I'm trying to add products to the cart in woomerce, but am getting a persistent error Uncaught ReferenceError: wc_add_to_cart_params is not defined.

Have used this approach many times before without issue, has wc_add_to_cart_params been removed from woomerce? If so what is the replacement?

My code is as follows:

  var productId = form.find('input[name=product_id]').val();
  var variationId = form.find('input[name=variation_id]').val();
  var qty = form.find('input[name=qty]').val();

  // Data array
  var data = {
    action: 'woomerce_ajax_add_to_cart',
    product_id: productId,
    variation_id: variationId,
    quantity: qty,
  };

  // Ajax function
  $.ajax({
    type: 'post',
    url: wc_add_to_cart_params.ajax_url,
    data: data,
  });

Thanks

In case this es up for anyone else, it appears the add-to-cart.min.js only loads if 'Enable AJAX add to cart buttons on archives' is enabled in the WC settings. This resolves the issue for me.

Your syntax is correct but the point is from where it is called. If it is a external js file then enqueue it in footer.
