Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the ABCU-5741RZ is determined by the following critical parameters:

• Data Rate: 1.25Gbd/1.25Gbps capability
• Connector Type: RJ45 interface
• Mounting Type: Pluggable SFP form factor
• Voltage Supply Range: 3.3V nominal operation
• Application Domain: Ethernet/Switch Interfacing

The substitute part ABCU-5741RZ-C meets these core requirements, operating at 1.25Gbps with RJ45 connector in SFP packaging. The voltage supply range of 3.3V ~ 4V encompasses the original 3.3V specification, ensuring electrical compatibility within standard operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The ABCU-5741RZ-C serves as a direct functional substitute for the obsolete ABCU-5741RZ. Both components share identical mechanical form factors (SFP pluggable), electrical data rates (1.25Gbps/Gbd), and connector specifications (RJ45). The substitute part operates within an expanded voltage supply range (3.3V ~ 4V) that includes the original specification, maintaining full compatibility with existing 3.3V systems.

The ABCU-5741RZ-C carries active product status with current inventory availability, eliminating supply chain constraints associated with the obsolete original part. Both components maintain RoHS compliance, satisfying environmental and regulatory requirements for industrial and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can ABCU-5741RZ-C directly replace ABCU-5741RZ in existing installations?

A: Yes. Both components feature identical SFP form factors, RJ45 connectors, and 1.25Gbps data rates. The substitute operates within a voltage range that encompasses the original 3.3V specification, ensuring electrical compatibility.

Q: What is the significance of the voltage supply range difference (3.3V vs. 3.3V ~ 4V)?

A: The ABCU-5741RZ-C accepts a wider input voltage range. Systems designed for 3.3V operation remain fully compatible, as 3.3V falls within the 3.3V ~ 4V acceptance window of the substitute part.

Q: Are there packaging differences between these parts?

A: The ABCU-5741RZ-C is supplied in Tray packaging, while the original ABCU-5741RZ packaging specification is not detailed. Both components use identical SFP pluggable form factors for installation.

Q: Why is the original part listed as obsolete?

A: The ABCU-5741RZ has reached end-of-life status with Broadcom Limited. The ABCU-5741RZ-C provides an active, currently manufactured alternative with equivalent electrical and mechanical specifications.

Q: Do both parts support the same application domains?

A: The ABCU-5741RZ targets switch interfacing applications, while the ABCU-5741RZ-C is specified for general Ethernet applications. Switch interfacing is a subset of Ethernet functionality, making the substitute suitable for the original application.
