SL 11 139 19 G

Headers, Male Pins Overview

The SL 11 139 19 G is a single-row male pin header connector manufactured by Fischer Elektronik. It features a 0.635 mm (0.025 inch) contact pitch and accommodates 19 positions. The component utilizes through-hole termination for PCB mounting. Contact surfaces are tin-plated with a thickness of 157.5 µin (4.00 µm). The mating contact length measures 0.319 inches (8.10 mm), while the column contact length is 0.118 inches (3.00 mm). Total contact length is 0.547 inches (13.90 mm). Insulation height is 0.110 inches (2.80 mm). The housing material is polyamide (PA46), and contacts are made of copper-tin alloy.

Headers, Male Pins Feature Summary

• Precision-engineered one-row configuration designed for reliable signal transmission
• Square-shaped contact geometry ensures stable mechanical engagement
• Tin-plated contact surfaces provide corrosion resistance and conductivity

Headers, Male Pins Applications

• General-purpose board-to-board interconnections
• Prototype development and testing setups
• Industrial control panel wiring

Headers, Male Pins Procurement Notes

Verify that the ordering suffix 'G' corresponds to the specific tin plating requirement as defined in the official Fischer Elektronik datasheet. Confirm that the 19-position count matches the design layout. Ensure compatibility with standard 0.635 mm pitch sockets or cables. Check RoHS compliance status if required by project specifications. Cross-reference the part number with the manufacturer's current catalog to confirm availability and production status.

Headers, Male Pins Selection Notes

Select this component when a single-row, 0.635 mm pitch male header is required for through-hole assembly. The 19-position count suits applications needing moderate channel density without occupying excessive board width. The tin-plated contacts offer a cost-effective solution for non-high-frequency signals. Consider insulation height and total contact length for enclosure clearance. This series is suitable for general electronic equipment where high-density multi-row connectors are not necessary.

Headers, Male Pins Part Context

The SL 11 139 series represents Fischer Elektronik's standard line of precision male pin headers. These components are characterized by their small 0.635 mm pitch, allowing for compact circuit board designs. The series offers various position counts to accommodate different connectivity needs. The SL 11 139 19 G specifically denotes the 19-position variant within this family, maintaining consistent dimensional and electrical characteristics across the range.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, 19 positions, single-row male format, and through-hole mounting style. Verify identical contact material and plating thickness for equivalent performance. Fischer Elektronik part numbers such as SL 11 139 16 G or SL 11 139 21 G may serve as adjacent options if position count flexibility exists.
