Molex
SL TPA
What is a TPA?
VersaBlade • 15A maximum
• Meets appliance and automotive power requirements
• Positive latch
• Secure mating retention
• Ensures fully-seated terminal and prevents back-out
• Dual-row system
• Good heat dissipation and lower engagement forces
compared to 3-row systems
• Wide 1 .80mm ( .070") male tab contact
A secondary piece of the connector housing that is seated after the terminals are inserted into
the housing to assure that the terminals are properly positioned . IT aslo reinforces the locking
tang (the primary locking mechanism) that retains the terminal in the housing .
Why choose TPA?
Housings require terminals . The standard female terminal (70058) can be used; however, the
customer should also consider the high-force terminal (71851) .
It is important to protect high vibration application-oriented parts from fretting corrosion . Fretting
occurs when the terminal moves back and forth on the mating pin during vibration . Over time,
tin oxidation builds up at the mating interface and creates an intermittent circuit . The high-force
terminal grabs hold of the mating pin and is less likely to create tin oxidation .
To further protect against fretting, high-force terminals should be considered . Furthermore, the
implementation of gold contacts is essential to prevent oxidation, as gold does not oxidize .
Molex offers male terminals and housings or PCB headers to mate with the TPA connector
(wire-to-wire and wire-to-board) .
