Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSZ8041TL-S is determined by strict equivalence across the following critical parameters:

• Protocol compatibility: SMII
• Driver/Receiver configuration: 1/1
• Duplex operation: Full
• Supply voltage range: 3.135V ~ 3.465V
• Operating temperature range: 0°C ~ 70°C
• Package specification: 48-TQFP (7x7)
• Mounting technology: Surface Mount
• Regulatory compliance: ROHS3, REACH Unaffected

The KSZ8041FTL-S meets all substitution criteria and shares the same base product number (KSZ8041), confirming functional and electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The KSZ8041FTL-S is the direct substitute for the obsolete KSZ8041TL-S. Both parts maintain identical electrical specifications, protocol support, and physical packaging. The primary distinction is product status: KSZ8041FTL-S is actively manufactured and supported by Microchip Technology, while KSZ8041TL-S is obsolete.

For new designs and ongoing production support, KSZ8041FTL-S is the appropriate selection. Both parts carry equivalent regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected) and identical moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can KSZ8041FTL-S be used as a direct replacement for KSZ8041TL-S?

A: Yes. Both parts are electrically and mechanically equivalent, sharing identical protocol support (SMII), driver/receiver configuration (1/1), supply voltage range (3.135V ~ 3.465V), operating temperature range (0°C ~ 70°C), and 48-TQFP (7x7) package specification.
