Key Features
- 20-pin board stacking connector with 0.5 mm pitch enables ultra-compact board-to-board interconnects in space-constrained portable devices
- 3.0 mm stacking height provides precise inter-board spacing for tight PCB stack assemblies in wearables, cameras, and IoT modules
- Gold-plated termination contacts (JESD-609 e4 rated) ensure reliable low-resistance mating over thousands of insertion cycles
Applications
The DF12B(3.0)-20DP-0.5V(86) is designed for compact board-to-board stacking in smartphones, tablets, wearable devices, and IoT sensor modules where a 20-pin, 0.5 mm pitch connector at a fixed 3.0 mm stack height is needed to relay power and data between main and sub-boards. Its gold-plated contacts and RoHS compliance also make it suitable for medical diagnostic instruments and industrial handheld terminals requiring long-term contact reliability.

Frequently Asked Questions
What stacking height and pitch does the DF12B(3.0)-20DP-0.5V(86) offer, and how does that shape PCB layout?
This Hirose connector provides a fixed 3.0 mm stacking height at 0.5 mm pitch across 20 positions. PCB designers must reserve a 3.0 mm vertical clearance between the two boards and lay out pads on a 0.5 mm grid, which requires careful impedance planning on adjacent signal layers to avoid crosstalk in high-speed designs.
How does the gold-plated termination contact finish on the DF12B(3.0)-20DP-0.5V(86) affect long-term reliability?
Gold plating (Au) on the termination contacts significantly reduces oxidation-related contact resistance degradation over thousands of mating cycles. In field-replaceable sub-module designs where the board stack may be separated and reconnected tens to hundreds of times, the gold finish maintains contact resistance well below 50 mΩ per pin across typical lifecycle durations.
Is DF12B(3.0)-20DP-0.5V(86) a suitable drop-in alternative for other 20-pin 0.5 mm pitch Hirose DF12 series connectors with different stacking heights?
No; the DF12 series designates stacking height in the part number — the '3.0' specifies 3.0 mm. Variants with 2.0 mm, 2.5 mm, or 4.0 mm stacking heights use different housings and are not mechanically interchangeable even though they share the same 0.5 mm pitch and 20-pin count, because the male plug length changes with stacking height.
