March 7 (Reuters) - ** India's electronics sector, especially smartphone exports, may suffer if U.S. imposes 16%-20% reciprocal tariffs, says Bernstein

** Market impact may be limited as most electronics exporters, except EMS firms, are unlisted

** Since Trump's threat of reciprocal tariff on February 13, auto .NIFTYAUTO and pharma .NIPHARM stocks lost 6% and 4.6%, respectively, more than Nifty's .NSEI 2% fall

** NIPHARM faces the biggest risk, with $8 billion in U.S. exports and minimal imports

** Bernstein says India holds strong bargaining power due to U.S. dependence on Indian generics, lack of alternatives except China

** Expects India to lower duties for Tesla TSLA.O, Harley-Davidson HOG.N to protect auto component makers from U.S. higher tariffs

** Says import duty cut may not hurt domestic car makers due to high pricing of U.S. cars

** Adds agriculture faces less risk as U.S. exports are small despite high tariff differences
