Norcold doesn't offer a replacement for the DC Heater 638216, and it has been discontinued by Norcold. If there's one left, it'll show on the product page. See our N3150 parts page. The N3150 is discontinued too, and Norcold's replacement is the Norcold N4150. See our Norcold replacement guide.
Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you. You can also browse www.rvfridgeguys.com.
