同年齢 explicitly spells out 'age' with 齢 and sounds slightly more technical than 同年, though both mean 'the same age'.

同どう年ねん代だい
同年代 means 'roughly the same generation/age bracket', a looser grouping than 同年, which means exactly the same age or year.
同どう月げつ
同年 refers to the same year, while 同月 refers to the same month, so they are not interchangeable despite the similar 同〜 pattern.

Compound of 同 (どう, 'same') and 年 (ねん, 'year'). The 'same age' sense is a natural extension of 'same year (of birth)'.
