Key Parameters

Substitute Part Grouping Explanation

The substitute part 21510100 qualifies as an equivalent based on the following substitution criteria:

Material Compatibility: Both the main part (18150086) and substitute (21510100) utilize silicone rubber as the base material for RF EMI absorption, ensuring functional equivalence in electromagnetic interference suppression applications.

Geometric Compatibility: The substitute maintains a square configuration with dimensions of 12.000" × 12.000" (304.80mm × 304.80mm), providing dimensional compatibility within standard tolerance ranges for RF absorber sheet applications. The 0.008" (0.20mm) dimensional variance is negligible for typical mounting and integration scenarios.

Product Series Alignment: Both parts belong to the ECCOSORB® family of RF absorbing materials, confirming manufacturer-validated functional equivalence within the same product line.

Active Status: The substitute part 21510100 maintains active product status with current inventory availability, addressing the obsolescence of the original part.

Compliance Certification: The substitute part carries RoHS3 compliance certification and EAR99 ECCN classification, meeting current regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 21510100 is the designated equivalent for applications currently utilizing 18150086. Selection is based on the following engineering criteria:

Functional Equivalence: Both parts employ silicone rubber RF absorbing material within the ECCOSORB® product family, confirming electromagnetic performance compatibility.

Dimensional Compatibility: The square geometry and nominal 12-inch dimensions of the substitute part align with the original part specifications within standard manufacturing tolerances applicable to RF absorber sheets.

Regulatory Compliance: The substitute part 21510100 carries active RoHS3 compliance certification, meeting current environmental and regulatory requirements. The original part status as obsolete indicates it no longer meets current compliance standards.

Supply Chain Continuity: The substitute part maintains active product status with documented inventory availability, ensuring reliable procurement for ongoing applications.

Packaging Consideration: The substitute is supplied in bulk packaging, which may require adjustment to existing procurement and inventory management procedures.

Frequently Asked Questions (FAQ)

Q: Why is part 18150086 being discontinued?

A: Part 18150086 is classified as obsolete by the manufacturer. The substitute part 21510100 provides equivalent RF EMI absorption functionality with current regulatory compliance and active production status.

Q: Are the dimensional differences between 18150086 and 21510100 significant?

A: The dimensional variance of 0.008" (0.20mm) between the 12.008" original and 12.000" substitute is within standard manufacturing tolerances for RF absorber sheet applications and does not affect functional performance or mechanical integration in typical mounting configurations.

Q: What is the thickness specification for part 18150086?

A: The thickness specification for the original part 18150086 is not provided in the available technical documentation. The substitute part 21510100 specifies a thickness of 0.064" (1.63mm).

Q: Does the substitute part meet current compliance requirements?

A: Yes. Part 21510100 carries RoHS3 compliance certification and EAR99 ECCN classification, meeting current regulatory standards. The original part 18150086 does not specify compliance certifications.

Q: What is the difference between ECCOSORB® DSF and ECCOSORB® SF series?

A: Both series are silicone rubber-based RF absorbing materials within the ECCOSORB® product family. The specific performance characteristics of each series are determined by their respective formulations. Both provide RF EMI absorption functionality suitable for equivalent applications.

Q: Is the bulk packaging of part 21510100 compatible with existing procurement processes?

A: The substitute part is supplied in bulk packaging rather than the unspecified packaging of the original part. Procurement and inventory management procedures may require adjustment to accommodate bulk packaging requirements.

Q: Can part 21510100 be used as a direct replacement in existing designs?

A: Part 21510100 provides functional equivalence for RF EMI absorption applications. The square geometry and nominal 12-inch dimensions align with the original part. Design verification should confirm that the 0.064" (1.63mm) thickness specification is compatible with the intended application mounting and integration requirements.
