Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-57D7APZ is determined by the following critical parameters:

• Data Rate: 8.5Gbps (exact match required)
• Wavelength: 850nm (exact match required)
• Voltage - Supply: 3.3V (exact match required)
• Connector Type: LC (compatible with LC duplex)
• Mounting Type: Pluggable, SFP/SFP+ form factor

The substitute part AFBR-57D7APZ-C, manufactured by ATGBICS, meets all critical electrical and mechanical parameters. Both parts operate at identical data rates, wavelengths, and supply voltages. 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-57D7APZ-C serves as a direct functional substitute for the obsolete AFBR-57D7APZ. Both parts maintain identical electrical specifications across data rate, wavelength, and supply voltage parameters. The substitute part carries active product status with RoHS compliance certification, providing advantages for long-term component availability and regulatory alignment.

The transition from SFP to SFP+ form factor in the substitute part represents a forward-compatible upgrade path. Both form factors utilize standard pluggable slots in networking equipment, with SFP+ providing enhanced capability while maintaining backward compatibility in most applications. REACH compliance status remains consistent between both parts.

Frequently Asked Questions (FAQ)

Q: Can AFBR-57D7APZ-C directly replace AFBR-57D7APZ in existing systems?

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

Q: What is the significance of the SFP to SFP+ form factor difference?

A: SFP+ is an enhanced version of the SFP standard, offering improved performance capabilities. The AFBR-57D7APZ-C (SFP+) is compatible with equipment designed for both SFP and SFP+ modules, providing flexibility in deployment scenarios.

Q: Why is the original AFBR-57D7APZ classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The AFBR-57D7APZ-C, with active product status, represents the current available alternative for equivalent functionality.

Q: Are there compliance differences between the two parts?

A: The AFBR-57D7APZ-C includes RoHS compliance certification, whereas the original part does not specify this status. Both parts maintain REACH Unaffected status. The substitute part's RoHS compliance may be advantageous for applications with regulatory requirements.

Q: What is the inventory status for these parts?

A: AFBR-57D7APZ has 2100 units available as new original stock. AFBR-57D7APZ-C has 7472 units available as new original stock, providing greater availability for procurement.
