The Molex 1501772040 is a 4-circuit plug housing from the EconoLatch 150177 series, designed as a wire-to-wire or wire-to-panel interconnect. It carries a 0.145" (3.68mm) pitch in a dual-row layout, which gives each circuit enough spacing for moderate current without crowding the harness.
What Contacts Fit This Housing
This plug housing accepts male pin crimp terminals (contact type: Male Pin). The crimp termination allows you to attach the terminals to discrete wires before inserting them into the housing cavities. Confirm the wire gauge range from the terminal datasheet to match your harness build.
The 0.145" (3.68mm) pitch is wider than the common 0.100" (2.54mm) or 3.00mm pitch used on signal connectors. That extra spacing gives more room for larger wire gauges and reduces the risk of flashover between adjacent circuits in higher-voltage applications. The dual-row layout with 0.145" (3.68mm) row spacing means the connector body is roughly 0.29" wide across the two rows — a compact footprint for a 4-circuit power or signal run.
