Equivalent & Substitute Parts for Laird Technologies EMI 3536

Part Overview

The Laird Technologies EMI 3536 is an RF EMI absorbing sheet manufactured from CA19 polymer with magnetic powder composition. This rectangular absorbing sheet measures 13.000" × 12.000" × 0.020" and features non-conductive, single-sided adhesive for electromagnetic interference mitigation applications.

The 3536 has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure continued availability for applications requiring RF EMI absorption with comparable electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the 3536 is based on the following critical parameters that define functional equivalence in RF EMI absorbing sheet applications:

Primary Substitution Criteria:

• Product type classification (Absorbing Sheet)
• Rectangular shape geometry
• Material composition (polymer-based with magnetic or foam properties)
• Adhesive system (non-conductive or pressure-sensitive adhesive)
• Overall thickness range suitable for EMI absorption
• Regulatory compliance (ECCN classification)

The substitute part NS1040 qualifies as an equivalent alternative based on matching product type, rectangular geometry, polymer-based material system, and adhesive application method. Both parts are classified under ECCN EAR99 and serve identical functional purposes in RF EMI absorption applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 3536 is classified as obsolete, making NS1040 the active substitute from Laird Technologies EMI. NS1040 maintains current manufacturing status and supply chain availability.

Regulatory Compliance: Both parts carry identical ECCN EAR99 classification, confirming equivalent export control treatment. NS1040 provides additional RoHS3 compliance certification, meeting current environmental regulatory requirements.

Material and Adhesive Differences: The 3536 uses CA19 polymer with magnetic powder and non-conductive adhesive. NS1040 employs polyurethane foam with pressure-sensitive adhesive (PSA). Both material systems function as RF EMI absorbing media with non-conductive adhesive properties suitable for electromagnetic shielding applications.

Dimensional Variance: NS1040 dimensions are smaller than the 3536 (11.811" × 8.268" versus 13.000" × 12.000"). Thickness differs by 0.004" (0.11mm). Application-specific coverage area requirements must be evaluated against these dimensional differences.

Operating Temperature: NS1040 specifies operating temperature range of -40°C to 105°C. The 3536 does not provide temperature specifications. Applications requiring defined thermal performance should reference NS1040 specifications.

Frequently Asked Questions (FAQ)

Q: Can NS1040 directly replace the 3536 in existing designs?

A: NS1040 functions as an RF EMI absorbing sheet equivalent to the 3536. However, dimensional differences (NS1040 is smaller) and material composition differences (polyurethane foam versus CA19 polymer) require design review. Coverage area and specific EMI absorption characteristics must be evaluated for your application.

Q: What are the key differences between the 3536 and NS1040?

A: Primary differences include: material composition (CA19 polymer with magnetic powder versus polyurethane foam), adhesive type (non-conductive single-sided versus pressure-sensitive adhesive), dimensions (3536 is larger), thickness (3536 is thicker by 0.004"), and product status (3536 is obsolete; NS1040 is active). Both are rectangular absorbing sheets with non-conductive adhesive systems and identical ECCN classification.

Q: Is NS1040 RoHS compliant?

A: Yes, NS1040 is ROHS3 compliant. The 3536 RoHS status is not specified in available documentation.

Q: What is the shelf life of NS1040?

A: NS1040 has a 24-month shelf life from the date of shipment. The 3536 shelf life is not specified.

Q: Are both parts suitable for the same frequency ranges?

A: Both parts are classified as RF EMI absorbing sheets and serve identical functional purposes. Specific frequency absorption characteristics are not provided in the available parameters. Application-specific frequency performance should be confirmed through technical datasheets or application notes from Laird Technologies EMI.

Q: What packaging is available for NS1040?

A: NS1040 is supplied in box packaging. The 3536 packaging format is not specified.
