No stock-holding claim; sourced per BOM quantity.
The 0.100" pitch and single-row layout are standard across the MTA-100 family — the mating half must be a 7-position, single-row receptacle with a friction-lock ramp.
No official pin-compatible replacement is recorded from TE Connectivity. The MTA-100 series includes active headers with similar pitch and position count, but a board spin may be required to match the footprint and locking feature. Confirm the BOM position count and mating half before committing.
A shrouded header (like 644488-7) has a four-wall plastic enclosure around the pins that protects the contacts during mating and provides keying to prevent mis-mating.
