10140903-1420BLF

Edgeboard Connectors Overview

The Amphenol ICC (FCI) part number 10140903-1420BLF is an EHPCE VR PF series edgeboard connector. It features a dual-edge female configuration with 34 total positions, comprising 20 signal and 14 power contacts. The connector is designed for through-hole termination using press-fit technology. It utilizes gold GXT™ plating on the contacts and has a black housing made of thermoplastic material. The unit supports a card thickness of 0.062 inches (1.57mm) and is classified as non-specified for dual-edge applications.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design supporting both signal and power transmission within a single interface.
• Press-fit termination method ensures secure mechanical attachment to the board without soldering.
• Gold GXT™ contact plating provides reliable conductivity and corrosion resistance for high-performance connections.

Edgeboard Connectors Applications

• High-density backplane interconnects in telecommunications infrastructure
• Server and storage system motherboard connections
• Industrial control panel signal and power distribution

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official datasheet to confirm pin count and plating specifications. Ensure compatibility with the target PCB stack-up and card thickness requirements. Confirm that the press-fit termination process aligns with the assembly capabilities of the manufacturing facility. Cross-reference the RoHS compliance status and material change notifications prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-reliability connection is required for dual-edge cards in space-constrained environments. The press-fit option eliminates soldering thermal stress on the board. Evaluate the 34-position capacity against system I/O and power rail requirements. Consider the EHPCE series performance characteristics for signal integrity and durability in demanding operational conditions.
