Key Features
- 3-pin polarized rectangular power connector plug preventing incorrect mating orientation
- Peg board-mounting option for secure mechanical retention on through-hole PCB assemblies
- Compact body (0.734 x 0.390 x 0.219 inch) suited for space-constrained power distribution blocks
- RoHS-compliant lead-free construction with 7-week standard factory lead time
Applications
The Molex 43650-0503 is designed for power distribution in automotive wiring harnesses, industrial control panels, and appliance power assemblies where a polarized 3-pin connector prevents mating errors. Its peg-mount design mechanically locks the housing to the PCB, reducing the risk of connector pull-out under cable tension or vibration in vehicle body control modules and motor drive boards. The rectangular plug format is compatible with the Molex Micro-Fit or equivalent receptacle families used widely in white goods and HVAC equipment.

Frequently Asked Questions
How does the polarized design of the Molex 43650-0503 prevent wiring errors during assembly?
The 43650-0503 incorporates a polarized plug body that allows mating in only one orientation with its corresponding receptacle. This physical keying across 3 pins eliminates the risk of reversing polarity or inserting an incorrect connector, which is critical in automotive and industrial power circuits where a miswired 12 V or 24 V connection could damage downstream electronics or create a fire hazard.
What are the physical dimensions of the 43650-0503 and how do they affect PCB layout requirements?
The 43650-0503 body measures 0.734 inches long, 0.390 inches deep, and 0.219 inches wide. These dimensions require a PCB footprint of approximately 18.6 mm x 9.9 mm for the housing, plus clearance for the 3-pin contact positions. Designers should plan at least 5 mm of clearance around the connector for cable routing and peg-hole drilling in the PCB substrate.
For which end-product categories is the Molex 43650-0503 most commonly specified?
The 43650-0503 is most commonly used in automotive body control modules, appliance power boards, HVAC control units, and industrial motor drive panels that distribute power through 3-circuit polarized connections. Its peg-mount retention suits vibration-prone environments, and the 3-pin layout handles typical power-plus-ground-plus-sense or dual-supply configurations found in 12 V and 24 V systems.
What lead time should procurement teams expect when ordering the Molex 43650-0503 in volume?
The Molex 43650-0503 carries a factory lead time of approximately 7 weeks from order placement. For production runs requiring more than a few thousand units of this 3-pin power connector, procurement teams should place orders at least 8 to 10 weeks in advance to account for shipping and incoming inspection time at the warehouse.
