AFCT-5750TPZ Equivalent & Substitute Parts

Part Overview

The AFCT-5750TPZ is a transceiver module manufactured by Broadcom Limited, classified as a TXRX SFF OC12/STM-4 SR BAIL unit. This is a pluggable SFP (Small Form-factor Pluggable) transceiver designed for general-purpose optical communication applications operating at 622Mbps with 1300nm wavelength. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, legacy system support, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

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

• Connector Type: LC Duplex (required for physical compatibility)
• Mounting Type: Pluggable, SFP (required for form factor compatibility)
• Wavelength: 1300nm (required for optical compatibility)
• Voltage Supply Range: Compatible with 3.1V ~ 4.6V operating range
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute parts listed below maintain these core parameters while accommodating variations in data rate, applications, and manufacturer specifications.

Parameter Comparison

Engineering Selection Recommendations

HFBR-57E0PZ is an active product from Broadcom Limited with ROHS3 compliance and superior moisture sensitivity characteristics (MSL 1 vs. MSL 3). This substitute maintains the 1300nm wavelength and LC Duplex connector specification. The 155MBd data rate is lower than the original 622Mbps specification; this substitute is suitable for applications where lower bandwidth requirements exist or where backward compatibility with legacy Ethernet systems is required.

AFCT-5750TPZ-C is an active product from ATGBICS marketed as Avago Broadcom® Compatible. This substitute offers higher data rate capability (1000Mbps) and operates at 1310nm wavelength, which is within the standard 1300nm band tolerance for optical communications. The 3.3V supply voltage is compatible with the original 3.1V ~ 4.6V range. This substitute is suitable for applications requiring higher bandwidth capacity while maintaining SFP form factor and LC Duplex connectivity.

Frequently Asked Questions (FAQ)

Q: Can HFBR-57E0PZ replace AFCT-5750TPZ in all applications?

A: HFBR-57E0PZ maintains physical compatibility (LC Duplex, SFP form factor) and optical wavelength (1300nm). However, the data rate is 155MBd compared to the original 622Mbps. Substitution is valid only for applications where the lower bandwidth requirement does not impact system performance.

Q: What is the difference between 1300nm and 1310nm wavelengths?

A: Both wavelengths operate within the standard 1300nm band used for optical communications. The 10nm difference between 1300nm and 1310nm is within typical manufacturing tolerances and optical system specifications for SFP transceivers.

Q: Is AFCT-5750TPZ-C a direct replacement?

A: AFCT-5750TPZ-C is a compatible substitute that maintains the same form factor (SFP), connector type (LC Duplex), and supply voltage compatibility (3.3V within the 3.1V ~ 4.6V range). The higher data rate (1000Mbps) makes it suitable for applications requiring increased bandwidth. Compatibility depends on the specific system requirements and whether the higher data rate can be utilized.

Q: What does "Broadcom® Compatible" mean for AFCT-5750TPZ-C?

A: This designation indicates that ATGBICS has designed the AFCT-5750TPZ-C to be functionally compatible with Broadcom's SFP transceiver specifications, including physical form factor, electrical interface, and optical characteristics. Compatibility is based on adherence to SFP industry standards.

Q: Are there packaging differences between these substitutes?

A: Yes. AFCT-5750TPZ uses standard packaging, HFBR-57E0PZ is supplied in Bulk packaging, and AFCT-5750TPZ-C is supplied in Tray packaging. Packaging differences do not affect functional compatibility but may impact procurement quantities and handling procedures.

Q: Why is the original AFCT-5750TPZ obsolete?

A: Product obsolescence typically results from market transition to higher-capacity technologies or manufacturer discontinuation decisions. Active substitute products listed above provide equivalent or enhanced functionality for ongoing system support.
