WHDG30201G 10/100BASE-TX LAN Transformer

No. Row spacing on the WHDG30201G is 8.50 mm against 10.16 mm on the WHDG30101G and the WHDG30102G, so the three cannot share one drill pattern.

Body width differs too: 10.84 mm here against 12.50 mm on the other two. Length, height, pitch, span and hole diameter are common to all three. The Pitch field shown in the 10/100 BASE-T range does not distinguish row spacing, so a parametric search groups them together — confirm row spacing against the drawing rather than inferring it from that grouping.

No. The electrical block is identical across all three triple-port 100M parts.

OCL, insertion and return loss, cross talk, common-mode rejection, isolation, operating range and storage range are common to the WHDG30201G and the other two, and none of them supports PoE. The choice between them therefore rests on mechanical fit alone — the WHDG30201G has the narrower body and the tighter row spacing. All three are listed in the 10/100 BASE-T range.

Equipment needing three 100M ports, installed indoors, with the ports powered locally.

Typical uses are small access switches, multi-port expansion on industrial PCs and in-building network terminals. All three qualifiers come from the WHDG30201G datasheet: 0 °C to +70 °C makes it an indoor commercial grade, no PoE support means the ports cannot draw power over the cable, and the through-hole package means wave soldering. The temperature limit is the one most easily overlooked. Wide-temperature and PoE options are listed in the 10/100 BASE-T range.
