Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-89CDHZ is determined by the following critical parameters:

Primary Compatibility Criteria:

• Wavelength: 850nm (multimode fiber operation)
• Connector Type: MTP® (MPO) interface
• Mounting Type: Pluggable QSFP28 form factor
• Applications: Ethernet transceiver functionality
• RoHS Compliance: ROHS3 Compliant

Secondary Compatibility Criteria:

• Data Rate: Minimum 100Gbps or higher
• Voltage Supply Range: Must accommodate 3.3V operation or overlapping range
• ECCN Classification: 5A991B1 (export control alignment)

The identified substitute parts meet all primary compatibility criteria and operate within acceptable data rate and voltage parameters for direct substitution in QSFP28 optical transceiver applications.

Engineering Selection Recommendations

FTLC9558REPM (Coherent): This substitute operates at 103.1Gbps with a supply voltage range of 3.135V to 3.465V, which encompasses the 3.3V specification of the AFBR-89CDHZ. The part maintains ROHS3 compliance and identical ECCN classification. Product status is Active, ensuring continued availability. Moisture Sensitivity Level is 1 (Unlimited), providing superior handling characteristics compared to the main part's MSL 3 rating.

JPQ81CS1MOC000SR4 (Jabil Photonics): This substitute operates at 103.125Gbps with a supply voltage range of 3.1V to 3.5V, which encompasses the 3.3V specification of the AFBR-89CDHZ. The part maintains ROHS3 compliance and identical ECCN classification. Product status is Active, ensuring continued availability. Moisture Sensitivity Level is 1 (Unlimited), providing superior handling characteristics compared to the main part's MSL 3 rating.

Both substitute parts satisfy all critical compatibility parameters and provide higher data rate capability with active product status, making them suitable for direct substitution in applications currently using the AFBR-89CDHZ.

Frequently Asked Questions (FAQ)

Q: Can FTLC9558REPM or JPQ81CS1MOC000SR4 be used as direct replacements for AFBR-89CDHZ?

A: Yes. Both substitute parts share identical wavelength (850nm), connector type (MTP® MPO), mounting type (Pluggable QSFP28), and application classification (Ethernet). Supply voltage ranges of both substitutes encompass the 3.3V specification of the main part. All parts maintain ROHS3 compliance and matching ECCN classification.

Q: What is the significance of the higher data rates (103.1Gbps and 103.125Gbps) on the substitute parts?

A: The substitute parts operate at data rates exceeding the 100Gbps specification of the AFBR-89CDHZ. This higher capability is backward compatible with 100Gbps system requirements and does not create incompatibility. The transceiver modules negotiate operating parameters with host equipment during initialization.

Q: How do the voltage supply ranges differ between the main part and substitutes?

A: The AFBR-89CDHZ operates at a fixed 3.3V supply. The FTLC9558REPM operates within 3.135V to 3.465V, and the JPQ81CS1MOC000SR4 operates within 3.1V to 3.5V. Both ranges include 3.3V within their operating windows, ensuring compatibility with systems designed for the main part's voltage specification.

Q: What is the difference in Moisture Sensitivity Level (MSL) between the main part and substitutes?

A: The AFBR-89CDHZ has MSL 3 (168 Hours), while both substitutes have MSL 1 (Unlimited). MSL 1 indicates superior moisture resistance and less stringent storage and handling requirements. This represents an improvement in component robustness for the substitute parts.

Q: Why is the AFBR-89CDHZ marked as Last Time Buy?

A: Last Time Buy status indicates that Broadcom Limited has discontinued production of this part. Identifying active substitute parts ensures system designers and procurement teams can transition to equivalent alternatives before the main part becomes unavailable in the supply chain.

Q: Are there any application differences between Ethernet and Telecom/Datacom Systems classifications?

A: The AFBR-89CDHZ is specified for both Ethernet and Telecom/Datacom Systems applications. The substitute parts are specified for Ethernet applications. Both classifications encompass high-speed optical data transmission in datacenter and telecommunications infrastructure, with Ethernet being the primary protocol for both use cases at 100Gbps speeds.
