Selection questions
Do the overlaid ratings establish the actual version?
No. The UF5H5-503 reference and numeric dimensions remain merchant information. Confirm the complete supplied label, measured depth and connection before ordering.
Which supplied-unit details are still needed?
Obtain the complete manufacturer label, ordering option, actual outline and connector pin assignment. Retained manufacturer/model text is a merchant reference, not independent stock verification.
Other retained electrical, dimensional and application fields remain merchant records. Exact-version technical specifications, actual condition, package contents and equipment compatibility require confirmation.
