Board Fit and Signal Density
The 90309-010LF: For a signal-level interconnect (GPIO, I2C, SPI, low-power sensor lines), this is ample headroom.
Contact Finish and Mating Durability
The mating surface carries Gold GXT™ at 8.00 µinch (0.203 µm) over copper alloy — a moderate gold thickness that supports a few hundred mating cycles.
Shrouding and Polarization
The keying slot prevents reverse insertion, which saves a board spin if the mating half is keyed. Push-pull fastening means no tools needed for mating or unmating — but it is not a locking latch.
Housing is UL94 V-0 rated — the standard flame class for connectors inside power supplies, industrial controllers, and telecom equipment where the enclosure limits oxygen and the connector must not propagate flame. RoHS compliant per entry — no restricted substances in the plating or thermoplastic.
No official pin-compatible alternative is listed from the manufacturer. If a second source is needed, the Minitek® series includes other 2.00 mm pitch headers with the same footprint — verify the position count and keying before substituting.
