OBJECTIVE
This specification defines the performance, test, quality and reliability requirements of Crimp-to-Wire Mini-
PV (TM) receptacles and Mini-Latch housings.
2.0
SCOPE
This specification is applicable to the termination characteristics of the Crimp-to-Wire Mini-PV (TM) receptacles

5.2.2 Spring. The contact spring shall be Half-Hard, Beryllium Copper Alloy UNS C17200 in
accordance with ASTM B-194 heat treated to full hard condition.
5.2.3 Housing. The latch housings shall be of the material specified on the product
drawings.Materials shall have a flame retardant rating of UL94-V0.
5.2.4 Polarizing Plug. The plug shall be of the material specified on the product drawings.Materials
shall have a flame retardant rating of UL94-V0.
5.3
Finish
The finish for applicable components shall be as specified herein or equivalent.
5.3.1 Contact Body. As specified by the product drawings, the contact body shall be plated in the
contact area with the specified gold plating thickness per MIL-G-45204, Type II,Grade C over
50 microinches nickel per QQ-N-290,Class 2, or shall be plated with tin-lead in accordance
with ASTM B579. Lead free tin plating is also available, the material shall be hot dip tin coated
with a thickness of 100-160 micro inches.
5.3.2 Spring. The contact spring shall be plated with a flash of gold per MIL-G-45204, Type II, Grade C
over 50 microinches nickel per QQ-N-290, Class 2 or where specified on the product drawing with
tin-lead in accordance with ASTM B579. Lead free tin plating is also available, plated per GS-46-
001 (Confidential).
5.4
Design and Construction
Terminals and housings shall be of the design, construction and physical dimensions specified on
the applicable product drawing.
These crimp-to-wire terminals are designed to be either individually mated with pins without a
housing or inserted into a Mini-Latch or Rod Housing and connected to a header or bare pin field.
They are designed to crimp to discrete stranded 18 to 36 AWG wire. Hand tools and bench
mounted applicators are available for crimping terminals.
The terminals are available in a choice of spring thicknesses to provide several levels of contact
normal force.
5.5
Polarization/Keying/Latching.
Polarization and /or keying of the connector is accomplished through the use of individual polarizing
plugs inserted into selected contact positions. As an option, in some cases one or more housing
positions can be molded closed. In either case, the polarized position is rendered non-functional.
Special external polarization, keying and/or latching features are available depending on part
number and specific requirements.

Electrical Characteristics
6.1
Current Rating - The maximum current rating of the connector is dependent on wire size and
housing/circuit geometry. Figure 1 shows typical graphs of the temperature rise as a function of
current for various wire sizes. Figure1A shows typical graphs of temperature rise as a function of
current for various wire sizes as they were tested in a dense pack (2x36 position) housing. Figure 2
shows temperature rise profiles based on current applied. Charts for Figure 1 and 2 show test results
of PV's that were tested in a single position housing except for 18 and 20 AWG. These are not
recommended for use in a Mini Latch housing.
6.2 Contact Resistance, Low Level - After environmental testing, the change in contact resistance of the
mated connector shall not exceed 2 milliohms when measured in accordance with MIL-STD-1344,
Method 3002. The following details shall apply:
a. Method of Connection - Attach current and voltage leads as shown in Figure 3
b. Test Voltage - 20 millivolts DC max open circuit.
c. Test Current - Not to exceed 100 milliamperes.
6.3 Crimp Resistance, Low Level - When properly crimped, the change in crimp resistance shall not exceed
1 milliohms for wire sizes 18-30 AWG. The change in crimp resistance for 32-36 AWG shall not exceed
2 milliohms. Crimp resistance shall be measured in accordance with MIL-STD-1344, Method 3002. The
following details shall apply:
a. Method of Connection - Attach current and voltage leads as shown in Figure 3A.
b. Test Voltage - 20 millivolts DC max open circuit.
c. Test Current - Not to exceed 100 milliamperes.
6.4 Insulation Resistance - The insulation resistance of unmated terminals, properly mounted in Mini-Latch
housings, shall not be less than 10,000 megohms ( 5000 megohms after exposure to the humidity
environment described below) when measured in accordance with MIL-STD-202,Method 302. The
following details shall apply:
a. Test Voltage - 500 volts DC
b. Electrification Time - 2 minutes
c. Points of Measurement - Between adjacent and opposing contacts.
