Frequently asked questions
What is the pinout of 280371-1?
The 280371-1 is a single-row, 4-position header with all positions loaded. Pin 1 is typically marked by a square pad or chamfer on the housing; the remaining pins are in-line at 0.100" spacing.
What is the closest functional second-source for 280371-1?
The 280372-1 is identical except for 6 positions instead of 4. Both share the same pitch, current rating, voltage, shrouding, and locking. For a 4-position requirement, 280371-1 is the direct part.
