M20-7861042

Overview

The Harwin M20-7861042 is a single-row socket assembly from the M20 series, featuring 10 positions with a 2.54 mm pitch. Designed for surface mount technology, it utilizes a push-pull locking mechanism and accepts bottom or top insertion. The connector employs phosphor bronze contacts with gold plating on the mating interface and tin plating on the tail. It operates within a temperature range of -40°C to 105°C, carries an UL94 V-0 flammability rating, and supports a rated current of 3A per contact at 250V.

Feature Summary

• Push-pull locking system ensures secure mechanical retention during mating cycles
• Dual insertion capability allows flexible PCB layout orientation
• Gold-plated mating surfaces provide reliable electrical conductivity
• High-temperature resistant PA6T insulation material

Applications

• General purpose board-to-board interconnects
• Surface mount electronic assemblies requiring high reliability
• Industrial control modules

Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to obsolescence notices. Confirm RoHS compliance status via official documentation before integration. Ensure storage conditions maintain integrity of the tin-plated tails against oxidation prior to soldering processes.

Selection Notes

Select this component when a single-row SMT socket with push-pull retention is required. Verify that the mating header matches the 2.54 mm pitch and compatible contact geometry. Consider the specific insertion direction (top or bottom) needed for the target PCB design constraints.

Part Context
