GD65232PWR Equivalent & Substitute Parts

Part Overview

The GD65232PWR is an active RS232 full transceiver IC manufactured by Texas Instruments, designed for serial communication applications requiring 3 drivers and 5 receivers in a 20-TSSOP surface mount package. This component operates across a wide supply voltage range of ±7.5V to 15V with a data rate of 120Kbps and maintains full duplex communication capability. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications. Equivalent substitute parts are identified based on matching functional specifications, electrical parameters, and physical packaging requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GD65232PWR are identified based on strict equivalence of the following critical parameters:

• RS232 protocol compliance
• 3 drivers and 5 receivers configuration
• Full duplex operation capability
• 120Kbps data rate support
• 20-TSSOP package with 0.173" (4.40mm) width
• Surface mount mounting type
• 500 mV receiver hysteresis
• ROHS3 compliance
• Active product status

The ST75185CTR meets all these core functional and physical requirements, establishing it as a direct substitute within the same electrical and mechanical classification.

Parameter Comparison

Engineering Selection Recommendations

Both the GD65232PWR and ST75185CTR are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The GD65232PWR supports an extended supply voltage range of ±7.5V to 15V and operates across -40°C to 85°C, with MSL rating of 1 (unlimited moisture exposure tolerance). This configuration is suitable for applications requiring wide voltage flexibility and extended temperature operation in demanding environments.

The ST75185CTR operates within a narrower supply voltage range of 4.5V to 5.5V and temperature range of 0°C to 70°C, with MSL rating of 3 (168 hours). This substitute is appropriate for applications with fixed 5V supply requirements and standard commercial temperature operating conditions.

Selection between these parts depends on specific application voltage and temperature requirements. Both parts maintain identical functional specifications for RS232 protocol, driver/receiver configuration, data rate, and physical packaging.

Frequently Asked Questions (FAQ)

Q: Can ST75185CTR replace GD65232PWR in all applications?

A: Substitution is valid only when the application operates within the ST75185CTR's supply voltage range of 4.5V to 5.5V and temperature range of 0°C to 70°C. Applications requiring the extended voltage range (±7.5V to 15V) or temperature range (-40°C to 85°C) of the GD65232PWR cannot use the ST75185CTR as a substitute.

Q: Are the packages physically identical?

A: Both parts use the 20-TSSOP package with identical dimensions of 0.173" (4.40mm width). Pin-to-pin compatibility is established, allowing direct PCB footprint substitution.

Q: What is the difference in moisture sensitivity between these parts?

A: The GD65232PWR carries MSL 1 rating (unlimited moisture exposure), while the ST75185CTR carries MSL 3 rating (168 hours maximum exposure before reflow). This affects storage and handling requirements, with the ST75185CTR requiring more controlled moisture conditions prior to assembly.

Q: Do both parts support the same data rate?

A: Both parts support 120Kbps data rate with identical receiver hysteresis of 500 mV, ensuring equivalent RS232 communication performance.

Q: What are the key differences between these substitutes?

A: The primary differences are supply voltage range, operating temperature range, and moisture sensitivity level. Functional RS232 specifications, driver/receiver configuration, package type, and data rate are identical.
