The high-density layout packs 44 signal contacts into a shell size that normally carries 25 positions, saving panel space without shrinking the contact pitch below what field-termination tools can handle. ## Right-Angle Solder Termination with Board Lock The board lock feature — a pair of metal tabs that solder into plated through-holes — takes the mechanical strain off the signal pins during cable flex and vibration. This is the same retention approach used in industrial control panels where the D-sub sees frequent connect-disconnect cycles. ## 15µin Gold Plating for Field-Service Reliability Gold plating keeps the signal path stable through repeated mating cycles. ## 3A per Contact — Signal Duty, Not Bus Power Rated 3A per contact, the 2311770-2 is a signal-density connector, not a power interconnect. The 44 contacts share the shell's thermal budget, so derate the total current if the ambient temperature approaches the 105°C upper limit. For a typical 24 AWG signal circuit, 3A is plenty of headroom for digital I/O, serial data, or low-power analog signals. Mates with any AMPLIMITE HD-22 high-density D-sub plug (44-position, 3-row) using the standard 4-40 threaded insert. The shell size is 3 (DB, B) high density — the same footprint as a standard DB-25 shell, but with the extra row of contacts.","metaTitle":"TE AMPLIMITE HD-22 2311770-2, 44-Position High-Density D-Sub","metaDescription":"2311770-2: TE AMPLIMITE HD-22 high-density D-sub receptacle, 44 positions, 3 rows, right-angle solder, 15µin gold, board lock, UL94 V-0.","metaKeywords":null},"attributes":{"series":"AMPLIMITE HD-22","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Cable Assemblies"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Series":"AMPLIMITE HD-22","Package":"Bulk","Features":"Board Lock","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":"3","Product Status":"Active","Voltage Rating":"-","Backset Spacing":"0.350\\\" (8.89mm)","Connector Style":"D-Sub, High Density","lifecycle_stage":"unknown","Contact Material":"Brass","Ingress Protection":"-","Base Product Number":"2311770","Dielectric Material":"Polybutylene Terephthalate (PBT), Glass Filled","Number of Positions":"44","Current Rating (Amps)":"3A","Operating Temperature":"-55°C ~ 105°C","Shell Material, Finish":"Steel, Nickel Plated","Contact Finish Thickness":"15.0µin (0.38µm)","Material Flammability Rating":"UL94 V-0","Shell Size, Connector Layout":"3 (DB, B) High Density"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.9400","priceTiers":[{"qty":1,"price":"$15.94000","currency":"USD"},{"qty":10,"price":"$15.60400","currency":"USD"},{"qty":25,"price":"$15.18960","currency":"USD"},{"qty":50,"price":"$14.44240","currency":"USD"},{"qty":100,"price":"$13.03140","currency":"USD"},{"qty":250,"price":"$12.94836","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/e1334feba2b92eadc95b5824509553fe.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/2311770-2/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/2311770-2","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/2311770-2 when reusing this data.
