Frequently Asked Questions
What position count and pitch does the TSM-122-04-SM-DH-A-K-TR use for PCB interconnection?
The TSM-122-04-SM-DH-A-K-TR provides 44 positions in a dual-row layout with a 0.100 inch (2.54 mm) pitch, a broadly compatible standard pitch that aligns with common mating headers, prototyping breadboards, and 0.100 inch ribbon cable connectors used in industrial and commercial electronics.
Can TSM-122-04-SM-DH-A-K-TR be used in a production PCB requiring automated SMT assembly?
Yes, the TSM-122-04-SM-DH-A-K-TR is designed for surface-mount technology (SMT) assembly, making it fully compatible with automated pick-and-place machines and standard reflow soldering. The 2.54 mm pitch pads are suitable for standard solder paste stencil printing, simplifying integration into high-volume production lines without through-hole tooling.
How does the dual-row 44-position TSM-122-04-SM-DH-A-K-TR compare to a single-row 44-position alternative for a space-limited PCB?
A dual-row configuration at 2.54 mm pitch occupies approximately half the PCB length of a single-row 44-position connector. The TSM-122-04-SM-DH-A-K-TR dual-row body is roughly 27 mm long versus 55 mm for a single-row 44-position alternative, making it a preferable choice when PCB edge length is limited but a full 44-signal interface is required.
What mating header series is recommended for use with the TSM-122-04-SM-DH-A-K-TR in a board-to-board stack?
SAMTEC recommends pairing the TSM-122-04-SM-DH-A-K-TR with mating headers from the TSW or TFW series at 2.54 mm pitch, which provide matching 44-position dual-row mating contact geometry. The inter-board stack height is determined by the selected header's pin post length, typically ranging from 6 mm to 25 mm depending on the specific variant chosen.
