1111280503

Overview

The Molex 1111280503 is a MiniDIMM DDR2 socket designed for vertical surface mount applications. It features a 0.60mm pitch and supports 244 circuits with a maximum voltage of 1.8V. The contacts are plated with 0.76µm gold over nickel to ensure reliable signal transmission. This component includes a pick-and-place cover and utilizes a natural off-white latch mechanism. It complies with EU RoHS standards and is lead-free, suitable for high-density memory module integration in electronic devices requiring compact form factors.

Feature Summary

• Vertical surface mount design for space-constrained PCB layouts
• Gold-over-nickel contact plating for enhanced conductivity and corrosion resistance
• Integrated pick-and-place cover to protect contacts during assembly
• Natural latch mechanism for secure memory module retention

Applications

• DDR2 memory module sockets
• MiniDIMM interface connections
• High-density electronic device motherboards
• Embedded systems with limited board space

Procurement Notes

Verify the specific revision level and packaging configuration before ordering, as manufacturing updates may occur without functional changes. Confirm that the required pick-and-place cover is included in the shipment. Ensure compatibility with the target PCB footprint and mounting requirements. Check for any end-of-life notifications or recommended replacement parts if planning long-term production runs.

Selection Notes

Select this component when a vertical orientation is required for DDR2 memory modules. The 0.60mm pitch allows for high circuit density within a small footprint. Consider the 1.8V operating voltage limit when designing power delivery networks. The surface mount package simplifies automated assembly processes compared to through-hole alternatives.

Part Context

This part belongs to the MiniDIMM series, which focuses on compact memory solutions. It is distinct from standard DIMM connectors due to its reduced size and specific pin count. The series is engineered for applications where board real estate is critical, such as in mobile computing or industrial control systems requiring robust memory interfaces.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific model.
