5-AB5050-1.5 RF EMI Absorbing Sheet Equivalent & Substitute Parts

Part Overview

The 5-AB5050-1.5 is an RF EMI absorbing sheet from 3M's AB-5000 series, featuring a circular design with 1.500" (38.10mm) diameter and 0.022" (0.55mm) thickness. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The sheet utilizes polymer resin with metal flakes in a non-conductive, single-sided adhesive configuration for electromagnetic interference suppression applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5-AB5050-1.5 is determined by the following critical parameters:

Material Composition: Both the main part and substitute must utilize polymer resin with metal flakes to maintain electromagnetic absorption characteristics.

Adhesive Configuration: Non-conductive, single-sided adhesive is required for electrical isolation and application compatibility.

Operating Temperature Range: The substitute must support the thermal envelope of -25°C to 85°C or equivalent.

Regulatory Compliance: Both parts must maintain EAR99 classification and HTSUS code 3919.90.5060 for trade and export consistency.

Moisture Sensitivity: MSL 1 (Unlimited) classification ensures no special handling requirements during storage and deployment.

The substitute part AB5050SHF-210X297 shares the core material composition, adhesive type, regulatory classification, and moisture sensitivity level. However, it differs in form factor (rectangular versus circular) and dimensional specifications, requiring evaluation based on specific application geometry constraints.

Parameter Comparison

Engineering Selection Recommendations

The AB5050SHF-210X297 is an active product from 3M's RF EMI absorbing sheet portfolio and serves as the primary substitute for the obsolete 5-AB5050-1.5. Both components share identical material composition (polymer resin with metal flakes), adhesive configuration (non-conductive, single-sided), regulatory classification (EAR99), and moisture sensitivity rating (MSL 1).

The substitute part carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment for modern applications. The thickness differential (0.020" versus 0.022") and dimensional change from circular to rectangular form factor require application-specific validation to ensure mechanical and electrical performance equivalence.

Selection of the AB5050SHF-210X297 is appropriate for applications where the larger rectangular format (8.268" × 11.693") can accommodate the original circular 1.500" diameter requirement through cutting or positioning within the available sheet area.

Frequently Asked Questions (FAQ)

Q: Can the AB5050SHF-210X297 directly replace the 5-AB5050-1.5 in existing assemblies?

A: Direct replacement depends on application geometry. The substitute is a larger rectangular sheet that can be cut or positioned to provide the required circular coverage area. The material composition and adhesive properties are equivalent.

Q: What is the significance of the thickness difference between 0.022" and 0.020"?

A: Both thicknesses fall within the standard range for RF EMI absorbing sheets in this product category. The 0.002" (0.05mm) difference is within typical manufacturing tolerance and does not alter the functional classification of the material.

Q: Are there any compliance differences between the two parts?

A: The substitute part (AB5050SHF-210X297) includes ROHS3 compliance and REACH unaffected certification, whereas the main part specifications do not document these certifications. Both maintain EAR99 classification and identical HTSUS coding.

Q: What packaging format is available for the substitute part?

A: The AB5050SHF-210X297 is supplied in box packaging, compared to the original 5-pack configuration of the 5-AB5050-1.5.

Q: Are storage and handling requirements identical between the two parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no special moisture sensitivity precautions are required. The substitute specifies storage at 70°F (21°C) with a 12-month shelf life from date of shipment.
