3M 1267 RF EMI Shielding Tape 54'X1" - Equivalent & Substitute Parts

Part Overview

The 3M 1267 is an RF EMI shielding tape constructed from embossed aluminum foil with non-conductive, single-sided adhesive. The main part is supplied in a 1.000" (25.40mm) width × 54.000' (16.50m) length configuration with 0.005" (0.13mm) thickness. This product is Active status and RoHS Compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across different packaging or length configurations within the same product series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the 3M 1267 series is determined by maintaining identical electrical and mechanical properties: material composition (embossed aluminum foil), adhesive type (non-conductive, single-sided), width (1.000"), and thickness (0.005"). The primary variable between the main part and substitute is the tape length, which affects packaging format and total coverage area but does not alter the fundamental shielding or adhesive characteristics. Both parts maintain Active product status and RoHS compliance, confirming functional equivalence for RF EMI shielding applications.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and full regulatory compliance (RoHS, REACH, EAR99). The 3M 1267 X 1" (54' length) is suitable for applications requiring extended coverage in a single roll. The 3M 1-6-1267 (18' length) provides the same shielding performance and adhesive properties in a shorter configuration with bulk packaging. Selection between these parts depends on application coverage requirements and inventory management preferences. Both parts are electrically and mechanically equivalent for RF EMI shielding applications.

Frequently Asked Questions (FAQ)

Q: Can 3M 1-6-1267 replace 3M 1267 X 1" in RF EMI shielding applications?

A: Yes. Both parts use identical embossed aluminum foil material, non-conductive single-sided adhesive, width (1.000"), and thickness (0.005"). The difference is tape length: 54' versus 18'. Substitution is valid when application coverage requirements can be met with the shorter length.

Q: What is the difference between Box and Bulk packaging?

A: The main part (1267 X 1") is supplied in Box packaging, while the substitute (1-6-1267) is supplied in Bulk packaging. Packaging format does not affect the electrical or mechanical properties of the shielding tape.

Q: Are both parts RoHS compliant?

A: Yes. The main part is RoHS Compliant, and the substitute is ROHS3 Compliant. Both meet RoHS requirements and are suitable for regulated applications.

Q: What does MSL 1 (Unlimited) mean for the substitute part?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component has unlimited shelf life under standard storage conditions without requiring special moisture control measures.

Q: Are there any regulatory or export restrictions?

A: Both parts are classified as EAR99 and REACH Unaffected, indicating no special export licensing requirements and no REACH substance of concern restrictions.
