3M 1267 X 6" RF EMI Shielding Sheet - Equivalent & Substitute Parts

Part Overview

The 3M 1267 X 6" is an RF EMI shielding sheet constructed from embossed aluminum foil with non-conductive, single-sided adhesive. This product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing procurement and design continuity. The sheet format (12.000" × 6.000" × 0.005") serves applications requiring large-area electromagnetic interference shielding with adhesive backing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1267 X 6" are identified within the 3M 1267 series based on the following criteria:

Material Compatibility: All substitutes maintain embossed aluminum foil construction with non-conductive, single-sided adhesive, ensuring equivalent electromagnetic shielding performance.

Thickness Consistency: All alternatives maintain 0.005" (0.13mm) thickness, preserving electrical and mechanical properties.

Series Alignment: All substitute parts belong to the 3M 1267 product series, confirming design and performance equivalence.

Regulatory Compliance: All parts share identical ECCN (EAR99) and HTSUS classifications, ensuring procurement and export compliance consistency.

The substitutes differ in format (tape vs. sheet) and dimensional configuration (length and width), allowing selection based on application-specific coverage requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Sheet Format Replacement: The 1267 X 6" is obsolete with no active sheet-format substitute within the provided data. Applications requiring pre-cut sheet geometry must evaluate the tape-format alternatives for coverage area equivalence.

For Tape Format Alternatives: Both 1267 X 1" and 6-6-1267 are active products with current manufacturing status. The 1267 X 1" provides 54 feet of 1-inch width material, while 6-6-1267 provides 18 feet of 6-inch width material. Selection depends on application geometry and installation method.

Compliance Continuity: All alternatives maintain EAR99 export classification and 7607.20.5000 HTSUS coding, ensuring regulatory consistency in procurement workflows.

RoHS and REACH Status: The 1267 X 1" is RoHS Compliant; 6-6-1267 is ROHS3 Compliant. Both are REACH Unaffected or equivalent, supporting environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can 1267 X 1" tape replace the 1267 X 6" sheet directly?

A: The 1267 X 1" provides equivalent material composition, thickness, and adhesive properties. However, it is supplied as 54-foot tape in 1-inch width rather than a pre-cut 12" × 6" sheet. Coverage area equivalence must be calculated: 54 feet × 1 inch = 54 square feet versus the sheet's 0.5 square feet. Multiple applications or cutting may be required.

Q: What is the difference between 1267 X 1" and 6-6-1267?

A: Both are tape formats with identical material and thickness. The 1267 X 1" is 54 feet long at 1-inch width; 6-6-1267 is 18 feet long at 6-inch width. The 6-6-1267 matches the original sheet width (6 inches), reducing the number of parallel strips needed for equivalent coverage.

Q: Are all substitutes electrically equivalent?

A: Yes. All parts use embossed aluminum foil with non-conductive, single-sided adhesive at 0.005" thickness, ensuring equivalent RF EMI shielding performance and electrical properties.

Q: What packaging formats are available?

A: The 1267 X 6" sheet is supplied in standard packaging; 1267 X 1" is supplied in Box packaging; 6-6-1267 is supplied in Bulk packaging. Packaging selection may affect order quantities and handling procedures.

Q: Are there storage or shelf-life considerations?

A: Moisture Sensitivity Level is Not Applicable for the main part and 1267 X 1". The 6-6-1267 has MSL 1 (Unlimited), indicating no moisture-related storage restrictions. All parts support standard warehouse storage conditions.
