ASIC Repair Fitment & Bill of Materials

Quick answer

This matrix denormalizes "what parts fit THIS miner" into one row per bench-serviceable Bitcoin ASIC model (10 models, S9 through S21 XP plus a WhatsMiner cross-reference). Each row joins the control board, hash-board chip and chips-per-board, the stock PSU and its output connector, the NEMA wall plug, the fan size/count/connector, the PIC, EEPROM and temperature-sensor reference designators, the heatsink class, and the architecture-specific list of likely-failed component classes — so a tech can scope a repair, order the right parts and avoid ordering a PIC for a model that never had one.

Use it before you order parts or open a board. It is a denormalized JOIN of the live D-Central dc/v1 datasets, grounded in the Mining Bible; any cell the Bible does not confirm is marked "unverified" rather than guessed. Free CSV/JSON under CC BY 4.0. Designators and counts vary by board revision — always verify against your specific board.

Notes: The S9 stacks its 21 voltage domains in series from the ~12V rail with no discrete boost or per-domain LDO stage, so boost-converter, LDO-regulator, MP2019-buck and level-shifter classes do NOT apply. pic_refdes null: a per-board PIC16F1704 is present (I2C 0x50+chain) but the Bible does not enumerate its designator. eeprom_refdes null: no EEPROM was populated on the live-probed S9 (0x50-0x54 empty). temp_sensor null: count/refdes not enumerated for the S9.

Confidence: medium (high on chip/PSU/fan; board-level refdes not enumerated for the S9 in the Bible)

Notes: psu_connector null: APW9 supplies a high-current DC output but its connector layout is not enumerated in the Bible. nema_plug null: the S17/T17 is not in the asic-power-requirements dataset; it is a 200-240V-only unit (APW9) — a dedicated 240V circuit (NEMA 6-20 by convention) is typical, confirm per cordset. pic/eeprom/temp refdes null: present per generation but designators not enumerated. The ~18.5V domain stack may run without a discrete boost stage (APW9 supplies 14.5-21V directly), so boost-converter is omitted as unverified.
