Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 11-37FSC-NI-16 is determined by the following critical parameters:

• Dimensional Compatibility: Width (0.380"/9.65mm) and length (16.000"/406.40mm) must match exactly to ensure proper fit within existing enclosure designs
• Material Specification: Beryllium copper construction is required to maintain electrical conductivity and mechanical spring properties for EMI gasket function
• Plating System: Nickel plating ensures corrosion resistance and consistent contact resistance in RF applications
• Attachment Method: Adhesive-backed configuration must be preserved for installation compatibility
• Operating Temperature: Substitute must support the full -55°C to 121°C range or the maximum operating temperature of the original design
• Compliance Standards: RoHS compliance status must be verified for regulatory alignment

The substitute part 0097054118 from Laird Technologies EMI meets these core substitution criteria while offering active product status and current manufacturing availability.

Engineering Selection Recommendations

The 0097054118 from Laird Technologies EMI is the qualified substitute for the obsolete 11-37FSC-NI-16. Selection is based on the following engineering factors:

• Dimensional Alignment: Critical dimensions (width, length) are identical. The height variance of 0.010" (0.26mm) represents a 9.1% increase and falls within acceptable mechanical tolerance for gasket compression in standard EMI shielding enclosures.
• Material and Plating Continuity: Both parts utilize beryllium copper with nickel plating, ensuring equivalent electrical performance and environmental durability.
• Compliance Status: The substitute maintains RoHS compliance and is manufactured to current regulatory standards, eliminating obsolescence risk.
• Active Manufacturing Status: The substitute is actively produced by Laird Technologies EMI, ensuring long-term supply chain availability and consistent quality control.
• Thermal Performance: Maximum operating temperature of 121°C matches the original specification, confirming suitability for the intended application range.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the 11-37FSC-NI-16?

A: The original part is classified as obsolete and no longer in active production. The 0097054118 provides functional equivalence while ensuring continued availability and compliance with current manufacturing standards.

Q: Are the dimensional differences between the two parts significant?

A: The height difference of 0.010" (0.26mm) is within normal gasket compression tolerances. Width and length dimensions are identical, ensuring proper fit in existing enclosure designs. The slight height increase may result in marginally higher compression force, which is acceptable for EMI gasket applications.

Q: Will the substitute part maintain the same electrical performance?

A: Yes. Both parts use beryllium copper with nickel plating, providing equivalent electrical conductivity and contact resistance characteristics required for RF and wireless shielding applications.

Q: Is the substitute part RoHS compliant?

A: Yes. The 0097054118 is RoHS compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Can the substitute be used as a direct drop-in replacement?

A: Yes, for standard EMI gasket applications. The adhesive attachment method, material composition, and critical dimensions ensure compatibility with existing enclosure designs. The marginal height variance does not compromise functional performance in typical shielding applications.

Q: What is the availability status of the substitute part?

A: The 0097054118 is actively manufactured by Laird Technologies EMI with current inventory availability, eliminating supply chain risk associated with the obsolete original part.
