ensures consistent electromagnetic absorption characteristics
• Adhesive Configuration: Non-conductive, single-sided adhesive maintains electrical isolation properties
• Thickness: 0.043" (1.10mm) thickness is the controlling dimension for EMI suppression performance
• Operating Temperature Range: -20°C ~ 90°C defines the thermal operating envelope
• Compliance Standards: ROHS3 compliance and REACH unaffected status are mandatory for regulatory alignment

The substitute part 32410S maintains identical material composition, adhesive type, thickness, temperature range, and compliance certifications. The primary difference is dimensional: the substitute provides a rectangular configuration (8.268" × 11.693") versus the original square format (7.874" × 7.874"). This dimensional variation allows the substitute to serve applications requiring larger coverage area while preserving the core electromagnetic and thermal performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The WE-FAS 32410S serves as the direct substitute for the discontinued WE-FAS 32410. Both components maintain identical material composition, thickness, adhesive configuration, and thermal operating specifications. The substitute part carries active product status, ensuring ongoing availability and supply chain reliability.

Selection of the 32410S is appropriate for applications where the rectangular geometry (8.268" × 11.693") accommodates the required EMI suppression coverage. The increased surface area of the substitute provides equivalent or enhanced electromagnetic absorption performance relative to the original square configuration, given the identical thickness and material properties.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements, supporting deployment in regulated industries and markets with environmental compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the WE-FAS 32410S directly replace the WE-FAS 32410 in existing designs?

A: The 32410S is functionally equivalent in electromagnetic performance, material composition, and thermal characteristics. Substitution is valid provided the rectangular dimensions (8.268" × 11.693") fit within the available mounting space. The original square format (7.874" × 7.874") cannot be directly replicated by the substitute geometry.

Q: What is the significance of the thickness specification in ferrite sheet selection?

A: Thickness directly determines electromagnetic absorption performance. Both the 32410 and 32410S maintain 0.043" (1.10mm) thickness, ensuring equivalent EMI suppression effectiveness across the operating frequency range.

Q: Are there packaging differences between the original and substitute parts?

A: The original 32410 is specified with "-" packaging notation, while the 32410S is supplied in Bag packaging. This represents a logistical difference with no impact on component performance or electrical characteristics.

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

A: Yes. Both the 32410 and 32410S are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements for environmental and hazardous substance restrictions.

Q: What is the operational temperature envelope for these ferrite sheets?

A: Both components operate within the -20°C ~ 90°C temperature range, defining the thermal limits for stable electromagnetic performance and material integrity.
