3M 3/4-6-1183 RF EMI Shielding Tape Equivalent & Substitute Parts

Part Overview

The 3M 3/4-6-1183 is an RF EMI shielding tape constructed from tin-plated copper foil with conductive, single-sided adhesive. This product is designed for electromagnetic interference shielding applications requiring reliable conductive bonding in compact form factors. The part is currently active in production status. Alternative part numbers may be required when specific packaging configurations, roll lengths, or bulk ordering requirements differ from standard inventory allocations.

Key Parameters

Substitute Part Grouping Explanation

The 3M 1183 series shielding tape is available in multiple roll length configurations while maintaining identical electrical and mechanical specifications. Substitution between part numbers within this series is determined by the following critical parameters:

• Material composition: Tin-plated copper foil (identical across all variants)
• Adhesive system: Conductive, single-sided (identical across all variants)
• Width: 0.750" (19.10mm) (identical across all variants)
• Thickness: 0.003" (0.07mm) (identical across all variants)
• Operating temperature range: -40°C to 130°C (identical across all variants)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected (identical across all variants)

The primary differentiator between equivalent parts is roll length and packaging configuration. The 3/4-6-1183 is supplied in box packaging with an 18-foot roll length, while the 1183-3/4X18YD variant is supplied in bulk packaging with a 54-foot roll length. Both parts are functionally equivalent for EMI shielding applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3/4-6-1183 and 1183-3/4X18YD are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on application requirements for roll length and packaging format:

• 3/4-6-1183 (18-foot roll, box packaging): Suitable for applications requiring smaller quantities or standard box distribution.
• 1183-3/4X18YD (54-foot roll, bulk packaging): Suitable for high-volume applications or bulk procurement scenarios requiring extended roll length.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component applications. Storage conditions of 50°F to 80°F (10°C to 27°C) with 60-month shelf life apply to both variants.

Frequently Asked Questions (FAQ)

Q: Can 1183-3/4X18YD be used as a direct substitute for 3/4-6-1183?

A: Yes. Both parts are functionally equivalent for EMI shielding applications. The primary difference is roll length (54 feet versus 18 feet) and packaging format (bulk versus box). Electrical and mechanical performance characteristics are identical.

Q: What determines compatibility between these shielding tape variants?

A: Compatibility is determined by material composition (tin-plated copper foil), adhesive type (conductive, single-sided), width (0.750"), thickness (0.003"), and operating temperature range (-40°C to 130°C). All these parameters are identical across both part numbers.

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

A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 1 - Unlimited) and shelf life (60 months) are also identical.

Q: When should bulk packaging (1183-3/4X18YD) be selected over box packaging (3/4-6-1183)?

A: Bulk packaging is appropriate for applications requiring extended roll lengths or high-volume production runs where the 54-foot roll length provides cost efficiency and reduced changeover frequency compared to multiple 18-foot rolls.

Q: What storage conditions apply to both part variants?

A: Both parts require storage at 50°F to 80°F (10°C to 27°C) with a shelf life of 60 months from the date of manufacture.
