Lifecycle reality — obsolete with no official replacement
The TE 5-1634556-0 is listed as obsolete. No official successor order code is on record. The ZDC/Greenpar series is a legacy line, so if you are maintaining an existing build, confirm the mating half and panel cut-out match before committing to a broker buy.
The 50 Ohm impedance and 4 GHz maximum frequency define the usable bandwidth — this jack will pass signals cleanly up to 4 GHz before the return loss degrades. The 500 V rating is the dielectric withstand between centre contact and shield, governed by the polymethylpentene (PMP) insulator; it is not a continuous operating voltage but a peak rating for the air gap and creepage path. The gold centre contact plating supports the 500-cycle mating life without fretting corrosion — important if this jack lives on a panel that gets re-patched regularly.
