104703

Overview

The TE Connectivity / ERNI 104703 is a hard metric receptacle connector featuring 125 positions arranged in five rows. It utilizes a 2.00 mm (0.079 inch) pitch and employs press-fit termination for vertical board mounting. The component is designed as a female type B connector without shielding, providing high-density interconnect capabilities for rigid PCB applications.

Feature Summary

• High-density 125-position configuration across five rows
• Vertical press-fit termination for direct PCB insertion
• Type B hard metric design without integrated shielding

Applications

• High-pin-count backplane interconnects
• Industrial control system motherboards
• Telecommunications infrastructure hardware

Procurement Notes

Verify the specific manufacturing revision and RoHS compliance status directly with TE Connectivity or authorized distributors before procurement. Confirm that the press-fit pin dimensions align precisely with the target PCB drill specifications to ensure mechanical integrity and electrical continuity during assembly.

Selection Notes

Select this component when a high-density, unshielded vertical interface is required. Ensure the application environment does not demand EMI shielding, as this model lacks protective casing. Validate that the host board supports press-fit technology rather than through-hole soldering for proper installation.

Part Context

This part belongs to the TE Connectivity Erni hard metric connector family, which specializes in robust, high-reliability interconnect solutions for demanding industrial and telecommunications environments. The series emphasizes mechanical stability and high pin counts within compact form factors.

Replacement Considerations

Consult official TE Connectivity substitution guides for verified equivalents. Generic hard metric connectors may differ in pin geometry or locking mechanisms; do not assume interchangeability without verifying mechanical fit and electrical ratings against the original datasheet.
