AFBR-53D3FZ Equivalent & Substitute Parts

Part Overview

The AFBR-53D3FZ is a transceiver module manufactured by Broadcom Limited, designed for Ethernet applications operating at 850nm wavelength. This optical component features SC connector configuration with through-hole mounting and operates within a 4.75V to 5.25V supply voltage range. The product is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-53D3FZ is determined by the following critical parameters:

• Wavelength: 850nm (must match exactly for optical compatibility)
• Connector Type: SC (physical interface requirement)
• Mounting Type: Through Hole (PCB integration method)
• Supply Voltage Range: Compatibility within or encompassing the 4.75V ~ 5.25V specification

The identified substitute AFBR-53D3FZ-C shares the core optical and mechanical characteristics (850nm wavelength, SC connector, through-hole mounting) necessary for functional equivalence. However, voltage supply specifications differ between the main part and substitute, requiring evaluation based on system design parameters.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-53D3FZ-C is listed as an active product with current manufacturing status, providing supply chain continuity for the obsolete AFBR-53D3FZ. Both components share identical optical wavelength (850nm) and mechanical interface specifications (SC connector, through-hole mounting), establishing functional compatibility at the optical and physical levels.

The primary differentiation factor is supply voltage: the main part operates at 4.75V ~ 5.25V, while the substitute operates at 3.3V. Component selection must be based on system power supply architecture and voltage regulation capabilities. The substitute's RoHS compliance status and active product status provide advantages for new designs and long-term availability assurance.

Frequently Asked Questions (FAQ)

Q: Can AFBR-53D3FZ-C directly replace AFBR-53D3FZ in existing designs?

A: Direct replacement requires verification that system power supply can accommodate the 3.3V operating voltage of the substitute. The optical and mechanical interfaces are compatible; voltage compatibility must be confirmed through circuit design review.

Q: What are the critical parameters for optical transceiver substitution?

A: Wavelength, connector type, and mounting configuration must match exactly. For this product category, 850nm wavelength and SC connector are non-negotiable compatibility requirements.

Q: Why is the AFBR-53D3FZ obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The AFBR-53D3FZ-C represents the active equivalent in the product line.

Q: Does packaging affect substitution eligibility?

A: Packaging format (tray vs. other configurations) affects handling, storage, and procurement processes but does not impact electrical or optical functionality. System integration requirements should guide packaging selection.

Q: Are there compliance differences between the main part and substitute?

A: Both components maintain REACH Unaffected status. The substitute provides RoHS compliance certification, which may be required for specific applications or regional regulations.
