The Molex 39-01-2245 is a 24-way, dual-row female receptacle housing from the Mini-Fit Jr. 5557 series, specified at a 4.2 mm (0.165 in) pitch to support mid-range power and signal interconnect applications. Designed to accept Mini-Fit Jr. crimp socket contacts, it supports up to 600 V and approximately 13 A per contact under typical conditions. The housing is moulded from UL94V-0-rated nylon (natural colour) for robust insulation and is rated for operation from -40 °C to +105 °C.

Standout Features and Benefits of Choosing the Molex 24-Way, 2 Row Female Connector Housing

Dual-row, 24-position configuration enables high-density connectivity in compact form.
4.2 mm pitch spacing supports reliable power and signal routing in moderate currents.
UL94V-0 nylon housing with a natural finish offers flame-retardant properties and insulation integrity.
Accepts Mini-Fit Jr. crimp socket terminals for consistent, low-resistance contact.
Withstands a wide operating range (-40 °C to +105 °C) for industrial and commercial use.

Reliable Interconnect Performance

This housing has been engineered for reliable interconnect systems that require compact size and current-handling capability. The 4.2 mm pitch helps balance between high signal/power density and manageable assembly. The UL94V-0 nylon body withstands elevated temperatures and potential exposure to mechanical stress, while the dual-row layout maximises circuit count without increasing footprint. Ideal for applications where serviceability, standardisation, and performance matter.
