TRS202CPWRG4 Equivalent & Substitute Parts

Part Overview

The TRS202CPWRG4 is a 2/2 full-duplex RS232 transceiver manufactured by Texas Instruments in a 16-TSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The TRS202CPWRG4 operates within a 4.5V to 5.5V supply voltage range with a 120 kbps data rate and 500 mV receiver hysteresis, suitable for legacy RS232 communication applications requiring full-duplex operation with two drivers and two receivers.

Substitute Part Grouping Explanation

Substitution of the TRS202CPWRG4 is determined by strict equivalence in the following 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)

Substitute parts are grouped into three categories based on operational characteristics and product status:

Parametric Equivalents maintain identical electrical specifications including 120 kbps data rate and 500 mV receiver hysteresis, with identical operating temperature range (0°C ~ 70°C).

Direct Manufacturers provide active production alternatives with identical core specifications but may differ in packaging format (Tube vs. Cut Tape & Digi-Reel).

Upgrade Options offer extended operating temperature ranges (-40°C ~ 85°C) or enhanced data rates (230 kbps or 250 kbps) while maintaining full compatibility with the 16-TSSOP package and RS232 2/2 full-duplex configuration.

Engineering Selection Recommendations

For direct replacement of the obsolete TRS202CPWRG4 in active production designs, MAX202ECUE+ or MAX202CUE+ are recommended as they maintain identical electrical specifications and are currently in active production status with ROHS3 compliance and MSL 1 rating.

For designs requiring extended operating temperature range (-40°C ~ 85°C), MAX202EEUE+ or MAX202EEUE+T provide identical core functionality with expanded thermal performance while maintaining the same 16-TSSOP package footprint.

For applications where higher data rates are acceptable, ADM202EARUZ, ADM202EARUZ-REEL, or ADM202EARUZ-REEL7 offer 230 kbps operation with extended temperature range and active production status. These parts maintain full compatibility with the 16-TSSOP package and RS232 2/2 full-duplex configuration.

For designs requiring the lowest supply voltage floor (3V minimum), SP3232EBCY-L/TR or SP3232EBEY-L/TR provide 250 kbps data rate capability with extended voltage range and active production status. SP3232EBEY-L/TR additionally supports the extended temperature range (-40°C ~ 85°C).

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and identical 16-TSSOP surface mount package specifications.

Frequently Asked Questions (FAQ)

Q: Can MAX202EEUE+ directly replace TRS202CPWRG4 in existing designs?

A: Yes. MAX202EEUE+ maintains identical electrical specifications (120 kbps data rate, 500 mV receiver hysteresis, 4.5V ~ 5.5V supply) and 16-TSSOP package footprint. The extended operating temperature range (-40°C ~ 85°C) provides additional thermal margin without affecting compatibility.

Q: What is the difference between MAX202EEUE+ and MAX202EEUE+T?

A: Both parts are electrically identical. MAX202EEUE+T is supplied in Tape & Reel packaging format, while MAX202EEUE+ is supplied in Tube packaging. Selection depends on procurement and assembly requirements.

Q: Can ADM202EARUZ be used as a substitute despite higher data rate and receiver hysteresis specifications?

A: ADM202EARUZ is electrically compatible for RS232 2/2 full-duplex applications in the 16-TSSOP package. The 230 kbps data rate and 650 mV receiver hysteresis represent enhanced performance characteristics. Compatibility depends on application-specific requirements for data rate and noise margin.

Q: What is the advantage of SP3232EBEY-L/TR over other substitutes?

A: SP3232EBEY-L/TR supports a lower minimum supply voltage (3V vs. 4.5V), higher data rate (250 kbps), and extended operating temperature range (-40°C ~ 85°C). It is suitable for applications requiring lower power operation or wider thermal performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original TRS202CPWRG4 specifications.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tube, Tape & Reel, or Cut Tape & Digi-Reel) does not affect electrical performance. Selection is based on procurement volume, assembly equipment compatibility, and inventory management requirements.
