Rated at 6A per contact and 125V, it handles standard signal-level and moderate power duty within a DB-25 shell size (3, DB, B layout). The contacts are gold flash over brass — sufficient for routine mating cycles in equipment that stays assembled, though not specified for frequent field reconnection. A tin-plated steel shell with grounding indents provides EMI shield continuity, bleeding chassis current before the signal pins engage. ## What the 6A and Gold Flash Ratings Mean for Your Assembly For a 25-position plug carrying signal-level loads, the margin is generous. The gold flash provides a corrosion-resistant mating surface for moderate cycle counts — think a few dozen mates over the equipment life, not a daily-cycled panel interface. If your application requires frequent reconnection or operates in a corrosive environment, a connector with thicker gold plating would be a better fit. ## Grounding Indents and Shell Construction The tin-plated steel shell includes grounding indents — these are dimples on the shell face that make electrical contact with the mating receptacle's shell before the signal pins engage. This provides a low-impedance path for shield current and helps manage EMI in assemblies where the D-sub is the cable entry point. The shell uses unthreaded mounting holes (housing/shell flange feature), so you will need a separate nut or a threaded receptacle for panel mounting. The through-hole solder tails are designed for PCB mounting; the contact spacing and row pitch match the standard 0.108-inch (2.74 mm) between rows and 0.090-inch (2.29 mm) between contacts. For a complete mated pair, order the matching AMPLIMITE HD-20 receptacle (e.g., 5745968-4's counterpart in the same series). The unthreaded flange means the plug is typically secured with 4-40 jack-screws on the receptacle side or a separate nut.","metaTitle":"TE Connectivity 5745968-4 AMPLIMITE HD-20 D-Sub Plug, 25-Pos","metaDescription":"TE Connectivity 5745968-4 AMPLIMITE HD-20 D-Sub plug, 25 positions, 6A/125V, gold flash contacts, through-hole solder, UL94 V-0.","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":"Tube","Features":"Grounding Indents","Wire Gauge":"-","Termination":"Solder","Contact Form":"-","Contact Type":"Signal","Mounting Type":"Through Hole","Connector Type":"Plug, Male Pins","Contact Finish":"Gold","Flange Feature":"Housing/Shell (Unthreaded)","Number of Rows":"2","Product Status":"Active","Voltage Rating":"125V","Backset Spacing":"-","Connector Style":"D-Sub","lifecycle_stage":"unknown","Contact Material":"Brass","Ingress Protection":"-","Base Product Number":"5745968","Dielectric Material":"Polyester","Number of Positions":"25","Current Rating (Amps)":"6A","Operating Temperature":"-55°C ~ 105°C","Shell Material, Finish":"Steel, Tin Plated","Contact Finish Thickness":"Flash","Material Flammability Rating":"UL94 V-0","Shell Size, Connector Layout":"3 (DB, B)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.8800","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.88000","currency":"USD"},{"qty":10,"price":"$8.93100","currency":"USD"},{"qty":25,"price":"$8.69520","currency":"USD"},{"qty":50,"price":"$8.36440","currency":"USD"},{"qty":100,"price":"$7.75000","currency":"USD"},{"qty":250,"price":"$7.70276","currency":"USD"},{"qty":500,"price":"$7.41924","currency":"USD"},{"qty":1000,"price":"$6.61588","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/34f413e851dac7302cc03b2c894dc2d7.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5745968-4","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/5745968-4 when reusing this data.
