SFP+ Cage: VOOHU WH291Z02SD0S02 Replacement for Pulse SFPPCAGE011-L — Comparison Report

1. Competitor Product Overview (Pulse Electronics, a YAGEO company)

Pulse SFPPCAGE011-L is a single-port SFP+ cage identified on the drawing as “SFP+ CAGE 1 BY 1, PRESS-FIT, FOR PCI.” Its Cage Top and Cage Bottom are listed as copper alloy with nickel finish, and the drawing is marked RoHS Compliant. The packaging information states 45 pieces per tray and 900 pieces per carton.

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

VOOHU WH291Z02SD0S02 is an SFP+ 1×1 metal cage in stainless steel with Ni plating; the drawing specifies a 0.25 mm cage thickness. It also states tray packaging, a −55°C to +85°C temperature range, and REACH & RoHS compliance. Both drawings concern single-port SFP+ cage solutions, but replacement design-in still requires verification of the press-fit/PCI requirement, PCB layout, bezel opening, chassis grounding, and sample assembly against the latest drawings.

3. Key Parameter Comparison

The table below uses the Pulse SFPPCAGE011-L drawing as the baseline and includes only structure, material, dimensional, and packaging items stated by both drawings and matchable one-to-one. Similar dimensions do not establish an unconditional direct-replacement or pin-to-pin compatibility conclusion.

Notes:

1. The Pulse drawing title explicitly includes “PRESS-FIT, FOR PCI,” while the VOOHU drawing title does not explicitly state PCI or press-fit. Although both are single-port SFP+ cages, confirm the actual mounting method and application structure.
2. Both drawings state cage length and front width, but the dimensional qualifiers differ: Pulse uses REF while VOOHU gives a tolerance. Similar dimensions do not replace CAD overlay, PCB review, or sample-assembly validation.
3. The VOOHU drawing states a 0.25 mm cage thickness and a −55°C to +85°C temperature range. The Pulse drawing does not provide directly corresponding thickness or temperature values, so these are not included in the table.
4. The Pulse drawing specifies 45 pieces per tray and 900 pieces per carton. The VOOHU drawing specifies tray packaging without a corresponding quantity; confirm current packing, MOQ, and quotation information before volume purchasing.

4. Applications

1. PCI network interface cards: for PCI cards with a single-port SFP+ pluggable optical-module interface, the drawings can support cage material, dimension, and installation-structure evaluation, including the press-fit requirement.
2. Server, storage, and NIC interfaces: when placing a single-port pluggable optical interface on a motherboard or interface card, evaluate PCB hole patterns, chassis grounding, and front-panel space together.
3. Industrial Ethernet and communications equipment: single-port SFP+ interfaces in industrial switches, routers, transport equipment, and security aggregation equipment can select a suitable cage scheme according to the target equipment's mechanical structure.
4. New design-in and existing-platform sourcing: when evaluating an existing Pulse solution for supply-chain alternatives, confirm structural suitability with the latest CAD, recommended PCB layout, bezel opening, and sample assembly.

5. FAQ

Q1: Can VOOHU WH291Z02SD0S02 directly replace Pulse SFPPCAGE011-L?

Both are single-port SFP+ cages and their materials, finishes, and drawing dimensions can be compared. However, the Pulse drawing explicitly states PRESS-FIT, FOR PCI while the VOOHU drawing does not use the same wording. This article does not establish a direct replacement; validate mounting, PCB, bezel, grounding, and sample assembly first.

Q2: How do the cage materials and surface finishes differ?

The Pulse drawing lists the Cage Top and Cage Bottom as copper alloy with nickel finish. The VOOHU drawing specifies stainless steel with Ni plating and states a 0.25 mm thickness. The material systems differ, so structural performance should follow the latest drawings and samples.

Q3: Does the VOOHU drawing state a temperature range?

Yes. The WH291Z02SD0S02 drawing specifies −55°C to +85°C. The Pulse SFPPCAGE011-L drawing does not state a directly corresponding temperature range, so this article makes no cross-product temperature-performance conclusion.

Q4: How should the packaging information be compared?

The Pulse drawing states 45 pieces per tray and 900 pieces per carton. The VOOHU drawing states tray packaging but does not state a quantity. For volume purchasing, use the current packing specification, MOQ, and quotation information.
