GD75232PWRG4 Equivalent & Substitute Parts

Part Overview

The GD75232PWRG4 is a full-duplex RS232 transceiver IC with 3 drivers and 5 receivers, manufactured by Texas Instruments in a 20-TSSOP surface mount package. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The device operates across a wide supply voltage range (5V, ±7.5V ~ 15V) and supports data rates up to 120 Kbps with 500 mV receiver hysteresis.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GD75232PWRG4 is determined by the following critical parameters:

• Protocol Compatibility: RS232 full-duplex transceiver functionality
• Driver/Receiver Configuration: 3 drivers and 5 receivers
• Package Type: 20-TSSOP surface mount package with identical physical dimensions
• Electrical Specifications: Data rate (120 Kbps), receiver hysteresis (500 mV), and operating temperature range (0°C ~ 70°C)
• Supply Voltage Range: Compatibility with the specified voltage operating window
• Compliance Standards: RoHS3 compliance and REACH unaffected status

Substitute parts must match all these parameters to ensure functional and mechanical compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

GD75232PWR is the primary parametric equivalent. This part is manufactured by Texas Instruments (same OEM as the main part), maintains identical electrical specifications and supply voltage range, and carries active product status. It is available in higher inventory quantities (74,253 pcs) and is offered in Cut Tape and Digi-Reel packaging formats. This substitute provides direct functional replacement with no design modifications required.

ST75185CTR is the manufacturer-recommended alternative from STMicroelectronics. While it maintains identical driver/receiver configuration, duplex mode, data rate, and package type, the supply voltage range is restricted to 4.5V ~ 5.5V (narrower than the main part's ±7.5V ~ 15V range). This substitute is suitable only for designs operating within the 4.5V ~ 5.5V window. The moisture sensitivity level is elevated to MSL 3 (168 hours) compared to the main part's MSL 1. Both substitutes maintain ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can GD75232PWR be used as a direct replacement for GD75232PWRG4?

A: Yes. GD75232PWR is a parametric equivalent with identical electrical specifications, supply voltage range, and package configuration. No circuit modifications are required.

Q: What is the key difference between GD75232PWR and ST75185CTR?

A: The primary difference is supply voltage range. GD75232PWR supports 5V, ±7.5V ~ 15V, while ST75185CTR is limited to 4.5V ~ 5.5V. ST75185CTR also has a higher moisture sensitivity level (MSL 3 vs. MSL 1). Select based on your circuit's supply voltage requirements.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 20-TSSOP package with identical physical dimensions (0.173", 4.40mm width) and are surface mount compatible.

Q: Does the obsolete status of GD75232PWRG4 affect substitute selection?

A: The obsolete status indicates the main part is no longer in production. Both GD75232PWR and ST75185CTR carry active product status, making them suitable for new designs and ongoing production.

Q: Are there compliance or certification differences between the substitutes?

A: All three parts are ROHS3 compliant and REACH unaffected. The moisture sensitivity level differs: GD75232PWR and GD75232PWRG4 are MSL 1 (unlimited), while ST75185CTR is MSL 3 (168 hours). Consider storage and handling requirements for your application.
