Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFBR-5705LZ are identified based on strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Data Rate: 1.25Gbps
• Wavelength: 850nm
• Connector Type: LC (Duplex configuration)
• Mounting Type: Pluggable, SFP form factor
• Application: Ethernet

Secondary Compliance Criteria:

• RoHS compliance status
• HTSUS classification alignment
• ECCN export control classification

The AFBR-5705LZ-C qualifies as a substitute part because it maintains identical specifications across all primary compatibility criteria. Both parts operate at 850nm wavelength with LC connectors in the SFP pluggable form factor, ensuring direct compatibility with existing SFP port infrastructure.

Parameter Comparison

Engineering Selection Recommendations

AFBR-5705LZ-C (ProLabs) serves as the primary substitute for the obsolete AFBR-5705LZ. Selection of this substitute is based on the following engineering factors:

Compliance Alignment: Both parts maintain RoHS compliance, with the substitute meeting current RoHS standards. The identical HTSUS classification (8517.62.0090) confirms regulatory and tariff equivalence.

Product Status: The AFBR-5705LZ-C maintains active product status, ensuring ongoing availability and manufacturer support. This addresses the critical limitation of the obsolete AFBR-5705LZ, which is no longer in active production.

Optical and Electrical Compatibility: The substitute part maintains identical wavelength (850nm), connector configuration (LC), and SFP form factor specifications. These parameters ensure direct compatibility with existing optical network equipment designed for the original part.

Inventory Availability: The AFBR-5705LZ-C demonstrates substantial inventory availability (8443 units), supporting procurement requirements for both immediate replacement and future system expansion.

Frequently Asked Questions (FAQ)

Q: Can the AFBR-5705LZ-C be used as a direct replacement for the AFBR-5705LZ?

A: Yes. Both parts operate at 850nm wavelength with LC connectors in the SFP pluggable form factor. The electrical and optical specifications are equivalent, enabling direct substitution in Ethernet applications operating at 1.25Gbps.

Q: What is the significance of the part status difference (Obsolete vs. Active)?

A: The AFBR-5705LZ is classified as obsolete, indicating discontinued production and limited availability. The AFBR-5705LZ-C maintains active status, ensuring continued manufacturing, technical support, and reliable procurement channels for replacement and expansion requirements.

Q: Are there packaging differences between these parts?

A: Yes. The AFBR-5705LZ is supplied in bulk packaging, while the AFBR-5705LZ-C is supplied in retail packaging. This distinction affects procurement processes and inventory management but does not impact functional compatibility or optical performance.

Q: How do the RoHS compliance statuses compare?

A: The AFBR-5705LZ meets ROHS3 compliance, while the AFBR-5705LZ-C meets current RoHS compliance standards. Both parts satisfy RoHS requirements, with the substitute reflecting current regulatory standards.

Q: What connector configuration is used in these SFP modules?

A: Both parts utilize LC connectors in duplex configuration. The LC duplex connector standard ensures compatibility with standard SFP port interfaces used in Ethernet network equipment.

Q: Is the 3.3V supply voltage specification maintained in the substitute part?

A: The AFBR-5705LZ-C is specified as compatible with the AFBR-5705LZ, which operates at 3.3V. Compatibility across this parameter is implicit in the substitute designation and ensures proper operation within existing power delivery systems.
