Equivalent & Substitute Parts for Laird Technologies EMI 3535-S

Part Overview

The Laird Technologies EMI 3535-S is an RF EMI absorbing sheet manufactured in the Q-Zorb series. This rectangular absorbing sheet measures 6.000" (152.40mm) in length, 4.000" (101.60mm) in width, and 0.020" (0.51mm) in thickness, with pressure sensitive adhesive (PSA) backing. The product is classified as obsolete, necessitating identification of equivalent substitute components for ongoing applications requiring RF EMI absorption functionality with PSA attachment.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 3535-S are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Product type: RF EMI absorbing sheet
• Adhesive system: Pressure sensitive adhesive (PSA)
• Manufacturer: Laird Technologies EMI
• Functional application: RF EMI absorption

Secondary Compatibility Factors:

• Overall thickness range
• Dimensional coverage area
• Regulatory compliance (ECCN, RoHS status)
• Product status (active vs. obsolete)

The substitute part NS1010S from the NoiseSorb NS1000 series meets the core functional requirements as an RF EMI absorbing sheet with PSA backing from the same manufacturer. While dimensional specifications differ, both products serve equivalent RF EMI absorption applications with adhesive attachment methods.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 3535-S is classified as obsolete. The NS1010S substitute is an active product from Laird Technologies EMI, ensuring ongoing availability and manufacturing support.

Regulatory Compliance: Both parts carry EAR99 classification. The NS1010S provides additional RoHS compliance certification, meeting current environmental regulatory requirements.

Functional Equivalence: Both products function as RF EMI absorbing sheets with PSA attachment. The NS1010S operates across a defined temperature range (-40°C ~ 105°C), whereas the 3535-S does not specify operating temperature limits.

Dimensional Differences: The 3535-S provides a rectangular coverage area of 24 square inches (6.000" × 4.000"). The NS1010S provides a square coverage area of approximately 15.5 square inches (3.940" × 3.940"). The 3535-S is significantly thicker (0.020" vs. 0.004"), which may affect absorption characteristics and mechanical properties.

Selection between these parts depends on specific dimensional and thickness requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the NS1010S directly replace the 3535-S in all applications?

A: Both products are RF EMI absorbing sheets with PSA backing from Laird Technologies EMI. However, dimensional and thickness differences exist. The 3535-S is larger (6.000" × 4.000" × 0.020") compared to the NS1010S (3.940" × 3.940" × 0.004"). Application-specific requirements for coverage area and thickness must be evaluated.

Q: What are the key differences between these two products?

A: The primary differences are shape (rectangular vs. square), overall dimensions, thickness, and product status. The 3535-S is obsolete; the NS1010S is active. The NS1010S includes RoHS compliance and specified operating temperature range (-40°C ~ 105°C).

Q: Why is the 3535-S obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The NS1010S from the active NoiseSorb NS1000 series represents the current equivalent offering from Laird Technologies EMI.

Q: Are both products suitable for RF EMI absorption applications?

A: Yes. Both products are classified as RF EMI absorbing sheets with PSA adhesive systems, designed for electromagnetic interference absorption in electronic applications.

Q: What is the significance of the thickness difference?

A: The 3535-S thickness of 0.020" (0.51mm) differs substantially from the NS1010S thickness of 0.004" (0.10mm). Thickness affects absorption performance, mechanical properties, and space constraints in applications. Application requirements determine which thickness is appropriate.

Q: Are there packaging or inventory considerations?

A: The 3535-S has 799 pieces in stock (new original). The NS1010S has 877 pieces in stock (new original). Both are available as new original inventory.
