Resin and reclaim may share some similarities, but they are very different end products. Both have cannabinoids, terpenes and lipids that were not fully vaporized or combusted when the initial cannabis product was smoked.
However, unlike reclaim, resin also is made up of burnt plant material and tar. Additionally, pipe resin contains minimal cannabinoid content, while concentrate reclaim can contain anywhere from about 20%-60% THC. Both will have very low levels of terpenes, but reclaim is likely to have more than resin.
