Key Parameters

Substitute Part Grouping Explanation

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

• Data Rate: 1.25Gbps/1.25Gbd compatibility
• Connector Type: RJ45 interface requirement
• Mounting Type: Pluggable SFP form factor
• Physical Interface: Cat 5 cable transmission capability

The substitute part ABCU-5731RZ-C meets these core electrical and mechanical criteria. Both parts operate at equivalent data rates (1.25Gbd/1.25Gbps), utilize identical RJ45 connectors, and share the same SFP pluggable mounting configuration. The substitute maintains functional compatibility for switch interfacing and Ethernet applications requiring this transmission speed and connector standard.

Parameter Comparison

Engineering Selection Recommendations

The ABCU-5731RZ-C serves as a direct functional substitute for the obsolete ABCU-5731RZ based on electrical and mechanical parameter alignment. The substitute part maintains active product status with current manufacturer support, whereas the original part is obsolete and subject to inventory depletion.

Both parts satisfy RoHS compliance requirements, with the main part certified to ROHS3 and the substitute to RoHS standard. The substitute's active status and available inventory (8803 Pcs) provide supply chain continuity for applications requiring 1.25Gbps SFP RJ45 transceiver modules.

Selection between these parts should be based on application-specific requirements for supply availability and manufacturer support lifecycle. The substitute part is suitable for new designs and system replacements where the obsolete original part cannot be sourced.

Frequently Asked Questions (FAQ)

Q: Can ABCU-5731RZ-C directly replace ABCU-5731RZ in existing installations?

A: Yes. Both parts share identical data rate specifications (1.25Gbd/1.25Gbps), RJ45 connector type, and SFP pluggable form factor. The electrical and mechanical interfaces are compatible for switch interfacing and Ethernet applications.

Q: What is the primary reason for seeking a substitute?

A: The ABCU-5731RZ is classified as obsolete. The ABCU-5731RZ-C maintains active product status with current inventory availability and manufacturer support.

Q: Are there voltage supply differences between these parts?

A: The main part specifies 3.3V supply voltage. The substitute part does not specify a supply voltage parameter in available documentation. Verification of supply voltage compatibility with system requirements is necessary before deployment.

Q: What are the packaging differences?

A: The main part packaging is not specified. The substitute part is supplied in Tray packaging. This affects handling, storage, and integration into assembly processes but does not impact electrical or mechanical functionality.

Q: Do both parts meet RoHS compliance?

A: Yes. The main part is ROHS3 compliant. The substitute part is RoHS compliant. Both satisfy environmental and hazardous substance restrictions for their respective certification standards.
