ASIC Miner Replacement Connectors

Replacement Connectors and Headers for ASIC Miner Repair

Connectors and headers are the failure points nobody thinks about until a contact burns, a socket cracks, or a pin gets pushed back during reassembly. This collection covers every replacement plug, socket, and header you need for component-level repair on Antminer, Whatsminer, Avalon, Iceriver, Goldshell and Innosilicon hardware — power input connectors (C19, C20, P13, P14, P33, P34, SA-30), signal sockets (2×7 pin, 9-pin D-sub, 18-pin), and conductive copper sheets for high-current Avalon repairs. Buy just the connector, not a whole new cable, and save 80 % on simple plug-replacement repairs.

When you need a connector or header (not a full cable)

Four common scenarios where a replacement connector is the right part :

• Burned PSU input socket — when the C19 or P14 socket on your APW17 / APW12 / P232B has been arcing, the contact surfaces are damaged. Replace just the socket, keep the rest of the PSU.
• Cracked or bent power output plug — P13 6-pin or P33 6-pin plugs on Antminer S21 / S19j XP power cords can crack from repeated insertion. Order the plug only, splice onto existing cable.
• Damaged control-board signal socket — 2×7 (14-pin) curved needle sockets and 18-pin signal headers on Innosilicon and Avalon control boards get bent when force-mated. Replacement sockets are inexpensive component-level fixes.
• Hydro-miner connector failure — Whatsminer hydro SA-30 male plug or female socket can leak or oxidise in cooling-fluid environments. Replace just the connector pair.

What's in this collection

• Whatsminer / MicroBT power connectors — C19 16A power socket (250V AC) for M30 / M31 / M32 / M50 PSU rebuilds, C19 female 250V IEC320 AC connector for PDU integration, SA-30 male plug for hydro / oil immersion power cord assemblies.
• Avalon / Canaan signal connectors — 10-pin 1×10 curved needle socket for Avalon power supply repair, conductive copper sheet for Avalon 1166 / 1246 miner power connection rework, conductive copper strip for Avalon 1346 / 1326 PSU connection.
• Innosilicon signal connectors — 2×7 (14-pin) control board signal socket compatible with Innosilicon and Avalon series.
• D-sub repair connectors — DS1037-09MNAKT74-0CC 9-pin male D-sub right-angle 3A through-hole mount for legacy control board ports.

Why source connectors from LYS Shenzhen

Three reasons component-level repair shops and farm engineering teams source connectors from us :

• Genuine OEM-grade parts — connectors match the mechanical specs and current rating of the original Bitmain / MicroBT / Avalon parts ; not generic substitutes that fail under load.
• Bulk pricing on small parts — a single connector costs $0.06 to $3, but at fleet scale (50+ miners) reorder volumes matter. Quote-based pricing for repair shops and farms.
• Worldwide shipping with DDP option for US and EU customers — small parts ship fast and clear customs without the friction of larger PSU shipments.

Frequently asked questions

Can I really save money by replacing just the connector instead of the whole cable ?
Yes, on the cable side : a P13 plug alone costs $2.70 vs $8-15 for a full P13-to-region power cord. The catch is you need crimping and / or soldering skills to splice the new connector onto the existing cable. For PSU input sockets, replacement is usually a soldering job inside the PSU enclosure — repair-shop work, not end-user.

Are these connectors rated for the right current and voltage ?
Yes. C19 sockets are rated 16A 250V. P13 / P14 connectors match Bitmain APW17 / APW11 ratings. SA-30 hydro connectors are rated for the 220-277V high-power hydro miner range. Specs are listed on each product page.

My miner uses a connector not in your collection — can you source it ?
Yes. Most ASIC manufacturer connectors are sourced through standard electronics suppliers in Shenzhen. Share the part number stamped on the connector body (or a clear photo of both sides) and we'll quote the replacement.

Do you supply matching crimping tools for these connectors ?
We stock the connectors themselves. For crimping tools and dies, we can point you to compatible third-party tooling on request, or send the cable assembled with the new connector pre-crimped if you prefer.
