This saves board space but means the mating connector must be aligned carefully to avoid stubbing on the exposed pins. ## Voltage and Current — What the Ratings Mean Rated 250 VAC and 350 VDC — the DC ceiling is higher because the creepage path under steady DC stress is less prone to tracking than under AC. This covers both line-voltage AC and typical 24–48 VDC control circuits. For a given wire gauge, derate per the temperature rise curve in the full product drawing. Operating temperature range is -20°C to 95°C, which suits indoor equipment and climate-controlled cabinets but not engine compartments or outdoor direct-sun enclosures without additional derating. Contact length - post is 0.142\" (3.60 mm), which determines the PCB thickness range the header can accommodate. Overall contact length is 0.551\" (14.00 mm), with the mating pin length at 0.295\" (7.49 mm). ROHS3 compliant and packaged in bulk — no tape-and-reel, so it ships loose in a bag or tube. Suitable for hand-load or low-volume assembly. ## How It Compares to Similar Headers Compared to the 1-292164-1 (CT series, 2.00 mm pitch, 11 positions, right-angle, 4-wall shrouded, detent lock), the 172732-2 has a wider 2.50 mm pitch, fewer positions, vertical orientation, and single-wall shrouding — it is a simpler, lower-density part for basic 2-wire connections. The 1376366-8 (.025 series, 2.20 mm pitch, 8 positions, right-angle, 4-wall shrouded, rated 5 A) offers more positions and a fixed current rating, but the 172732-2's vertical orientation and latch holder suit a different board layout and fastening requirement.","metaTitle":"172732-2 TE Connectivity EI Header, 2 Pos, 2.5 mm","metaDescription":"172732-2 TE Connectivity AMP EI series header, 2 positions, 0.098\" (2.50 mm) pitch, single row, shrouded 1 wall, latch holder, through-hole, tin contacts.","metaKeywords":null},"attributes":{"series":"EI","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"EI","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 1 Wall","Termination":"Kinked Pin, Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"1","Pitch - Mating":"0.098\\\" (2.50mm)","Product Status":"Active","Voltage Rating":"250VAC, 350VDC","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Natural","Insulation Height":"0.409\\\" (10.40mm)","Ingress Protection":"-","Base Product Number":"172732","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"2","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.142\\\" (3.60mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-20°C~95°C","Mated Stacking Heights":"-","Overall Contact Length":"0.551\\\" (14.00mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.295\\\" (7.49mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5300","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.53000","currency":"USD"},{"qty":10,"price":"$1.33300","currency":"USD"},{"qty":100,"price":"$1.19130","currency":"USD"},{"qty":500,"price":"$0.99274","currency":"USD"},{"qty":1000,"price":"$0.85091","currency":"USD"},{"qty":5000,"price":"$0.75448","currency":"USD"},{"qty":10000,"price":"$0.73746","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/72462b32556a6c2949cae1bf6a2a63df.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pinout of 172732-2?","answer":"No internal wiring or circuit assignment is defined by the connector — it carries whatever signals or power the board routes to the two pins."},{"question":"Is 172732-2 equivalent to 1-292164-1?","answer":"No. The 1-292164-1 is a CT series header with 2.00 mm pitch, 11 positions, right-angle orientation, 4-wall shrouding, and a detent lock.
