RF EMI Gasket 4106-.25 Equivalent & Substitute Parts

Part Overview

The Laird Technologies EMI 4106-.25 is an RF EMI gasket designed for electromagnetic interference shielding applications. This sheet-form gasket measures 12.000" × 12.000" × 0.500" and is currently in active production status. The gasket provides EMI containment in electronic enclosures and shielded compartments. Substitute parts may be required due to inventory constraints, application-specific dimensional requirements, or procurement lead time considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF EMI gaskets is determined by the following parameters:

Critical Parameters for Substitution:

• Thickness (Overall): 0.500" (12.70mm) — must remain constant for proper sealing and shielding effectiveness
• Product Type: Gasket — functional category must be maintained
• Shape: Sheet — form factor requirement
• RoHS and REACH Compliance: Both parts must meet regulatory requirements

Variable Parameters:

• Length and Width dimensions may differ based on application requirements
• Series designation may vary (e.g., RFRET 4000 series)
• Shelf life specifications differ between parts

The substitute part 4106-S maintains identical thickness and product type but provides different planar dimensions (6.000" × 4.000" versus 12.000" × 12.000"). This substitution is valid when the application requires a smaller gasket area or when the original part dimensions exceed enclosure specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (4106-.25): Select this part when enclosure dimensions require a 12.000" × 12.000" gasket area. Both RoHS Compliant and REACH Unaffected certifications apply. Current inventory of 693 pieces supports immediate procurement.

Substitute Part Selection (4106-S): Select part 4106-S when application requirements specify a 6.000" × 4.000" gasket area. This substitute maintains identical thickness (0.500") and gasket functionality. ROHS3 Compliant and REACH Unaffected certifications apply. Higher current inventory (816 pieces) may provide procurement advantages.

Compliance Considerations: Both parts meet regulatory requirements for RoHS and REACH. The 4106-S carries ROHS3 designation, indicating compliance with the most recent RoHS directive iteration. Selection between parts should be based on dimensional fit within the target enclosure, not compliance status.

Frequently Asked Questions (FAQ)

Q: Can 4106-S substitute for 4106-.25 in all applications?

A: Substitution is valid only when the application enclosure dimensions accommodate the smaller 6.000" × 4.000" gasket area. Thickness remains identical at 0.500", ensuring equivalent sealing performance in compatible installations.

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

A: Thickness directly determines the compression force required and the sealing interface geometry. Both parts maintain 0.500" thickness, making them functionally equivalent in this critical parameter.

Q: Are there differences in shelf life between these parts?

A: The 4106-.25 does not specify shelf life data. The 4106-S specifies 60 months shelf life from date of manufacture. Storage conditions and shelf life start dates should be verified during procurement.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are REACH Unaffected. The 4106-.25 is RoHS Compliant, and the 4106-S is ROHS3 Compliant. Both designations satisfy current regulatory requirements for electronic component procurement.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Bulk packaging. No special handling or individual packaging is provided.

Q: How should dimensional compatibility be verified before substitution?

A: Measure the available gasket area in the target enclosure. The 4106-.25 requires 12.000" × 12.000" space. The 4106-S requires 6.000" × 4.000" space. Confirm that the selected part dimensions fit within the enclosure perimeter before finalizing the substitution.
