What is clear: it ships in Tape & Reel packaging, which means it was designed for automated pick-and-place assembly lines, not hand-loading. The reel format is the first clue this is a surface-mount or small through-hole part intended for volume production, where every second of placement time matters.
Cross-Reference and Alternate MPN
The alternate order code 51338-4473 is a direct cross-reference — same series (*), same Tape & Reel packaging, same Active lifecycle status. The only difference is the dash in the part number formatting. For sourcing purposes, treat them as interchangeable: either MPN will get you the same component. If your BOM lists one and your supplier quotes the other, it's a clean match — no engineering review needed.
RoHS compliance is confirmed for this part — it meets the Restriction of Hazardous Substances directive, so it can be used in equipment sold into EU markets without exemption paperwork. The datasheet for the full series is available through the manufacturer's documentation portal; the product drawing will show the exact footprint, dimensions, and material callouts that this listing's spec table does not carry.
