Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-5921ALZ is determined by strict alignment of the following critical parameters:

• Data Rate: 2.125Gbps (exact match required)
• Wavelength: 850nm (exact match required)
• Voltage - Supply: 3.3V (exact match required)
• Connector Type: LC (duplex or standard LC acceptable for through-hole applications)
• Mounting Type: Through Hole (exact match required)
• Applications: General Purpose (functional category match)

The AFBR-5921ALZ-C meets all substitution criteria, maintaining identical electrical specifications and mechanical compatibility with the original component.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-5921ALZ-C is a direct electrical and mechanical substitute for the AFBR-5921ALZ. Both components share identical operational specifications: 2.125Gbps data rate, 850nm wavelength, 3.3V supply voltage, and through-hole mounting configuration.

The primary distinction is product status: the original AFBR-5921ALZ is obsolete, while the AFBR-5921ALZ-C maintains active production status. Both components maintain equivalent RoHS compliance certifications, with the substitute offering REACH Unaffected status. The substitute is available in tray packaging and demonstrates higher inventory availability, supporting continuity for legacy system applications.

Frequently Asked Questions (FAQ)

Q: Can the AFBR-5921ALZ-C replace the AFBR-5921ALZ in existing installations?

A: Yes. Both components operate at identical electrical specifications (2.125Gbps, 850nm, 3.3V) and share the same through-hole mounting configuration with LC connector compatibility. Electrical and mechanical substitution is direct.

Q: What is the significance of the connector type difference (LC Duplex vs. LC)?

A: The AFBR-5921ALZ specifies LC Duplex, while the AFBR-5921ALZ-C specifies LC. Both configurations support through-hole mounting and general-purpose transceiver applications. Connector compatibility must be verified against the specific system interface requirements.
