Substitute Part Grouping Explanation

Substitution of the LE89116QVC is based on the following critical parameters:

• Manufacturer: Microchip Technology (maintained for design continuity and support)
• Category: Interface (functional classification)
• Interface Type: PCM (primary functional requirement)
• Number of Circuits: 1 (functional equivalence)
• Mounting Type: Surface Mount (assembly compatibility)
• Compliance Standards: RoHS3 Compliant and REACH Unaffected status (regulatory alignment)

The substitute part LE9643AQC meets these core substitution criteria while offering active product status, ensuring long-term availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The LE9643AQC is the manufacturer-recommended substitute for the obsolete LE89116QVC. Both components maintain identical functional parameters for PCM interface applications and share equivalent compliance certifications (RoHS3 Compliant, REACH Unaffected). The primary distinction is the package format transition from 48-LQFP to 36QFN, which requires PCB layout and assembly process evaluation. The active product status of the LE9643AQC ensures continued manufacturer support, availability, and compliance with current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: What are the key functional differences between LE89116QVC and LE9643AQC?

A: Both components are single-circuit PCM interface ICs from Microchip Technology. The primary difference is the package format: LE89116QVC uses 48-LQFP while LE9643AQC uses 36QFN. Functional parameters for PCM interface operation remain equivalent.

Q: Does the package change from 48-LQFP to 36QFN affect compatibility?

A: Package format changes require PCB layout redesign and assembly process validation. Pin count and pinout must be verified against application schematics before implementation.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both LE89116QVC and LE9643AQC are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Q: Why is LE89116QVC classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The LE9643AQC is the active alternative for new designs and ongoing support.

Q: What is the Moisture Sensitivity Level significance?

A: MSL 3 (168 Hours) for LE89116QVC indicates storage and handling requirements. Verify MSL specifications for LE9643AQC in detailed datasheets for equivalent moisture management protocols.
