We don’t stock the HF49FD/005-1H11 from Honfa, however we do carry an alternate from Panasonic Electric Works. The original was a 5V (coil), 5A (switching), 1 Form A relay with through-hole pins in a specific inline pattern. It’s not impossible to find but most similar relay series use a different arrangement, at least from my search. Here’s a diagram from the datasheet to show what I mean:
In most relays with a footprint like this, I found that the 5.08mm and 10.16mm gaps were instead 7.62mm each, something to watch out for with this series.
The replacement I found is part number 255-5324-5-ND. It should be a drop-in replacement for the original HF49FD/005-1H11. For reference, the datasheet for the Hongfa relay can be found here: HF49FD_EN
See below for details on the 255-5324-5-ND.
