Board Fit and Footprint Basics
The 10129381-906002BLF: The through-hole termination with a 0.090" (2.29mm) post length suits boards up to about 1.6mm thick — typical for wave-solder assembly. The unshrouded design leaves the square pins exposed, which makes probing easy during debug but means the mating receptacle gets no polarization guide — alignment relies on the header's pin straightness and the receptacle's chamfer. For a 6-position connector that is rarely a problem.
Current, Voltage, and Temperature Ceilings
Rated 3A per contact at 110VDC. The 3A figure is the per-contact limit at room ambient. The UL94 V-0 housing means the thermoplastic body meets the flame-retardant standard required for equipment inside enclosures.
Cuttable Header — Field Flexibility
The connector type is listed as 'Header, Cuttable' — the dual-row strip can be broken to fewer positions if needed. On site, if a 6-position header is too long, you can snap off the extra pins with a pair of cutters and still use the remaining positions. That's a practical advantage for repair work where the exact position count isn't available off the shelf.
