70-Position Dual-Row Layout for Dense Board Wiring
The 1-535512-0: This is a 70-position, dual-row receptacle from the AMPMODU Mod II series, with a mating pitch of 0.100" (2.54 mm) and a matching row-to-row spacing of 0.100" (2.54 mm). The 70 circuits are fully loaded, so every position is available for signal routing. The solder posts measure 0.115" (2.92 mm) long, typical for a standard PCB thickness. Each contact is rated 2 A, and the mating surface carries 30.0 µinch (0.76 µm) gold over the phosphor bronze base.
The 0.100" pitch sets the per-row hole pattern at 2.54 mm centers, a standard grid that routes easily on a two-layer board. The dual-row footprint spans 69.85 mm across the 70 positions, and the row spacing adds another 2.54 mm of keep-out width. The insulation height of 0.238" (6.05 mm) above the board is the clearance needed under the mated header. The right-angle solder tails exit the housing parallel to the board, so the connector body sits flush against the edge. This orientation is common for mezzanine or daughtercard connections where the cable or header approaches from the side, not from above.
The base product number is 535512, which covers the series of right-angle receptacles with this contact finish and post length. The tube packaging is standard for through-hole connectors that feed into selective-solder or hand-load assembly.
Environmental and Compliance Ratings
The post-side contact finish is tin-lead at 50.0 µinch (1.27 µm), which is a standard solderable finish for through-hole wave-solder processes. The mating side is gold, so the contact interface is corrosion-resistant even if the connector is unmated for long periods.
