The dual-row layout uses the standard 0.050-inch pitch with 0.100-inch row-to-row spacing — the footprint for high-density D-sub signal interconnects. The 1 A per-contact rating at 30 V places this connector firmly in the signal-density class — think parallel data buses, control lines, or low-power I/O, not power distribution. The 28 positions pack into a shell size that is physically smaller than a standard DB-25, so the current limit reflects the contact density and the IDC termination's current-carrying capacity. ## Shielding and Environmental Ratings The steel shell with tin-nickel finish is the EMI shield — it grounds through the D-sub shell to the mating receptacle's shield, containing radiated emissions from the ribbon cable. This is the cable-end plug — free-hanging (in-line) mount, mates with a standard AMPLIMITE.050 III receptacle (solder-cup or PCB-mount). The IDC termination accepts ribbon cable and terminates all 28 conductors simultaneously when pressed with a hand tool or press.","metaTitle":"TE AMPLIMITE .050 III 5749621-3, 28-Pos D-Sub Plug, IDC","metaDescription":"TE Connectivity AMPLIMITE .050 III 5749621-3 D-sub plug, 28 positions, IDC ribbon cable termination, shielded steel shell, gold contacts, 1 A, 30 V.","metaKeywords":null},"attributes":{"series":"AMPLIMITE .050 III","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 .050 III","Package":"Bulk","Features":"Shielded","Wire Gauge":"-","Termination":"IDC, Ribbon Cable","Contact Form":"-","Contact Type":"Signal","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pins","Contact Finish":"Gold","Flange Feature":"-","Number of Rows":"2","Product Status":"Active","Voltage Rating":"30V","Backset Spacing":"-","Connector Style":"D-Type","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Ingress Protection":"-","Base Product Number":"5749621","Dielectric Material":"Thermoplastic","Number of Positions":"28","Current Rating (Amps)":"1A","Operating Temperature":"-55°C ~ 105°C","Shell Material, Finish":"Steel, Tin-Nickel Plated","Contact Finish Thickness":"-","Material Flammability Rating":"UL94 V-0","Shell Size, Connector Layout":"0.050 Pitch x 0.100 Row to Row"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.4000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.40000","currency":"USD"},{"qty":10,"price":"$12.11900","currency":"USD"},{"qty":25,"price":"$11.79880","currency":"USD"},{"qty":50,"price":"$11.34980","currency":"USD"},{"qty":100,"price":"$10.51620","currency":"USD"},{"qty":250,"price":"$10.45208","currency":"USD"},{"qty":500,"price":"$10.06732","currency":"USD"},{"qty":1000,"price":"$8.97723","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8962fe773415a34be1c511becb51da42.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating connector for the 5749621-3?","answer":"This plug mates with a standard AMPLIMITE.050 III receptacle — the mating half is a 28-position D-sub receptacle with female sockets, available in solder-cup or PCB-mount termination."},{"question":"Is the 5749621-3 shielded?","answer":"Yes, the 5749621-3 has a shielded steel shell with a tin-nickel finish that provides EMI containment for the ribbon cable assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5749621-3","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/5749621-3 when reusing this data.
