AFCT-5750LZ Equivalent & Substitute Parts

Part Overview

The AFCT-5750LZ is a transceiver module manufactured by Broadcom Limited, designed for general-purpose optical communication applications. This SFP (Small Form-factor Pluggable) module operates at 622Mbps with a 1300nm wavelength and LC duplex connector configuration. The product is classified as "Not For New Designs," indicating it has reached end-of-life status. This obsolescence necessitates identification of functionally compatible substitute components for ongoing system maintenance and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the AFCT-5750LZ is determined by the following critical parameters:

• Connector Type: LC Duplex (physical interface requirement)
• Mounting Type: Pluggable, SFP (form factor and slot compatibility)
• Wavelength: 1300nm (optical transmission window)
• Voltage Supply Range: Must accommodate 3.1V ~ 4.6V operation
• Data Rate: 622Mbps minimum operational capability
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The HFBR-57E0LZ meets the core mechanical and optical interface requirements (LC Duplex connector, SFP form factor, 1300nm wavelength, ROHS3 compliance). However, differences in data rate specification and voltage supply rating require evaluation against specific system requirements.

Parameter Comparison

Engineering Selection Recommendations

The HFBR-57E0LZ is the identified substitute for the AFCT-5750LZ based on shared mechanical, optical, and regulatory characteristics. Both components feature identical connector types (LC Duplex), form factors (SFP), wavelengths (1300nm), and RoHS3 compliance status.

The HFBR-57E0LZ carries Active product status, ensuring continued availability and manufacturing support, whereas the AFCT-5750LZ is designated "Not For New Designs." This status difference makes the HFBR-57E0LZ the preferred choice for system continuity.

The voltage supply specification for HFBR-57E0LZ (3.3V) falls within the operational range of AFCT-5750LZ (3.1V ~ 4.6V), ensuring electrical compatibility with existing power delivery systems.

The data rate difference (155MBd for HFBR-57E0LZ versus 622Mbps for AFCT-5750LZ) must be evaluated against actual system bandwidth requirements. The lower data rate of the substitute does not preclude its use in systems designed for the original component's specifications, provided system architecture permits operation at reduced bandwidth.

Frequently Asked Questions (FAQ)

Q: Can HFBR-57E0LZ directly replace AFCT-5750LZ in existing installations?

A: Physical and electrical compatibility is confirmed through matching connector types (LC Duplex), form factors (SFP), wavelengths (1300nm), and voltage supply ranges. System-level validation is required to confirm data rate compatibility with application requirements.

Q: What is the significance of the data rate difference between these components?

A: AFCT-5750LZ operates at 622Mbps while HFBR-57E0LZ operates at 155MBd. The substitute component has a lower maximum data rate. Substitution is valid only if system bandwidth requirements do not exceed 155MBd.

Q: Are there voltage supply compatibility concerns?

A: HFBR-57E0LZ specifies 3.3V supply voltage, which is within the 3.1V ~ 4.6V range of AFCT-5750LZ. No voltage supply modification is required.

Q: What does the MSL rating difference indicate?

A: AFCT-5750LZ has MSL 3 (168-hour moisture sensitivity limit), while HFBR-57E0LZ has MSL 1 (unlimited). The substitute component has superior moisture resistance, reducing handling and storage constraints.

Q: Why is product status relevant to substitution decisions?

A: AFCT-5750LZ is "Not For New Designs," indicating end-of-life status and potential supply discontinuation. HFBR-57E0LZ is "Active," ensuring ongoing manufacturing availability and technical support.
