TST-105-04-G-D-LA

Headers, Male Pins Overview

The TST-105-04-G-D-LA is a shrouded PCB header from Samtec's Flex Stack, TST series. It features a 2.54 mm (0.100 inch) pitch with 10 positions arranged in two rows. Designed for right-angle through-hole mounting, it utilizes gold-plated phosphor bronze contacts and a black PBT insulator rated UL94 V-0. The connector supports a mating column length of 6.35 mm and includes a four-wall shield with keying features. Operating temperature ranges from -55°C to +125°C, with a current rating of 3.4 A per contact.

Headers, Male Pins Feature Summary

• Right-angle board-to-board or wire-to-board interconnect design
• Four-wall shrouded housing provides mechanical alignment and protection
• Gold-plated contacts ensure reliable signal transmission
• Keyed configuration prevents incorrect mating

Headers, Male Pins Applications

• High-density electronic assemblies requiring vertical clearance
• Board-to-board connections in compact industrial equipment
• Wire-to-board interfaces in consumer electronics
• Automotive control modules with space constraints

Headers, Male Pins Procurement Notes

Verify the specific suffix 'LA' against the manufacturer datasheet to confirm lead angle and packaging details. Ensure the required mating height aligns with the 6.35 mm specification. Confirm RoHS3 compliance requirements for the target market. Check for moisture sensitivity level (MSL) handling instructions if storage duration exceeds limits. Validate that the right-angle orientation matches the PCB layout constraints.

Headers, Male Pins Selection Notes

Select this component when a right-angle connection is necessary to save vertical space. The shrouded design is preferred for automated assembly to guide pins accurately. The 2.54 mm pitch ensures compatibility with standard mating connectors. Consider the 3.4 A current rating for power distribution needs. Verify that the PCB thickness accommodates the through-hole soldering process without warping.

Headers, Male Pins Part Context

This part belongs to the Flex Stack family, known for high-reliability interconnects. The TST series specifically offers shrouded headers for precise alignment. The 'G' indicates gold plating, while 'D' denotes dual rows. The 'LA' suffix typically specifies the right-angle configuration and lead style. This series is widely used in applications demanding robust mechanical stability and consistent electrical performance.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Samtec TST series parts with matching pitch and position count. Verify that alternative models maintain the same right-angle orientation and shrouded design. Cross-reference contact material and plating thickness to ensure equivalent conductivity. Ensure the replacement part shares the same UL94 V-0 flammability rating and operating temperature range.
