1500433

Overview

The Phoenix Contact DD31PS 1,5/8-3,81-X (Part No. 1500433) is a PCB plug-in connector from the CONNEXIS Connectors S product line. It features an 8-position, 2-row configuration with a 3.81 mm pitch. The component utilizes direct-insert spring connection technology for wire-to-board interfacing, supporting rigid and flexible conductors within the 0.2 mm² to 1.5 mm² range. Rated at 8 A and 160 V (III/2), it employs hole-type contacts with tin plating. The housing is constructed from black PBT material, ensuring UL 94 V0 flammability compliance and a Comparative Tracking Index (CTI) of 400–600. Mechanical mounting is achieved via locking flanges, and the unit operates without additional latching mechanisms.

Feature Summary

• Direct-insert spring connection technology enables tool-free wiring termination for efficient assembly processes.
• CONNEXIS DD interlocking system provides secure mechanical engagement between mating components.
• Locking flange design ensures stable attachment to the printed circuit board during operation.
• Tin-plated copper alloy contacts offer reliable electrical conductivity and corrosion resistance.

Applications

• Cable assembly integration requiring optimized wire-to-board connections
• Industrial control systems utilizing low-voltage signal transmission
• Power distribution modules operating within specified current and voltage limits

Procurement Notes

Verify the complete part number including the suffix '-X' to ensure correct specification alignment. Confirm that the required conductor cross-sections fall within the 0.2 mm² to 1.5 mm² operational range. Ensure compatibility with the CONNEXIS DD mating system for proper interlocking functionality. Check environmental requirements against the RoHS and WEEE compliance standards documented in the official datasheet.

Selection Notes

Select this component when a 3.81 mm pitch and 8-position capacity are required for PCB mounting. Consider the direct-insert spring connection method if manual crimping tools are unavailable or if rapid assembly is prioritized. Evaluate the 160 V rating against the specific circuit voltage requirements. Ensure the black PBT housing meets the necessary thermal and flammability standards for the intended application environment.

Part Context

This connector belongs to the DD31PS 1,5/.. series within the broader CONNEXIS Connectors S lineup. It shares design characteristics with other variants such as the 6-position (1500432) and 20-position (1500441) models, differing primarily in contact count. The series is engineered for general industrial applications requiring robust signal and power transmission across various pitch options including 2.5 mm and 5.08 mm.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 3.81 mm pitch, 8-position layout, and CONNEXIS DD interface specifications exactly.

FAQ

What is the maximum recommended conductor cross-section for this connector?

The maximum recommended conductor cross-section is 1.5 mm² for both rigid and flexible wires.

Does this connector include an integrated locking mechanism?

No, the component does not include an integrated lock; it relies on the CONNEXIS DD interlocking system and locking flanges for stability.

What material is used for the contact surfaces?
