Hello,
Thank you for your question. The Suburban 5143A and 5243A are the same SW10DE 10-gallon gas/electric water heater with the same specifications, dimensions, and performance.
The primary difference is the manufacturer's packaging:
- 5143A is typically supplied in plain packaging.
- 5243A is typically supplied in updated retail packaging.
Functionally, there is no difference between the two units—they install and operate the same way. If you're deciding between them, you can choose based on availability and price with confidence that you'll be receiving the same water heater.
Please let us know if you have any other questions—we're happy to help!
