Key Features
- 2-position single-row low-profile female socket with 0.100" pitch enabling compact, minimal-footprint PCB signal connections with broad pin header compatibility
- 30 µin gold over 50 µin nickel mating contact finish provides superior corrosion resistance and supports 500 or more reliable mating cycles
- RoHS-compliant lead-free construction with Pb-free termination supports environmentally responsible global manufacturing and regulatory compliance
- Low-profile body (0.1" breadth, 0.209" length) minimizes connector height and board footprint for space-constrained PCB designs
Applications
The SL-102-G-19 is used in compact PCB interconnect designs requiring 2-position female socket connectivity at the standard 0.100" pitch, such as sensor interface boards, LED driver modules, power distribution headers, and MCU peripheral connectors. Its low-profile form factor and gold-plated contacts make it well suited for space-constrained consumer electronics, wearable device PCBs, and precision measurement instruments where connector height must remain below 4 mm. This socket also serves as a field-replaceable jumper and configuration header in industrial PLCs, embedded computing modules, and RF calibration boards requiring reliable low-resistance connections.

Frequently Asked Questions
What contact finish does SL-102-G-19 use and how many mating cycles does it support?
The SL-102-G-19 uses 30 µin gold over 50 µin nickel on the mating contacts, a premium finish that provides excellent corrosion resistance and low contact resistance below 20 mΩ. The 30 µin gold thickness supports 500 or more reliable mating cycles, making it suitable for applications with frequent connector disconnection such as test fixtures, configuration jumpers, and field-serviceable module interfaces.
How does the low-profile design of SL-102-G-19 benefit height-constrained PCB assemblies?
The SL-102-G-19 body measures only 0.1" in breadth and 0.209" in length, keeping the connector height well within low-profile PCB height envelopes under 5 mm. This compact form factor is critical for stacked PCB assemblies, enclosures with clearances under 8 mm, and wearable electronics where connector height above the board surface must be minimized to less than 4 mm to fit within device enclosures.
In which sensor and power interface applications is SL-102-G-19 commonly used?
The SL-102-G-19 is commonly used as a 2-pin female socket for sensor power and signal headers on temperature, pressure, and humidity sensor modules supplying 3.3 V or 5 V to attached sensing elements. It also serves as a power connector on LED driver boards carrying up to 1 A per contact, jumper socket headers for PCB configuration selection, and 2-wire serial interface (I2C or UART at 115200 baud) connectors on embedded microcontroller development boards.
How does SL-102-G-19 source availability and lead time compare to other 2-position socket options?
The SL-102-G-19 has a factory lead time of approximately 1 week from SAMTEC, which is notably shorter than many specialty connector lead times of 8 to 16 weeks. Its RoHS-compliant status and standard 0.100" pitch make it widely stocked by global distributors, typically with immediate availability from distributor warehouse inventory for orders under 500 pieces. This short lead time and broad availability make it a reliable drop-in socket choice for both prototype and production PCB designs.
