The JST SM02B-SFHLS-TF is a 2-position, single-row header from the SFH series, designed for board-to-cable/wire interconnects. It uses a 1.80 mm pitch and mounts as a right-angle surface-mount device, which keeps the mated cable parallel to the PCB — useful for low-profile harness routing near the board edge. The 4-wall shrouding and detent lock provide polarization and positive retention, so the mating receptacle won't back off under vibration or cable tug. Rated at 4 A per circuit with a 350 V voltage rating, this header handles moderate power levels typical of internal appliance wiring, LED lighting modules, or small sensor interfaces. The tin-plated copper alloy contacts are suited for applications with limited mating cycles — tin works well where the connector is mated a handful of times over its service life and the operating environment is clean and dry. The solder retention feature helps hold the part in place during reflow, reducing tombstoning or skew on the pick-and-place line. The yellow thermoplastic housing carries a UL94 V-0 flammability rating, which is a standard requirement for equipment inside an enclosure.
Mounting and Termination
This is a surface-mount, right-angle header with solder termination — no through-hole posts, so there is no secondary wave-solder step. The SMT footprint must match the 1.80 mm pitch and the 0.118" (3.00 mm) insulation height, which sets the standoff above the board. The right-angle orientation means the mating axis runs parallel to the PCB, which is a common requirement for board-edge connectors in space-constrained enclosures.
Mating and Compatibility
The SM02B-SFHLS-TF mates with JST SFH series receptacle housings that accept the matching crimp terminals. The detent lock on the header engages with the latch on the receptacle — you will hear and feel a click when fully seated. The 4-wall shrouding prevents misalignment during mating and protects the male pins from damage if the connector is handled before the harness is attached.
Sourcing and Lifecycle
The SM02B-SFHLS-TF carries an Active lifecycle status from JST — no end-of-life notice, no last-time-buy window. It is RoHS compliant.
