4.1 VOLTAGE
600 Volts AC (RMS) (or 600 Volts DC)
*Voltage rating based on UL 1977. Maximum voltage allowed may vary dependent upon “End
Use Application”. Refer to the applicable end use standard for additional information on Voltage,
Creepage and Clearance requirements.
4.2 APPLICABLE WIRES
Maximum Insulation Diameter
and
Applicable Wire Gauges
16 AWG Standard, Copper: 3.15 mm / .124 inches MAXIMUM
18-24 AWG Standard, Copper: 3.10 mm / .122 inches MAXIMUM
22-28 AWG Standard, Copper: 1.80 mm / .071 inches MAXIMUM
4.3 MAXIMUM CURRENT RATING (Amperes)**
Note: PCB trace design may greatly affect temperature rise results in Wire-to-Board Applications.
** Current rating is application dependent and may be affected by the wire rating such as listed in UL-
60950-1. Each application should be evaluated by the end user for compliance to specific safety agency
requirements. The ratings listed in the chart above represents the MAXIMUM current carrying capacity of a
fully loaded connector with all circuits powered using tinned copper conductor stranded wire per Molex test
method based on a 30º C maximum temperature rise over ambient temperature and are provided as a
guideline. Appropriate de-rating is required based on circuit size, ambient temperature, copper trace size
on the PCB, gross heating from adjacent modules/components and other factors that influence connector
performance. Wire size & stranding, tin coated or bare copper wire, wire length & crimp quality are other
factors that influence current rating.

Testing sequences to be performed in accordance with EIA-364-1000.01
8.0 PACKAGING
Parts shall be packaged to protect against damage during handling, transit and storage.
Nylon parts should remain in there original packaging until ready for use to prevent moisture loss or
gain. Nylon will absorb moisture which causes dimensions to increase. Excess moisture gain can
result in dimensions exceeding specification.

The “T” dimension defines a “free” length of wire, or a length of wire that is not subject to
significant bias by external factors such as a wire tie, wire twisting, or other means of
bending or deforming of the wires that repositions them from their natural relaxed state
or location where they enter the housing. Wires are to be dressed in such a manner
to allow the terminals to float freely in the pocket. This dimension is a general recommendation
and may need to be adjusted for different wire gauges and wire type and insulation
thickness and insulation material.
