The shell size is 5 (DD), the standard layout for 50-pin high-density D-subs. The press-fit termination means the contacts are pressed into plated through-holes — no solder wicking, no reflow profile to manage. That makes this part a fit for backplane assemblies or any build where solderless assembly and field rework are priorities. ## Press-Fit Termination — The Assembly Implication Press-fit contacts avoid the thermal cycle of wave or reflow solder. The PCB hole diameter must match the press-fit zone of the compliant pin — a standard plated through-hole for a 0.040-inch square post is typical, but the exact finished hole size lives in the TE application drawing. The press-fit joint is gas-tight and passes the same reliability tests as solder, with the advantage that a damaged contact can be staked out and replaced without desoldering. ## Mating Half and Field Fit The flange features 4-40 threaded inserts for the jackscrew lock — the same UNC 4-40 thread used across the HD-20 family. The mating plug must also be press-fit or solder-cup terminated; the shell interface is independent of the termination style. Gold-on-copper-alloy contacts on both halves handle repeated mate-unmate cycles without fretting corrosion. ## Temperature Range and Flammability The steel shell is tin-plated for corrosion resistance and EMI shielding continuity when the mating plug's shell contacts the ground indents.","metaTitle":"TE Connectivity 5747144-2 AMPLIMITE HD-20 D-Sub","metaDescription":"TE Connectivity 5747144-2 AMPLIMITE HD-20 D-Sub receptacle, 50 positions, 3 rows, press-fit termination, gold contacts, -55°C to 105°C.","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":"Black","Series":"AMPLIMITE HD-20","Package":"Bulk","Features":"-","Wire Gauge":"-","Termination":"Press-Fit","Contact Form":"-","Contact Type":"Signal","Mounting Type":"Through Hole","Connector Type":"Receptacle, Female Sockets","Contact Finish":"Gold","Flange Feature":"Housing/Shell (4-40)","Number of Rows":"3","Product Status":"Active","Voltage Rating":"-","Backset Spacing":"-","Connector Style":"D-Sub","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Ingress Protection":"-","Base Product Number":"5747144","Dielectric Material":"Thermoplastic","Number of Positions":"50","Current Rating (Amps)":"-","Operating Temperature":"-55°C ~ 105°C","Shell Material, Finish":"Steel, Tin Plated","Contact Finish Thickness":"-","Material Flammability Rating":"UL94 V-0","Shell Size, Connector Layout":"5 (DD, D)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$48.2400","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$48.24000","currency":"USD"},{"qty":10,"price":"$39.82100","currency":"USD"},{"qty":25,"price":"$37.01280","currency":"USD"},{"qty":50,"price":"$34.97080","currency":"USD"},{"qty":100,"price":"$34.20500","currency":"USD"},{"qty":250,"price":"$33.94980","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/fcdbadc5f7b7fe6f2cd84be709637131.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating connector for 5747144-2?","answer":"Any standard AMPLIMITE HD-20 50-position D-Sub plug (male pin) with shell size DD and 4-40 threaded jackscrew flanges will mate with this receptacle."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5747144-2","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/5747144-2 when reusing this data.
