TRS202ECPW RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The TRS202ECPW 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 new designs and ongoing production requirements. The device 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 transceiver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TRS202ECPW are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• 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

Substitute parts are classified into two categories:

MFR Recommended (Texas Instruments): Parts that maintain the same manufacturer lineage with active product status and extended operating temperature ranges.

MFR Recommended (MaxLinear, Inc.): Parts that meet all core electrical and mechanical parameters with active product status, offering enhanced performance characteristics such as higher data rates and extended temperature ranges.

Parametric Equivalent (Texas Instruments): Parts that match the original specifications but maintain obsolete status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): TRS202EIPWR is the primary substitute from Texas Instruments. It maintains identical electrical specifications to the TRS202ECPW while offering active product status and extended operating temperature range (-40°C to 85°C). This part is available in Tape & Reel packaging with 15,704 units in stock.

For Active Product Status with Enhanced Performance: The SP3232 series from MaxLinear, Inc. provides active product status across all variants. All SP3232 parts maintain the 2/2 full-duplex RS232 transceiver configuration and 16-TSSOP package. The series offers multiple data rate options (235 kbps to 1 Mbps) and extended supply voltage range (3V to 5.5V), providing design flexibility for both legacy and modern applications. All variants are ROHS3 compliant with MSL 1 rating.

For Temperature-Extended Applications: SP3232EBEY-L/TR, SP3232EEY-L/TR, SP3232EHEY-L/TR, and SP3232EUCY-L/TR support -40°C to 85°C operating temperature range, suitable for industrial and automotive environments.

For Packaging Considerations: Tube packaging is available in SP3232ECY-L. Cut Tape & Digi-Reel packaging is available in SP3232EBCY-L/TR, SP3232EBEY-L/TR, SP3232ECY-L/TR, and SP3232EEY-L/TR. Tape & Reel packaging is available in TRS202EIPWR, SP3232EHCY-L/TR, SP3232EHEY-L/TR, and SP3232EUCY-L/TR.

Frequently Asked Questions (FAQ)

Q: Can SP3232 series parts directly replace TRS202ECPW? A: Yes. All SP3232 variants maintain the required 2/2 full-duplex RS232 transceiver configuration, 16-TSSOP package, and surface mount mounting type. The extended supply voltage range (3V to 5.5V) encompasses the original 4.5V to 5.5V requirement. Higher data rates in SP3232 variants do not affect backward compatibility with 120 kbps applications.

Q: What is the difference between SP3232EBCY-L/TR and SP3232EBEY-L/TR? A: Both parts are identical except for operating temperature range. SP3232EBCY-L/TR operates 0°C to 70°C, while SP3232EBEY-L/TR operates -40°C to 85°C. Both support 250 kbps data rate and are available in Cut Tape & Digi-Reel packaging.

Q: Why do SP3232 parts have lower receiver hysteresis (300 mV) compared to TRS202ECPW (500 mV)? A: Receiver hysteresis is a specified parameter provided in the input data. Both values fall within acceptable RS232 transceiver specifications and do not prevent functional substitution in standard RS232 applications.

Q: Which substitute part has the highest data rate? A: SP3232EUCY-L/TR supports 1 Mbps data rate, the highest among all listed substitutes. This part is suitable for applications requiring higher communication speeds while maintaining full RS232 protocol compliance.

Q: Is TRS202EIPWR available in the same packaging as TRS202ECPW? A: No. TRS202ECPW is supplied in Tube packaging, while TRS202EIPWR is supplied in Tape & Reel (TR) packaging. Both use the same 16-TSSOP case, so component-level compatibility is maintained; only supply packaging differs.

Q: Are all substitute parts ROHS3 compliant? A: All listed substitute parts are ROHS3 compliant or RoHS compliant, meeting environmental regulatory requirements equivalent to or exceeding the original TRS202ECPW specification.
