AFBR-5205Z Equivalent & Substitute Parts

Part Overview

The AFBR-5205Z is a transceiver module designed for ATM/SONET/OC-3 applications operating at 155Mbps with 1310nm wavelength. This module features SC connector configuration and through-hole mounting, operating within a 4.75V to 5.25V supply voltage range. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-5205Z is determined by the following critical parameters: data rate (155Mbps), wavelength (1310nm/1300nm range), connector type (SC), and mounting type (through hole). The identified substitute parts maintain compatibility across these core electrical and mechanical specifications.

The AFBR-5805Z, manufactured by Broadcom Limited, operates at the same wavelength (1310nm) with identical connector and mounting configurations. However, this substitute operates at 3.3V supply voltage rather than the original 4.75V–5.25V specification, representing a voltage-level substitution suitable for systems with compatible power delivery.

The AFBR-5205Z-C, supplied by ATGBICS, maintains the 155Mbps data rate and 1300nm wavelength (within the 1310nm specification band) with matching SC connector and through-hole mounting. This substitute also operates at 3.3V supply voltage and is classified as active product status with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

Selection between substitute parts should be based on system power supply architecture and regulatory compliance requirements.

The AFBR-5805Z is suitable for applications where 3.3V supply voltage is available and data rate specification is not a critical constraint. This Broadcom-manufactured substitute maintains active product status and offers superior moisture handling characteristics (MSL 1 versus MSL 3), reducing storage and handling complexity.

The AFBR-5205Z-C is appropriate for applications requiring explicit 155Mbps data rate performance with 1300nm wavelength operation. This substitute provides active product status with RoHS compliance certification. The 3.3V supply voltage requirement must be accommodated within the system design.

Both substitutes require verification of system power supply compatibility, as the original AFBR-5205Z operates at 4.75V–5.25V while both alternatives operate at 3.3V.

Frequently Asked Questions (FAQ)

Q: Can the AFBR-5205Z be directly replaced with the AFBR-5805Z?

A: Direct replacement is possible if the system power supply can accommodate 3.3V operation. Both modules share identical SC connector type, through-hole mounting, and 1310nm wavelength. The primary consideration is voltage compatibility.

Q: What is the significance of the wavelength difference between 1310nm and 1300nm?

A: The 1300nm wavelength of the AFBR-5205Z-C falls within the standard 1310nm band used for long-distance fiber optic transmission. This 10nm variance is within acceptable tolerances for ATM/SONET/OC-3 applications.

Q: Why does the AFBR-5805Z not specify a data rate?

A: The AFBR-5805Z is classified for general-purpose applications rather than specific ATM/SONET protocols. Systems requiring guaranteed 155Mbps performance should prioritize the AFBR-5205Z-C, which explicitly specifies this data rate.

Q: What does MSL rating indicate for component handling?

A: Moisture Sensitivity Level (MSL) defines the maximum time a component can be exposed to ambient humidity before soldering. MSL 1 (unlimited) provides greater handling flexibility than MSL 3 (168 hours), reducing risk during storage and assembly operations.

Q: Are both substitute parts RoHS compliant?

A: Yes. The AFBR-5805Z is RoHS3 compliant, and the AFBR-5205Z-C is RoHS compliant. Both meet current environmental regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging formats are available for these substitutes?

A: The AFBR-5805Z is supplied in bulk packaging, while the AFBR-5205Z-C is supplied in tray packaging. Packaging selection should align with assembly process requirements and inventory management protocols.
