LE24163LBXA-SH Equivalent & Substitute Parts

Part Overview

The LE24163LBXA-SH is a 16Kbit EEPROM memory IC manufactured by onsemi, featuring I2C interface with 400 kHz clock frequency and 900 ns access time in a 5-WLCSP package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part operates across a supply voltage range of 1.7V to 3.6V and supports industrial temperature ranges from -40°C to 85°C.

Substitute Part Grouping Explanation

Substitution eligibility for the LE24163LBXA-SH is determined by strict equivalence across the following critical parameters:

Memory capacity: 16Kbit (2K x 8 organization)
Interface protocol: I2C at 400 kHz
Electrical specifications: 1.7V to 3.6V supply voltage
Timing characteristics: 900 ns access time, 5ms write cycle time
Temperature range: -40°C to 85°C operation
Form factor: Surface mount, ultra-compact ball grid array packages

The BRCB016GWL-3UE2 from Rohm Semiconductor meets all substitution criteria. Both parts share identical memory specifications, interface characteristics, electrical ratings, and thermal operating ranges. The primary distinction lies in package geometry (5-UCSP50L1 versus 5-WLCSP) and product lifecycle status.

Engineering Selection Recommendations

The BRCB016GWL-3UE2 serves as a direct functional substitute for the obsolete LE24163LBXA-SH based on the following engineering criteria:

Electrical and functional equivalence is confirmed across all specified parameters: memory capacity, interface protocol, supply voltage range, operating temperature, and timing characteristics. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The primary consideration for implementation is package geometry. The BRCB016GWL-3UE2 utilizes a 5-UCSP50L1 package (1.1x1.15mm) compared to the LE24163LBXA-SH 5-WLCSP package (1.20x0.80mm). PCB layout modifications may be required to accommodate the different ball grid array footprint. The BRCB016GWL-3UE2 maintains active product status with confirmed inventory availability, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the BRCB016GWL-3UE2 directly replace the LE24163LBXA-SH without design changes?

A: Functional replacement is supported. However, package geometry differs between the two components. PCB footprint redesign is necessary to accommodate the 5-UCSP50L1 package dimensions. Electrical and protocol compatibility is confirmed across all specified parameters.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on equivalence in memory capacity (16Kbit), memory organization (2K x 8), interface type (I2C 400 kHz), supply voltage range (1.7V to 3.6V), operating temperature (-40°C to 85°C), and write cycle time (5ms). Both components meet these criteria.

Q: Why is the LE24163LBXA-SH listed as obsolete?

A: The LE24163LBXA-SH has reached end-of-life status with onsemi. The BRCB016GWL-3UE2 from Rohm Semiconductor is an active product offering equivalent functionality for new designs and legacy system support.

Q: Are there compliance differences between these components?

A: Both components are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent, supporting use in applications with identical environmental and safety requirements.

Q: What is the primary design consideration when switching to the BRCB016GWL-3UE2?

A: Package footprint compatibility is the primary design consideration. The 5-UCSP50L1 package requires PCB layout modifications compared to the 5-WLCSP package. All electrical and functional parameters remain equivalent.
