APPLICATION SPECIFICATION
1.0 SCOPE
This Application Specification covers the performance requirements for the MINI-FIT TPA2 WireTo-Board and Wire-To-Wire, 4.20mm pitch dual row and single row connector series using brass,
phos bronze and high conductive copper alloy terminals with Tin and Gold plating terminated with 16
to 24 AWG wire using Molex crimp technology. The TPA Retainer (terminal position assurance) is
intended to ensure the crimp terminals are fully seated and to prevent incidence of terminal back-out
due to partially seated terminals. The connector position assurance (CPA) latch optional, will prevent
connector accidental un-mating. This document is NOT intended to be the final process definition nor
is it intended to constrain design.

5.0 CRIMPED TERMINAL EXTRACTION

website. Do not reuse terminals that have been removed with the extraction tool. The housings
can be reused if it was not damaged.

Note: Pictorial view shown for illustration purpose.
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 housing
pocket.

8.0 TERMINALS AND HOUSINGS
172718/202988 series terminals should only be used with Receptacle housing series’ 172708
(Dual row) and 200453 (Single Row).
172765/203070 series terminals should only be used with Plug housing series’ 172767 & 172762
(Dual row) and 200471 & 200488 (Single Row).
9.0 TERMINAL INSERTION INTO HOUSING
Terminals are to be inserted in the housing as shown below in Figure 1. Notice the orientation of
the stop tabs. Do not force terminals into the housing cavity. The terminal and housing are
designed with features that provide some light resistance during insertion as well as retention
after insertion but if excessive resistance is felt during insertion pull terminal back out and
double check that the terminal orientation is per Figure 1. Terminals are to be inserted until they
are fully seated as shown in Figure 2 and cannot fall out or be pulled out easily. The terminal
stop tabs provide a stopping surface and the locking tangs provide a light audible click to
indicate a fully inserted terminal.

11.0 TPA ASSEMBLY
TPA’s are to be inserted in the housing as shown below in Figure 3. The TPA’s are placed into the
housing at an angle and then pushed down to lock all in one motion. The TPA and housing are
designed with latches and locking features that hold the TPA in place after assembly. These features,
when used properly, provide an audible click to indicate proper installation. See Figures 4 and 5 for
proper TPA orientation after assembly. Be sure to check that both side latches have engaged. Figure
6 shows a failure mode where only one side of the TPA was engaged. In this case just push the TPA
a bit further to allow the other latch to engage. The TPA is NOT designed to increase terminal
retention in the housing. It is intended to ensure the crimp terminals are fully seated and to prevent
the incidence of terminal back-outs due to partially seated terminals.

12.0 CONNECTOR POSITION ASSURANCE (CPA)
Mini-Fit TPA 2 TPA (Series Number: 172709) is also available with a CPA part
(Series Number: 203603) for added mate assurance and secure locking.
12.1 Activating the CPA
Once the plug and receptacle is fully mated with TPA, simply push the CPA from “pre-lock” to
“final-lock” position until you see/feel positive engagement.

12.2 Deactivating the CPA
In order to operate the latch or un-mate the connector, the CPA must be deactivated. Pull the CPA
from “final-lock” condition to “pre-lock” condition with your finger. This sequence shall deactivate
the CPA, allowing the user to operate the latches and procede with the un-mating connector.

13.3 Crimp Terminal Handling
Due to exposed terminal interface, keep crimp terminals on prepackaged reel until they are
crimped onto wires. 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.
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.
Male and female crimp terminals are 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.
