Lifecycle

Current status not announced as near end of life based on public information, actual availability can vary by region and date

In-family alternatives Vishay WSLP3921 series with other ohmic values and tolerances, Vishay WSL3921 series lower power class typically around 5 W if your design allows

Higher current alternatives Vishay WSBS series metal shunts if you need heavier current or different mounting

Cross-brand options examples include Bourns CSS2H 3920 family, Stackpole CSS series, Yageo metal current shunts in similar sizes, verify form fit function and power derating in your design
