TST-112-04-T-D-RA

Headers, Male Pins Overview

The TST-112-04-T-D-RA is a .100" (2.54mm) pitch Shrouded Terminal Strip header manufactured by Samtec Inc. This component features a double row configuration with 12 positions, designed for board-to-cable or wire connections. It utilizes a right-angle through-hole termination style and includes a four-wall shroud to ensure proper alignment during mating. The connector employs a push-pull fastening mechanism and is constructed with matte tin over nickel contact plating on phosphor bronze terminals. The insulating material is polybutylene terephthalate (PBT) reinforced with glass fiber, rated UL94 V-0, supporting an operating temperature range of -55°C to 105°C.

Headers, Male Pins Feature Summary

• Four-wall shrouded design ensures precise alignment and prevents pin damage during insertion.
• Push-pull fastening system provides secure mechanical retention without requiring screws.
• Right-angle through-hole termination facilitates compact board layout and cable routing.
• Matte tin over nickel plating offers reliable conductivity and corrosion resistance.

Headers, Male Pins Applications

• Board-to-cable interconnections in industrial control systems

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against the official Samtec datasheet to confirm exact pin count, orientation, and termination type. Ensure that the matte tin plating specification meets the environmental requirements for the intended application. Confirm compatibility with mating socket strips from the same Flex Stack TST series to guarantee correct interface dimensions and electrical performance.

Headers, Male Pins Selection Notes

Select this component when a low-cost, high-reliability terminal strip is required for .100" pitch applications. The right-angle form factor is suitable for space-constrained designs where cables need to exit perpendicular to the board. Consider the current rating and temperature derating characteristics if high-power signals are involved. Verify that the shrouded height accommodates the mating connector's guide pins.

Headers, Male Pins Part Context

This part belongs to the Samtec Flex Stack TST series, which provides versatile terminal strip solutions for various interconnect needs. The TST series is known for its cost-effective design and robust mechanical performance. Components in this family share common mounting footprints and mating interfaces, allowing for modular design approaches across different product lines.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other .100" pitch shrouded headers with matching 12-position double-row configurations. Ensure any replacement maintains the same right-angle through-hole termination and push-pull fastening mechanism. Verify that the mating socket strip has compatible guide pin spacing and shroud dimensions to prevent assembly issues.
