10076443-104LF Equivalent & Substitute Parts

Part Overview

The 10076443-104LF is a 240-position RDIMM DDR3 SDRAM socket connector manufactured by Amphenol ICC (FCI). This through-hole mounted memory connector features board guides and latches, designed for DDR3 SDRAM applications per MO-269 standards. The product is currently obsolete, making identification of compatible substitute parts essential for legacy system maintenance and board redesigns. With 1058 units in stock, this connector remains available despite its discontinued status.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 10076443-104LF is determined by the following critical parameters:

• Connector Style: RDIMM vs. DIMM compatibility
• Number of Positions: Must be 240 positions
• Memory Type: DDR3 SDRAM specification
• Mounting Type: Through hole requirement
• Standards Compliance: MO-269 standard adherence
• Card Thickness: 0.050" (1.27mm) mechanical fit
• Contact Finish: Gold plating for signal integrity
• Mounting Feature: Normal, Standard - Top orientation

The substitute part 1-1932000-0 (TE Connectivity AMP Connectors) shares the same number of positions, memory type, mounting type, standards compliance, card thickness, contact finish, and mounting feature. However, the connector style differs: the main part is RDIMM while the substitute is DIMM. This distinction affects mechanical compatibility with specific memory module types, as RDIMM and DIMM modules have different physical and electrical characteristics despite both conforming to MO-269 standards.

Parameter Comparison

Engineering Selection Recommendations

The 10076443-104LF is obsolete; however, 1058 units remain in stock. For new designs or systems requiring active product support, the 1-1932000-0 from TE Connectivity AMP Connectors is available in active status with 4613 units in stock and RoHS3 compliance certification.

The primary consideration for substitution is the connector style difference: RDIMM versus DIMM. Both connectors meet MO-269 standards and share identical electrical and mechanical specifications for the 240-position, DDR3 SDRAM socket configuration. The substitute part features board lock instead of board guide, representing a minor mechanical variation in retention design.

Selection between these parts depends on the specific memory module type required by the application. RDIMM modules are designed for registered memory applications, while DIMM modules are for unbuffered memory applications. Ensure the selected connector matches the module type specified in your system design.

Frequently Asked Questions (FAQ)

Q: Can the 1-1932000-0 directly replace the 10076443-104LF?

A: Both connectors are 240-position DDR3 SDRAM sockets with identical mounting types, standards compliance, and card thickness. However, RDIMM and DIMM connectors are designed for different memory module types. Direct replacement is possible only if your system uses DIMM modules instead of RDIMM modules.

Q: What is the difference between RDIMM and DIMM connectors?

A: RDIMM (Registered DIMM) connectors are designed for registered memory modules with a register chip on the module. DIMM (Dual In-line Memory Module) connectors are for unbuffered memory modules. Both conform to MO-269 standards but are not interchangeable at the module level.

Q: Are both parts RoHS compliant?

A: The 10076443-104LF does not specify RoHS status in the provided data. The 1-1932000-0 is RoHS3 compliant. For new designs, the RoHS3 compliant substitute is recommended.

Q: What is the significance of the board guide versus board lock feature?

A: Board guide and board lock are both retention mechanisms. Board guide provides alignment support, while board lock provides positive locking. Both designs ensure secure module installation on the PCB.

Q: Are the contact finishes equivalent?

A: Both parts use gold contact finish. The main part specifies flash thickness, while the substitute specifies 15.0µin (0.38µm). Both provide adequate signal integrity for DDR3 SDRAM applications.
