Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0879660002 is determined by strict equivalence across the following critical parameters:

• Connector Style & Position Count: Both main and substitute parts must be DIMM connectors with exactly 240 positions to ensure mechanical and electrical compatibility with DDR2 SDRAM modules.
• Memory Type: DDR2 SDRAM specification is mandatory for signal integrity and timing compliance.
• Standards Compliance: MO-237 standard adherence ensures pin configuration and electrical characteristics match.
• Mounting Configuration: Surface mount orientation with standard top-mounted feature is required for PCB layout compatibility.
• Physical Dimensions: Card thickness of 0.050" (1.27mm) and contact specifications must align for proper module insertion and retention.
• Contact Specifications: Gold plating at 30.0µin (0.76µm) thickness ensures consistent electrical performance and corrosion resistance.

The Amphenol ICC (FCI) part 10080289-10003LF meets all these criteria and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison
