Hengwei Electronics is a manufacturer of power relays, specifically in the JQC-3F series. Digi-Key has been asked to supply these and while we do not currently carry this manufacturer we do have suitable replacements to offer.
Digi-Key currently carries four manufacturers which supply relay series’ to replace the JQC-3F series by Hengwei such as [ORWH-SH-105D1F,000] which is a 5V, 1 Form C, relay by TE.(https://www.digikey.com/en/products/detail/te-connectivity-potter-brumfield-relays/ORWH-SH-105D1F000/4925028). Other variations can be viewed via the following link. https://www.digikey.com/short/z17vj0
These have been cross referenced from the datasheet for the JQC-3F series. https://pdf.voron.ua/files/pdf/relay/JQC-3F(T73).pdf
