RF EMI Absorb Sheet 21199219 Equivalent & Substitute Parts

Part Overview

The Laird Technologies EMI part number 21199219 is an RF EMI absorbing sheet with dimensions of 0.060" thickness by 12" width by 36" length. This component is classified as obsolete and is no longer in active production. RF EMI absorbing sheets are used in electronic applications to attenuate electromagnetic interference across radio frequency spectra. Due to the obsolete status of part 21199219, identification of functionally equivalent active alternatives is necessary for ongoing design support and procurement continuity.

Functional Category: Both components are RF EMI absorbing sheets manufactured by Laird Technologies EMI, serving the same electromagnetic interference attenuation function.

Material Classification: The substitute part 21109160 is specified as an ECCOSORB® MCS series silicone rubber-based absorbing sheet, representing the active product line continuation for this application category.

Adhesive System: The substitute incorporates a Pressure Sensitive Adhesive (PSA) system, enabling direct surface mounting without additional fastening requirements.

Compliance Status: The substitute part 21109160 carries active product status with RoHS3 compliance certification and EAR99 export classification, supporting current regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Part number 21109160 is the designated equivalent for obsolete part 21199219. This substitution is supported by:

1. Active Product Status: Part 21109160 maintains active production status with current inventory availability (741 pcs), ensuring long-term procurement viability compared to the obsolete original part.

2. Regulatory Compliance: The substitute carries RoHS3 compliance certification, meeting current environmental and hazardous substance restrictions applicable to electronic components in regulated markets.

3. Export Classification: EAR99 classification of the substitute part aligns with standard commercial export requirements for RF absorbing materials.

4. Dimensional Alignment: Matching planar dimensions (12" × 36") ensure direct mechanical compatibility with existing designs and mounting structures.

5. Material Specification: The silicone rubber composition with PSA adhesive provides documented material properties and thermal performance (170°C operating temperature), establishing clear performance parameters for design validation.

Design Consideration: The thickness differential between the original part (0.060") and substitute (0.039") requires evaluation within the specific application context. Applications with strict thickness constraints should confirm compatibility with the reduced profile of part 21109160.

Frequently Asked Questions (FAQ)

Q: Can part 21109160 be used as a direct replacement for 21199219 in all applications?

A: Part 21109160 is mechanically and functionally compatible based on matching planar dimensions and RF EMI absorbing sheet classification. However, the thickness reduction from 0.060" to 0.039" requires confirmation that the application does not impose strict thickness requirements. Verify that the reduced profile does not compromise electromagnetic performance or mechanical fit in the specific installation.

Q: What is the significance of the PSA (Pressure Sensitive Adhesive) on part 21109160?

A: The PSA system on part 21109160 enables direct adhesive mounting to surfaces without mechanical fasteners or additional adhesive application. This differs from the original part 21199219, for which adhesive specifications were not provided. Confirm that PSA mounting is compatible with the intended substrate and application environment.

Q: Does the RoHS3 compliance of part 21109160 affect compatibility with existing designs?

A: RoHS3 compliance indicates that part 21109160 meets current environmental standards for hazardous substance restrictions. This certification supports regulatory compliance for new designs and procurement in regulated markets. Existing designs using the obsolete part 21199219 do not require modification to accommodate RoHS3 compliance of the substitute.

Q: What is the operating temperature range for part 21109160?

A: Part 21109160 is specified for operation up to 170°C. This thermal rating should be verified against the maximum operating temperature requirements of the application. The original part 21199219 did not provide operating temperature specifications.

Q: Are there packaging differences between the main part and substitute?

A: Part 21199219 packaging was not specified in available documentation. Part 21109160 is supplied in bulk packaging. Confirm that bulk packaging meets procurement and handling requirements for the intended application.

Q: What is the shelf life of part 21109160?

A: Part 21109160 carries a 24-month shelf life from the date of shipment. Proper storage conditions should be maintained to preserve material properties throughout the shelf life period.

Q: How does the ECCN classification difference affect procurement?

A: The original part 21199219 carried an OBSOLETE ECCN classification. The substitute part 21109160 is classified as EAR99, which is the standard commercial classification for RF absorbing materials. EAR99 classification supports standard commercial export and procurement channels without additional licensing requirements for most destinations.
