Automotive Connector Terminal – 1376109-1 / DJ629-0.7A, 0.7mm Female Crimp Contact

TE Connectivity 0.7mm female crimp terminals for high-density automotive connector systems. Part number 1376109-1 is the TE Connectivity catalog number; DJ629-0.7A is the Chinese standard equivalent. The 0.7mm contact size is used in high-density connector systems where circuit count requirements exceed what can be achieved with 1.2mm or 1.5mm pitch contacts. Common in modern vehicle ECU, transmission control, and body electronics applications where connector size is constrained but circuit count is high.

0.7mm vs 1.2mm vs 1.5mm Terminals — Pitch Comparison

• 1.5mm pitch: Standard for most automotive sensor and body electronics connectors. Adequate for most applications up to 20–30 circuits per connector.
• 1.2mm pitch: For higher density requirements. Used in ECU main connectors and high pin count body electronics.
• 0.7mm pitch (this product): Ultra-high density. For applications requiring 80–120+ circuits in a compact connector. Used in modern ECU, ADAS, and transmission control applications where connector size is strictly limited.

Frequently Asked Questions

What crimp tool is required for 1376109-1 terminals?

TE Connectivity specifies a dedicated micro-crimp tool for 0.7mm contacts. The correct tool produces a crimp that meets TE’s pull-out force specification for 0.7mm contacts. Using a standard automotive crimp tool will crush 0.7mm terminals. For professional ECU harness repair, use a pneumatic micro-crimp tool for the most consistent results on ultra-small contacts.

How do I extract 0.7mm terminals from a connector housing?

Use a micro terminal extraction pick sized for 0.7mm contacts. The pick must be thin enough to enter the housing cavity without damaging the cavity walls or adjacent terminals. Work under magnification — 0.7mm contacts are very small and the locking lance is difficult to see without magnification. Insert the pick from the mating face, depress the locking lance, and pull the wire from the rear.

Are gold-plated contacts required for 0.7mm terminals?

Gold plating is strongly recommended for 0.7mm signal contacts. At 0.7mm contact size, the contact area is very small — even a thin oxide layer significantly increases contact resistance. Gold plating prevents oxidation, maintaining the low contact resistance required for reliable signal transmission in ECU and sensor circuits. Tin-plated 0.7mm contacts are acceptable for power circuits but not recommended for low-level signal circuits.

Typical Applications

• ECU repair: High-density ECU connector terminal replacement
• Transmission control: TCM connector terminal replacement
• ADAS sensors: Camera and radar sensor connector terminal repair
• Automotive workshops: Workshop stock for high-density terminal repairs on modern vehicles
