Operating temperature −40℃~+85℃, storage temperature −55℃~+105℃, tray packaging, REACH & RoHS compliance.

#3. Comparison of core parameters

The following table is based on the parameters listed in TE 2007637-5 customer drawings, and corresponds to the specifications filled in VOOHU WH29BT019D1S01 (only parameters that are clearly marked by both parties and can be matched one-to-one are listed; only coating/temperature items with values given by one party are listed in the "Note" after the table).

1. 1.Gold plating on the contact surface: VOOHU clearly marked the 15µ″ min gold plating (≈0.38µm) on the mating surface; TE customer drawings did not directly mark the gold plating thickness, only indicating that the contact surface treatment “complies with TE product specification 108-2331, in accordance with EIA/ECA-364-1000.01A (controlled environment application)”, so the gold plating thickness is not included in the comparison table.
2. 2.Solder foot/pinhole plating: VOOHU solder pin 150µ″ min tin plated (≈3.81µm); TE 2007637-5 (Note 5) The pinhole end is tin-plated (Tin), and the thickness is not marked on the drawing. Both solder pins are tin-based plating, and are not included in the table because TE has no value.
3. 3.EMI shrapnel coating: TE shrapnel is 0.8µm min matte tin / 0.8µm min nickel (Matte Tin over Nickel); VOOHU shrapnel is made of stainless steel, and the coating is not marked on the drawing.
4. 4.Material thickness of shrapnel and terminal: VOOHU clearly marks 0.20mm for shrapnel and 0.20mm for terminal; TE customer drawings do not mark the corresponding material thickness values.
5. 5.Cage shell material thickness: VOOHU marks 0.25mm; TE customer drawings do not mark the cage shell material thickness value.
6. 6.Working/storage temperature: VOOHU clearly marks the working temperature −40℃~+85℃ and the storage temperature −55℃~+105℃; TE customer drawings do not mark the temperature range (if necessary, please refer to TE product specification 108-2331).
7. 7.Environmentally friendly/low halogen: TE marked Low CL/BR (low chlorine/bromine, according to TEC-138-702); VOOHU marked REACH & RoHS compliant. The environmental protection statements of the two are of different calibers and are not included in the comparison table.
8. 8.Enhanced EMI version: TE 2007637 series also has enhanced EMI shielding version (part number prefix 1- / 3-) and different lamp configurations (none / inner 2 / outer 2 / 4 lamps) optional; this article uses the baseline material number 2007637-5 (4 lamps, standard EMI, non-discontinued parts) for comparison.
9. 9.Pin/package and installation compatibility: Both are 2×2 stacked SFP+, 20 pin/port, pin eye crimping, follow the SFP+ MSA mechanical interface, and the port opening is consistent with the component length; actual replacement is subject to final verification of the PCB crimping hole position, panel opening and lamp position.

#4. Applicable scenarios

1. 1.10G/25G SFP+ optical/electrical ports for data centers and enterprise-class switches and routers, 2×2 stacking increases panel port density.

#5. Frequently Asked Questions (FAQ)

QCan WH29BT019D1S01 directly replace TE 2007637-5?

Both are 2×2 stacked SFP+, 20 pin/port, Eye-of-Needle press-fit structure, follow the SFP+ MSA mechanical interface, the port opening (14.00±0.1 × 8.95mm) is consistent with the component length (about 63.25mm), and the minimum PCB thickness is similar (TE 1.5mm / VOOHU 1.57mm). Most designs can achieve PIN-to-PIN compatibility with panel openings; it is recommended to final check the PCB crimping hole position, panel opening and lamp position before mass production.

QHow about the shielding and heat dissipation between the two?

Both are metal shielding cages with EMI shrapnel to meet the EMI suppression requirements of SFP+ ports; the TE shrapnel is tin/nickel-plated copper alloy, and the VOOHU shrapnel is stainless steel. TE also provides enhanced EMI (material number prefix 1- / 3-) version optional. If you have higher shielding requirements, you can select accordingly or consult VOOHU for customization.

QWhat is the thickness of gold plating/tin plating?

The VOOHU butt surface is 15µ″ min gold-plated, and the soldering feet are 150µ″ min tin-plated; TE customer drawings do not directly indicate the gold plating thickness (the contact surface is treated according to product specification 108-2331), and the pinhole end is tin-plated. If you have specific requirements for coating thickness, you can request a customized solution from VOOHU.

QWhat is the operating temperature range?

VOOHU clearly marks the operating temperature -40℃~+85℃ and the storage temperature -55℃~+105℃, which is suitable for industrial-grade environments. TE customer drawings do not indicate the temperature range. If necessary, please refer to its product specifications.
