Tin is good for moderate mating cycles (50-100 mates typical) in clean indoor environments — not for high-vibration or corrosive atmospheres where gold would be specified. No official successor or pin-compatible cross-reference is listed. The base number 1986718 covers the series; variants differ by position count and plating. For a direct replacement, stick with the same base number and verify the position count and tail length. Unshrouded design means no plastic shroud around the pins — the mating receptacle must align visually or use its own keying. This saves board space but offers no polarisation against mis-mating.","metaTitle":"1986718-4 TE Connectivity 4-Pin Header, 3.50mm Pitch, Active","metaDescription":"1986718-4 TE Connectivity AMP Connectors — 4-position vertical unshrouded header, 3.50mm pitch, tin-plated contacts, 2 A / 150 V.
