LINK-PP LP21A602001 is a 2x1 ganged SFP cage + receptacle assembly with EMI spring fingers - Amphenol UE78-B1126-00321 compatible - built for press-fit, through-hole right-angle host boards where two SFP ports sit side by side.

Buying a cage alternate should feel predictable. LP21A602001 is positioned as a mechanical / interconnect alternate to Amphenol UE78-B1126-00321 for 2x1 SFP press-fit, right-angle host designs - so you can second-source with a clear OEM target P/N.
Primary compatible P/N (publish)
Designed for host boards that need two adjacent SFP ports in a single ganged cage - switching, access, industrial, and embedded networking where press-fit assembly and EMI control matter.
Application fit depends on your bezel, PCB thickness, and module mix - use the product drawing for design-in, then validate with your target SFP modules.
LP21A602001 includes EMI spring fingers on the cage to help maintain a conductive path between the plugged module and the host bezel / chassis ground. Good EMI results still depend on host layout - treat the cage as one part of the shielding system.

Authoritative dimensions & pin map: use the LINK-PP drawing - do not guess PCB thickness, plating, or press-fit depths from marketing copy alone.

Q: How is it mounted on the PCB? By J***y
A: Press-fit termination with through-hole, right-angle mounting for a ganged 2x1 port matrix. Follow press-fit process and keep-out guidance on the product drawing; recommended PCB thickness should be taken from the drawing / engineering (do not assume a value from sibling SKUs). By admin
Q: What is LP21A602001 compatible with? By J***r
A: The primary published cross is Amphenol UE78-B1126-00321 - a 2x1 SFP cage + receptacle with EMI spring fingers and without lightpipe. Always confirm pin map, PCB thickness, and bezel stack-up against the LP21A602001 drawing before production release. By admin
Q: What are the outline dimensions and temperature range? By J***t
A: Product page dimensions: approx. L 63.25 x W 14.00 x H 25.50 mm. Operating temperature −40 to +85°C. Use the drawing for tolerances, pin lengths, and any board-guide details. By admin
Q: What warranty, returns, and shipping apply? By M***s
A: Aligned with l-p.com policy for this product: 5-year warranty, 15-day returns and 15-day exchange (eligibility per return policy), and free shipping offers as shown on the live product page. Stock (~1300) and unit price (~US$4.7) can change - check the live page at order time. Wholesale and samples: sales@l-p.com. By admin
Q: What modules can I plug in? By N***n
A: Modules should be SFP form-factor pluggables within the published Data Rate (Max); validate latch feel, EMI skirt contact, and host EEPROM/protocol behavior in your system. Example companion on l-p.com: LS-MM852G-S3C 2.5G SFP. By admin
Q: Does LP21A602001 include a lightpipe? By C***t
A: No - this SKU is without lightpipe. If your front panel needs integrated LED pipes, consider family options such as LP21AC01201 (inner lightpipe) on l-p.com, and verify mechanical fit separately. By admin
Q: What about TE part numbers shown in some site assets? By G***y
A: Compatible brand chips may list TE, and some CDN filenames reference TE 1932709-2 / TE 2170282-1. Treat those as engineering-confirm items - they are not the primary Compatible P/N on the publish table. Primary customer-facing cross remains Amphenol UE78-B1126-00321 until engineering signs off TE footprint equivalence. By admin
Q: What does the "4 Gb/s" maximum data rate mean? By I***r
A: The 4 Gb/s maximum data rate refers to the maximum-rate SFP module supported by LP21A602001, rather than a data rate generated or independently determined by the cage itself. The cage provides the SFP mechanical interface, while the plugged module and host system determine the actual link data rate. By admin
