When ordering, specify tolerance, termination and packaging codes: MSS7341-872NLD Tolerance: M = 20%, N = 30% (Table shows stock tolerances in bold.) Termination: L = RoHS compliant matte tin over nickel over phos bronze Special order: T = RoHS tin-silver-copper (95.5/4/0.5) over gold over nickel over phos bronze or S = non-RoHS tin-lead (63/37) over gold over nickel over phos bronze. Packaging: D = 13″ machine-ready reel. EIA‑481 embossed plastic tape (1200 parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.
