Suzhou VOOHU Electronic Technology Co., Ltd. (VOOHU)'s WH29BT019D1S01 is an integrated assembly of SFP+ 2×2 shielding cage and crimp connector. Like TE 2007637-5, it is a 2×2 stacked SFP+, 20 pin/port, pin eye crimp structure, port opening size (14.00±0.1 × 8.95mm) and component length (approx. 63.25mm) and can be used as a domestic alternative. The cage is made of copper alloy, 30µ″ (min) nickel plated, material thickness 0.25mm; the plastic case is high temperature LCP (UL94 V-0); the EMI spring is stainless steel (thickness 0.20mm); the terminal is phosphor bronze (thickness 0.20mm), the mating surface is 15µ″ (min) gold plated, the soldering pin is 150µ″ (min) tin plated; the light guide is made of transparent polycarbonate (PC). Operating temperature −40℃~+85℃, storage temperature −55℃~+105℃, tray packaging, REACH & RoHS compliance.
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).

Note:
Q1: Can 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.
Q2: How 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.
Q3: What 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.
Q4: What 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.
Q5: Does it support customization and proofing?
support. VOOHU is sold directly from the original factory and can be customized according to lamp configuration, coating thickness, packaging and other needs; sample orders are shipped within 48 hours and delivered within 7 days.
