1544968-1

Overview

The TE Connectivity AMP Connectors part number 1544968-1 is an automotive terminal tab belonging to the NG1 Plus series. It features a crimp termination method with tin plating on the contact surface. Designed for robust electrical connections, this component supports a current rating of 49 A and operates within a temperature range of -40°C to +150°C. The terminal is specified for use with wire gauges ranging from 20 to 22 AWG, utilizing a mating interface dimension of 0.64mm.

Feature Summary

• Crimping termination design ensures secure mechanical and electrical connection
• Tin-plated contact surface provides corrosion resistance
• High thermal stability suitable for demanding automotive environments

Applications

• Automotive wiring harnesses
• High-current electrical circuits
• Vehicle power distribution systems

Procurement Notes

Verify that the specific order matches the NG1 Plus series designation and 0.64mm contact size. Confirm the wire gauge compatibility aligns with the 20-22 AWG specification. Ensure the tin plating requirement meets the application's environmental needs. Check RoHS compliance status if restricted substances are prohibited in the target market.

Selection Notes

Select this terminal when a high-current capacity of 49 A is required for 20-22 AWG conductors. The wide operating temperature range up to 150°C makes it suitable for engine compartments or high-heat zones. Ensure the mating connector accepts the 0.64mm contact dimension. Verify that crimping tools compatible with this specific tab geometry are available for assembly.

Part Context

This component is part of the broader TE Connectivity AMP Connectors portfolio, specifically categorized under automotive terminals. It serves as a critical interconnect element within larger connector assemblies, providing the interface between wire conductors and mating receptacles. The NG1 Plus series is engineered for reliability in vibration-prone automotive applications.

Replacement Considerations

Direct substitutes include other NG1 Plus series tabs with identical 0.64mm dimensions and 20-22 AWG ratings. Ensure any replacement maintains the same crimp style and tin plating finish to preserve electrical performance and environmental resistance.
