If you're replacing a connector on an existing RS-232 cable or a serial port card, the pin-for-pin match is straightforward: same shell, same position count, same thread. The solder termination is field-serviceable with a basic iron — no crimp tool needed, just tin the wires and flow them into the cups. The 2-row layout keeps the pin spacing at the standard 0.108-inch (2.74 mm) row-to-row pitch, which matches the footprint for any DE-9 PCB layout. Grounding indents on the shell mate with the receptacle's dimples to create a low-impedance shield path before the signal pins engage.","metaTitle":"TE Connectivity 4-1393479-3 AMPLIMITE HD-20 D-Sub Plug","metaDescription":"TE Connectivity AMPLIMITE HD-20 D-Sub plug, 9-position DE-9 shell, right-angle solder termination, gold contacts, RoHS compliant.","metaKeywords":null},"attributes":{"series":"AMPLIMITE HD-20","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Cable Assemblies"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"-","Series":"AMPLIMITE HD-20","Package":"Bulk","Features":"Grounding Indents","Wire Gauge":"-","Termination":"Solder","Contact Form":"-","Contact Type":"Signal","Mounting Type":"Through Hole, Right Angle","Connector Type":"Plug, Male Pins","Contact Finish":"Gold","Flange Feature":"Housing/Shell (4-40)","Number of Rows":"2","Product Status":"Active","Voltage Rating":"-","Backset Spacing":"-","Connector Style":"D-Sub","lifecycle_stage":"unknown","Contact Material":"-","Ingress Protection":"-","Base Product Number":"1393479","Dielectric Material":"-","Number of Positions":"9","Current Rating (Amps)":"-","Operating Temperature":"-","Shell Material, Finish":"-","Contact Finish Thickness":"-","Material Flammability Rating":"-","Shell Size, Connector Layout":"1 (DE, E)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.87000","currency":"USD"},{"qty":10,"price":"$5.98700","currency":"USD"},{"qty":25,"price":"$5.82960","currency":"USD"},{"qty":50,"price":"$5.67220","currency":"USD"},{"qty":100,"price":"$5.32550","currency":"USD"},{"qty":250,"price":"$5.29400","currency":"USD"},{"qty":500,"price":"$4.97890","currency":"USD"},{"qty":1000,"price":"$4.44319","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the pinout of 4-1393479-3?","answer":"It follows the standard DE-9 RS-232 pinout: 9 positions in two rows, shell size 1 (DE, E).
