Amphenol ICC 10076443-101LF DDR3 RDIMM Memory Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 10076443-101LF is a 240-position RDIMM DDR3 SDRAM socket connector designed for through-hole PCB mounting. This connector is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, board redesigns, and inventory management. The part features board guides and latches for secure module retention, with gold-plated contacts and standard top-mount configuration suitable for server and workstation memory applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 10076443-101LF is determined by the following critical parameters:

• Connector Style: Must be DIMM or RDIMM (both are 240-position DDR3 socket variants)
• Number of Positions: Must be 240 to maintain electrical and mechanical compatibility
• Memory Type: Must be DDR3 SDRAM
• Standards Compliance: Must conform to MO-269
• Mounting Type: Must be through-hole PCB mounting
• Card Thickness: Must accommodate 0.050" (1.27mm) module thickness
• Contact Finish: Gold plating required for signal integrity
• Mounting Feature: Must be normal, standard top-mount configuration

The TE Connectivity AMP Connectors part 1-1932000-7 qualifies as a substitute based on these parameters. While it is specified as a DIMM connector (versus RDIMM), both connector styles accommodate 240-position DDR3 modules with identical electrical pinouts and mechanical dimensions per MO-269 standard. The functional difference between RDIMM and DIMM sockets is the presence of a register on the module itself, not the socket connector, making them electrically and mechanically interchangeable at the connector level.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1-1932000-7 is a qualified substitute for the obsolete Amphenol ICC 10076443-101LF based on the following engineering criteria:

Functional Equivalence: Both connectors meet MO-269 standard specifications for 240-position DDR3 SDRAM sockets with identical electrical pinouts, mechanical dimensions, and contact characteristics.

Active Product Status: The TE Connectivity part is actively manufactured and in stock (759 units available), whereas the Amphenol part is obsolete. This ensures long-term availability and supply chain continuity.

Compliance and Certifications: The TE Connectivity substitute is ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and board revisions.

Mechanical Compatibility: Both connectors feature identical card thickness accommodation (0.050"), mounting type (through-hole), and top-mount configuration, ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1932000-7 DIMM socket replace the Amphenol 10076443-101LF RDIMM socket?

A: Yes. Both are 240-position DDR3 SDRAM sockets conforming to MO-269 standard. The RDIMM versus DIMM designation refers to the module type (registered versus unbuffered), not the socket connector itself. The electrical pinouts and mechanical interfaces are identical, making them directly interchangeable at the connector level.

Q: Are there any PCB layout or footprint changes required?

A: No. Both connectors share identical through-hole mounting dimensions, card thickness accommodation (0.050"), and top-mount configuration. Direct PCB footprint compatibility is maintained.

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

A: The TE Connectivity 1-1932000-7 has 759 units in stock as new original inventory, providing immediate availability for production and repair applications.

Q: Does the substitute part meet current environmental standards?

A: Yes. The TE Connectivity part is ROHS3 compliant, meeting current environmental regulations. The original Amphenol part's RoHS status was not specified.

Q: Are contact finish specifications identical?

A: Yes. Both connectors feature gold-plated contacts. The TE Connectivity part specifies 15.0µin (0.38µm) contact finish thickness, ensuring consistent signal integrity and corrosion resistance.
