TRS202EIPWR RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The TRS202EIPWR is a full-duplex RS232 transceiver manufactured by Texas Instruments, designed for serial communication applications requiring 2 drivers and 2 receivers in a 16-TSSOP surface mount package. The device operates across a 4.5V to 5.5V supply range with a maximum data rate of 120Kbps and is rated for -40°C to 85°C operating temperatures. This part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when design requirements permit relaxed electrical specifications, extended supply voltage ranges, higher data rates, or alternative temperature ratings while maintaining the same functional protocol, package form factor, and core transceiver architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TRS202EIPWR is determined by the following criteria:

Mandatory Compatibility Parameters:

• Protocol: RS232
• Drivers/Receivers: 2/2 configuration
• Duplex: Full
• Package: 16-TSSOP
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 or equivalent

Allowable Variation Parameters:

• Voltage Supply: Extended ranges (3V ~ 5.5V) are acceptable if the design operates within the original 4.5V ~ 5.5V window
• Data Rate: Higher rates (235Kbps, 250Kbps, 1Mbps) are acceptable for applications not requiring the original 120Kbps specification
• Operating Temperature: Extended ranges (-40°C ~ 85°C or 0°C ~ 70°C) are acceptable based on application requirements
• Receiver Hysteresis: Variations (300 mV vs 500 mV) are acceptable within RS232 specification tolerances

Substitute parts are grouped by manufacturer and performance tier, with Texas Instruments parametric equivalents listed separately from MaxLinear manufacturer-recommended alternatives.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent: MAX202IPWR is a direct parametric equivalent to TRS202EIPWR, offering identical electrical specifications and operating ranges. Both devices are manufactured by Texas Instruments and maintain the same 120Kbps data rate, 4.5V to 5.5V supply voltage, and -40°C to 85°C temperature rating. Selection between these two parts depends on packaging availability (Tape & Reel vs. Cut Tape & Digi-Reel) and inventory status.

MaxLinear SP3232 Series Alternatives: The SP3232 family from MaxLinear provides functional substitutes with enhanced performance characteristics. These parts maintain full RS232 protocol compliance, 2/2 driver/receiver configuration, and 16-TSSOP packaging. Key differences include:

• SP3232EBEY-L/TR and SP3232EEY-L/TR support the full -40°C to 85°C temperature range matching the original specification, with data rates of 250Kbps and 235Kbps respectively
• SP3232EBCY-L/TR and SP3232ECY-L/TR operate within 0°C to 70°C temperature range, suitable for commercial-grade applications
• SP3232EUCY-L/TR and SP3232EUEY-L/TR offer the highest data rate performance at 1Mbps, with EUEY-L/TR supporting the full -40°C to 85°C industrial temperature range

All MaxLinear alternatives feature extended supply voltage range (3V to 5.5V), providing greater flexibility in power supply design. ROHS3 compliance is maintained across the SP3232EBEY, EBCY, ECY, and EEY variants.

Selection criteria: Choose SP3232EBEY-L/TR or SP3232EEY-L/TR for direct temperature-range compatibility with industrial applications. Choose SP3232EUEY-L/TR when higher data rate performance (1Mbps) and extended temperature range are required. Choose SP3232EBCY-L/TR or SP3232ECY-L/TR for commercial-grade applications with relaxed temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX202IPWR be used as a direct replacement for TRS202EIPWR? A: Yes. MAX202IPWR is a parametric equivalent with identical electrical specifications, operating voltage range (4.5V to 5.5V), data rate (120Kbps), and temperature rating (-40°C to 85°C). The only difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel).

Q: What are the key differences between TRS202EIPWR and SP3232 series parts? A: SP3232 series parts offer higher data rates (235Kbps to 1Mbps vs. 120Kbps), extended supply voltage range (3V to 5.5V vs. 4.5V to 5.5V), and lower receiver hysteresis (300 mV vs. 500 mV). All maintain the same RS232 protocol, 2/2 configuration, and 16-TSSOP package. Temperature ratings vary by specific variant.

Q: Which substitute part should I select for industrial temperature range applications? A: For industrial applications requiring -40°C to 85°C operation, select either SP3232EBEY-L/TR (250Kbps data rate) or SP3232EUEY-L/TR (1Mbps data rate). Both support the full temperature range and are ROHS3 compliant.

Q: Are all substitute parts available in the same 16-TSSOP package? A: Yes. All listed substitute parts use the 16-TSSOP (0.173", 4.40mm Width) surface mount package, ensuring mechanical and electrical compatibility with TRS202EIPWR PCB layouts.

Q: What is the impact of different receiver hysteresis values? A: TRS202EIPWR specifies 500 mV receiver hysteresis, while SP3232 series parts specify 300 mV. Both values comply with RS232 specifications. Lower hysteresis (300 mV) provides improved noise immunity in certain applications but does not affect basic functional compatibility.

Q: Can SP3232 parts operate at the original 4.5V to 5.5V supply range? A: Yes. SP3232 series parts support 3V to 5.5V supply voltage range, which encompasses the original 4.5V to 5.5V specification. They are fully compatible with existing power supply designs.

Q: What is the difference between SP3232EBEY-L/TR and SP3232EUEY-L/TR? A: Both support -40°C to 85°C temperature range and 3V to 5.5V supply voltage. The primary difference is data rate: SP3232EBEY-L/TR operates at 250Kbps, while SP3232EUEY-L/TR operates at 1Mbps. Select based on required communication speed.
