It's all a case of reading the datasheet.
The TLE2426CLPR is still a LP case (i.e. through hole) with the only difference to the CLPE3 is the quanitity they come supplied in from the manufacturer.
The JG, and P packages are both through hole. The only SMD option is D, as you really don't want to be going for the chip form Y.
So you need a TLE2426CD of some variation, or swap the C for an I or M if you wanted extended temp range.

As for the pin layout/size, all the package drawings are at the end of the datasheet.

If you search for TLE2426CD mouser comes up with various options, including the extended temp range ones, so just compare the part number with the order numbers near the end of the datasheet to see what the differences are.
