The XA series offers 4-position (BM04B-XASS-TF(LF)(SN)) and 6-position (BM06B-XASS-TF(LF)(SN)) variants with identical pitch, current rating, and SMD footprint. The 5-position part fills the gap between them — useful when a harness needs exactly five circuits without wasting a position or requiring a second connector.","metaTitle":"BM05B-XASS-TF(LF)(SN) JST XA 5-Pin Header SMD 2.5mm","metaDescription":"JST XA series 5-position SMD header, 2.50mm pitch, 3A, 250V, shrouded with locking ramp.
