FAQ LAN Transformer: WHD20601TG
Q
What is the most important environmental difference when selecting between the similarly sized WHD20601TG and WHD20601G?
›
A
The key difference is operating temperature: WHD20601TG is rated from -40 to +85 °C, while WHD20601G is rated from 0 to +70 °C. Where cold start, outdoor temperature variation, or industrial-temperature margin is required, evaluate WHD20601TG against those limits. Even if the main mechanical dimensions match, compare the complete pin diagram and specification revision and complete high- and low-temperature link testing before substitution.
Q
Which mechanical parameters must be fixed in the WHD20601TG footprint in addition to the 2.54 mm pin pitch?
›
A
The body is 25.40 ± 0.50 mm × 10.00 ± 0.50 mm with a maximum height of 7.20 mm. Row spacing is 7.62 mm, the longitudinal pin span is 22.86 ± 0.20 mm, and the recommended hole diameter is 0.90 mm. This combination determines the actual hole locations and board area, so the footprint cannot be shared with a 2.00 mm-pitch 20PIN dual-port model.
Q
Does the -40 to +85 °C rating of WHD20601TG mean that its 25 °C electrical results need no verification across the full temperature range?
›
A
No. The electrical specifications use 25 °C as the reference test temperature, including the minimum 350 μH open-circuit inductance measured at 100 kHz, 0.1 V, and 8 mA DC bias. The -40 to +85 °C range defines the operating environment. The project must still verify link behavior, timing, and EMC at cold start, high-temperature steady state, and after temperature cycling rather than extrapolating a single room-temperature data point to the complete system.
