Frequently Asked Questions
What pitch and row configuration does the ERF8-040-01-L-D-RA-TR use?
The ERF8-040-01-L-D-RA-TR uses a 2.54 mm pitch dual-row configuration with 80 total positions (40 per row), making it suitable for high-density board stacking interconnects where space efficiency and signal count are critical.
How does the right-angle tail orientation affect PCB layout for this SAMTEC connector?
The right-angle (RA) tail exits the connector body perpendicular to the mating axis, allowing the connector to mate vertically while the PCB lies flat. With a body length of 1.772 inches and depth of 0.447 inches, designers must allocate adequate clearance along the board edge in stacking or backplane layouts.
Is ERF8-040-01-L-D-RA-TR RoHS compliant and what is the contact finish?
Yes, the ERF8-040-01-L-D-RA-TR carries a Pb-free (RoHS) rating. Its contacts use a Tin (Sn) finish over a Nickel (Ni) barrier layer, which provides good solderability and corrosion resistance across the connector's rated operating temperature range.
What is the typical lead time and availability for ERF8-040-01-L-D-RA-TR?
SAMTEC lists a 1-week factory lead time for the ERF8-040-01-L-D-RA-TR. It is a standard catalog part with 80 positions and worldwide distribution, making it readily accessible through authorized distributors for both prototype quantities and production volumes.
