MK 251 38 G

Headers, Male Pins Overview

The MK 251 38 G is a male pin header connector manufactured by Fischer Elektronik. It features a 2-row configuration with 38 total contacts, providing a robust connection interface for electronic assemblies. The component utilizes a standard 2.54 mm (0.100 inch) pitch spacing between pins, ensuring compatibility with common PCB layouts. Designed for through-hole mounting, the connector supports right-angle installation to facilitate efficient board-to-board or wire-to-board connections. The housing is constructed from black insulating material rated UL94 V-0 for flammability safety. Electrical performance includes an operating temperature range of -40°C to +163°C, suitable for diverse environmental conditions.

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix and contact count against official Fischer Elektronik documentation before procurement. Ensure the selected variant matches the required row count and pitch specifications for the target PCB footprint. Confirm that the through-hole right-angle form factor aligns with mechanical constraints. Cross-reference the UL94 V-0 rating and temperature range with application requirements to guarantee operational reliability under expected thermal conditions.

Headers, Male Pins Selection Notes

Select this component when a 2-row, 38-position male header is required for through-hole mounting. The 2.54 mm pitch ensures broad compatibility with standard connectors and cables. Consider the right-angle orientation for space-constrained designs where vertical clearance is limited. Verify that the -40°C to +163°C operating range meets the environmental demands of the end-use application. Ensure the black V-0 rated housing satisfies any relevant safety or aesthetic standards.
