The insulator stands 0.090" (2.29mm) off the board surface — a low profile that leaves clearance for adjacent components. Because it's unshrouded, the header mates with standard KK254 crimp housings or IDC receptacles — no keying or polarization, so orientation is set by the board layout.
Sourcing buyers need cost data for BOM pricing and budget approval.
Critical for procurement to identify authorized distributors and avoid counterfeit parts.
Lead time and availability affect production scheduling and delivery commitments.
Design engineers must verify fit, pin pitch, and electrical ratings before using the part.
Finding compatible substitutes helps mitigate supply chain risk and cost optimization.
Technicians replacing a failed connector need pin assignment to ensure correct wiring.
