3M 1194 RF EMI Shielding Tape Equivalent & Substitute Parts

Part Overview

The 3M 1194 is a copper foil-based RF EMI shielding tape designed for electromagnetic interference mitigation applications. This product features a non-conductive, single-sided adhesive configuration with dimensions of 6.000" (152.40mm) width and 108.005' (32.92m) length. The part is currently discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives that maintain the same electrical and mechanical specifications for continued procurement and application compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3M 1194 RF EMI shielding tape is determined by the following critical parameters that must remain constant:

Material composition (copper foil), width (6.000" / 152.40mm), thickness (0.003" / 0.07mm), adhesive configuration (non-conductive, single-sided), and series designation (1194). The substitute part 6-6-1194 maintains all these core electrical and mechanical parameters. The primary difference between the main part and the substitute is the length specification: the original 1194 provides 108.005' (32.92m) of tape, while the 6-6-1194 substitute provides 11.970" (304.00mm) in a bulk packaging format. Both parts are manufactured by 3M and comply with identical regulatory standards (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Parameter Comparison

Engineering Selection Recommendations

The 3M 6-6-1194 is an active substitute for the discontinued 3M 1194 RF EMI shielding tape. Both parts maintain identical electrical and mechanical specifications: copper foil material, 6.000" width, 0.003" thickness, and non-conductive single-sided adhesive configuration. Both parts satisfy ROHS3 compliance and REACH regulatory requirements. The primary consideration for selection is length requirement: the original 1194 provides 108.005' (32.92m) of continuous tape, while the 6-6-1194 substitute provides 11.970" (304.00mm) in bulk packaging. Component selection should be based on the total length of shielding tape required for the application. The substitute part's active product status ensures continued availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the 3M 6-6-1194 directly replace the 3M 1194 in existing applications?

A: Yes, the 6-6-1194 is a direct electrical and mechanical substitute. Both parts share identical material composition (copper foil), width (6.000"), thickness (0.003"), and adhesive configuration (non-conductive, single-sided). The primary difference is the length per unit: 108.005' versus 11.970". Selection depends on the total length requirement for your application.

Q: What is the significance of the length difference between these parts?

A: The 3M 1194 provides 108.005' (32.92m) of tape in standard packaging, while the 6-6-1194 provides 11.970" (304.00mm) in bulk packaging. The length specification determines the total coverage area available per unit. Applications requiring extended continuous shielding may need multiple units of the shorter 6-6-1194 substitute.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 3M 1194 and 3M 6-6-1194 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain MSL rating 1 (unlimited moisture sensitivity level).

Q: Why is the original 3M 1194 discontinued?

A: The 3M 1194 is discontinued at DiGi Electronics. The active substitute 3M 6-6-1194 maintains all critical electrical and mechanical parameters and is currently available for procurement.

Q: Does packaging format affect the electrical performance of the shielding tape?

A: No. Packaging format (standard versus bulk) does not affect the electrical or mechanical performance of the copper foil shielding tape. Both parts deliver identical EMI shielding characteristics based on their material composition, dimensions, and adhesive properties.
