I found some, a diffrent make, and you need to cut one leg off (pin 3) and move pin 5 into pins 3 on the board, then solder a wire from the top of the chip to pin 5 on the board. It's really easy to do..

Honda uses a 5 pin high side switch in a lot of their OBD1 and OBD2 ECUs to control solenoids like auto trans and vtec solenoids.

Allegro / Sanken is the OEM for this part. The following parts are known to work:

SK-5050S (original - 1720 boards usually) SK-5151S (higher current version of 5050 - 11F0/1980 boards usually) SK-5154S (higher current version of 5151 - OBD2 boards usually) SI-5151S (part number change on SK-5151S) SI-5154S (part number change on SK-5154S) SI-5151SG (part number change on SI-5151S) SI-5154SG (part number change on SI-5154S) These parts are often quite difficult to get ahold of due to Allegro not selling less than 500pcs@$1.50ea and few electroncs distributors stocking them. Look for periodic groupbuys on the forum.
