What the G7L-1A-TUB DC24 actually is
The Omron G7L-1A-TUB DC24 is a member of the G7L series of general-purpose relays, ordered under part number G7L-1A-TUB DC24 with a DC24-rated coil — the -TUB suffix in the G7L family marks the PCB-terminal mounting style used when the relay is soldered directly to a board rather than socketed.
Why lifecycle reads 'mature' for this G7L line
Lifecycle stage is recorded as mature for the G7L-1A-TUB DC24, which in Omron's parts vocabulary means the series is no longer in the newest-product window but remains a current catalog item — existing designs continue to be supported and new orders are still accepted, while the datasheet is no longer being actively revised with new derivatives.
