Package and mounting — the TO-99 metal can
The TO-99-8 metal can is a through-hole package with eight leads on a circular footprint. It's a hermetic enclosure — the metal lid and glass-to-metal seals keep moisture and contaminants out.

Yes, the operating temperature range is -55°C to 125°C, so 125°C is within the rated limits. This is the military-grade temperature range, suitable for avionics and downhole environments.

The TLV9351IDCKR is a surface-mount, rail-to-rail, 3.5 MHz op-amp from TI, but it is not a pin-to-pin replacement — the TO-99-8 footprint and through-hole mounting are different. For a functional equivalent in the same package class, look for another TO-99-8 general-purpose op-amp with similar GBW and supply range.
The TO-99-8 metal can has eight leads arranged in a circular pattern. Standard op-amp pinout applies: offset null, inverting input, non-inverting input, V-, output, V+, and offset null. Refer to the TI datasheet for the exact pin numbering relative to the tab.
