Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-57J7APZ is determined by the following critical parameters:

• Wavelength: 850nm (multimode fiber, short-reach applications)
• Data Rate Compatibility: Minimum 7Gbps to support the upper operational range of the original part
• Supply Voltage: 3.3V operation
• Connector Type: LC-based connectivity (LC Duplex or LC standard)
• Form Factor: SFP or SFP+ pluggable modules
• Application Scope: Wireless base station receiver or general-purpose optical transceiver use

The substitute part AFBR-57J7APZ-C meets these criteria through matching wavelength, voltage requirements, connector compatibility, and data rate capability.

Engineering Selection Recommendations

The AFBR-57J7APZ-C serves as the designated manufacturer-recommended substitute for the obsolete AFBR-57J7APZ. Selection of this alternative is supported by:

• Product Status Alignment: The substitute maintains active product status, ensuring ongoing availability and manufacturing support
• Electrical Compatibility: Both parts operate at 3.3V supply voltage with matching 850nm wavelength specifications
• Data Rate Coverage: The substitute's 7Gbps capability encompasses the primary operational range of the original part
• Connector and Form Factor: LC-based connectivity and SFP+ form factor provide mechanical and electrical compatibility within standard optical transceiver slot designs
• Compliance: ECCN classification as EAR99 indicates standard commercial availability without export restrictions

Frequently Asked Questions (FAQ)

Q: Why is the AFBR-57J7APZ classified as obsolete? A: The AFBR-57J7APZ has reached end-of-life status with Broadcom Limited. The AFBR-57J7APZ-C represents the active continuation of this product line.

Q: Are the SFP and SFP+ form factors mechanically interchangeable? A: Both SFP and SFP+ modules use the same mechanical slot design and are physically interchangeable in standard optical transceiver ports. The SFP+ designation indicates enhanced electrical performance capabilities.

Q: Does the substitute part support the full data rate range of the original? A: The AFBR-57J7APZ-C operates at 7Gbps, which covers the upper operational range of the original part (1.288 ~ 7.3728Gbps). Systems operating at lower data rates within this range remain compatible.

Q: What is the significance of the 850nm wavelength specification? A: The 850nm wavelength is optimized for multimode fiber transmission over short distances, typical in wireless base station receiver applications and local area network deployments.

Q: Are there differences in moisture sensitivity handling between the parts? A: The original part specifies MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The substitute lists MSL as Not Applicable, which is consistent with SFP+ module design standards and does not indicate incompatibility.
