AL-50BT RF EMI Shielding Sheet Equivalent & Substitute Parts

Part Overview

The AL-50BT is a single-sided conductive aluminum foil RF EMI shielding sheet manufactured by 3M, with dimensions of 10.000" (254.00mm) length × 6.560" (166.00mm) width and 0.003" (0.08mm) thickness. This product is classified as obsolete, making identification of suitable substitute components necessary for ongoing applications requiring RF electromagnetic interference shielding functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AL-50BT is determined by the following critical parameters:

Material composition (aluminum foil), adhesive configuration (conductive, single-sided), thickness (0.003" / 0.08mm), and functional type (RF EMI shielding sheet). The substitute part 3M 1170 7.7"×10" maintains identical material, adhesive type, and thickness specifications. The primary dimensional difference is width: the substitute provides 7.700" (195.00mm) width compared to the original 6.560" (166.00mm), while length remains constant at 10.000" (254.00mm). This dimensional variance represents an increase in coverage area while preserving the core shielding functionality and physical properties required for RF EMI applications.

Parameter Comparison

Engineering Selection Recommendations

The 3M 1170 7.7"×10" serves as the direct substitute for the obsolete AL-50BT. Both components share identical material composition, adhesive configuration, and thickness specifications essential for RF EMI shielding applications. The substitute maintains active product status with confirmed RoHS compliance and REACH unaffected designation, supporting regulatory requirements for current manufacturing environments. The increased width dimension of the substitute (7.700" versus 6.560") provides expanded coverage capability while maintaining compatibility with the standard 10.000" length. Selection of the 1170 7.7"×10" is appropriate for applications previously utilizing the AL-50BT where the additional width does not present mechanical constraints.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting the AL-50BT?

A: Material (aluminum foil), adhesive type (conductive, single-sided), thickness (0.003" / 0.08mm), and shielding sheet functionality must remain constant. The 1170 7.7"×10" maintains all these specifications.

Q: How does the width difference affect substitution suitability?

A: The substitute provides 7.700" width compared to the original 6.560" width. This represents a 1.140" increase in width dimension. Applications must accommodate this larger width, or material can be trimmed to original dimensions if space constraints exist.

Q: Is the 1170 7.7"×10" RoHS compliant?

A: Yes, the 1170 7.7"×10" is RoHS compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing.

Q: What is the shelf life of the substitute part?

A: The 1170 7.7"×10" has a 60-month shelf life from the date of manufacture, with recommended storage temperature range of 50°F to 80°F (10°C to 27°C).

Q: Are both parts classified under the same export control category?

A: Yes, both the AL-50BT and 1170 7.7"×10" are classified under ECCN EAR99 and HTSUS 7607.19.6000.
