AT-1451-861-XX

Overview

The AT-1451-861-XX is a .5mm Slim Low-Profile Micro Receptacle Connector manufactured by Samtec Inc. It features a 140-pin, 2-row configuration with a 3.5mm height and K Pad termination. The contacts are plated with 10µin Gold/Tin for enhanced conductivity and corrosion resistance. Designed for high-density applications, this component utilizes tape and reel packaging to facilitate automated surface mount assembly processes.

Feature Summary

• Ultra-low profile design with 3.5mm height
• High-density 140-pin two-row receptacle
• Gold/Tin contact plating for reliability
• Tape and reel packaging for SMT

Applications

• High-density board-to-board interconnects
• Space-constrained electronic assemblies
• Automotive infotainment systems
• Industrial control modules

Procurement Notes

Verify the specific suffix code required for your application, as the XX placeholder indicates customizable options such as mating pin length or plating variations. Confirm that the 3.5mm stack height aligns with your mechanical constraints. Ensure compatibility with the corresponding male header from the same product family to maintain signal integrity and mechanical stability during operation.

Selection Notes

Select this connector when minimal vertical space is available but high I/O density is required. The 0.50mm pitch allows for significant pin counts in a compact footprint. Consider the K Pad termination style for robust surface mounting. Evaluate the mating partner's height and pin configuration to ensure proper engagement without excessive stress on the PCB pads.

Part Context

This component belongs to Samtec’s Slim Low-Profile Micro series, designed for applications demanding high performance in restricted volumes. The series offers various row counts and heights to accommodate different system architectures while maintaining consistent electrical characteristics across the product line.

Replacement Considerations

Direct substitutes must match the 0.50mm pitch, 140-pin count, and 2-row layout. Verify that alternative connectors support the same 3.5mm height and K Pad termination method to ensure mechanical fit and soldering process compatibility without redesigning the PCB footprint.
