311-83-121-41-001101

Headers, Receptacles, Female Sockets Overview

The Preci-Dip 311-83-121-41-001101 is a board-to-board connector socket featuring 21 positions in a single row configuration. It utilizes a 0.100-inch (2.54mm) mating pitch and is designed for through-hole solder termination. The component incorporates female circular pin sockets with gold-plated contacts and a black insulator made of glass-filled polycyclohexylene terephthalate. Rated for 3A current, it operates within a temperature range of -55°C to 125°C and meets UL94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Feature Summary

• Push-pull locking mechanism secures the connection between mating boards.
• Gold-plated beryllium copper contacts ensure reliable signal transmission.
• Glass-filled polyester insulation provides structural stability and heat resistance.

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnections
• Backplane systems
• Industrial control modules

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific ordering suffix matches the required contact length and insulation height specifications. Confirm RoHS3 compliance status if environmental regulations apply to the assembly. Ensure the selected variant aligns with the intended PCB layout dimensions and thermal requirements for the target application environment.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a low-profile, single-row female header is required for direct board stacking. The push-pull feature simplifies assembly and disassembly processes compared to standard friction-fit connectors. Evaluate the 3A rating against the total load requirements of the circuit design to ensure adequate performance margins.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Preci-Dip 311 series of rectangular connectors. It serves as a female socket counterpart to male headers, facilitating secure electrical pathways in compact electronic assemblies. The design emphasizes durability and consistent contact performance across repeated mating cycles.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other Preci-Dip 311 series variants with matching 21-position counts and 0.100-inch pitch. Verify that alternative part numbers maintain identical push-pull locking mechanisms and compatible insulation heights for proper mechanical fit.
