Replace product title with SKU in product category page

Hi Woocommerce team,

I use this code to change product title in category page to H3 tag:

//change product title to h3 on category page
if ( ! function_exists( 'woocommerce_template_loop_product_title' ) ) {
    function woocommerce_template_loop_product_title() {
        echo '<h3 class="woocommerce-loop-product__title">' . get_the_title() . '</h3>';
    }
}

Now i’d like to replace product title with SKU in category page, while still remain the product title in single product page.

I have tried many code on searching but none of them works. Please help me!!!

Thanks.
