4-146250-0

Headers, Male Pins Overview

The TE Connectivity AMP Connectors part number 4-146250-0 is a vertical male pin header connector belonging to the AMPMODU Mod II series. It features an 80-position configuration with a single row design and a 0.100-inch (2.54 mm) contact spacing. The connector utilizes through-hole termination for secure board mounting and employs square-shaped contacts made from copper alloy. The housing is constructed from black liquid crystal polymer (LCP) material, rated UL94 V-0 for flammability. Contact plating consists of tin-lead on both mating and tail sections, each with a thickness of 100.0 microinches (2.54 micrometers). The unit supports a rated current of 3A and operates within a temperature range of -65°C to 105°C.

Headers, Male Pins Procurement Notes

Verify the specific lot date code and RoHS compliance status upon order confirmation, as tin-lead plating may indicate non-compliance with modern environmental directives depending on the manufacturing batch. Confirm that the supplier provides original manufacturer documentation or authorized distribution certificates to ensure authenticity. Check for any recent product change notices (PCN) regarding material substitutions or packaging updates that might affect assembly processes or regulatory approvals.

Headers, Male Pins Selection Notes

Select this component when a high-count, low-profile vertical header is required for dense PCB layouts. Ensure the mating receptacle matches the 2.54 mm pitch and square contact profile. Consider the thermal limitations of the tin-lead plating if soldering temperatures exceed standard lead-free profiles without proper adjustment. Verify that the 3A current rating aligns with the electrical load requirements of the target application circuits.
