MAX202IPWRE4 Equivalent & Substitute Parts

Part Overview

The MAX202IPWRE4 is a 2/2 full-duplex RS232 transceiver manufactured by Texas Instruments, housed in a 16-TSSOP surface mount package. This interface IC operates across a 4.5V to 5.5V supply range with a 120 kbps data rate and 500 mV receiver hysteresis. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements. Substitute parts must maintain compatibility with the electrical specifications, mechanical packaging, and operational parameters of the original component.

Substitute Part Grouping Explanation

Substitution of the MAX202IPWRE4 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Protocol: RS232
Drivers/Receivers: 2/2 configuration
Duplex: Full
Package/Case: 16-TSSOP (0.173", 4.40mm Width)
Mounting Type: Surface Mount
Voltage Supply Range: Must encompass or match 4.5V ~ 5.5V
RoHS Compliance: ROHS3 Compliant

Allowable Variations:

Data Rate: Substitute parts may exceed 120 kbps (backward compatible)
Receiver Hysteresis: Substitute parts may differ from 500 mV if within RS232 specification tolerances
Operating Temperature: Substitute parts with narrower ranges (-40°C ~ 85°C or 0°C ~ 70°C) are acceptable for applications within those ranges
Manufacturer: Alternative manufacturers permitted if all electrical and mechanical parameters align

Substitute parts are grouped into two categories: parametric equivalents (identical specifications) and functional alternatives (enhanced performance within compatible parameters).

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitution):

MAX202IPWR is the direct parametric equivalent to MAX202IPWRE4, differing only in packaging format (Cut Tape & Digi-Reel versus the original packaging). This part maintains identical electrical specifications and operating temperature range, with active product status and ROHS3 compliance. Selection of MAX202IPWR is appropriate for applications requiring no design modification.

MAX202EEUE+ and MAX202CUE+ are functionally equivalent MAX202 variants. MAX202EEUE+ maintains the full -40°C ~ 85°C operating range, while MAX202CUE+ operates within 0°C ~ 70°C. Both are ROHS3 compliant and active products. MAX202CUE+ is suitable only for applications within the narrower temperature specification.

Enhanced Performance Alternatives:

ADM202EARUZ-REEL and ADM202EARUZ-REEL7 provide increased data rate (230 kbps) and higher receiver hysteresis (650 mV) while maintaining the 4.5V ~ 5.5V supply range and -40°C ~ 85°C operating temperature. These parts are ROHS3 compliant and active. The ADM202 series is suitable for applications requiring higher data throughput.

SP3232 series parts (SP3232EBEY-L/TR, SP3232EBCY-L/TR, SP3232ECY-L/TR, SP3232EEY-L/TR) offer extended supply voltage range (3V ~ 5.5V), higher data rates (235–250 kbps), and lower receiver hysteresis (300 mV). All are ROHS3 compliant and active. SP3232EBEY-L/TR and SP3232EEY-L/TR support the full -40°C ~ 85°C temperature range. SP3232 variants are suitable for low-voltage applications and high-speed RS232 communication.

Product Status Consideration:

All substitute parts listed maintain active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The original MAX202IPWRE4 is discontinued; selection of any active substitute ensures continued supply chain viability.
