AFBR-5103PEZ Equivalent & Substitute Parts

Part Overview

The AFBR-5103PEZ is a transceiver module designed for Ethernet applications operating at 100Mbps with a 1308nm wavelength. The module features an SC connector and through-hole mounting, operating within a 4.75V to 5.25V supply voltage range. This part is classified as obsolete, making identification of suitable substitute components essential for system maintenance and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-5103PEZ is determined by the following critical parameters:

• Data Rate: 100Mbps (exact match required)
• Connector Type: SC (exact match required)
• Mounting Type: Through Hole (exact match required)
• Wavelength: 1308nm nominal (1300nm acceptable within optical specifications)

The substitute part AFBR-5103PEZ-C meets these core electrical and mechanical requirements. While the substitute operates at 3.3V supply voltage compared to the original 4.75V–5.25V specification, and is classified as active rather than obsolete, it maintains functional compatibility for 100Mbps Ethernet transceiver applications with SC connector and through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-5103PEZ-C is the designated manufacturer-recommended substitute for the obsolete AFBR-5103PEZ. Both parts maintain identical data rate (100Mbps), connector type (SC), and mounting configuration (through hole). The substitute is currently in active production status with RoHS compliance certification, providing supply chain continuity for applications requiring 100Mbps Ethernet transceiver modules with SC connectors.

The primary design consideration is the supply voltage differential: the original operates at 4.75V–5.25V while the substitute operates at 3.3V. System integration must account for this voltage requirement change during component selection and circuit design.

Frequently Asked Questions (FAQ)

Q: Can AFBR-5103PEZ-C directly replace AFBR-5103PEZ in existing designs?

A: Direct mechanical and optical replacement is possible due to matching SC connector type, through-hole mounting, and 100Mbps data rate. However, the supply voltage requirement differs (3.3V vs. 4.75V–5.25V), requiring circuit design evaluation before implementation.

Q: What is the wavelength compatibility between 1308nm and 1300nm?

A: Both wavelengths operate within the standard 1300nm window for Ethernet transceiver applications. The 8nm difference falls within acceptable optical specifications for this product category.

Q: Why is the original part classified as obsolete?

A: Obsolete status indicates the AFBR-5103PEZ is no longer manufactured by Broadcom Limited. The AFBR-5103PEZ-C represents the active production alternative for continued system support.

Q: What packaging differences exist between these parts?

A: The original part packaging is not specified in available documentation. The substitute is supplied in Tray packaging.

Q: Are both parts REACH compliant?

A: Yes, both the AFBR-5103PEZ and AFBR-5103PEZ-C are classified as REACH Unaffected.
