Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent part selection is based on the following strictly matched parameters from the Telecom Interface IC category: Manufacturer, Function, Interface type, Mounting Type, RoHS and REACH compliance, MSL rating, and regulatory status (ECCN/HTSUS). No assumptions are made outside the explicit values provided for package type, number of circuits, or supply voltage.

Parameter Comparison

Engineering Selection Recommendations

The LE9622RQCT is listed as a potential substitute based on its matching RoHS3 compliance, REACH status, Moisture Sensitivity Level (MSL 3, 168 hours), and EAR99 ECCN designation. Both parts are produced by Microchip Technology and belong to the Interface category, ensuring uniformity in manufacturer standards and regulatory compliance. Substitution is justified by the main part’s obsolete status and the continued availability of the LE9622RQCT as an Active product.

Frequently Asked Questions (FAQ)

Q: What parameters are used to determine equivalent or substitute Interface ICs for LE88266DLCT?
A: Substitution is determined strictly by manufacturer, product category, compliance statuses (RoHS, REACH), MSL rating, mounting type, and function where described.

Q: Are there packaging differences between LE88266DLCT and LE9622RQCT that must be considered?
A: Yes. LE88266DLCT is available in 80-LQFP / 80-eLQFP, while LE9622RQCT utilizes a 53-QFN (7x7) package. Selection should account for PCB footprint compatibility.

Q: Does the number of integrated circuits differ between main and substitute parts?
A: The main part provides 2 circuits, while the substitute provides 1 circuit, as explicitly provided in the parameters.

Q: Is compliance status identical for both component options?
A: Both are ROHS3 Compliant, REACH Unaffected, assigned MSL 3 (168 Hours), and have ECCN EAR99.

Q: Are both parts suitable for use in surface mount applications?
A: Yes, both are designed for surface mounting.

Q: How does product status affect substitute selection?
A: LE88266DLCT is Obsolete, and LE9622RQCT is Active, supporting continuity in procurement and inventory.

Q: Can package change influence thermal or mechanical characteristics?
A: Only package/case and mounting method parameters are provided. Footprint compatibility should be accounted for as indicated by package descriptions.
