TRS202IPW RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The TRS202IPW is a 2/2 full-duplex RS232 transceiver manufactured by Texas Instruments in a 16-TSSOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring RS232 interface functionality. The part operates across a 4.5V to 5.5V supply range with a 120 kbps data rate and 500 mV receiver hysteresis, suitable for legacy serial communication applications.

Substitute Part Grouping Explanation

Substitution for the TRS202IPW is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Protocol: RS232
Number of Drivers/Receivers: 2/2
Duplex: Full
Package / Case: 16-TSSOP (0.173", 4.40mm Width)
Mounting Type: Surface Mount
Voltage - Supply: 4.5V ~ 5.5V (minimum requirement)
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Parameter Variations:

Receiver Hysteresis: 500 mV (primary), 650 mV (acceptable for ADM202 series), 300 mV (acceptable for SP3232 series)
Data Rate: 120 kbps (primary), 230 kbps (acceptable for ADM202 series), 250 kbps (acceptable for SP3232 series)
Operating Temperature: -40°C ~ 85°C (primary), 0°C ~ 70°C (acceptable for commercial-grade variants)
Product Status: Active status preferred over obsolete

Substitute parts are grouped into three categories: parametric equivalents (identical electrical specifications), direct manufacturer alternatives (same base product line with different packaging), and manufacturer-recommended alternatives (enhanced specifications within compatible parameters).

Engineering Selection Recommendations

For Extended Temperature Range Applications (-40°C ~ 85°C):

Select MAX202EEUE+T or ADM202EARUZ-REEL series. MAX202EEUE+T maintains identical electrical specifications (500 mV hysteresis, 120 kbps data rate) with active product status and tape & reel packaging suitable for automated assembly. ADM202EARUZ-REEL offers enhanced data rate capability (230 kbps) and higher receiver hysteresis (650 mV) while maintaining the full temperature range, providing performance headroom for legacy system upgrades.

For Commercial Temperature Range Applications (0°C ~ 70°C):

MAX202ECUE+T is the preferred selection, offering the highest inventory availability (19524 pcs) with active product status, identical electrical specifications to the original TRS202IPW, and tape & reel packaging. This part is optimized for high-volume production environments.

For Enhanced Performance with Wider Supply Voltage Range:

SP3232EBCY-L/TR from MaxLinear operates across 3V to 5.5V supply range with superior data rate (250 kbps) and lower receiver hysteresis (300 mV). This part is suitable for applications requiring extended supply voltage tolerance, though operating temperature is limited to 0°C ~ 70°C.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and EAR99 export classification, matching the original TRS202IPW specifications. Selection should prioritize active product status parts to ensure long-term availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can MAX202ECUE+T directly replace TRS202IPW in all applications?

A: MAX202ECUE+T is electrically equivalent with identical receiver hysteresis (500 mV) and data rate (120 kbps). The operating temperature range differs: MAX202ECUE+T operates 0°C ~ 70°C versus TRS202IPW's -40°C ~ 85°C. For applications requiring extended temperature operation, use MAX202EEUE+T or ADM202EARUZ-REEL instead.

Q: What is the difference between ADM202EARUZ and ADM202EARUZ-REEL?

A: Both parts are electrically identical with 650 mV receiver hysteresis and 230 kbps data rate. ADM202EARUZ is supplied in tube packaging, while ADM202EARUZ-REEL is supplied in tape & reel format. ADM202EARUZ-REEL7 is supplied in cut tape with Digi-Reel packaging. Selection depends on assembly process requirements.

Q: Is SP3232EBCY-L/TR compatible with TRS202IPW designs?

A: SP3232EBCY-L/TR is mechanically and electrically compatible within the 16-TSSOP package and RS232 protocol. However, it operates at 0°C ~ 70°C (not -40°C ~ 85°C), has lower receiver hysteresis (300 mV versus 500 mV), and higher data rate (250 kbps versus 120 kbps). Use only in applications where these parameter differences are acceptable.

Q: Why is TRS202IPW marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active alternatives from Analog Devices Inc./Maxim Integrated and MaxLinear provide equivalent or enhanced functionality with ongoing manufacturing support and availability.

Q: What packaging format should I select for high-volume production?

A: Tape & reel (TR) packaging is standard for automated pick-and-place assembly. MAX202ECUE+T offers the largest inventory (19524 pcs) in tape & reel format. Cut tape with Digi-Reel packaging (ADM202EARUZ-REEL7, SP3232EBCY-L/TR) provides flexibility for mixed-volume production runs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity, matching the original TRS202IPW specifications.
