I’ll research JST’s specifications and verified alternatives, then write a cited application and usage guide in the project files, clearly flagging any unverified details.
JST’s current PH catalog specifies a wider temperature range than distributor listings for this exact ordering code; I’ll flag that discrepancy rather than assume interchangeability. I also verified two functional alternatives, but neither is confirmed as a drop-in replacement.
The JST B3B-PH-K-S(LF)(SN) is a three-position, single-row, vertical through-hole PCB header in the 2.00 mm-pitch PH wire-to-board connector family. Its common application is a detachable internal cable connection carrying low-voltage power and signals between a PCB and a peripheral or subassembly; JST identifies the PH family as a compact internal-wiring interface with friction-lock mating.

Rating terminology: JST publishes connector ratings and qualification tests, not a semiconductor-style “Absolute Maximum Ratings” table. Rated current and voltage are operating ceilings under their state...
Created and checked the Application & Usage Guide in the project files, covering all seven requested sections with citations and source links.
The guide flags conflicting temperature ratings and unverified drop-in compatibility; before design release, confirm the supplied-lot rating and validate pin orientation and footprint geometry.
