AFBR-5103Z Equivalent & Substitute Parts

Part Overview

The AFBR-5103Z is a transceiver module designed for general-purpose optical communication applications operating at 100Mbps with 1300nm wavelength. This component features an SC connector and through-hole mounting configuration, operating within a 4.75V to 5.25V supply voltage range.

The AFBR-5103Z is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure design continuity, and support ongoing production or maintenance requirements where original components are no longer readily available.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFBR-5103Z are identified based on the following critical parameters that determine functional compatibility:

• Data Rate: 100Mbps (exact match required)
• Wavelength: 1300nm (exact match required)
• Connector Type: SC (exact match required)
• Mounting Type: Through Hole (exact match required)
• Applications: General Purpose (exact match required)
• Voltage - Supply: Compatible with 5V operation (AFBR-5103Z operates 4.75V ~ 5.25V)

Two substitute parts meet these criteria: AFBR-5803Z (Broadcom Limited, manufacturer-recommended) and AFBR-5103Z-C (ATGBICS, compatible alternative).

Parameter Comparison

Engineering Selection Recommendations

AFBR-5803Z is the manufacturer-recommended substitute, produced by Broadcom Limited as an active product. This part maintains the same data rate, wavelength, connector type, and mounting configuration as the original AFBR-5103Z. The AFBR-5803Z offers improved moisture sensitivity characteristics (MSL 1 versus MSL 3) and RoHS3 compliance, supporting extended operational reliability and regulatory compliance requirements.

AFBR-5103Z-C is an active alternative produced by ATGBICS as a Broadcom-compatible component. This part meets all critical electrical and mechanical parameters for substitution. The ATGBICS part carries RoHS compliance and is available in higher inventory quantities. The connector designation specifies SC Duplex, which maintains compatibility with SC-based system architectures.

Both substitute parts are active products with established supply chains, contrasting with the obsolete status of the original AFBR-5103Z.

Frequently Asked Questions (FAQ)

Q: Can AFBR-5803Z directly replace AFBR-5103Z in existing designs?

A: Yes. Both parts operate at 100Mbps, 1300nm wavelength with SC connectors and through-hole mounting. The AFBR-5803Z supports 5V operation, which falls within the AFBR-5103Z supply voltage range of 4.75V ~ 5.25V. The AFBR-5803Z also supports 3.3V operation, providing additional flexibility for multi-voltage system designs.

Q: What is the difference between AFBR-5803Z and AFBR-5103Z-C?

A: Both parts meet the core electrical and mechanical substitution criteria. AFBR-5803Z is manufactured by Broadcom Limited and carries RoHS3 compliance with MSL 1 rating. AFBR-5103Z-C is manufactured by ATGBICS as a Broadcom-compatible alternative with RoHS compliance and higher available inventory. Selection depends on supply chain preferences and regulatory compliance requirements specific to the application.

Q: Are there packaging differences between these substitute parts?

A: Yes. AFBR-5103Z is specified with standard packaging. AFBR-5803Z is supplied in Bulk packaging. AFBR-5103Z-C is supplied in Tray packaging. Packaging selection should align with production volume requirements and handling procedures.

Q: Does the SC Duplex designation on AFBR-5103Z-C affect compatibility?

A: No. SC Duplex refers to the connector configuration supporting bidirectional optical transmission, which is consistent with the transceiver module function. This designation does not prevent substitution in systems designed for SC-based optical interfaces.

Q: What compliance certifications should be considered for substitution?

A: AFBR-5803Z provides RoHS3 compliance and REACH unaffected status. AFBR-5103Z-C provides RoHS compliance and REACH unaffected status. Both parts carry ECCN classifications appropriate for optical transceiver modules. Compliance requirements should be verified against specific application and regional regulations.
