RF EMI Absorbing Sheet 85000072 Equivalent & Substitute Parts

Part Overview

The Laird Technologies EMI model 85000072 is an RF EMI absorbing sheet manufactured from ECCOSORB® JCS silicone rubber with pressure sensitive adhesive (PSA). The part measures 12.000" × 12.000" × 0.080" and operates across a temperature range of -70°C to 177°C. This product is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure continued availability for applications requiring RF EMI absorption in electronic assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF EMI absorbing sheets is determined by the following parameters: planar dimensions (length and width), thickness, material composition, adhesive type, operating temperature range, and regulatory compliance status.

The substitute parts listed below maintain the same 12.000" × 12.000" planar dimensions and operating temperature range (-70°C to 177°C) as the original part 85000072. Both substitute parts are manufactured by Laird Technologies EMI and utilize pressure sensitive adhesive (PSA) attachment methods. The key differentiators are material composition (silicone elastomer versus silicone rubber) and thickness variation.

Critical Parameters for Substitution:

• Planar dimensions: 12.000" × 12.000"
• Operating temperature: -70°C to 177°C
• Adhesive system: Pressure Sensitive Adhesive (PSA)
• Regulatory compliance: ROHS3 Compliant

Parameter Comparison

Engineering Selection Recommendations

Part 85095081 provides the closest functional equivalence to the original 85000072. Both parts maintain identical planar dimensions (12.000" × 12.000") and thickness (0.080"), with operating temperature ranges of -70°C to 177°C. Part 85095081 is manufactured from silicone elastomer rather than silicone rubber and carries active product status with full ROHS3 compliance and REACH unaffected designation. This part is the preferred direct replacement.

Part 85095031 offers an alternative configuration with reduced thickness (0.030" versus 0.080"). This part maintains the same planar dimensions and operating temperature range but provides a thinner profile. Selection of this part is appropriate when space constraints or application-specific requirements necessitate reduced material thickness while maintaining RF EMI absorption functionality.

Both substitute parts are manufactured by the original equipment manufacturer (Laird Technologies EMI) and carry active product status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can part 85095081 directly replace part 85000072?

A: Yes. Part 85095081 maintains identical planar dimensions (12.000" × 12.000"), equivalent thickness (0.080"), identical operating temperature range (-70°C to 177°C), and identical adhesive type (PSA). Both parts are ROHS3 compliant. The material composition differs (silicone elastomer versus silicone rubber), but both are silicone-based elastomeric materials suitable for RF EMI absorption applications.

Q: What is the primary difference between 85095031 and 85095081?

A: The primary difference is thickness. Part 85095031 measures 0.030" (0.76mm) thick, while part 85095081 measures 0.080" (2.03mm) thick. Both maintain the same 12.000" × 12.000" planar dimensions and operating temperature range. Selection depends on application space constraints and EMI absorption requirements.

Q: Why is the original part 85000072 classified as obsolete?

A: Part 85000072 has been superseded by the Eccosorb™ JCS-Next series (parts 85095031 and 85095081). The JCS-Next series represents the current generation of Laird Technologies EMI absorbing sheets and is the manufacturer's recommended replacement.

Q: Are all three parts ROHS3 compliant?

A: Yes. Parts 85000072, 85095031, and 85095081 are all ROHS3 compliant. Additionally, parts 85095031 and 85095081 carry REACH unaffected status.

Q: What packaging is available for the substitute parts?

A: Both substitute parts 85095031 and 85095081 are supplied in bulk packaging.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -70°C to 177°C.

Q: What is the shelf life for these absorbing sheets?

A: All three parts have a shelf life of 12 months from the date of shipment.
