Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility is determined by matching manufacturer, function, interface type, number of circuits, supply voltage, mounting type, package, RoHS compliance, and product status. The substitute part LE9541CUQCT has been grouped for review because it is a Subscriber Line Interface Concept (SLIC), supports 1 circuit, operates at the same supply voltage of 3.3V, utilizes surface mount technology, and is ROHS3 compliant. Differences in interface (serial vs parallel) and package type (40-QFN vs 28-PLCC) are noted, based only on supplied input parameters.

Parameter Comparison

Engineering Selection Recommendations

LE9500BBJCT is obsolete; LE9541CUQCT is active. Both are ROHS3 compliant. Both are manufactured by Microchip Technology and fall under the telecom interface IC category. Packaging and Moisture Sensitivity Level differ: LE9500BBJCT is in 28-PLCC with MSL 1 (Unlimited), while LE9541CUQCT is in 40-QFN with MSL 3 (168 Hours). The interface type differs (parallel for LE9500BBJCT, serial for LE9541CUQCT). Selection should adhere to the listed compliance certifications and product status.

Frequently Asked Questions (FAQ)

Q: What parameters are used to determine a suitable substitute for LE9500BBJCT?
A: Manufacturer, function, interface type, supply voltage, circuit number, mounting type, package, RoHS status, moisture sensitivity level, and product status are the considered substitution parameters.

Q: Is LE9541CUQCT directly compatible with LE9500BBJCT in all designs?
