Key Parameters

Substitute Part Grouping Explanation

Substitution of the AB7050 is based on the following critical parameters that must remain consistent:

• Dimensional specifications: Length 11.693" (297.00mm), Width 8.268" (210.00mm), Thickness 0.022" (0.55mm)
• Material composition: Polymer resin with metal flakes
• Adhesive configuration: Non-conductive, single-sided application
• Operating temperature range: -25°C to 85°C
• Functional classification: RF EMI absorbing sheet

The AB7050HF qualifies as a direct substitute based on identical dimensional and material specifications, with the distinction of active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The AB7050HF is the direct substitute for the obsolete AB7050. Both parts maintain identical dimensional, material, and thermal specifications, ensuring functional equivalence in RF EMI absorption applications.

The AB7050HF offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the AB7050HF carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The moisture sensitivity level classification of 1 (Unlimited) for the AB7050HF indicates no special moisture handling requirements during storage or transport, simplifying logistics and inventory management compared to moisture-sensitive alternatives.

Frequently Asked Questions (FAQ)

Q: Can AB7050HF be used as a direct replacement for AB7050?
