Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ABCU-5730ARZ 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 (3.3V to 4V range acceptable)
• Form Factor: SFP module (standard compatibility)

The identified substitute parts meet all mandatory electrical and mechanical parameters. Both alternatives support 1.25Gbps Ethernet operation with RJ45 copper connectivity in standard SFP pluggable form factor, ensuring direct compatibility with systems designed for the ABCU-5730ARZ.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as active products with current manufacturing support, addressing the obsolescence status of the ABCU-5730ARZ.

ABCU-5730ARZ-C maintains identical core electrical specifications (1.25Gbps, RJ45, SFP pluggable) with extended voltage tolerance (3.3V to 4V), providing operational flexibility in systems with minor supply voltage variations. This part carries RoHS compliance certification and benefits from higher current inventory availability (10090 units).

FCLF8522P2BTL from Coherent matches the original part's ROHS3 compliance level and MSL rating. This option maintains strict 3.3V supply specification alignment with the original design and provides active product status with established supply chain presence (1120 units in stock).

Selection between substitutes should be based on system voltage tolerance requirements and preferred supplier qualification status.

Frequently Asked Questions (FAQ)

Q: Can ABCU-5730ARZ-C be used as a direct replacement in systems designed for ABCU-5730ARZ?

A: Yes. Both parts operate at 1.25Gbps with RJ45 connectors in standard SFP pluggable form factor. The ABCU-5730ARZ-C supports an extended voltage range (3.3V to 4V) that encompasses the original 3.3V specification, ensuring electrical compatibility.

Q: What is the difference between ABCU-5730ARZ-C and FCLF8522P2BTL?

A: Both are functionally equivalent 1.25Gbps SFP RJ45 transceiver modules. ABCU-5730ARZ-C offers wider voltage tolerance (3.3V to 4V) and higher inventory availability. FCLF8522P2BTL maintains stricter voltage specification (3.3V) and identical RoHS3/MSL compliance to the original part.

Q: Are there packaging differences between these substitutes?

A: Both substitute parts are supplied in tray packaging. The original ABCU-5730ARZ packaging specification was not provided. Verify tray packaging compatibility with your receiving and handling procedures.

Q: Do all three parts support the same Ethernet protocols?

A: All three parts operate at 1.25Gbps data rate with RJ45 copper connectivity, supporting standard Ethernet applications. The original part specified switch interfacing; substitutes are rated for general Ethernet applications, which encompasses switch interfacing functionality.

Q: Which substitute has better long-term availability?

A: Both ABCU-5730ARZ-C and FCLF8522P2BTL are classified as active products with current manufacturing support. ABCU-5730ARZ-C shows higher current inventory (10090 units versus 1120 units), suggesting stronger near-term availability.
