Product Details

Features Advantages Benefits
3.0 mm Pitch Compact Dual-Row LayoutOccupies significantly less PCB and panel space compared to traditional 4.2 mm pitch wire-to-board connectors.Enables engineers to design high-density electronic modules and downsized wire harnesses without sacrificing current capacity.
Fully Polarized & Keyed HousingPrevents misaligned insertion or cross-mating between the receptacle and headers.Eliminates human assembly errors on the factory floor, heavily reducing terminal damage and QA failure rates during production.
Integrated Positive Locking LatchDelivers an audible click when fully mated, ensuring a rugged, vibration-proof mechanical connection.Guarantees absolute signal stability and operational safety in harsh automotive, industrial automation, and power supply systems.
UL 94 V-0 Fire-Retardant NylonSelf-extinguishes within seconds during an electrical failure, meeting rigorous international safety baselines.Provides global compliance compliance, safeguarding high-temperature telecommunication and medical infrastructure applications.

Q1: What crimp terminals and mating headers are compatible with the Molex 43025-1800 housing?

A: The 43025-1800 receptacle housing is designed to be populated with Molex Micro-Fit 3.0 female crimp terminals (such as the 43030 series). For wire-to-board or wire-to-wire setups, it mates directly with Molex 43020 dual-row plug housings and Molex 43045 dual-row PCB headers. Matching terminal genders correctly is essential for proper electrical contact.

Q2: Does the 43025-1800 connector support mixed power and signal configurations?

A: Yes, the Micro-Fit 3.0 system is highly versatile. It can handle up to a 5.0 A current rating per circuit when paired with appropriate wire gauges (typically 20-30 AWG), making it an excellent choice for low-to-mid range power distribution as well as high-density signal routing within the same 18-pin block.

Q3: How does the positive locking latch on the 43025-1800 improve connection reliability?

A: The integrated mechanical latch provides a firm, physical lock when mated with a compatible plug or header. This mechanism prevents the connector from backing out due to mechanical stresses, shipping vibration, or handling. Workers will hear and feel an audible click, confirming that the connector is securely locked in place.
