SL 11 139 35 S

Headers, Male Pins Overview

The Fischer Elektronik SL 11 139 35 S is a single-row male header connector designed for through-hole mounting. It features 35 positions with a contact pitch of 0.100 inches (2.54 mm). The contacts are constructed from copper-tin alloy and feature tin plating on both the mating and post sections, with a specific thickness of 157.5 µin (4.00 µm) for the mating surface. The connector utilizes polyamide (PA46) insulation, classified under UL 94 V-0 flammability standards. Key dimensional specifications include an overall contact length of 0.547 inches (13.90 mm), a mating contact length of 0.319 inches (8.10 mm), and a post contact length of 0.118 inches (3.00 mm).

Headers, Male Pins Feature Summary

• Single-row configuration with square-shaped male pins for reliable board-to-board or cable connections.
• Through-hole termination method ensuring secure mechanical attachment to printed circuit boards.
• Tin-plated copper-tin contacts providing corrosion resistance and stable electrical conductivity.
• Polyamide (PA46) insulation material offering high thermal stability and UL 94 V-0 flame retardancy.

Headers, Male Pins Applications

• General electronic equipment interconnections requiring standard 2.54 mm spacing.
• Industrial control systems utilizing Fischer Elektronik SL series components.
• Prototyping and development boards needing robust male pin headers.
• Consumer electronics assemblies with through-hole design constraints.

Headers, Male Pins Procurement Notes

Verify the exact suffix 'S' against the manufacturer's current datasheet to confirm plating specifications and material composition. Ensure the ordering part number matches the required pin count of 35. Confirm that the through-hole package style aligns with your PCB fabrication capabilities. Cross-reference the UL 94 V-0 rating if fire safety compliance is critical for the end application. Validate the operating temperature range against system requirements before finalizing procurement.

Headers, Male Pins Selection Notes

Select this component when a single-row male header with 35 positions is required. The 2.54 mm pitch is standard for general-purpose electronics. Consider the tin plating for cost-effective connectivity without gold plating costs. The PA46 insulation supports higher thermal loads compared to standard nylon. Ensure the 3.00 mm post length fits within the available board clearance. Verify compatibility with mating female sockets or cables designed for 0.100 inch spacing.

Headers, Male Pins Part Context

The SL 11 139 series represents Fischer Elektronik's precision-engineered male connectors. This series emphasizes reliability in demanding environments through robust material selection. The 139 designation typically refers to specific dimensional profiles within the product line. Components in this family are designed for consistent performance across various industrial applications. The series offers multiple position options to suit diverse circuit density requirements.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other Fischer Elektronik headers within the SL 11 139 series with different pin counts, such as SL 11 139 36 Z or SL 11 139 7 Z, provided the pitch and row configuration match. Generic equivalents must maintain the 2.54 mm pitch, through-hole termination, and similar contact materials. Verify that any replacement meets the same UL 94 V-0 insulation rating and thermal endurance specifications.
