BCM5481A2KMLG Equivalent & Substitute Parts

Part Overview

The BCM5481A2KMLG is a single-port Gigabit Ethernet PHY (Physical Layer) interface IC with RGMII copper connectivity, manufactured by Broadcom Limited. This component is classified as obsolete, indicating it has reached end-of-life status and is no longer in active production. The obsolete designation necessitates identification of functionally equivalent substitute components to maintain system compatibility and ensure continued availability for design implementations and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BCM5481A2KMLG is determined by the following critical parameters:

• Functional Category: Single-port Gigabit Ethernet PHY interface with RGMII connectivity
• Manufacturer Consistency: Broadcom Limited maintains product line continuity
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status
• Environmental Classification: Moisture sensitivity and handling requirements

The BCM54210EB1KMLG is identified as the manufacturer-recommended substitute. This part maintains the same functional category (Interface, Integrated Circuits) and manufacturer lineage while representing an active production alternative within the Broadcom PHY product portfolio.

Parameter Comparison

Engineering Selection Recommendations

The BCM54210EB1KMLG is the manufacturer-recommended substitute for the obsolete BCM5481A2KMLG. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

The primary distinction is product status: the BCM54210EB1KMLG is in active production, ensuring long-term availability and supply chain continuity. The MSL rating difference (MSL 1 versus MSL 3) reflects standard moisture handling classifications and does not preclude functional substitution for equivalent interface applications.

Selection of the BCM54210EB1KMLG is appropriate for new designs, redesigns of systems using the obsolete BCM5481A2KMLG, and field replacement scenarios where component availability is a critical factor.

Frequently Asked Questions (FAQ)

Q: Can the BCM54210EB1KMLG directly replace the BCM5481A2KMLG in existing designs?

A: Yes. Both components are single-port Gigabit Ethernet PHY interface ICs with RGMII connectivity from Broadcom Limited. The BCM54210EB1KMLG is the manufacturer-designated substitute and maintains functional equivalence for interface applications.

Q: What is the significance of the different MSL ratings?

A: MSL 1 (Unlimited) indicates the BCM5481A2KMLG has no moisture sensitivity restrictions. MSL 3 (168 Hours) for the BCM54210EB1KMLG specifies a 168-hour floor life after moisture exposure. This difference reflects component packaging and material specifications but does not affect functional substitution for standard operating environments.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the BCM5481A2KMLG and BCM54210EB1KMLG are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Why is the BCM5481A2KMLG classified as obsolete?

A: Obsolete status indicates the component has reached end-of-life and is no longer manufactured. The BCM54210EB1KMLG, as an active production component, provides continued access to equivalent Gigabit Ethernet PHY interface functionality.

Q: Are there inventory considerations when selecting a substitute?

A: The BCM54210EB1KMLG is available in active production quantities. The BCM5481A2KMLG, though obsolete, may have limited remaining inventory. For new projects and long-term applications, the BCM54210EB1KMLG is the appropriate selection.
