The S3B-PH-K-S(LF)(SN): Compared to the gold-plated sibling S3B-PH-K-S-GW, this tin-plated version is the cost-optimised choice for applications where mating cycle count stays below 50. The gold variant carries the same 2 A rating but offers higher corrosion resistance and longer cycle life. For a 2-position or 5-position option in the same orientation and plating, see S2B-PH-K-S(LF)(SN) and S5B-PH-K-S(LF)(SN) — identical pitch, current, and voltage ratings, differing only in circuit count.

Frequently asked questions
What is the closest functional second-source for S3B-PH-K-S(LF)(SN)?
The gold-plated variant S3B-PH-K-S-GW is the closest functional alternative — same 3 positions, 2.00 mm pitch, right-angle orientation, and 2 A rating. The only difference is the mating contact finish (gold vs tin), which affects corrosion resistance and mating cycle life.
Does S3B-PH-K-S(LF)(SN) mate with JST PH crimp housings?
Yes, it mates with JST PH series crimp housings such as PHR-3. The mating contact length is 0.130" (3.30 mm), and the detent lock engages with the receptacle latch for a secure connection.
