KSZ8841-PMQL Equivalent & Substitute Parts

Part Overview

The KSZ8841-PMQL is an Ethernet MAC Controller designed for 10/100 Base-T/TX PHY applications with PCI interface connectivity. This integrated circuit operates as a 32-bit controller in a 128-PQFP package and is actively supported by Microchip Technology. The device is ROHS3 compliant and maintains active product status, making it suitable for current production designs. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to alternative inventory sources when the primary part number becomes unavailable.

Substitute Part Grouping Explanation

Substitute parts for the KSZ8841-PMQL are identified based on strict parametric equivalence across the following critical criteria:

  • Identical Ethernet MAC Controller function with 10/100 Base-T/TX PHY support
  • PCI interface compatibility
  • Matching 128-BFQFP package configuration (14x20mm)
  • Identical voltage supply range (3.1V ~ 4.6V)
  • Identical current supply specification (100mA)
  • Matching operating temperature range (0°C ~ 70°C)
  • Equivalent RoHS and environmental compliance status
  • Same base product family (KSZ8841 series)

The KSZ8841-32MQL meets all these parameters and qualifies as a parametric equivalent substitute. Both parts share the same base product number (KSZ8841) and are manufactured by Microchip Technology with identical electrical and mechanical specifications.

Engineering Selection Recommendations

Both the KSZ8841-PMQL and KSZ8841-32MQL are active products from Microchip Technology with identical electrical specifications, package configurations, and compliance certifications. Selection between these parts should be based on availability and supply chain requirements rather than technical differentiation. Both parts maintain ROHS3 compliance and equivalent moisture sensitivity ratings, ensuring compatibility with standard PCB assembly and storage protocols. The KSZ8841-32MQL offers significantly higher inventory availability (1,000,099 units) compared to the KSZ8841-PMQL (17,300 units), making it a viable alternative for high-volume production requirements or extended lead-time mitigation.

Frequently Asked Questions (FAQ)

Q: Can the KSZ8841-32MQL be used as a direct replacement for the KSZ8841-PMQL?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, PCI interface configuration, 128-BFQFP package dimensions, voltage supply range, current requirements, and operating temperature range. No circuit modifications are required for substitution.

Q: Are there any differences in RoHS or environmental compliance between these parts?

A: No. Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level 3 ratings (168 hours). Environmental handling and storage requirements are equivalent.

Q: What determines whether a part qualifies as a substitute for the KSZ8841-PMQL?

A: Substitution is based on matching the following parameters: Ethernet MAC Controller function, 10/100 Base-T/TX PHY support, PCI interface, 128-BFQFP package, 3.1V–4.6V supply voltage, 100mA current specification, 0°C–70°C operating temperature, and equivalent compliance certifications.

Q: Does package marking or date code differ between these parts?

A: Package type and dimensions are identical (128-BFQFP, 14x20mm). Specific date codes and markings may vary based on manufacturing lot, but this does not affect electrical or mechanical compatibility.

Q: Which part should be selected for new designs?

A: Both parts are suitable for new designs. Selection should prioritize availability and supply chain stability. The KSZ8841-32MQL offers higher inventory levels and may provide better long-term supply assurance.
