Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-5705ALZ is determined by the following critical parameters:

• Data Rate: 1.25Gbps
• Wavelength: 850nm
• Connector Type: LC Duplex
• Mounting Type: Pluggable, SFP
• Supply Voltage: 3.3V
• Application: Ethernet

The substitute part AFBR-5705ALZ-C, manufactured by ProLabs, maintains compatibility across these core electrical and mechanical parameters. This part is explicitly identified as an Avago AFBR-5705ALZ compatible transceiver module, confirming functional equivalence for the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-5705ALZ-C is a direct substitute for the obsolete AFBR-5705ALZ based on the following factors:

• Both parts operate at identical wavelength (850nm) and data rate (1.25Gbps)
• Both utilize LC duplex connectors in pluggable SFP form factor
• Both are classified under the same HTSUS commodity code
• The substitute part maintains active product status, ensuring ongoing availability
• RoHS compliance is maintained across both versions
• The substitute part is explicitly documented as Avago AFBR-5705ALZ compatible

Selection of the AFBR-5705ALZ-C eliminates obsolescence risk while preserving electrical and mechanical compatibility with existing Ethernet infrastructure designed for 850nm SFP transceivers.

Frequently Asked Questions (FAQ)

Q: What makes AFBR-5705ALZ-C a valid substitute for AFBR-5705ALZ?

A: The AFBR-5705ALZ-C maintains identical wavelength (850nm), data rate (1.25Gbps), connector type (LC), and mounting configuration (Pluggable SFP). Both parts are designed for Ethernet applications and share the same HTSUS classification, confirming functional equivalence.

Q: Why is the original AFBR-5705ALZ classified as obsolete?

A: Product obsolescence indicates that Broadcom Limited has discontinued manufacturing. The AFBR-5705ALZ-C, maintained in active status by ProLabs, provides continuity for applications requiring 850nm SFP transceivers.

Q: Are there packaging differences between these parts?

A: The original AFBR-5705ALZ uses standard packaging, while the AFBR-5705ALZ-C is supplied in retail package format. Both maintain identical electrical and mechanical specifications for SFP module installation.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant and share HTSUS code 8517.62.0090. The original part carries ROHS3 certification, while the substitute maintains RoHS compliance. REACH status for the original part is unaffected.

Q: Can AFBR-5705ALZ-C be used in existing systems designed for AFBR-5705ALZ?

A: Yes. The substitute part is explicitly documented as Avago AFBR-5705ALZ compatible, confirming direct interchangeability in Ethernet infrastructure requiring 850nm LC duplex SFP transceivers operating at 1.25Gbps.
