Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-57R5AEZ is determined by the following critical parameters:

• Data Rate: 4.25Gbps
• Wavelength: 850nm
• Voltage - Supply: 3.3V
• Connector Type: LC (Duplex or standard)
• Mounting Type: SFP or SFP+ pluggable form factor
• Applications: Ethernet or General Purpose
• RoHS Compliance: ROHS3 Compliant

Substitute parts must maintain compatibility across these electrical and mechanical specifications to ensure functional equivalence within Ethernet transceiver systems.

Parameter Comparison

Engineering Selection Recommendations

AFBR-57R5AEZ-C is the primary substitute candidate. This part maintains electrical equivalence with matching data rate (4.25Gbps), wavelength (850nm), and supply voltage (3.3V). Both parts are ROHS3 compliant. The AFBR-57R5AEZ-C is manufactured by ATGBICS and carries active product status, ensuring ongoing availability and support. The form factor transitions from SFP to SFP+, which represents a mechanical evolution within the pluggable transceiver category while maintaining LC connector compatibility.

AFBR-710FMZ is listed as a reference part only. Insufficient electrical parameter data (data rate, wavelength, voltage, connector type, and mounting type not specified) prevents direct substitution assessment. This part should not be selected as a replacement without complete technical specification verification.

Frequently Asked Questions (FAQ)

Q: Can AFBR-57R5AEZ-C directly replace AFBR-57R5AEZ in existing systems?

A: AFBR-57R5AEZ-C maintains electrical compatibility through matching data rate, wavelength, and supply voltage. The transition from SFP to SFP+ form factor requires physical slot compatibility verification. Both parts use LC connectors and support Ethernet applications at 4.25Gbps 850nm operation.

Q: What is the significance of the product status change from Obsolete to Active?

A: The AFBR-57R5AEZ-C active status indicates current manufacturing and availability. This addresses the obsolescence of the original AFBR-57R5AEZ and provides long-term procurement stability.

Q: Why is AFBR-710FMZ not recommended as a substitute?

A: Critical electrical parameters for AFBR-710FMZ are not specified in available documentation, including data rate, wavelength, voltage supply, connector type, and mounting type. Substitution cannot be confirmed without complete parameter alignment.

Q: Are there packaging differences between the main part and substitute?

A: AFBR-57R5AEZ is supplied in Bulk packaging, while AFBR-57R5AEZ-C is supplied in Tray packaging. This represents a logistics consideration only and does not affect electrical or mechanical compatibility.

Q: What compliance certifications apply to both parts?

A: Both AFBR-57R5AEZ and AFBR-57R5AEZ-C are ROHS3 compliant and share identical ECCN (5A991B4A) and HTSUS (8517.62.0090) classifications.
