Key Parameters

Substitute Part Grouping Explanation

Substitution of the LE88506DVC is determined by the following critical parameters:

• Manufacturer: Microchip Technology (same manufacturer ensures design continuity and support)
• Category: Interface (maintains functional classification)
• Function: Telecom Circuit with PCM interface capability
• Supply Voltage Range: 3.3V ~ 35V (operational voltage compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 3 (168 Hours) (handling and storage requirements)

The LE9632RQC is identified as a manufacturer-recommended substitute. While it employs a different package format (53QFN versus 64-TQFP), it maintains functional equivalence through identical manufacturer origin, interface type, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LE9632RQC is the manufacturer-recommended substitute for the obsolete LE88506DVC. Selection of this substitute is supported by:

• Active Product Status: The LE9632RQC maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both components meet ROHS3 compliance requirements, satisfying environmental and regulatory standards.
• Identical Certifications: Matching RoHS status and moisture sensitivity levels ensure equivalent handling, storage, and operational reliability.
• Manufacturer Continuity: Both components originate from Microchip Technology, providing consistent design support and technical documentation.

Package format transition from 64-TQFP to 53QFN requires PCB layout modification and component placement adjustment. This substitution is appropriate for new designs and system redesigns where layout flexibility exists.

Frequently Asked Questions (FAQ)

Q: Can the LE9632RQC be used as a direct pin-for-pin replacement for the LE88506DVC?

A: No. The LE9632RQC uses a 53QFN package format while the LE88506DVC uses 64-TQFP. Pin assignments and physical dimensions differ, requiring PCB redesign and component placement modification.

Q: What is the primary reason for substituting the LE88506DVC?

A: The LE88506DVC is classified as obsolete. The LE9632RQC is the manufacturer-recommended active substitute, ensuring continued availability and support.

Q: Are there compliance differences between these components?

A: No. Both components maintain identical RoHS3 compliance status and moisture sensitivity levels (MSL 3, 168 Hours), ensuring equivalent regulatory and environmental performance.

Q: What design considerations apply when transitioning from LE88506DVC to LE9632RQC?

A: PCB layout must be redesigned to accommodate the 53QFN package format. Component placement, trace routing, and thermal management may require adjustment based on the new package geometry.

Q: Is the LE9632RQC suitable for existing systems using the LE88506DVC?

A: Substitution in existing systems requires PCB modification. For new designs or system redesigns, the LE9632RQC is the appropriate selection.
