Key Features
- 4 positions in dual-row layout on compact 0.050" (1.27 mm) pitch for high-density SMT board interconnect
- Gold flash (3 µin) over Nickel (50 µin) mating contact finish for reliable low-resistance signal connections
- Phosphor bronze contact material providing excellent spring retention and consistent mating force
- Tin (Sn) over nickel barrier termination finish compatible with standard lead-free reflow soldering
- Compact body of 0.157" length x 0.155" breadth for ultra-space-constrained PCB placements
Applications
The TMM-102-05-F-D-SM is ideal for compact board-to-board signal interfaces in wearable electronics, handheld test instruments, and miniaturized industrial sensor modules where a 4-position dual-row connector must fit within a very small PCB footprint. Its 0.050 inch pitch allows twice the contact density of 0.100 inch pitch connectors in the same board area. The surface-mount termination style enables automated reflow assembly compatible with standard SMT production lines.

Frequently Asked Questions
Why use TMM-102-05-F-D-SM at 0.050 inch pitch instead of a standard 0.100 inch pitch connector for compact PCB designs?
The TMM-102-05-F-D-SM uses 0.050 inch (1.27 mm) pitch, delivering 4 dual-row contacts in a body only 0.157 inch long — half the board space of an equivalent 0.100 inch pitch connector. This allows designers to place signal interfaces in areas of the PCB that cannot accommodate larger connectors.
What contact material and plating does TMM-102-05-F-D-SM use, and how does it affect signal integrity in high-cycle applications?
TMM-102-05-F-D-SM uses phosphor bronze contacts with gold flash (3 µin) over nickel (50 µin) on the mating surfaces. Phosphor bronze provides excellent spring retention over many mating cycles, while the gold flash finish keeps contact resistance low and prevents oxidation, suitable for applications with up to a few dozen mate-unmate cycles.
Is TMM-102-05-F-D-SM compatible with lead-free reflow soldering, and what termination finish does it have?
Yes, TMM-102-05-F-D-SM uses tin (Sn) with a nickel (Ni) barrier on its SMT termination contacts, which is fully compatible with standard lead-free reflow soldering profiles up to 260°C peak temperature. This makes the connector suitable for RoHS compliant manufacturing without special handling requirements.
For a miniaturized wearable design, what are the body dimensions of TMM-102-05-F-D-SM and how does it compare to larger SMT connector options?
TMM-102-05-F-D-SM measures 0.157 inch (3.99 mm) body length by 0.155 inch (3.94 mm) breadth by 0.109 inch (2.77 mm) depth, making it one of the most compact 4-position dual-row SMT connectors available. Compared to standard 0.100 inch pitch 4-position connectors, this part occupies roughly 50% less PCB area per position.
