1546556-4

Overview

The TE Connectivity AMP Connectors part number 1546556-4 is a wire-to-board terminal block connector. It features four positions with a 3.50mm pitch. The component utilizes a through-hole mounting style and is designed with a 55-degree angle relative to the board. It is classified as a stackable terminal block.

Feature Summary

• Stackable design for vertical expansion
• Angled contact configuration
• Through-hole termination

Applications

• Wire-to-board interconnections
• Terminal block assemblies
• Stacked circuit board layouts

Procurement Notes

Verify the specific datasheet for the 1546556-4 variant, as some sources indicate this product may be discontinued or have limited availability. Confirm RoHS compliance status directly from the manufacturer's documentation before procurement, as conflicting information exists regarding its regulatory status. Ensure the 55-degree angle specification matches the mechanical requirements of the target assembly.

Selection Notes

Select this component when a low-profile, angled wire-to-board connection is required in a stackable configuration. The 3.50mm pitch accommodates standard wire gauges for general electronics. Verify that the through-hole footprint fits the PCB layout constraints and that the 55-degree orientation does not interfere with adjacent components or housing structures.

Part Context

This component belongs to the TE Connectivity AMP Connectors line of wire-to-board terminal blocks. It is distinct from header connectors and quick-connect terminals. The 1546556 series typically includes variants with different pin counts and angles, such as the 8-position version.

Replacement Considerations

Check for alternative part numbers within the same family, such as 1546556-8, which offers an 8-position configuration. Verify if other manufacturers offer compatible 3.50mm pitch, 55-degree angled terminal blocks with similar stacking capabilities.
