1546551-9

Overview

The TE Connectivity AMP Connectors part number 1546551-9 is a wire-to-board terminal block featuring a 3-position configuration with side entry orientation. It utilizes a 3.5mm pitch spacing for compact circuit board integration. The component is designed for through-hole mounting and solder termination to ensure secure electrical connections. This specific model belongs to the terminal block category, providing a reliable interface between PCB traces and external wiring harnesses in electronic assemblies.

Feature Summary

• Side entry design facilitates convenient wire access from the lateral direction of the terminal block housing.
• 3.5mm pitch spacing allows for dense circuit board layout while maintaining adequate contact separation.
• Through-hole solder termination ensures robust mechanical fixation and stable electrical conductivity on printed circuit boards.

Applications

• General purpose wire-to-board interconnections
• Industrial control panel wiring
• Consumer electronics assembly

Procurement Notes

Verify the exact position count and pitch against the schematic before procurement. Confirm that the side entry orientation matches the enclosure design constraints. Ensure the soldering process parameters are compatible with the terminal material specifications to maintain joint integrity during assembly.

Selection Notes

Select this component when a low-profile, three-wire connection point is required with lateral wire access. The 3.5mm pitch offers a balance between current carrying capacity and board space efficiency compared to finer pitches. Consider the side entry feature if top-entry connectors conflict with adjacent components or enclosure height restrictions.

Part Context

This part is part of TE Connectivity's broader terminal block portfolio, which includes various position counts and pitch options. The 1546551 series shares common housing materials and termination methods within its family, allowing for modular design approaches across different product lines requiring similar connectivity standards.

Replacement Considerations

Direct substitutes must match the 3-position count, 3.5mm pitch, and side entry orientation. Verify compatibility with existing PCB footprints and mating wire gauges. Cross-reference with other manufacturers' terminal blocks offering identical dimensional and electrical characteristics.
