BCM5488SA7IPB Equivalent & Substitute Parts

Part Overview

The BCM5488SA7IPB is an 8/8 transceiver interface circuit designed for full and half-duplex Ethernet applications in a 484-PBGA package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The BCM5488SA7IPB serves as a core interface component for Ethernet communication, and equivalent parts must maintain compatibility across electrical specifications, package dimensions, and functional parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the BCM5488SA7IPB is determined by the following critical parameters:

• Manufacturer and Base Product Series: Both the main part and substitute must originate from Broadcom Limited and share the BCM5488 base product number to ensure functional equivalence.
• Package Type: The 484-PBGA package specification is mandatory for mechanical and electrical compatibility with existing PCB layouts.
• Transceiver Configuration: The 8/8 driver/receiver configuration and Ethernet protocol support must be maintained.
• Duplex Capability: Full and half-duplex operation support is required for protocol compatibility.
• Regulatory Compliance: ECCN and HTSUS classifications must align to ensure compliance with export and trade regulations.

The BCM5488SA7IPBG qualifies as a direct substitute based on these parameters. While the substitute part is classified as active (versus obsolete), it maintains the same base product designation, package specification, and functional characteristics required for equivalent operation.

Engineering Selection Recommendations

The BCM5488SA7IPBG is the qualified substitute for the obsolete BCM5488SA7IPB. Selection is based on the following engineering criteria:

• Product Status Alignment: The substitute part is classified as active, ensuring continued availability and manufacturing support from Broadcom Limited, whereas the main part is obsolete.
• Regulatory Compliance: The substitute part carries ROHS3 compliance and REACH unaffected status, meeting current environmental and hazardous substance regulations. These certifications support long-term supply chain viability.
• Functional Equivalence: Both parts maintain identical electrical and mechanical specifications across all critical parameters, including the 484-PBGA package, 8/8 transceiver configuration, and Ethernet protocol support.
• Export Classification: Both parts share the same ECCN and HTSUS codes, ensuring no change to export control or tariff classification.

For new designs or system refreshes, the BCM5488SA7IPBG is the appropriate selection. For legacy system maintenance where the original BCM5488SA7IPB is no longer available, the BCM5488SA7IPBG provides direct functional replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can the BCM5488SA7IPBG be used as a direct replacement for the BCM5488SA7IPB without PCB modifications?

A: Yes. Both parts share identical package specifications (484-PBGA), pinout, and functional characteristics. No PCB layout changes are required for substitution.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The main part (BCM5488SA7IPB) is obsolete and no longer manufactured by Broadcom Limited. The substitute part (BCM5488SA7IPBG) is actively produced, ensuring reliable supply for current and future applications. For systems currently using the obsolete part, transition to the active substitute is recommended to avoid supply chain disruption.

Q: Are there any differences in electrical performance between these two parts?

A: No electrical performance differences are specified in the provided data. Both parts are 8/8 transceivers supporting full and half-duplex Ethernet operation with identical MSL ratings.

Q: Does the substitute part meet current environmental regulations?

A: Yes. The BCM5488SA7IPBG is ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance directives. The main part's compliance status is not specified in the available data.

Q: Are the ECCN and HTSUS classifications the same for both parts?

A: Yes. Both parts carry identical ECCN (5A991B1) and HTSUS (8542.39.0001) codes, ensuring no change to export control or tariff treatment.

Q: What inventory status should be considered when selecting between these parts?

A: The main part (BCM5488SA7IPB) has 835 units in stock, while the substitute (BCM5488SA7IPBG) has 8174 units available. The substitute's significantly higher inventory level reflects its active production status and suitability for ongoing procurement.
