Frequently Asked Questions
Why choose a 2.00 mm pitch like QTT-117-01-G-T over 2.54 mm pitch connectors for power plane board-stacking?
The 2.00 mm pitch of QTT-117-01-G-T provides approximately 21% higher pin density compared to 2.54 mm pitch alternatives, fitting 51 power and ground contacts in a body length of 1.353 inches. This compact layout is advantageous for high-current power plane distribution in server and telecom equipment where board space is limited but a large number of parallel power contacts are needed.
What current rating can be expected per contact in QTT-117-01-G-T for power distribution applications?
Phosphor bronze contacts with gold (20 µin) plating in QTT-117-01-G-T typically support current ratings of 1 A to 3 A per pin depending on contact size and ambient temperature, following Samtec power connector design guidelines. Paralleling multiple pins in the 51-position strip allows aggregate current capacity suitable for 12 V or 5 V power plane distribution in multi-board stacking architectures.
Is QTT-117-01-G-T RoHS compliant, and does its gold plating meet international procurement standards?
Yes, QTT-117-01-G-T carries a Pbfree code indicating RoHS compliance, confirming the connector is free of restricted hazardous substances under EU RoHS 2 and similar regulations. The 20 µin gold mating finish over nickel barrier meets MIL-DTL-83733 and ASTM B488 gold plating standards commonly required for defense and industrial procurement specifications.
How does QTT-117-01-G-T fit into a multi-board stacking architecture with strict height constraints?
QTT-117-01-G-T has a body breadth of 0.236 inch and body depth of 0.276 inch, with the mating stack height determined by the matched Samtec receptacle and board spacing. For constrained vertical stacking heights — typically 4 mm to 20 mm between boards — the 51-position, 2.00 mm pitch terminal strip enables power plane routing within a narrow inter-board gap, critical in blade server and compact embedded computing designs.
