SFP+ 1×4 cage: VOOHU WH294T459D0S02 replaces Amphenol U77-A461M-X081 Comparison report

1. Product introduction of friendly merchants (Amphenol Canada Corp.)

The drawings provided by Amphenol Canada Corp. label U77-Ax61M-X081 as "1×N SFP+ Cage Assy. with Spring Finger Gasket". The series can be configured with 2, 4 or 6 ports; U77-A461M-X081 is the 4-port model shown. The drawings clearly indicate the copper alloy cage, pallet packaging, temperature range -40℃ to +85℃, and list the two plating options of nickel plating and matte tin.

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

VOOHU WH294T459D0S02 is "SFP+ 1X4 CAGE". The drawing indicates that the cage body is C7701 copper alloy with a material thickness of 0.25 mm and a nickel plating of not less than 20 μ″; the back spring is made of SUS304 stainless steel with a material thickness of 0.25 mm. This model is a 1×4 SFP+ cage with an operating temperature of -40°C to +85°C and a storage temperature of -55°C to +105°C, and is packaged in pallets.

3. Comparison of core parameters

The following table is based on the drawings of Amphenol U77-A461M-

Note:

1. The Amphenol drawings submitted are U77-Ax61M-X081 series drawings, covering 2, 4, and 6 ports. Since WH294T459D0S02 has a 1×4 structure, this article uses the 4-port model U77-A461M-X081 clearly listed in the figure as a comparison benchmark.
2. The port center distance, illustration height, operating temperature, and packaging method are the same on both sides; however, the total width of the 1×4 illustration is 56.75 mm and 57.25 REF mm, which is a 0.50 mm difference. It cannot be regarded as a direct replacement based on this alone. It needs to be confirmed in combination with the PCB, panel and complete machine structure.
3. The plating layer does not enter the comparison table: the plating level in the Amphenol material number is still Please confirm the actual ordered Amphenol coating code and VOOHU coating requirements before mass production.
4. Both parties provide recommended PCB/panel-related diagrams, but springs/finger springs, panel openings, positioning holes, PCB pads or crimping holes, and overall machine interference conditions should be reviewed with their respective drawings and physical samples.
5. The VOOHU drawings separately list the storage temperature -55℃ to +105℃; the Amphenol drawings provided do not have corresponding storage temperature labels, so this item does not enter the comparison table.

4. Applicable scenarios

1. Switches, routers and optical transmission equipment using 1×4 SFP+ optical module port layout.
2. Multi-lane SFP+ interconnect ports in servers, storage and data center equipment.
3. Multi-port SFP+ cage assemblies for industrial communications, security transmission and datacom equipment.
4. SFP+ optical port system that requires selection and verification based on PCB, panel and EMI spring/finger spring structure.

5. Frequently Asked Questions (FAQ)

Q1: Can VOOHU WH294T459D0S02 directly replace Amphenol U77-A461M-X081?

Both are 1×4 SFP+ cages, and the port center distance, illustrated height, operating temperature, and packaging method can correspond; however, there is a 0.50 mm difference in the total width of the drawings, and the spring/finger spring, PCB, and panel structures need to be reviewed. Therefore, it can be used as a comparison object for alternative selection, but the PCB layout, panel opening, positioning structure, module insertion and removal, and complete machine clearance verification must be completed before mass production.

Q2: Why choose U77-A461M-X081 as the benchmark material number of the friend?

The Amphenol drawings submitted are 2-, 4-, and 6-port shared series drawings; among them, U77-A461M-

Q3: Are the coatings of the two the same?

It cannot be directly determined to be the same. The Amphenol drawing lists two optional platings, nickel plating and matte tin, but the plating position of the material number shown in the picture is

Q4: What are the key items to confirm during substitution verification?

It is recommended to focus on checking the 1×4 overall width, PCB pad or crimp hole position, positioning holes, panel openings, spring/finger spring contacts, optical module insertion and removal, and interference with adjacent devices. The recommended structural drawings of both drawings should be used as the basis for sample verification.

Q5: What is the environmental compliance status?

Drawings submitted by both parties are marked REACH & RoHS Compliant. If the project has additional requirements for materials, coatings or testing documents, please confirm the corresponding information with VOOHU before mass production.
