Does JST offer loose piece versions of contacts on the carrier strip?

JST does not typically offer our strip terminals and chain terminals in loose piece (bulk) packaging. The reeled terminals are designed for large volume semi-automatic and fully-automatic wire termination equipment.

Hand tools are offered for loose contacts but most require the user to cut the terminal or contact off of the carrier strip before placing it into the hand tool for crimping.

Some of the JST authorized distributors do have the capabilities of removing the contacts from the carrier strip for those who wish to purchase loose contacts. Our network of authorized distributors can be found on our web site at the following URL:

USB Connector Part Number Changes

The following will explain the differences between the old and new, RoHS compliant USB Type A and Type B connectors:

Previous suffix of "-1":
Housing resin material = PBT
Shell = Nickel-undercoated, tin / copper alloy plating
Contact solder tail = 100% tin-plating (reflow treated)

Now changed to new suffix of "-4D":
Housing resin material = PBT
Shell = Nickel-undercoated, 100% pure tin-plating
Contact solder tail = 100% tin-plating (reflow treated)

************************************************

Previous suffix of "-2":
Housing resin material = PPS
Shell = Nickel-undercoated, tin / copper alloy plating
Contact solder tail = 100% tin-plating (reflow treated)

Now changed to new suffix of "-4S":
Housing resin material = PPS
Shell = Nickel-undercoated, 100% pure tin-plating
Contact solder tail = 100% tin-plating (reflow treated)

************************************************

Previous parts with a suffix of "-1NS" or without any designator have changed to "-4D" or "-4S" depending on the housing resin material.
