Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ABCU-5740ARZ is determined by the following critical parameters:

• Data Rate: 1.25Gbps (exact match required)
• Connector Type: RJ45 (exact match required)
• Mounting Type: Pluggable, SFP (exact match required)
• Voltage - Supply: 3.3V nominal (compatible range: 3.3V to 4V acceptable)
• RoHS Compliance: ROHS3 or equivalent RoHS standard

The substitute part ABCU-5740ARZ-C meets all substitution criteria through matching data rate, connector type, mounting type, and RoHS compliance status. The voltage supply range of 3.3V to 4V encompasses the original 3.3V specification.

Parameter Comparison

Engineering Selection Recommendations

The ABCU-5740ARZ-C is a direct substitute for the obsolete ABCU-5740ARZ based on matching electrical and mechanical specifications. The substitute part is currently in active production status with 8699 units available in inventory, compared to the obsolete status of the original part.

Both parts maintain RoHS compliance. The ABCU-5740ARZ-C operates within an expanded voltage supply range (3.3V to 4V) that includes the original 3.3V specification, ensuring compatibility with existing 3.3V supply designs. The identical data rate (1.25Gbps), connector type (RJ45), and mounting configuration (Pluggable, SFP) confirm functional interchangeability in switch interfacing applications.

Frequently Asked Questions (FAQ)

Q: Can ABCU-5740ARZ-C replace ABCU-5740ARZ in existing designs?

A: Yes. Both parts share identical data rate (1.25Gbps), connector type (RJ45), and mounting type (Pluggable, SFP). The substitute operates at 3.3V to 4V, which encompasses the original 3.3V specification.

Q: What is the primary reason for substitution?

A: The ABCU-5740ARZ is obsolete. The ABCU-5740ARZ-C is an active product with current inventory availability.
