Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-5750ALZ is determined by the following critical parameters:

• Wavelength: 1300nm (primary optical characteristic)
• Connector Type: LC Duplex (physical interface requirement)
• Mounting Type: Pluggable, SFP (form factor compatibility)
• Voltage Supply Range: Compatible with 3.1V ~ 4.6V operation
• RoHS Compliance: ROHS3 Compliant status
• REACH Status: REACH Unaffected

The identified substitute parts maintain compatibility across these core parameters while accommodating variations in data rate, applications, and product status. Substitutes are grouped based on their ability to function within the same physical slot and electrical environment as the original component.

Parameter Comparison

Engineering Selection Recommendations

HFBR-57E0ALZ is an active substitute manufactured by Broadcom Limited with ROHS3 compliance and REACH unaffected status. This part maintains 1300nm wavelength and LC duplex connectivity. The data rate of 155MBd is lower than the original 622Mbps specification, and the voltage supply is fixed at 3.3V within the original operating range. MSL rating of 1 provides superior moisture protection compared to the original MSL 3 rating. This substitute is suitable for applications where lower data rates are acceptable and active product support is required.

AFCT-5750ALZ-C is an active substitute from ATGBICS with higher data rate capability at 1.25Gbps and operates at 1310nm wavelength, which is within the 1300nm optical window. The voltage supply of 3.3V is compatible with the original range. The connector type is specified as LC without duplex designation. This substitute supports higher bandwidth applications while maintaining SFP pluggable form factor compatibility. MSL is not applicable for this part.

Both substitutes maintain SFP form factor and LC-based connectivity, ensuring physical compatibility with the original AFCT-5750ALZ slot configuration.

Frequently Asked Questions (FAQ)

Q: Can HFBR-57E0ALZ directly replace AFCT-5750ALZ in all applications?

A: Physical and electrical compatibility is maintained. However, the data rate difference (155MBd versus 622Mbps) must be evaluated against application requirements. The HFBR-57E0ALZ is suitable for lower-bandwidth Ethernet applications.

Q: What is the significance of the wavelength difference between 1300nm and 1310nm?

A: Both wavelengths operate within the same optical window for short-wavelength infrared transmission. The 1310nm wavelength of AFCT-5750ALZ-C is compatible with 1300nm-based infrastructure, though fiber dispersion characteristics may vary slightly.

Q: Does the MSL rating difference affect substitution suitability?

A: MSL ratings indicate moisture sensitivity during storage and handling. HFBR-57E0ALZ with MSL 1 (Unlimited) provides superior protection compared to AFCT-5750ALZ with MSL 3 (168 Hours). This is advantageous for long-term storage and humid environments.

Q: Are there voltage supply compatibility concerns?

A: The original AFCT-5750ALZ operates at 3.1V ~ 4.6V. Both substitutes operate at 3.3V, which falls within this range. Verify that the host system can supply stable 3.3V output.

Q: What is the impact of product status (Obsolete vs. Active)?

A: Active products (HFBR-57E0ALZ and AFCT-5750ALZ-C) have ongoing manufacturer support, availability, and potential design improvements. The obsolete status of the original part necessitates substitution for new deployments and long-term system support.

Q: How does the LC Duplex versus LC connector specification affect compatibility?

A: LC Duplex provides two separate LC connectors in a single housing for bidirectional communication. AFCT-5750ALZ-C specifies LC without duplex designation. Verify the host system's physical connector configuration before substitution.
