Should I keep these P-Channel Fets

[jblack741]

Had a large order from Mouser and ordered N-Channel fets (3034) and also received 2 of the following:

MOSFET 30V 6.2mohm @ 4.5V

Id - Continuous Drain Current: 18 A

Vds - Drain-Source Breakdown Voltage: - 20 V

Rds On - Drain-Source Resistance: 6.2 mOhms

Transistor Polarity: P-Channel

Vgs - Gate-Source Breakdown Voltage: 12 V

Maximum Operating Temperature: + 150 C

Pd - Power Dissipation: 3 W

Mounting Style: SMD/SMT

Package / Case: SOIC-Narrow-8

Packaging: Reel

Channel Mode: Enhancement

Configuration: Single Quad Drain Triple Source

Fall Time: 42 ns

Minimum Operating Temperature: - 55 C

Rise Time: 42 ns

Factory Pack Quantity: 2500

Typical Turn-Off Delay Time: 100 ns

I want to know if I can use them safely and if so what modification would I have to me to a Mosfet wiring to take advantage of them. Just seems a waste to have to send them back. Guidance helpful and appreciated...

Thanks in advance.
