Applications
The TMM-103-03-G-D is designed for compact PCB-to-PCB and wire-to-board connections in low-profile embedded systems, small industrial sensors, and handheld electronic devices where a 6-position dual-row connector must fit within a body length of 0.237" and body depth of 0.059". It is well-suited for routing power and control signals on miniaturized modules used in medical equipment, robotics, and IoT edge devices. Its gold-plated contacts ensure reliable performance in environments subject to vibration or intermittent mechanical stress.

Frequently Asked Questions
What are the key physical dimensions of the TMM-103-03-G-D and why do they matter for compact designs?
The TMM-103-03-G-D has a body length of 0.237", body breadth of 0.155", and body depth of only 0.059". These compact dimensions allow it to fit in PCB areas too small for standard 0.100" pitch connectors, making it ideal for miniaturized IoT sensor nodes, medical implantables, and handheld instruments where the connector must occupy under 40 mm² of board space.
What contact finish does the TMM-103-03-G-D use, and how does that affect connector longevity?
The TMM-103-03-G-D features a gold (20 µin) over nickel (50 µin) finish on both the mating and termination surfaces. Gold plating prevents oxide buildup and maintains contact resistance below 30 mΩ even after hundreds of mating cycles, making the connector reliable in applications subject to repeated disconnection such as field-serviceable sensor modules or test fixtures.
How quickly can the TMM-103-03-G-D be sourced, and is it RoHS compliant?
SAMTEC lists a factory lead time of 1 week for the TMM-103-03-G-D, making it suitable for rapid prototyping and short-run production. The connector carries a RoHS compliant designation, meaning it meets EU Directive 2011/65/EU restrictions on hazardous substances including lead, cadmium, and mercury — a requirement for products sold in EU markets and most global OEM supply chains.
For a 6-pin dual-row connector, when is the TMM-103-03-G-D preferable to a single-row 6-pin header?
The dual-row TMM-103-03-G-D is preferable when PCB trace routing must be split across 2 separate rows to reduce board length, or when the design requires 2 independent ground returns to minimize ground bounce on signal-dense buses. With a 6-position dual-row layout (3 contacts per row), it routes 6 signals in a body length of 0.237" — roughly half the length of a single-row 6-pin header at equivalent pitch.
