Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BCM56520B0IFSBG is determined by the following critical parameters:

• Base product number alignment (BCM56520 series)
• Functional classification as a switch fabric component
• Interface type (PCI)
• Telecom application category
• Manufacturer (Broadcom Limited)

The substitute part BCM56520B0IFSBLG meets all substitution criteria through identical base product number, matching functional purpose, consistent interface specification, and common manufacturer origin. Both components serve equivalent roles within telecom interface switch applications.

Parameter Comparison

Engineering Selection Recommendations

Both the BCM56520B0IFSBG and BCM56520B0IFSBLG are classified as obsolete products. Selection between these components should be based on:

• Inventory availability and lead time requirements
• RoHS compliance requirements for the application (BCM56520B0IFSBLG carries ROHS3 Compliant certification)
• System integration constraints specific to the deployment environment

The BCM56520B0IFSBLG provides documented RoHS3 compliance, which may be advantageous for applications subject to environmental or regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can BCM56520B0IFSBLG directly replace BCM56520B0IFSBG in existing systems?

A: Yes. Both components share identical base product number (BCM56520), function (switch fabric), interface type (PCI), and manufacturer origin. They are functionally equivalent for telecom interface switch applications.

Q: What is the significance of the part number suffix difference?

A: The suffix variation (IFSBG versus IFSBLG) indicates packaging or certification differences. The BCM56520B0IFSBLG carries explicit ROHS3 Compliant designation, whereas the BCM56520B0IFSBG does not specify RoHS status.

Q: Are there inventory considerations for component selection?

A: Both parts maintain comparable stock levels (805 and 795 units respectively). Selection may depend on immediate availability and procurement timelines for your specific application.

Q: What parameters determine substitution eligibility for BCM56520 series components?

A: Substitution is valid when components maintain identical base product number (BCM56520), matching function (switch), consistent interface specification (PCI), and common manufacturer (Broadcom Limited).
