Inferred sibling
Believed to share an original design with this part. Not a manufacturer claim; the reasoning is given with each.
HR 46177 — HR Diemen's 2011 equivalence catalogue maps LG 6174Z-1017D to HR 46455 (no data held) and 6174Z-1017H to HR 46177 (schematic, 30.6 kV, B+ pin 2, COL pin 1; fitted to Apple CRT iMacs, M5521). The -D is reported as an iMac G3 part, which is why the -H is the sibling chosen. The suffix letter alone proves little: the 6174Z-1017 range covers at least eight HR codes, and of the three with data, -A (HR 46187) matches the -H closely but -E (HR 46255) has a different pin-out and 25.5 kV. Treat the HR 46177 sheet as a lead and check pin-out and anode rating on the part. Source
