Regulatory Compliance: All substitute parts maintain RoHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and safety standards.

Manufacturer Continuity: Laird Technologies EMI remains the manufacturer across all substitute options, guaranteeing consistent material quality and performance specifications.

The substitute part 4106-S is identified as an active product within the Laird Technologies EMI portfolio, providing continuity for applications previously utilizing the obsolete 4106 absorbing sheet.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 4106 is classified as obsolete. The 4106-S substitute maintains active product status within the Laird Technologies EMI catalog, ensuring long-term availability and continued manufacturer support.

Compliance Alignment: Both parts satisfy current regulatory requirements. The 4106-S demonstrates ROHS3 compliance, representing the current generation of environmental standards compliance, while the original 4106 maintains RoHS compliance. Both parts are REACH unaffected and classified under ECCN EAR99.

Material and Dimensional Consistency: The polyurethane foam construction and 0.500" (12.70mm) thickness specification are maintained in the substitute part, preserving electromagnetic absorption performance characteristics required for RF EMI suppression applications.

Inventory Availability: Both parts maintain adequate stock levels. The 4106-S provides 816 pieces of new original inventory, supporting immediate procurement requirements for applications transitioning from the obsolete 4106.

Frequently Asked Questions (FAQ)

Q: Can the 4106-S directly replace the 4106 in existing applications?

A: The 4106-S maintains identical material composition (polyurethane foam) and thickness specification (0.500" / 12.70mm), which are the primary parameters determining RF EMI absorption performance. However, the 4106-S is classified as a gasket type component, while the 4106 is an absorbing sheet. Application-specific dimensional requirements must be evaluated, as the 4106-S dimensions (6.000" × 4.000") differ from the 4106 (24.000" × 24.000").

Q: What is the significance of the thickness parameter in substitution?

A: Thickness directly determines electromagnetic wave attenuation characteristics. Both the 4106 and 4106-S maintain 0.500" (12.70mm) thickness, ensuring equivalent RF absorption performance at specified frequency ranges.

Q: Are there compliance differences between the two parts?

A: Both parts satisfy current regulatory frameworks. The 4106-S demonstrates ROHS3 compliance, representing the current generation standard. Both parts maintain REACH unaffected status and EAR99 export classification.

Q: What is the shelf life consideration for the 4106-S?

A: The 4106-S specifies a 60-month shelf life from the date of manufacture. The original 4106 does not provide shelf life specification. This parameter is relevant for long-term inventory management and procurement planning.

Q: How do the dimensional differences affect substitution feasibility?

A: The 4106 provides a 24.000" × 24.000" square format suitable for broad-area coverage applications. The 4106-S provides a 6.000" × 4.000" rectangular format optimized for gasket applications. Dimensional compatibility must be evaluated based on specific application requirements and available mounting space.
