Obsolete — sourcing and replacement options
The 146135-4: No direct replacement is documented in the evidence, but the AMPMODU Mod II series includes many active 0.100" pitch breakaway headers with similar footprints — a pin-compatible alternative would require matching the 10-position, dual-row, surface-mount, unshrouded configuration and tin-lead or gold plating.
This header mates with standard AMPMODU Mod II receptacles and IDC connectors that accept 0.025" square pins on 0.100" pitch. Termination is solder, surface-mount style. The unshrouded design exposes the pins for easy probing and rework, but offers no polarization — verify keying alignment during assembly.
