Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete KS8842-32MQL is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Identical manufacturer (Microchip Technology)
• Identical base product number (KS8842 series)
• Identical package configuration (128-BFQFP / 128-PQFP 14x20)
• Identical RoHS and REACH compliance status
• Identical MSL rating (3, 168 Hours)
• Identical ECCN and HTSUS classifications

The KSZ8842-32MQL meets all substitution criteria as a direct equivalent. Both parts share the same physical footprint, electrical interface requirements, and regulatory compliance framework, enabling pin-for-pin and form-factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

The KSZ8842-32MQL is the direct substitute for the obsolete KS8842-32MQL. Selection is based on the following engineering factors:

Product Status: The KSZ8842-32MQL maintains active product status with Microchip Technology, ensuring continued availability and manufacturing support. The original KS8842-32MQL is obsolete and no longer manufactured.

Compliance Alignment: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL ratings. This ensures regulatory and environmental compliance requirements are preserved across substitution.

Physical Compatibility: Identical package specifications (128-BFQFP, 128-PQFP 14x20) confirm direct PCB footprint compatibility without layout modifications.

Supply Chain Continuity: The substitute part is available in production quantities, supporting both new designs and legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can KSZ8842-32MQL be used as a direct replacement for KS8842-32MQL?

A: Yes. Both parts share identical package configurations (128-PQFP 14x20), RoHS compliance status, MSL ratings, and regulatory classifications. The parts are pin-for-pin compatible and require no PCB modifications.

Q: What is the primary reason for substitution?

A: The KS8842-32MQL is classified as obsolete. The KSZ8842-32MQL is the active equivalent manufactured by the same supplier, ensuring continued component availability.

Q: Are there differences in electrical specifications between these parts?

A: The substitute part specifies operating voltage (3.1V ~ 3.5V), supply current (122mA), and operating temperature range (0°C ~ 70°C). These parameters were not provided for the original part. Verify these specifications align with your application requirements.

Q: Does substitution require PCB redesign?

A: No. Both parts use the 128-BFQFP package with identical 14x20mm dimensions. No layout or footprint modifications are necessary.

Q: Are compliance certifications maintained?

A: Yes. Both parts maintain ROHS3 compliance, REACH unaffected status, identical MSL ratings (3, 168 Hours), and matching ECCN and HTSUS classifications.

Q: What is the packaging format for the substitute part?

A: The KSZ8842-32MQL is supplied in Tray packaging, consistent with standard handling and storage requirements for 128-pin PQFP components.
