Headers, Male Pins Procurement Notes

Verify the specific pin count configuration required for the target application, as the base part number may correspond to multiple variations. Confirm that the surface mount footprint matches the PCB layout design specifications. Ensure compatibility with standard reflow soldering profiles for lead-free assemblies. Check for any recent product change notices regarding material composition or plating specifications before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a low-profile surface mount header is required for signal-level applications up to 50V. The 2.50mm pitch offers a balance between density and spacing for general-purpose wiring. Consider the Signal Double Lock series features if enhanced mechanical retention during mating cycles is necessary. Evaluate thermal management requirements against the -30°C to 105°C operating range for the intended environment.

Headers, Male Pins Part Context

This connector is part of the broader Signal Double Lock family from TE Connectivity AMP Connectors. The series is characterized by its robust latching mechanism and versatile mounting options. Components in this line are engineered for high reliability in demanding environments, maintaining consistent electrical performance over extensive mechanical cycles. The 1-917389-3 specifically adapts these features for surface mount technology integration.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series should be verified against pin count and pitch specifications. Cross-referencing with other manufacturers requires careful evaluation of footprint dimensions and latching mechanisms. Ensure that any alternative component meets the same UL94 V-0 flammability rating and temperature operating limits.
