Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 10076443-103LF is determined by the following critical parameters:

• Connector Style: Must support DIMM or RDIMM architecture for DDR3 memory modules
• Position Count: Exactly 240 positions required for electrical and mechanical alignment
• Memory Type: DDR3 SDRAM compatibility mandatory
• Mounting Type: Through-hole mounting required for PCB integration
• Standards Compliance: MO-269 standard adherence ensures mechanical and electrical interoperability
• Card Thickness: 0.050" (1.27mm) specification must be maintained
• Contact Finish: Gold plating required for reliable electrical contact
• Mounting Feature: Normal, Standard - Top configuration for proper board integration

The substitute part 1932000-4 (TE Connectivity AMP Connectors) meets all critical substitution criteria, with the distinction of supporting DIMM architecture rather than RDIMM, while maintaining full electrical and mechanical compatibility for DDR3 SDRAM applications.

Parameter Comparison

Engineering Selection Recommendations

The 1932000-4 from TE Connectivity AMP Connectors serves as a direct functional substitute for the obsolete 10076443-103LF. Both connectors maintain identical electrical specifications for 240-position DDR3 SDRAM applications and comply with MO-269 standards. The primary distinction is the connector style designation (DIMM versus RDIMM), which does not affect electrical or mechanical compatibility for standard DDR3 module insertion.

The 1932000-4 offers the additional advantage of active product status and RoHS compliance certification, making it suitable for new designs and legacy system replacements where regulatory compliance is required. Both connectors feature gold contact finishes and identical card thickness specifications, ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1932000-4 directly replace the 10076443-103LF on existing PCBs?

A: Yes. Both connectors share identical 240-position configurations, through-hole mounting, MO-269 compliance, and 0.050" card thickness. PCB footprints are mechanically and electrically compatible.

Q: What is the difference between RDIMM and DIMM connector styles?

A: RDIMM (Registered DIMM) and DIMM (Unbuffered DIMM) refer to module types, not connector physical specifications. Both connector styles accommodate 240-position DDR3 SDRAM modules with identical electrical and mechanical interfaces per MO-269 standards.

Q: Does the 1932000-4 meet current regulatory requirements?

A: Yes. The 1932000-4 is RoHS compliant and carries active product status, meeting current environmental and regulatory standards for component procurement.

Q: Are the latching mechanisms compatible between these connectors?

A: Both connectors feature latching mechanisms. The 10076443-103LF includes board guides and latches, while the 1932000-4 includes board lock and latches. Both designs ensure secure module retention and are mechanically compatible with standard DDR3 module retention features.

Q: What is the contact finish specification for both connectors?

A: Both connectors feature gold contact finishes. The 10076443-103LF specifies flash thickness, while the 1932000-4 specifies 15.0µin (0.38µm) thickness. Both finishes provide equivalent electrical performance for DDR3 SDRAM applications.
