The mating surface carries 1.00 µinch (0.025µm) gold over copper alloy — a light flash finish. This is adequate for occasional reconnects (tens of cycles) in lab, test, or low-service applications. For field equipment cycled quarterly or in corrosive environments, a thicker gold (15 µinch or higher) would be the safer choice; this part is best suited for one-time assembly or infrequent disconnection. In a vibration environment, the mating pair can separate if the cable is tugged — a locking latch or shroud would add mechanical security. For bench-top or stationary equipment, this is rarely an issue. ## Current and Voltage Ceilings The 110 VDC voltage rating is a conservative creepage-and-clearance limit for the 2.54mm pitch and unshrouded layout. The lower bound suits cold storage or outdoor telecom cabinets; the upper bound is below the solder reflow peak but fine for wave-solder assembly. ## Cuttable Header Flexibility The connector type is listed as 'Header, Cuttable' — the 24-position strip can be broken to shorter lengths (e.g., 20, 16, 10 positions) using the snap-off grooves between positions. This lets one part number serve multiple BOM line items, reducing the number of unique SKUs in the storeroom. The break leaves a clean edge; the remaining pins retain full electrical and mechanical integrity. ## Peer Comparison: 24 vs 20 Positions The 10129381-920003BLF drops to 20 positions on the same dual-row layout. For a BOM that needs 20 circuits, the 24-position strip can be cut down; for 24 circuits, the 924001BLF is a drop-in if the shorter pin length fits the mating socket depth.","metaTitle":"10129381-924003BLF Amphenol ICC (FCI) EconoStik™ 24-Pin","metaDescription":"10129381-924003BLF Amphenol ICC (FCI) EconoStik™ header, 24 positions, 0.100\" (2.54mm) pitch, gold flash, unshrouded, through-hole, RoHS.","metaKeywords":null},"attributes":{"series":"EconoStik™ 10129381","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board or Cable","Series":"EconoStik™ 10129381","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header, Cuttable","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"110VDC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"10129381","Insulation Material":"Thermoplastic","Number of Positions":"24","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"-","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"3A","Operating Temperature":"-55°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.538\\\" (13.67mm)","Contact Finish - Mating":"Gold","Contact Length - Mating":"0.318\\\" (8.08mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"1.00µin (0.025µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.50000","currency":"USD"},{"qty":10,"price":"$0.43400","currency":"USD"},{"qty":100,"price":"$0.35800","currency":"USD"},{"qty":500,"price":"$0.31128","currency":"USD"},{"qty":1000,"price":"$0.25681","currency":"USD"},{"qty":5000,"price":"$0.22568","currency":"USD"},{"qty":10000,"price":"$0.21012","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/40b29260c807f4763ede4a3ef97aed66.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 10129381-924003BLF shrouded or unshrouded?","answer":"Unshrouded — the header has no plastic shroud around the pins.
