For a replacement, look within the Micro-MaTch family for a current 18-position, 2-row, 2.54 mm pitch receptacle with tin plating. A board respin may be required if no exact fit exists. ## What the Tin Plating Means for Field Service Tin-plated contacts are rated for fewer mating cycles than gold — typically 25–50 cycles before the plating wears and fretting corrosion starts. In a telecom cabinet that gets opened quarterly, that's about 12 years of service before the contact resistance drifts. The forked contact geometry is field-repairable: you can re-pin the receptacle on site with the matching crimp terminal and a basic hand tool, as long as the housing hasn't cracked from UV or thermal cycling.","metaTitle":"1-2178711-8 TE Connectivity Micro-MaTch 18-Pin Receptacle","metaDescription":"1-2178711-8 TE Connectivity AMP Connectors Micro-MaTch receptacle, 18 positions, 2.54mm pitch, tin-plated contacts.
