1 Chronicles 3:16 - Ellicott's Commentary On The Whole Bible

Jeconiah (Iah establish!)= Jehoiachin (Iahweh establisheth) = Coniah (Jeremiah 22:24; Jeremiah 22:28 — an abbreviation of Jeconiah), was carried captive to Babylon by Nebuchadnezzar (2 Kings 24:15), and Zedekiah his father’s brother, became king in his stead. Hence the supposition that “Zedekiah his son” means “Zedekiah his successor” on the throne. (Comp. margin.) But (1) the phrase “his son” has its natural sense throughout the preceding list; and (2) there really is nothing against the apparent statement of the text that Jeconiah the king had a son named Zedekiah, after his great-uncle. As, like Johanan (1 Chronicles 3:15), he did not come to the throne, this younger Zedekiah is not mentioned elsewhere. (See 1 Chronicles 3:17, Note.)
