Jacuzzi 6541-383 Filter Cartridge
Jacuzzi OEM number • 60 sq ft • 6.75″ OD × 15.5″ long
6541-383 is Jacuzzi's number for this cartridge, not a part you have to buy from Jacuzzi. The filter itself is a 60 square foot cartridge measuring 6.75 inches across and 15.5 inches long, and Pleatco, Unicel, and Filbur all build it. If you read 6541-383 off an old cartridge or found it in your manual, any of the numbers below drops into the same housing.
Fitment notes
The open-top sibling of the PJW60TL-F2S. Same 6-3/4 by 15-1/2 inch body and same 2 inch SAE threaded bottom, but the top is open with slots instead of carrying a moulded handle, and it holds 60 sq ft against the handled version's 52. Unicel notes that its 6CH-961 needs an injection moulded semi-circular handle, which is not supplied with the cartridge. Pleatco lists the application as the Sundance J-300 series. Replaces Jacuzzi OEM 6541-383.

Frequently Asked Questions
What filter replaces the Jacuzzi 6541-383?
The PJW60TL-OT-F2S replaces it directly, and so does every cross-reference for it: 6CH-961, FC-2715. All of them are the same 60 sq ft cartridge at 6.75" outer diameter and 15.5" long. Buy whichever is cheapest at the time with solid recent reviews.
Is the Jacuzzi 6541-383 the same as the PJW60TL-OT-F2S?
Yes, physically the same filter. Jacuzzi 6541-383 is an OEM number, meaning it is the code Jacuzzi put on the cartridge that shipped with the equipment. Jacuzzi does not manufacture cartridges. Pleatco, Unicel, and Filbur do, and they sell the identical part under their own numbers at a lower price. Match the dimensions against your old cartridge before ordering and you are covered.
Do I have to buy the Jacuzzi version?
No. Nothing about the housing requires an OEM-branded cartridge, and the warranty on your equipment is not voided by using an aftermarket filter that meets the same spec. The reason to buy OEM is convenience, not performance. The reason not to is price, which is often a meaningful gap for an identical part. What matters is that outer diameter, length, and end-cap style all match.
What size is the Jacuzzi 6541-383?
6.75 inches in outer diameter, 15.5 inches long, with 60 square feet of filter media. Both measurements need to land within about an eighth of an inch, and the end caps have to match so the cartridge seats correctly when you close the lid. Measure your old one rather than trusting a number that has worn off the label.
