Molex-Type Female Crimp Terminal (3.96mm Pitch) Crimp UC 391

Description

The Molex-Type Female Crimp Terminal (3.96mm Pitch) is the industry standard for creating secure, polarized wire-to-board connections in higher-current applications. Measuring at a wider 3.96mm (0.156") pin spacing compared to standard 2.54mm headers, these terminals and their corresponding housings are designed to handle thicker wire gauges and carry more power safely.

Available for your inventory at Tomson Electronics, this open-barrel crimp terminal is specifically engineered to lock into Molex-style housings (such as the KK 396 series). The terminal's metal retaining tang clicks securely into the plastic housing, ensuring a vibration-proof connection that cannot be plugged in backward. When crimped properly, it grips both the wire strands and the insulation, providing superior mechanical strength and vital strain relief for demanding power lines.

⚠️ IMPORTANT ORDERING NOTE: This product in multiples of 50. A single crimp lug is considered as a single unit listed on the website, irrespective of the quantity displayed in the product images (such as strips or reels).

Frequently Asked Questions (FAQ)

Q: Will these fit into a standard 2.54mm Molex or Dupont housing?
A: No. These are 3.96mm (0.156") terminals, which are physically wider and longer than 2.54mm (0.1") terminals. They must be used with matching 3.96mm pitch housings.

Q: The product image shows a long strip of terminals. Does one unit equal one strip?
A: No. A single, individual metal crimp lug is considered as a single unit on our website, regardless of how they are pictured in strips or reels. You must order a minimum of 50 units (50 individual lugs) for this item.

Q: What crimping tool do I use for these?
A: Because these accommodate thicker wire (like 18 AWG) and are physically larger, you will need a ratcheting open-barrel crimping tool with wider jaws (such as the SN-48B or SN-28B, depending on the wire gauge used) to get a clean, professional crimp.
