The through-hole solder tails and push-pull fastening keep the assembly straightforward — no locking hardware, no shrouding to block access during rework.
The 87052 base number covers dual-row, unshrouded through-hole headers at 0.100" pitch. The 87052-120HLF loads all 20 positions. For a BOM that specifies gold-plated mating for cycle life, the HLF is the correct call; the RLF is a cost-down option for one-time or low-cycle assembly.
Both share the same 20-position dual-row footprint and 0.100" pitch. The HLF variant uses gold or Gold, GXT™ plating on the mating surface; the RLF typically uses tin. For applications requiring repeated mating cycles, the HLF gold plating is the better choice.
Rated 5 A per circuit at 110 V — signal-level current, not for power bus duty.
