Key Parameters

Substitute Part Grouping Explanation

Substitution of RF EMI conductive foam sheets is determined by the following critical parameters:

Primary Substitution Criteria:

• Product category: Conductive Foam Sheet (RF EMI application)
• Series compatibility: EcoFoam™ series
• Adhesive configuration: Single-sided conductive adhesive
• Shape: Rectangular
• Operating temperature range: Must encompass or exceed the original specification
• Regulatory compliance: ECCN and HTSUS classification alignment

Secondary Considerations:

• Dimensional compatibility: Length, width, and thickness must be evaluated against specific application requirements
• Product status: Active status preferred for long-term availability
• Shelf life and storage conditions: Consistency with handling and inventory management

The CF710KA00644064 is identified as a substitute component within the EcoFoam™ series, sharing the same manufacturer, product type, adhesive configuration, and regulatory classification. Both parts are rectangular conductive foam sheets with single-sided adhesive backing designed for RF EMI shielding applications.

Parameter Comparison

Engineering Selection Recommendations

Obsolescence Status: The CF720AB01001778 is classified as obsolete. The CF710KA00644064 is an active product within the same EcoFoam™ series and manufacturer ecosystem, providing a path forward for designs requiring RF EMI conductive foam sheet solutions.

Regulatory Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8529.90.9800) classifications, ensuring equivalent export control and tariff treatment. The substitute part includes documented RoHS compliance, providing additional regulatory assurance for applications subject to RoHS requirements.

Temperature Performance: The substitute part extends the upper operating temperature limit from 70°C to 85°C, providing enhanced thermal margin for applications operating in elevated temperature environments.

Dimensional Differences: The substitute part presents different dimensional characteristics: increased length (16.000" vs. 7.000"), reduced width (0.250" vs. 0.394"), and reduced thickness (0.039" vs. 0.080"). These dimensional variations require evaluation against specific application geometry and EMI shielding requirements. The substitute material can be cut or configured to match original dimensional specifications where necessary.

Availability: Current inventory status shows 825 pieces of the substitute part available, compared to the obsolete status of the original part. This availability supports procurement continuity and supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can CF710KA00644064 directly replace CF720AB01001778 in existing designs?

A: Direct replacement depends on application-specific dimensional and performance requirements. Both parts are EcoFoam™ series conductive foam sheets with single-sided adhesive backing and identical regulatory classifications. The substitute part has different length, width, and thickness dimensions. If the original design requires the specific 7.000" × 0.394" × 0.080" dimensions, the substitute material can be cut or configured to match. If the application can accommodate the substitute's 16.000" × 0.250" × 0.039" dimensions, direct substitution is feasible.

Q: What are the key compatibility parameters for EcoFoam™ conductive foam substitution?

A: Substitution within the EcoFoam™ series is based on: (1) product type—conductive foam sheet for RF EMI applications; (2) adhesive configuration—single-sided conductive adhesive; (3) shape—rectangular; (4) operating temperature range—must meet or exceed application requirements; (5) regulatory classification—ECCN and HTSUS alignment; (6) manufacturer—Laird Technologies EMI.

Q: Does the substitute part offer improved performance characteristics?

A: The CF710KA00644064 extends the operating temperature range to -40°C ~ 85°C, compared to the original -40°C ~ 70°C specification. This provides a 15°C increase in maximum operating temperature. The substitute part also includes documented RoHS compliance. Thickness and width are reduced in the substitute part, which may affect EMI shielding effectiveness depending on application requirements.

Q: Are there shelf life or storage differences between these parts?

A: Both parts specify 12-month shelf life and identical storage temperature of 73.4°F (23°C). Storage and handling procedures are equivalent.

Q: What is the significance of the product status difference?

A: The original part (CF720AB01001778) is obsolete, indicating it is no longer manufactured or supported by Laird Technologies EMI. The substitute part (CF710KA00644064) is active, meaning it is currently manufactured, supported, and available for procurement. This status difference is critical for long-term design support and supply chain continuity.
