AFBR-5715APZ Equivalent & Substitute Parts

Part Overview

The AFBR-5715APZ is a transceiver module manufactured by Broadcom Limited, designed for Ethernet applications operating at 1.25Gbps with 850nm wavelength. This SFP (Small Form-factor Pluggable) module features LC duplex connectors and operates at 3.3V supply voltage. The product is currently classified as obsolete, making identification of compatible substitute parts essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFBR-5715APZ are identified based on the following critical parameters that determine functional compatibility:

• Wavelength (850nm): Optical wavelength must match to ensure compatibility with existing fiber infrastructure and receiver optics
• Connector Type (LC Duplex): Physical connector interface must be identical for mechanical fit within SFP slots
• Mounting Type (Pluggable, SFP): Form factor must be SFP to ensure compatibility with standard SFP transceiver slots
• Voltage Supply (3.3V): Operating voltage must match system power delivery specifications
• Application (Ethernet): Functional category must remain within Ethernet transceiver classification

The FTLF8519P3BTL meets all critical substitution criteria. While this part operates at a higher data rate (2.125Gbps versus 1.25Gbps), it maintains backward compatibility through the same wavelength, connector type, mounting specification, voltage requirement, and application category. Higher data rate capability does not preclude use in lower-speed applications.

Parameter Comparison

Engineering Selection Recommendations

The FTLF8519P3BTL is available as an active product with current manufacturing support, whereas the AFBR-5715APZ is obsolete. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The substitute part's higher data rate specification does not create incompatibility with systems designed for 1.25Gbps operation, as SFP transceivers operate at the negotiated link speed of the connected equipment. Selection of the FTLF8519P3BTL provides access to an actively manufactured component with equivalent mechanical and electrical interface characteristics.

Frequently Asked Questions (FAQ)

Q: Can the FTLF8519P3BTL operate at 1.25Gbps in a system designed for the AFBR-5715APZ?

A: Yes. The FTLF8519P3BTL will operate at the data rate negotiated by the host equipment. Systems designed for 1.25Gbps operation will establish links at that speed with this substitute module.

Q: Are the physical dimensions and SFP slot compatibility identical?

A: Yes. Both parts use the standard SFP form factor with LC duplex connectors and are designed for insertion into identical SFP transceiver slots.

Q: Do both parts require the same 3.3V supply voltage?

A: Yes. Both the AFBR-5715APZ and FTLF8519P3BTL operate at 3.3V supply voltage and are compatible with systems providing this voltage specification.

Q: What is the significance of the higher 2.125Gbps data rate on the substitute part?

A: The higher data rate indicates the maximum speed capability of the FTLF8519P3BTL. This does not affect operation in 1.25Gbps systems, as the transceiver will function at the lower speed without performance degradation.

Q: Are both parts compliant with the same environmental and regulatory standards?

A: Yes. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited) and share identical HTSUS classification (8517.62.0090).
