VOOHU WH29BT019D1S01 as a Replacement for TE 2007637-5: 2×2 Stacked SFP+ Cage & Connector Assembly Comparison

1. Competitor Product Overview (TE Connectivity)

TE Connectivity is a leading global manufacturer of connectors, sensors and interconnect solutions. Its 2007637 series is a 2×2 stacked SFP+ shielding cage integrated with a press-fit connector, widely used in switches, servers and optical-module ports. This article compares the baseline part number TE 2007637-5: a 4-light-pipe, standard-EMI configuration. The cage is nickel-silver alloy (per ASTM B122) with 1.27µm min nickel plating all over; the housing and insert are black LCP (UL 94V-0); contacts are copper alloy with eye-of-needle press-fit termination, and the mating-interface finish conforms to TE product spec 108-2331 (based on EIA/ECA-364-1000.01A) with application spec 114-13219. Minimum PCB thickness is 1.5 mm; low CL/BR per TEC-138-702.

2. VOOHU Replacement Overview (Suzhou VOOHU Electronic Technology Co., Ltd.)

The WH29BT019D1S01 from Suzhou VOOHU Electronic Technology Co., Ltd. is an SFP+ 2×2 shielding cage integrated with a press-fit connector. Like TE 2007637-5, it is a 2×2 stacked SFP+ assembly with 20 pins per port and eye-of-needle press-fit termination; its port aperture (14.00±0.1 × 8.95 mm) and overall length (approx. 63.25 mm) match, making it a solid drop-in replacement. The cage is copper alloy with 30µ″ min nickel plating and 0.25 mm stock thickness; the housing is high-temperature LCP (UL94 V-0); the EMI springs are stainless steel (0.20 mm); the contacts are phosphor bronze (0.20 mm) with 15µ″ min gold on the mating area and 150µ″ min tin on the solder tails; the light pipes are clear polycarbonate. Operating temperature is −40°C to +85°C, storage temperature −55°C to +105°C, tray packaging, REACH & RoHS compliant.

3. Key Parameter Comparison

The table below uses the TE 2007637-5 customer drawing parameters as the baseline, with the corresponding VOOHU WH29BT019D1S01 specs filled in (only parameters specified by both and matchable one-to-one are listed; plating/temperature items given by only one side are covered in the Notes).

Notes:

1. Mating-area gold: VOOHU explicitly specifies 15µ″ min gold on the mating area (approx. 0.38µm); the TE customer drawing does not state a gold thickness, noting only that the contact finish conforms to TE product spec 108-2331 (per EIA/ECA-364-1000.01A, controlled-environment applications). Gold thickness is therefore not placed in the comparison table.
2. Solder-tail / needle-eye plating: VOOHU specifies 150µ″ min tin on the solder tails (approx. 3.81µm); TE 2007637-5 (Note 5) has tin on the needle eye, with no thickness stated. Both use tin-based tail plating, but TE gives no value, so it is not tabled.
3. EMI spring plating: the TE spring is 0.8µm min matte tin over 0.8µm min nickel; the VOOHU spring is stainless steel with no plating stated on the drawing.
4. Spring / contact stock thickness: VOOHU specifies spring 0.20 mm and contact 0.20 mm; the TE customer drawing does not state these values.
5. Cage stock thickness: VOOHU specifies 0.25 mm; the TE customer drawing does not state a cage stock thickness.
6. Operating / storage temperature: VOOHU explicitly specifies −40°C to +85°C operating and −55°C to +105°C storage; the TE customer drawing does not state a temperature range (refer to TE product spec 108-2331 if required).
7. Environmental / low halogen: TE states Low CL/BR (low chlorine/bromine per TEC-138-702); VOOHU states REACH & RoHS compliance. The two declarations differ in scope and are not merged into the table.
8. Enhanced-EMI variants: the TE 2007637 series also offers enhanced-EMI versions (part-number prefixes 1- / 3-) and different light-pipe options (none / inner 2 / outer 2 / 4); this article compares the baseline 2007637-5 (4 light pipes, standard EMI, active part).
9. Pin-out / footprint & mounting compatibility: both are 2×2 stacked SFP+, 20 pins per port, eye-of-needle press-fit per the SFP+ MSA mechanical interface, with matching port aperture and overall length; for actual replacement, verify PCB press-fit hole pattern, panel cutout and light-pipe positions before mass production.

4. Applications

1. 10G/25G SFP+ optical/electrical ports on data-center and enterprise switches and routers; 2×2 stacking increases faceplate port density.
2. High-speed interconnect ports on servers, storage (SAN/NAS) and network interface cards (NICs).
3. Pluggable optical-module ports on telecom/access equipment, OLT/ONU and transport gear.
4. Multi-port uplinks on industrial Ethernet switches, edge-computing and security-surveillance aggregation equipment.

5. FAQ

Q1: Can WH29BT019D1S01 directly replace TE 2007637-5?

Both are 2×2 stacked SFP+ assemblies with 20 pins per port and eye-of-needle press-fit termination per the SFP+ MSA mechanical interface; the port aperture (14.00±0.1 × 8.95 mm) and overall length (approx. 63.25 mm) match, and minimum PCB thickness is close (TE 1.5 mm / VOOHU 1.57 mm). Most designs achieve pin-to-pin and panel-cutout compatibility; verify the PCB press-fit hole pattern, panel cutout and light-pipe positions before mass production.

Q2: How do the two compare on shielding and thermal performance?

Both use a metal shielding cage with EMI springs to suppress SFP+ port EMI; the TE spring is tin/nickel-plated copper alloy, while the VOOHU spring is stainless steel. TE also offers enhanced-EMI versions (prefixes 1- / 3-); for higher shielding requirements, select accordingly or contact VOOHU for a custom option.

Q3: What are the gold/tin plating thicknesses?

VOOHU specifies 15µ″ min gold on the mating area and 150µ″ min tin on the solder tails; the TE customer drawing does not state a gold thickness (mating finish per product spec 108-2331) and uses tin on the needle eye. For specific plating requirements, request a custom solution from VOOHU.

Q4: What is the operating temperature range?

VOOHU explicitly specifies −40°C to +85°C operating (−55°C to +105°C storage), suitable for industrial-grade environments; the TE customer drawing does not state a temperature range—refer to its product specification if required.
