Micro-Fit+ Connectors

The Molex Micro-Fit+ Connector System builds on the proven reliability of the Micro-Fit 3.0 series, increasing customer efficiency in a wide range of industries. Micro-Fit+ products pair the 3.00mm pitch of Micro-Fit 3.0 Connectors with an increased current capability of up to 13.0A and up to a 40% reduction in mating force. Additionally, these connectors feature a smaller footprint than both Micro-Fit and Mini-Fit connectors. Leveraging Molex’s global manufacturing capability and robust engineering support, Micro-Fit+ Connectors are uniquely designed to meet the demands of power applications that require a compact, high-density solution without compromising performance or reliability.

Features and Benefits


Offering enhanced design and performance features, Micro-Fit+ Connectors boast a high current rating of up to 13.0A per circuit, combined with a reduced insertion force for easier assembly and an extended product life cycle. Designed to meet environmental, health and safety (EH&S) regulations and reduce mating force, operators benefit from easier assembly while increasing productivity and lowering risk of injury. These color-keyed connectors also offer manufacturers easy assembly with selective mating, helping to ensure that failure will not occur due to connector mis-mating.

Micro-Fit+ products are halogen-free and Glow Wire capable. This allows customers to adhere to environmental compliance and operator safety standards, including European regulations. These connectors also offer up to a 40% mating force reduction, minimizing operator fatigue for increased productivity.

Compatible with existing Micro-Fit 3.0 plug housings and with the added flexibility of a terminal position assurance (TPA) feature, Micro-Fit+ Connectors help ensure secure and proper terminal seating for robust connections in various applications. The connectors' fully isolated terminals provide superior electrical safety, making them suitable for a wide range of industries, including consumer home appliances, medical devices, automotive, and industrial control systems.

Optimal Space Savings

With its unique keying design, the Micro-Fit+ Connectors offer up to 13.0A with a 3.00mm pitch to deliver high current capacity for a diverse range of applications using the same amount of space that lower-current connectors occupy.

Frequently Asked Questions


Are Micro-Fit and Micro-Fit+ intermatable?​
No, they do not mate. The standard Micro-Fit product family and Micro-Fit+ product family do not mate together as they have different keying and polarization. ​ 

What is the benefit of using Micro-Fit+ over standard Micro-Fit?​ 
Micro-Fit+ has a higher current rating in a compact package, perfect for automotive or datacom end applications.​ 

Why would customers be interested in Micro-Fit+ having a lower mating force compared to standard Micro-Fit part numbers?​
Provides improved overall ergonomics within the connector system. A lower mating force is a design factor intended to maximize productivity by minimizing operator fatigue and discomfort.
