Substitute Part Grouping Explanation

The VSC8552XKS-02 qualifies as a direct substitute for the VSC8552XKS-01 based on the following matching parameters:

• Identical manufacturer: Microchip Technology
• Identical functional category: Telecom Interface / Ethernet
• Identical package specification: 256-PBGA (17x17)
• Identical electrical supply voltage: 1V
• Identical number of circuits: 1
• Identical mounting type: Surface Mount
• Identical RoHS compliance: ROHS3 Compliant
• Identical moisture sensitivity level: MSL 4 (72 Hours)
• Identical REACH status: REACH Unaffected

The primary distinction is product status: VSC8552XKS-01 is obsolete, while VSC8552XKS-02 is active. The VSC8552XKS-02 is supplied in Tray packaging, compared to the original part's unspecified packaging format.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can VSC8552XKS-02 be used as a direct replacement for VSC8552XKS-01?

A: Yes. Both parts share identical electrical specifications (1V supply), package configuration (256-PBGA 17x17), and functional characteristics (Ethernet telecom interface). The VSC8552XKS-02 is the active equivalent.

Q: What is the difference between VSC8552XKS-01 and VSC8552XKS-02?

A: The primary difference is product lifecycle status. VSC8552XKS-01 is obsolete; VSC8552XKS-02 is active. Packaging format differs (unspecified vs. Tray), but all electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns with the 256-PBGA (17x17) package?

A: No. Both parts use the identical 256-BGA package specification. PCB layout, solder reflow profiles, and thermal management requirements remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both VSC8552XKS-01 and VSC8552XKS-02 are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 4 (72 Hours).

Q: Which part should be specified for new designs?

A: VSC8552XKS-02 should be specified for all new designs. It is the active product with ongoing manufacturer support.
