Key Features
- 6-position single-row vertical header at 0.050" (1.27 mm) pitch in a low-profile 0.237" body for space-constrained PCB designs
- Gold (10 µin) mating and gold termination contacts over nickel barrier ensure low contact resistance and long-term reliability
- RoHS compliant Pb-free construction supports lead-free soldering and green electronics initiatives
- 1-week factory lead time provides fast procurement flexibility for prototype and low-volume production builds
Applications
The TMM-103-02-G-S is suited for compact board-to-board and board-to-wire interconnect applications in embedded systems, sensor modules, and portable instruments where a 6-position single-row interface at 0.050" pitch must occupy minimal vertical clearance. Its gold-over-nickel contact system ensures reliable low-resistance connections in vibration-prone or harsh environments. The low-profile vertical header design supports tight PCB stack-ups in multi-board enclosures.

Frequently Asked Questions
What are the key mechanical dimensions and pitch of the TMM-103-02-G-S header?
The TMM-103-02-G-S features a 0.050" (1.27 mm) pitch with a body length of 0.237", breadth of 0.079", and depth of 0.059", providing a 6-position single-row vertical interface in a low-profile footprint for space-constrained PCB applications.
What contact finish does the TMM-103-02-G-S use, and why does it matter for signal reliability?
Both the mating and termination contacts are finished with gold over a nickel barrier (10 µin gold), delivering contact resistance below 10 mΩ, excellent corrosion resistance, and suitability for high-cycle interconnects in industrial and instrumentation applications.
In which compact embedded system applications is the TMM-103-02-G-S most appropriate?
The 6-position single-row 0.050" pitch layout makes the TMM-103-02-G-S appropriate for sensor breakout boards, SPI or I2C peripheral modules, and low-power embedded modules where a minimal 6-pin header must fit within a 0.237" footprint and 0.079" board spacing.
What lead time and availability considerations apply when sourcing the TMM-103-02-G-S for production?
The TMM-103-02-G-S carries a 1-week factory lead time from SAMTEC, making it accessible for short-run prototype builds and low-volume production; distributors frequently stock the part, reducing effective lead time to same-day or next-day delivery for standard order quantities.
