1-1871058-4

Overview

The 1-1871058-4 is a vertical PCI Express card edge connector manufactured by TE Connectivity AMP Connectors. It features 164 positions arranged in two rows with a 1.0mm (0.039 inch) contact pitch. Designed for board-to-card applications, this female connector utilizes gold or gold-palladium plating on the contacts to ensure reliable signal transmission. The housing is black and supports a maximum rated current of 1.1A per contact.

Feature Summary

• Vertical orientation design facilitates standard PCB mounting configurations
• Dual-row configuration provides high-density connectivity for PCIe interfaces
• Gold or gold-palladium contact plating ensures corrosion resistance and stable electrical performance

Applications

• PCI Express card edge connections
• High-density board-to-card interconnects
• Electronic devices requiring reliable PCIe interface integration

Procurement Notes

Verify the specific contact plating option required for your application, as datasheets indicate availability in both gold and gold-palladium variants. Confirm that the vertical form factor aligns with your mechanical constraints. Ensure compatibility with the 1.0mm pitch specification when designing the mating card edge. Cross-reference the manufacturer part number with official TE Connectivity documentation to confirm current production status and lead times.

Selection Notes

Select this component for applications demanding robust PCI Express connectivity with a 1.0mm pitch. The vertical style suits space-constrained boards where height is not the primary limitation. Consider the 164-position count for bandwidth requirements. Verify thermal management needs against the 1.1A per contact rating. Ensure the chosen plating variant meets environmental durability standards for the target deployment.

Part Context

This connector belongs to the PCI Express / PCI connector category within TE Connectivity's portfolio. It serves as a critical interface component for modern electronic systems, bridging expansion cards to motherboards or backplanes. The 164-position layout supports high-speed data transfer protocols essential for contemporary computing hardware.

Replacement Considerations

Consult official TE Connectivity substitution guides for verified alternatives. Generic equivalents may not match the precise 1.0mm pitch or mechanical locking features. Validate any substitute against the original 164-position requirement and vertical mounting specifications before implementation.
