Key Parameters

Substitute Part Grouping Explanation

Substitution for the ABCU-5731ARZ is determined by the following critical parameters:

• Data Rate: 1.25Gbps (required match)
• Connector Type: RJ45 (required match)
• Mounting Type: Pluggable, SFP (required match)
• Voltage - Supply: 3.3V nominal (compatible range: 3.3V to 4V acceptable)
• Applications: Switch Interfacing / Ethernet (functional compatibility)

The substitute part ABCU-5731ARZ-C, manufactured by ATGBICS, meets all critical electrical and mechanical parameters. This part maintains identical data rate, connector type, and form factor specifications while supporting an expanded voltage range of 3.3V to 4V, providing enhanced operational flexibility.

Parameter Comparison

Engineering Selection Recommendations

The ABCU-5731ARZ-C is a direct functional substitute for the obsolete ABCU-5731ARZ.
