| Docking standards | QSFP MSA compatible module (TE 108-2286) | QSFP MSA compatible module (SFF-8663) |
| Cage shell wall thickness | 0.25 mm | 0.25 mm |
| Minimum PCB board thickness (single side) | 1.45 mm | 1.45 mm |
| Minimum PCB board thickness (double-sided/back-to-back) | 2.2 mm | 2.25 mm |
| Installation method | Through the panel; crimp pins + positioning guide posts + welding fixation | Through the panel; crimping (∅1.05) + positioning guide column + welding fixation |
| Positioning guide | Guide column (according to specification) | Guide column (according to specification) |
Note:
- Cage shell material: TE customer drawing indicates 0.25mm Nickel Silver; VOOHU is 0.25mm metal shielding cage shell. The specific alloy and surface treatment can be customized according to customer requirements, and the countersigned drawing shall prevail.
- Minimum PCB board thickness (double-sided): TE standard 2.2mm, VOOHU standard 2.25mm (back-to-back), the difference is 0.05mm, which is within the butt installation tolerance range.
- EMI shrapnel: TE is a copper alloy, with a surface of 0.8µm (minimum) tin plating and 0.8µm (minimum) nickel; VOOHU shrapnel has been cleaned and sealed, and the material and surface treatment can be customized.
- Termination and solder: TE uses Sn42Bi58 solder (6 places) with crimped pins; VOOHU uses crimped (∅1.05) with soldered fixed feet, and the solder grade is subject to countersign.
- Environmental protection: VOOHU complies with REACH and RoHS (2011/65/EU); TE customer drawings are not marked on the drawing.
- Please refer to the final drawings signed by both parties for pin definitions, guide pillar positions and panel openings.

5. Frequently Asked Questions (FAQ)
Q1: Are the panel openings and footprints of WH491U019D0S00 and TE 1888617-1 compatible?
Both are QSFP 1×1 through-panel cages. The cage wall thickness is 0.25mm, and the single/double-sided minimum PCB board thickness is consistent with the standard of 1.45/2.25mm. It is recommended to check the panel openings, guide posts and crimping holes 1:1 with the countersigned drawings.
Q2: What QSFP rates are supported?
The mechanical structure complies with QSFP MSA (SFF-8663) and is compatible with QSFP+/QSFP28 and other MSA modules; the specific speed depends on the supporting optical module and PCB design.
Q3: Can heat sinks or guide structures be installed?
The configuration of heat sinks, EMI springs and guide pillars can be customized as required; please provide application requirements for matching solutions.
Q4: Can the material and welding method be customized?
Can. The cage shell alloy, surface treatment of the shrapnel and the solder grade of the fixed feet can be customized according to the customer's requirements, subject to the countersigned drawing.
