Key Features
- 60-position dual-row board-stacking receptacle on 0.8 mm pitch with ELP contacts for high-density, low-profile board-to-board interconnect
- Integrated polarization feature and positioning pins ensure correct, repeatable PCB alignment and prevent mis-insertion during assembly
- RoHS-compliant construction with gold-plated contacts supports reliable signal integrity in industrial, telecom, and computing stack applications
Applications
The QTH-030-03-F-D-A is designed for high-density mezzanine and board-stacking assemblies in telecommunications line cards, computing backplane systems, and industrial embedded modules where 60 signals must be routed between stacked PCBs with precise alignment. Its ELP contacts and positioning pins allow secure, repeatable mating in automated assembly environments, reducing field failures in mission-critical stacked-board architectures.

Frequently Asked Questions
How many positions and what pitch does the SAMTEC QTH-030-03-F-D-A board-stacking connector provide?
The QTH-030-03-F-D-A provides 60 positions across 2 rows (30 per row) on a 0.8 mm pitch. This high-density layout allows 60 signals to pass between stacked PCBs within a footprint measuring approximately 0.789 inch in length, making it compact enough for mezzanine and line-card designs.
What role do the ELP contacts and positioning pins play in the QTH-030-03-F-D-A assembly?
ELP (extended-length pin) contacts provide a longer wipe length during mating, improving contact reliability under vibration, while the integrated positioning pins register the connector body to specific PCB holes for repeatable alignment within ±0.1 mm. Together they reduce mis-mating and signal-integrity issues in dense 60-position board-stacking applications.
Which board-stacking architectures benefit from substituting the QTH-030-03-F-D-A for a lower-density alternative?
Telecom line cards, FPGA daughter-card modules, and industrial embedded computing stacks that need to route 60 signals at 0.8 mm pitch benefit most. At this pitch, a single QTH-030-03-F-D-A replaces two 30-position connectors, cutting solder joints by 50% and reducing PCB real estate consumed by board-stacking interconnects in space-constrained chassis.
