Hi Zac, Thank you for your question. The RP46463 and the RP32104 are not interchangeable. The RP32104 was used in our 1700 series faucets until February 2006. Our multichoice universal rough in was introduced in February 2006 and the 17 series faucets since that time have used the RP46463. You can order this cartridge from your local retailer or wholesaler that sells Delta products. You can also order online at deltafaucet.com. Here is the link.http://www.deltafaucet.com/repairpa...
