SFP 1×1 cage: VOOHU WH191R02SD0S02 replaces Pulse SFPCAGE002-L Comparison report

1. Introduction to friendly products (Pulse Electronics)

The SFPCAGE002-L from Pulse Electronics (a division of YAGEO Group) is a single-port SFP cage with Press-Fit structure. The drawing lists that the Cage Top and Cage Bottom are both made of copper alloy, with nickel surface treatment, and are RoHS compliant; the product is packed in pallets, with 45 pieces per pallet and 900 pieces per box.

2. Introduction to VOOHU alternative products (Suzhou VOOHU Electronic Technology Co., Ltd.)

The WH191R02SD0S02 of Suzhou VOOHU Electronic Technology Co., Ltd. (VOOHU) is a single-port SFP cage, using a stainless steel cage and Ni-plated surface treatment, pallet packaging, compliant with REACH and RoHS; the drawing indicates the operating temperature is −55℃~+85℃. It belongs to the same 1×1 SFP cage structure as Pulse SFPCAGE002-L. Before actual introduction, it still needs to be verified based on the PCB mounting holes, front panel opening and chassis grounding structure.

3. Comparison of core parameters

The table below is based on the Pulse SFPCAGE002-L drawing, and only lists items that are clearly marked on both drawings and can correspond one to one. Dimensions retain REF, brackets and qualifiers as shown in the drawing; the unit of the drawing is mm[inch].

Note:

1. 48.80 REF and (48.75), 15.0 REF and (15.10) are the reference dimensions in the two drawings respectively; the reference dimensions are close but do not mean they are directly interchangeable.
2. Both drawings give mechanical information such as PCB layout, no-go areas, front panels/openings, and mounting holes, but the datums, size sets, and detail annotations are different. Before importing the replacement, CAD overlays should be used to verify the PCB footprint, front panel openings, crimping/mounting holes, chassis ground pads, and component/trace prohibited areas one by one.
3. The Pulse drawing clearly says PRESSFIT; the VOOHU drawing is titled SFP 1X1 CAGE and gives the Recommended PCB Configuration. The actual installation process and the matching relationship with connectors and transceivers should be confirmed with the VOOHU engineering team during the project.
4. −55°C to +85°C is only seen in VOOHU drawings; the drawings provided by Pulse do not indicate the temperature range, so they are not used as a comparison of the temperature capabilities of both parties.
5. Both sides are marked with nickel surface treatment, but the base materials are copper alloy and stainless steel respectively; the material differences and their impact on the assembly reliability of the project need to be verified based on actual applications.

4. Applicable scenarios

1. Single-port SFP optical module interface for enterprise switches, routers, and industrial Ethernet switches.
2. Pluggable SFP optical module interfaces for servers, storage devices (SAN/NAS) and network interface cards (NICs).
3. SFP port design for telecommunications/access network equipment, transmission equipment and security monitoring and aggregation equipment.
4. When replacing existing equipment or importing new projects, you need to check the PCB mounting hole positions, front panel openings and chassis grounding structure items.

5. Frequently Asked Questions (FAQ)

Q1: Can WH191R02SD0S02 directly replace SFPCAGE002-L?

Direct alternative conclusions cannot be made based solely on the names and reference dimensions in the two drawings. Both are 1×1 SFP cage products, but the PCB layout, front panel openings, mounting holes and prohibited areas must be verified one by one, and sample assembly verification must be completed.

Q2: What are the differences in materials and surface treatments between the two?

The Pulse drawing lists both the upper and lower cages as copper alloy with nickel surface treatment; the VOOHU drawing lists stainless steel and Ni-plated. The material matrix is ​​different, and the mechanical performance cannot be judged to be the same based on the same nickel surface treatment.

Q3: Can the temperature ranges be compared?

The VOOHU drawings indicate a temperature range of −55°C to +85°C; the drawings provided by Pulse do not indicate a temperature range. Therefore, we cannot judge the temperature capabilities of both parties based on this.

Q4: What items should be checked first before importing substitutions?

It is recommended to use the latest drawings of both parties to conduct CAD overlays, verify the PCB footprint, front panel openings, mounting holes/crimp holes, chassis ground pads, components and wiring prohibited areas, and complete engineering verification based on the target connectors, transceivers and assembly processes.
