1500440

Overview

Phoenix Contact part number 1500440 is a PCB connector belonging to the DD31PS series. It features an 18-position configuration with female sockets arranged in a single row. The component utilizes a push-in spring connection method for wire termination and is designed for free-hanging, in-line mounting on printed circuit boards. The housing is constructed from black polybutylene terephthalate (PBT). Key electrical ratings include a nominal current of 8 A and a rated voltage of 160 V under category III/2 conditions. The contact surface is tin-plated, and the pitch between contacts is 3.81 mm.

Feature Summary

• Push-in spring connection technology enables tool-free wire termination without screwdriver assistance.
• Free-hanging in-line design allows flexible orientation and integration into various panel layouts.
• Tin-plated contact surfaces ensure reliable conductivity and corrosion resistance.

Applications

• Industrial control cabinet wiring
• Automation system signal distribution
• Printed circuit board interconnection modules

Procurement Notes

Verify the specific datasheet version before procurement to confirm compliance with current RoHS and REACH standards. Ensure that the required wire gauge matches the 1.5 mm² nominal cross-section specification. Confirm that the 3.81 mm pitch aligns with the target PCB footprint design to prevent mechanical mismatch during assembly.

Selection Notes

Select this component when a robust, tool-free termination method is required for industrial environments. The 18-position count suits moderate-density signal routing needs. Consider the 8 A current rating for power distribution applications within the specified voltage limits. Verify that the black PBT housing meets the thermal and chemical resistance requirements of the installation environment.

Part Context

This connector belongs to the DD31PS series of PCB headers from Phoenix Contact. The series is characterized by its compact form factor and reliable spring-clamp technology. It is commonly used in modular terminal block systems where quick assembly and maintenance are prioritized over traditional screw connections.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific 18-position variant. Alternative solutions may require redesigning the PCB footprint due to differences in pin counts or pitch dimensions.
