Product details

20-Position Breakaway Header – 2.54mm Pitch, Gold Contacts

The mating contacts are gold-plated at 15.0µinch (0.38µm) over phosphor bronze, while the solder tails receive a thicker 74.8µinch (1.90µm) tin finish.

Obsolete – Sourced per RFQ, No Direct Successor

Molex has marked the 10-89-1201 as Obsolete. 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.

Frequently asked questions

Is the Molex 10-89-1201 obsolete, and what is the replacement?

No direct pin-compatible replacement has been announced. 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.

Where can I buy the 10-89-1201 and get a price?

The 10-89-1201 is sourced through independent distribution against an RFQ. Submit an RFQ for your target quantity and lead-time requirement.

What is the difference between 10-89-1201 and 10-89-1202?

The 10-89-1201 is a 20-position header; the 10-89-1202 is a 24-position header in the same C-Grid 8624 series. Both share the 2.54mm pitch, dual-row layout, and gold-plated mating contacts. The position count is the only difference — the board footprint scales accordingly.
