3.0 REFERENCE DOCUMENTS
See the appropriate sales drawings for information on specific part numbers and materials.
4.0 GENERAL APPLICATION NOTES
Appearance:
Parts conform to class "B" requirements of cosmetic specification PS-45499-002 except where
noted on the sales drawings.
Connector Application
This connector system is designed to mate gold plating to gold plating OR tin plating to tin plating.
Never cross mate tin plated parts to gold plated parts.
This connector system is not designed for current sharing (i.e. splitting one current load across
multiple circuits)
Connectors are not to be mated or unmated while circuits are live except per the current interrupt
rating listed in product specification: PS-76823-100
Packaging
The parts should remain in the original Molex packaging until ready for use to prevent damage.
Chemical Exposure
Do not store terminals or header assemblies near any chemicals listed below as they may cause
corrosion in the terminal contacts.

Crimped Terminal Extraction
Female terminal extraction tool: See Molex part# 638240800 instructions online on website. Do
not reuse terminals that have been removed with the extraction tool. The receptacle housing can
be reused if it was not damaged.
Connector Testing
Do not probe female terminal – use only Flat faced pogo pin styles that will not enter the terminal
opening.
Do not use Megafit connectors as test parts, they are not intended to be used with repeated mating.
Follow durability cycles as listed in PS-76823-100.
Crimped Terminal Insertion
Terminals are inserted in the same orientation for both top and bottom row. They should be
inserted square with the housing opening with the stop tabs pointed up and the lock tabs will be
facing the sides
Stop tabs
Lock
tabs
Ensure terminals are fully seated and locked during terminal insertion to the receptacle housing

Crimp Terminal Appearance
Forming marks on female terminal are normal. These are due to stretching of the plating during
the forming process and are superficial cracks on the plating surface.
Forming marks
Crimp Terminal Function
Do not use terminals with damaged lock tabs or damage on the front of the terminals:
Crimp Terminal Handling
Due to exposed terminal interface, keep crimp terminals on prepackaged reel until they are
crimped onto wires. Do not precut and bulk pack terminals due to risk of damaging the contact
interface. Store and handle crimped terminals so the interface does not make contact with other
terminals or foreign objects. If terminal interface is damaged please discard prior to assembly.

APPLICATION SPECIFICATION
Crimping
For acceptable crimp tools and specifications see application tooling section on Molex.com listed
for each terminal part number.
Use with multi strand wire only. Single strand wire should not be used.
This female crimp terminal is designed for single wire crimping only, no double wire crimping is
allowed.
Use only Molex specified crimp tooling, refer to Molex.com for acceptable crimp tooling. Crimped
terminals must also meet Molex crimp specifications. Using crimp tooling/specifications other
than specified voids any product warranties and will negatively impact mechanical and electrical
performance.
Header Appearance
Discoloration in the bandolier carrier area of the pin is inherent to the plating process and is due to
the masking effect of the carrier. This discoloration is in a non-functional area of the pin and will
not affect the performance of the header assembly. Refer to cosmetic specification PS-45499002.
Right Angle Header Appearance
Forming marks on header pins are acceptable. Refer to cosmetic specification PS-45499-002.
Header Assembly to Board
Headers are designed with press fit pegs and need to be pushed into the circuit board.
Alignment peg designed in for Headers without press fit pegs (crush pegs).
Header should be flush with board after insertion.
See below for solder process information.
Solder Process Temperatures
Wave Solder: 265°C Max
Reflow Solder: 260°C Max

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. 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.
Wires are to be dressed in such a manner to allow the terminals to float freely in the receptacle
pocket.
5.0 OPTIONAL STRAIN RELIEF HERMAPHRODITIC BACKSHELL
Appearance:
Parts conform to class "B" requirements of cosmetic specification PS-45499-002 except where
noted on the sales drawings.
Connector Application
This backshell is designed for cable strain relief.
Must be used with cable tie.
Can be used directly with wire bundle or wire bundle sheathing.
2 backshells per assembly (same part number).
Backshells not designed for re-use. If backshells are un-assembled for any reason then replace
both backshells with new backshells.
