Key distinction
External Mini-SAS uses a different mechanical interface from the internal SFF-8087 form.
External Mini-SAS HD must be distinguished from both internal SFF-8643 and legacy external SFF-8088.

TE Connectivity identifies SFF-8088 within its external Mini-SAS connector family.
Exact exampleTE1761987-7 only: the manufacturer EVERCLEAR brochure p.2 explicitly places this receptacle in External Mini-SAS/SATA applications. Its live product page lists right-angle surface-mount PCB termination, an LCP housing, phosphor-bronze contacts with gold mating plating and tin PCB-termination plating. This receptacle is supplied without a shell;1888321-1 is a separate shield accessory. These are component-scoped construction and mounting facts, with no pin map or universal cable capability asserted.
Claim scope: Only named TE Connectivity 1761987-7 component example. TE1761987-7 is an exact external Mini-SAS receptacle example. Do not transfer1888321-1 shield keying, screw-retention or one-row metadata to its contact arrangement. Brochure p.1 has an inconsistent Internal8088 bullet; the explicit p.2 external table controls only the application association. No face-view or numbered contacts are added.
Exact exampleTE2149027-1 is the1x1 receptacle assembly in the brochure p.6 external Mini-SAS HD family;1x1 describes ports. That external section specifies an LCP receptacle housing, nickel-silver shield, copper-alloy contacts and a preassembled one-piece PCB interconnect. It describes a cable latch and EMI skirt and publishes250-cycle durability for this external connector family. Internal SFF-8643 properties are excluded; this is source documentation, not hardware certification.
Claim scope: Only named TE Connectivity 2149027-1 component example. The2149027-1 example remains separate from internal P238/SFF-8643. Its1x1 value is a port matrix, not contact rows. The separate product page pitch.03mm[.75in] is inconsistent and remains withheld; no external pitch is borrowed from the internal section. Published family durability is not hardware validation.
Recorded evidence only. An inspection date, publisher label, source link or generated packet is not independent technical review, hardware testing, fabrication approval or a compatibility verdict.
