I am looking to source a four-pin, 1.0 mm pitch, vertical JST connector -- either BM04B-SRSS-TB(LF)(SN) or BM04B-SRSS-TBT(LF)(SN). The latter has an extra 'Pick and Place' feature in Digikey. I can't find any info on JST's datasheet for the parts, nor can I find any info on the interwebs. There's a US$0.18 cost difference (the extra feature costing more, not surprisingly) between the parts.
What is this feature specifically? Can the connectors without this feature still be used in pick and place manufacturing?
