It uses the standard DA shell size (2) with 4-40 threaded inserts for mating hardware. The 6A per-contact current rating at 125V is typical for signal and low-power circuits in this shell size — think RS-232, parallel data, or control lines inside industrial controllers, test equipment, or medical devices. The board lock and ground strap add mechanical retention during soldering and a low-impedance path to the PCB ground plane for EMI control. The 6A per-contact rating is the current each pin can carry continuously at room temperature. This is standard for D-Sub signal applications; for higher-voltage circuits, the creepage distance between pins in the DA shell layout becomes the limiting factor, not the connector itself. The UL94 V-0 rated thermoplastic housing means the connector can be used inside equipment enclosures where flame retardance is required by safety standards. The steel shell with tin plating provides RFI/EMI shielding when mated to a matching D-Sub plug with a metal backshell. The 4-40 threaded inserts accept jackscrews on the mating plug for secure, vibration-resistant connection. Termination is through-hole solder — the right-angle pins insert into the PCB and are wave-soldered. The 0.318\" (8.08mm) backset spacing means the mounting flange sits that distance from the PCB edge, which matters for panel cutout alignment in standard D-Sub openings.","metaTitle":"TE AMPLIMITE HD-20 747845-4, 15-Pin D-Sub Receptacle, 6A","metaDescription":"TE Connectivity AMPLIMITE HD-20 747845-4 D-Sub receptacle, 15 positions, right-angle solder, 6A, 125V, gold contacts, board lock, UL94 V-0.","metaKeywords":null},"attributes":{"series":"AMPLIMITE HD-20","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Cable Assemblies"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Series":"AMPLIMITE HD-20","Package":"Tray","Features":"Board Lock, Ground Strap","Wire Gauge":"-","Termination":"Solder","Contact Form":"-","Contact Type":"Signal","Mounting Type":"Through Hole, Right Angle","Connector Type":"Receptacle, Female Sockets","Contact Finish":"Gold","Flange Feature":"Housing/Shell (4-40)","Number of Rows":"2","Product Status":"Active","Voltage Rating":"125V","Backset Spacing":"0.318\\\" (8.08mm)","Connector Style":"D-Sub","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Ingress Protection":"-","Base Product Number":"747845","Dielectric Material":"Thermoplastic","Number of Positions":"15","Current Rating (Amps)":"6A","Operating Temperature":"-55°C ~ 105°C","Shell Material, Finish":"Steel, Tin Plated","Contact Finish Thickness":"30.0µin (0.76µm)","Material Flammability Rating":"UL94 V-0","Shell Size, Connector Layout":"2 (DA, A)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4500","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.45000","currency":"USD"},{"qty":10,"price":"$5.64900","currency":"USD"},{"qty":25,"price":"$5.50120","currency":"USD"},{"qty":104,"price":"$5.05760","currency":"USD"},{"qty":312,"price":"$5.02801","currency":"USD"},{"qty":520,"price":"$4.70267","currency":"USD"},{"qty":1040,"price":"$4.19987","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8bf87e66b84fb273dbe731db4fa07025.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating connector for the 747845-4?","answer":"The mating connector is a standard DA-15 D-Sub plug (male pin) with the same shell size and 4-40 threaded inserts.
