RF EMI Absorber Sheet 21199160 Equivalent & Substitute Parts

Part Overview

The Laird Technologies EMI part number 21199160 is an RF EMI absorber sheet with dimensions of 0.030" thickness, 12" width, and 36" length. This component is classified as obsolete and is no longer in active production. RF EMI absorber sheets are used in electromagnetic interference mitigation applications where signal absorption and shielding are required. Due to the obsolete status of this part, identifying active equivalent substitutes is necessary for continued system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 21109160 is identified as a functional equivalent based on the following substitution criteria:

Primary Substitution Parameters:

• Product category: RF EMI absorber sheet
• Manufacturer: Laird Technologies EMI (same manufacturer)
• Dimensional compatibility: Both parts feature 12" width and 36" length dimensions
• Thickness specification: Original part 0.030" (0.76mm) compared to substitute 0.039" (1.00mm) represents a minor thickness variation within acceptable tolerance for EMI absorption applications
• Material composition: Silicone rubber base material
• Adhesive type: Pressure sensitive adhesive (PSA) for both applications

The substitute part 21109160 maintains the same functional purpose and core dimensional parameters while offering active product status and full technical documentation.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

Part 21109160 is a direct functional substitute for the obsolete part 21199160. Both components are manufactured by Laird Technologies EMI and share identical length and width dimensions (36" × 12"). The thickness differential of 0.009" (0.24mm) represents a 30% increase in material thickness, which provides enhanced EMI absorption characteristics while maintaining the same footprint.

Compliance Status:

The substitute part 21109160 carries active product status with ROHS3 compliance certification and EAR99 export classification. The original part 21199160 is classified as obsolete with no current compliance documentation available. For new designs or system replacements, part 21109160 is the appropriate selection.

Technical Considerations:

The substitute part includes documented operating temperature rating of 170°C and specified material composition (silicone rubber with PSA adhesive). These parameters are not provided for the original part. The increased thickness of the substitute part (0.039" versus 0.030") may require verification of mechanical fit in space-constrained applications, though dimensional compatibility remains within the same product family.

Frequently Asked Questions (FAQ)

Q: Can part 21109160 directly replace part 21199160 in existing applications?

A: Part 21109160 is dimensionally compatible in length and width (both 36" × 12"). The thickness increase from 0.030" to 0.039" must be evaluated for mechanical fit in the specific application. The substitute part maintains the same material type and adhesive system.

Q: What is the significance of the thickness difference between these parts?

A: The original part 21199160 specifies 0.030" thickness, while substitute 21109160 is 0.039" thick. This 0.009" difference represents enhanced material volume for EMI absorption. Applications with strict thickness constraints require physical verification before substitution.

Q: Is part 21109160 compliant with current regulatory requirements?

A: Yes. Part 21109160 is ROHS3 compliant and carries EAR99 export classification. The original part 21199160 is obsolete and lacks current compliance documentation.

Q: What packaging options are available for part 21109160?

A: Part 21109160 is supplied in bulk packaging format. Specific packaging quantities and configurations should be verified with the supplier based on application requirements.

Q: Are both parts manufactured by the same company?

A: Yes. Both part 21199160 and substitute 21109160 are manufactured by Laird Technologies EMI, ensuring consistent material quality and performance characteristics within the ECCOSORB® product family.

Q: What is the shelf life of the substitute part?

A: Part 21109160 has a documented shelf life of 24 months from the date of shipment. Storage conditions should maintain standard environmental parameters.
