302-S401

Headers, Male Pins Overview

The On Shore Technology Inc. 302-S401 is a vertical male pin header connector designed for through-hole mounting on printed circuit boards. It features a rectangular configuration with 40 positions arranged in a single row, utilizing a 2.54mm (0.100 inch) pitch to ensure precise alignment with mating components. The connector supports a voltage rating of 250V and a current capacity of 3A, suitable for standard electronic signal and power distribution applications. Constructed with shrouded walls for enhanced safety and stability, it includes a keying slot to prevent incorrect insertion during assembly. The unit operates reliably within a temperature range of -40°C to 105°C, ensuring durability under varying environmental conditions.

Headers, Male Pins Procurement Notes

Verify the specific contact plating finish and insulation material ratings against project requirements before ordering. Confirm that the 40-position layout matches the target PCB footprint exactly. Ensure the operating temperature range meets the environmental specifications of the end-use application. Cross-reference the keying slot orientation to guarantee correct polarity during assembly processes.

Headers, Male Pins Selection Notes

Select this component when a robust, vertically oriented header with positive locking features is required. The shrouded design minimizes the risk of short circuits and accidental pin damage during handling. Consider the 3A current rating and 250V voltage limit to ensure compliance with system electrical standards. Evaluate the through-hole mounting method against available space and mechanical stress constraints in the final enclosure.

Headers, Male Pins Part Context

This part belongs to the 302 series of rectangular connectors manufactured by On Shore Technology Inc. The series offers various position counts and configurations tailored for diverse electronic assembly needs. As a male pin header, it serves as the stationary interface counterpart to female socket connectors, facilitating modular system designs and serviceable hardware architectures.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 40-position count, 2.54mm pitch, and vertical through-hole form factor. Verify compatibility regarding shroud height, keying slot location, and terminal plating specifications. Generic headers may lack the specific mechanical retention or electrical ratings provided by this model.
