3M 1267 X 1" RF EMI Shielding Sheet - Equivalent & Substitute Parts

Part Overview

The 3M 1267 X 1" is an RF EMI shielding sheet constructed from embossed aluminum foil with non-conductive, single-sided adhesive. This product is discontinued at DiGi Electronics but remains available in inventory. RF EMI shielding sheets are essential components in electronic enclosures and assemblies where electromagnetic interference mitigation is required. Due to the discontinued status of this specific sheet format, equivalent substitute products in tape configuration are available to meet functional requirements.

Key Parameters

Substitute Part Grouping Explanation

The 3M 1267 series maintains consistent electrical and mechanical specifications across product formats. Substitution is based on the following critical parameters that remain constant:

• Material composition: Embossed aluminum foil
• Width: 1.000" (25.40mm)
• Thickness: 0.005" (0.13mm)
• Adhesive system: Non-conductive, single-sided
• Series designation: 1267
• Regulatory compliance: RoHS status

The primary difference between the main part and substitute is the format: the original is supplied as a sheet (36" length), while the substitute is supplied as a tape (18' length). Both formats deliver identical shielding performance and material properties. The tape format provides extended length in a more practical dispensing configuration.

Parameter Comparison

Engineering Selection Recommendations

The 3M 1-6-1267 shielding tape is the designated manufacturer substitute for the discontinued 3M 1267 X 1" sheet. Selection is based on:

• Identical material composition and electrical properties
• Matching width and thickness specifications
• Equivalent adhesive system performance
• Active product status with established supply chain
• Enhanced regulatory compliance (ROHS3 vs. RoHS Compliant)
• Defined shelf life and storage requirements
• Extended length (18 feet vs. 36 inches) providing greater material availability per unit

The tape format is suitable for applications requiring continuous or segmented shielding coverage where the extended length provides operational advantages over discrete sheet segments.

Frequently Asked Questions (FAQ)

Q: Can the 3M 1-6-1267 tape directly replace the 3M 1267 X 1" sheet?

A: Yes. Both products share identical material composition, width, thickness, and adhesive properties. The primary difference is format: tape versus sheet. The tape provides 18 feet of continuous material compared to the sheet's 36-inch length.

Q: Are there electrical performance differences between the sheet and tape formats?

A: No. Both formats use embossed aluminum foil with identical thickness (0.005") and non-conductive single-sided adhesive. Electromagnetic shielding performance is equivalent.

Q: What is the advantage of the tape format over the sheet?

A: The tape format provides extended length (18 feet) in a roll configuration, enabling continuous application and reducing the number of segments required for longer shielding runs. This format is more practical for production environments requiring consistent material dispensing.

Q: Are storage conditions different between the two products?

A: Yes. The tape specifies storage at 50°F ~ 80°F (10°C ~ 27°C) with a 60-month shelf life from date of manufacture. The sheet format does not specify storage requirements. Compliance with tape storage specifications is recommended for optimal adhesive performance.

Q: Does the tape format require different application procedures?

A: No. Both products use non-conductive single-sided adhesive and are applied using identical techniques. The tape's roll format simply allows for continuous or segmented application as required by the application.

Q: Are both products RoHS compliant?

A: Yes. The sheet is RoHS Compliant. The tape is ROHS3 Compliant, representing a more current regulatory standard. Both meet RoHS requirements.
