Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-57D5APZ is determined by alignment of the following critical parameters:

• Data Rate: 8.5Gbps
• Wavelength: 850nm
• Supply Voltage: 3.3V
• Connector Type: LC (Duplex or standard)
• Mounting Type: Pluggable SFP or SFP+ format

The substitute part AFBR-57D5APZ-C, manufactured by ATGBICS, meets these core electrical and mechanical requirements. Both parts operate at identical data rates and wavelengths with matching supply voltage specifications. The connector type remains LC-based, and both utilize pluggable form factors compatible with standard SFP/SFP+ slots.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-57D5APZ-C serves as a direct substitute based on matching electrical specifications and form factor compatibility. The substitute part carries active product status, ensuring ongoing availability and manufacturer support. The ATGBICS part is RoHS compliant, providing environmental regulatory alignment for new designs and procurement cycles.

Both parts maintain REACH unaffected status, confirming compliance with chemical substance restrictions. The transition from SFP to SFP+ mounting format in the substitute part does not affect electrical compatibility, as both form factors operate within the same slot architecture for 8.5Gbps applications.

Frequently Asked Questions (FAQ)

Q: Can AFBR-57D5APZ-C replace AFBR-57D5APZ in existing systems?

A: Yes. Both parts operate at 8.5Gbps with 850nm wavelength and 3.3V supply voltage. The LC connector and pluggable form factor ensure mechanical and electrical compatibility in standard SFP/SFP+ slots.

Q: What is the difference between SFP and SFP+ mounting types?

A: SFP+ is a backward-compatible enhancement of the SFP form factor. Both fit standard SFP slots and support the same electrical interface. The AFBR-57D5APZ-C operates as an SFP+ module but maintains full compatibility with SFP-based systems.

Q: Why is the original part marked as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The AFBR-57D5APZ-C, with active status, provides continued availability for equivalent functionality.

Q: Are there compliance differences between the two parts?

A: The substitute part is RoHS compliant, whereas the original part does not specify RoHS status. Both maintain REACH unaffected classification. For new procurement, the RoHS-compliant substitute aligns with current environmental standards.

Q: What applications are supported by these parts?

A: The original part targets general-purpose applications. The substitute part is specified for Ethernet and networking applications at 8.5Gbps, covering the same operational bandwidth and wavelength range.
