Molex 0348404030 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0348404030 is an 8-position rectangular connector plug housing from the MX150 34840 series, designed for panel mount and bulkhead applications. This connector features a 0.138" (4.60mm) pitch with 2 rows and a 0.236" (6.00mm) row spacing, utilizing crimp termination and twist latch fastening. The housing is constructed from glass-filled syndiotactic polystyrene (SPS) in gray and meets IP67K protection standards.

The 0348404030 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this connector type is specified.
