For a BOM that requires an active alternative, the closest functional match within the C-Grid 8624 family would be a similar 20-position, 2.54mm-pitch unshrouded header — but the exact plating, contact length, and insulation height may differ. A board-spin or a revised mating half may be needed. The 0.090\" (2.29mm) insulation height leaves clearance for component placement under the header body.","metaTitle":"Molex 10-89-1201 C-Grid 8624 Header – 20 Pos, 2.54mm Pitch","metaDescription":"Molex 10-89-1201 obsolete 20-position unshrouded header, 2.54mm pitch, gold-plated contacts.

For a BOM requiring an active part, a functionally similar 20-position, 2.54mm-pitch unshrouded header from the C-Grid 8624 series may fit, but the exact contact finish and dimensions should be verified against the board layout."},{"question":"Where can I buy the 10-89-1201 and get a price?","answer":"The 10-89-1201 is sourced through independent distribution against an RFQ.

Both share the 2.54mm pitch, dual-row layout, and gold-plated mating contacts.
