Features

 

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.

2x1 ganged SFP receptacle with integrated cage - compact dual-port front panel
Press-fit termination, through-hole right-angle mount for standard host PCB layouts
EMI spring finger shielding to help contain emissions at the module-bezel interface
Without lightpipe - clean cage profile when panel LEDs are handled separately
SFP MSA mechanical form-factor class, supporting SFP modules up to 4 Gb/s.
Operating range -40 to +85°C; outline approx. 63.25 x 14.00 x 25.50 mm (LxWxH)
Primary cross: Amphenol UE78-B1126-00321 - reduce second-source risk with a clear drop-in target

Compatibility Assurance

 

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)

Amphenol UE78-B1126-00321 - 2x1 SFP cage + receptacle class, EMI spring finger, without lightpipe
Form-factor fit: SFP MSA mechanical class - accepts standard SFP / SFP-family pluggable modules that mate to a 2x1 ganged cage (always verify latch, EMI gasket, and bezel stack-up on your host).
What we match: port matrix (2x1), press-fit / through-hole R/A mounting intent, EMI spring-finger style shielding, no lightpipe - aligned to the Amphenol target above.
Data rate: The specified 4 Gb/s maximum data rate refers to the maximum-rate module supported by LP21A602001, rather than a link rate generated by the cage itself. The actual link rate depends on the plugged module and host system.
Drawing first: confirm pin map, recommended PCB thickness, plating, and board-guide geometry on the LP21A602001 product drawing before release to production.

Applications

 

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.

Enterprise & campus switches Dual SFP uplinks or access ports on the same faceplate row without separate single cages.
Industrial / rugged Ethernet -40 to +85°C operating window for cabinets and edge devices that see wider ambient swings.
Media converters & NICs Compact 2x1 front-end when the design needs two pluggable optics or DAC/AOC ports.
OEM second-source builds Amphenol UE78-B1126-00321-oriented BOMs looking for a LINK-PP alternate with EMI spring fingers and no lightpipe.

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.


EMI & Design-In Notes

 

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.

Bezel & host layout checklist

1 Bezel cutout & stack-up - align opening, gasket, and spring-finger contact so fingers compress evenly on both ports; avoid paint or thick coatings on mating surfaces.
2 Chassis / PCB ground - provide a low-impedance return from cage ground features into the ground plane; follow press-fit via and keep-out guidance on the drawing.
3 Module EMI skirts - use MSA-compliant SFP modules with intact EMI springs; damaged module skirts defeat the cage design.
4 Adjacent ports - for 2x1 gangs, keep port-to-port metal continuity and avoid plastic gaps that break the shield wall between cages.
5 Lightpipe choice - this SKU is without lightpipe; if you need panel LED pipes, evaluate family options (e.g. LP21AC01201) rather than modifying this cage.

Questions & Answers

Ask a Question
No data
  • 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
