Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-5750ATPZ are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Connector Type: LC Duplex (required match)
• Mounting Type: Pluggable, SFP (required match)
• Wavelength: 1300nm (required match)
• Voltage Supply Range: Compatible with 3.1V ~ 4.6V operating window

Secondary Considerations:

• Data Rate: Substitutes may operate at different speeds while maintaining the same wavelength and connector specifications
• RoHS and REACH Compliance: All identified substitutes maintain ROHS3 Compliant and REACH Unaffected status
• Product Status: Active substitutes are preferred for ongoing availability

Two substitute parts meet the core compatibility requirements:

1. HFBR-57E0APZ (Broadcom Limited): Maintains 1300nm wavelength, LC Duplex connector, SFP form factor, and ROHS3 compliance. Operates at 155MBd with 3.3V supply.

2. AFCT-5750ATPZ-C (ATGBICS): Maintains LC connector, SFP form factor, and operates at 1310nm (within the 1300nm band). Operates at 1.25Gbps with 3.3V supply.

Parameter Comparison

Engineering Selection Recommendations

HFBR-57E0APZ Selection Criteria: This substitute maintains exact wavelength (1300nm) and connector specifications (LC Duplex) with Broadcom Limited manufacturing. Product status is Active, ensuring ongoing availability. ROHS3 compliance and REACH Unaffected status match the original specification. MSL rating of 1 provides superior moisture handling compared to the original MSL 3 rating. Data rate operates at 155MBd, which is lower than the original 622Mbps specification.

AFCT-5750ATPZ-C Selection Criteria: This substitute operates at 1310nm (within the 1300nm band) with LC connector and SFP form factor. Product status is Active with higher inventory availability (9078 Pcs). ROHS3 compliance is maintained. Data rate is 1.25Gbps, exceeding the original 622Mbps specification. MSL is Not Applicable, indicating superior moisture tolerance. Manufactured by ATGBICS rather than Broadcom Limited.

Both substitutes are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements. Selection between substitutes depends on system requirements for data rate compatibility and manufacturer preference.

Frequently Asked Questions (FAQ)

Q: Can HFBR-57E0APZ directly replace AFCT-5750ATPZ in all applications? A: HFBR-57E0APZ maintains identical wavelength (1300nm) and connector type (LC Duplex) with SFP form factor. The primary difference is data rate: HFBR-57E0APZ operates at 155MBd versus the original 622Mbps. Compatibility depends on whether the receiving system can operate at the lower data rate.

Q: What is the significance of the wavelength difference between 1300nm and 1310nm? A: Both wavelengths operate within the same optical window for short-range fiber optic transmission. The 1310nm wavelength of AFCT-5750ATPZ-C is within the standard 1300nm band and is compatible with systems designed for 1300nm operation.

Q: How do MSL ratings affect substitution decisions? A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be exposed to moisture before soldering. HFBR-57E0APZ has MSL 1 (Unlimited), providing superior moisture tolerance compared to the original MSL 3 (168 Hours). AFCT-5750ATPZ-C has MSL Not Applicable, indicating no moisture sensitivity constraints.

Q: Are both substitutes compatible with existing LC Duplex connectors? A: HFBR-57E0APZ features LC Duplex connectors, providing direct physical compatibility. AFCT-5750ATPZ-C features LC connectors (not explicitly Duplex), which may require verification for duplex system compatibility.

Q: What is the inventory status for these substitutes? A: HFBR-57E0APZ has 2300 Pcs available. AFCT-5750ATPZ-C has 9078 Pcs available. Both are listed as Active products with current stock.
