Features
1. 5 Amps capacity
When used with 20 AWG wire, this connector has a
maximum capacity of 5A.
(For rated current with other types of wires, please refer to
the table on the next page)
Keying for multiple use
Standard type (Resin: White)
2. Secure lock mechanism
Outer locking mechanism prevents accidental unmating due
to external shocks or drops. (Fig.1)
3. Incorrect mating prevention
Two different housings, a standard and R type, are available
to ensure mis-mating does not occur when using multiple
DF33C connectors on the same design. (Fig.2)
R type (Resin: Black)
4. Accurate board placement
Guide posts are used to help with board placement and
prevent incorrect mating to the PCB.
5. Supports resin sealing
Accepts resin sealing up to 6.5mm without affecting the
performance.
6. Short circuit prevention
The housing protects each contact by enclosing them in a “box”
which also makes each contact independent of each other.
This design prevents short circuits between adjacent contacts.
7. Excellent contact retention
A retainer is available to increase contact/cable retention and
to assure complete contact insertion. The retainer should
also be used when any mechanical stress cold be applied to
the cable.
* The image on the left show header (the board
dip side), the image on the right show the
socket (cabel side).
* This guide key position is indicated in position
facing the mating surface of the header.
Fig.2
8. Prevents solder cracking
To avoid solder crack, a glass-filled resin is used in the
header housing to decrease thermal shrinkage.
9. Easy mating operation
A clear tactile click is delivered upon the completion of the
mating process. This simplifies mating and increases work
efficiency, especially when operating in a noisy environment.
10. Glow Wire compliance (Compliant with IEC 60695-2-11)
In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.

Note 1 : This is the maximum current rating while all pins are powered or used as all power lines.
If you split the current over multiple lines, please factor in your own safety margin. Please contact Hirose Electric for
inquiries on the assignment of pins and on the currents that can be delivered.
Note 2 : Includes temperature rise caused by current flow.
Note 3 : The connector should be completely dry. (no condensation present)
Note 4 : The term “storage” refers to the long-term storage condition of unused products before PCB mounting.
The operating temperature and humidity ranges are applied while in a non-energized state, while in transport or after PCB
mounting.
