GD75232DBRG4 Equivalent & Substitute Parts

Part Overview

The GD75232DBRG4 is a 3/5 transceiver full RS232 interface IC manufactured by Texas Instruments in a 20-SSOP surface mount package. This part is classified as obsolete, which necessitates identification of active equivalent and substitute components for ongoing design support and procurement continuity. The GD75232DBRG4 operates with dual supply voltages (5V, ±7.5V ~ 15V) and supports data rates up to 120 kbps with full duplex RS232 communication.

Substitute Part Grouping Explanation

Substitution for the GD75232DBRG4 is determined by the following critical parameters: RS232 protocol compliance, 3/5 driver/receiver configuration, full duplex operation, 20-SSOP package geometry, surface mount capability, and ROHS3 compliance. Parts are grouped into two categories based on electrical compatibility:

Category 1: Direct Parametric Equivalent GD75232DBR maintains identical electrical specifications to the main part (120 kbps data rate, 500 mV receiver hysteresis, dual supply voltage support) with the same package footprint. This part differs only in packaging format (Tape & Reel versus individual packaging) and product status (Active).

Category 2: Manufacturer Recommended Substitutes MAX3185 series parts (MAX3185CAP+, MAX3185CAP+T, MAX3185EAP+, MAX3185EAP+T) from Analog Devices Inc./Maxim Integrated provide functional equivalence with enhanced electrical performance. These parts maintain the 3/5 driver/receiver configuration, full duplex RS232 operation, identical 20-SSOP package, and ROHS3 compliance. Differences include higher data rate capability (230 kbps versus 120 kbps), modified receiver hysteresis (650 mV versus 500 mV), and restricted supply voltage range (4.5V ~ 5.5V versus dual supply support). Operating temperature range varies by variant.

Parameter Comparison

Engineering Selection Recommendations

GD75232DBR is the primary direct replacement for GD75232DBRG4. Both parts maintain identical electrical specifications and package geometry. The GD75232DBR is currently in active production status, ensuring long-term availability and supply chain stability. Selection of GD75232DBR is appropriate for applications requiring exact electrical parameter matching and dual supply voltage support.

MAX3185 series (CAP+ and EAP+ variants) provides functional substitution with enhanced performance characteristics. These parts are suitable for applications where the restricted supply voltage range (4.5V ~ 5.5V single supply) is compatible with system design. The MAX3185EAP+ and MAX3185EAP+T variants extend operating temperature range to -40°C ~ 85°C, supporting industrial and extended temperature applications. All MAX3185 variants are in active production with established supply availability.

Selection between packaging formats (Tube versus Tape & Reel) depends on procurement volume and assembly process requirements. All parts maintain ROHS3 compliance and identical package footprints, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX3185 parts directly replace GD75232DBRG4 in existing designs? A: MAX3185 parts are functionally equivalent for RS232 3/5 transceiver applications with identical package footprints. However, designs utilizing dual supply voltages (±7.5V ~ 15V) must be modified to operate within the MAX3185 single supply range (4.5V ~ 5.5V). Receiver hysteresis differs (650 mV versus 500 mV), which may affect noise margin characteristics in specific applications.

Q: What is the difference between GD75232DBR and GD75232DBRG4? A: Both parts are electrically identical with matching specifications and package geometry. The primary difference is packaging format: GD75232DBRG4 uses individual packaging while GD75232DBR is supplied in Tape & Reel format. GD75232DBR is currently active in production.

Q: Are all substitute parts ROHS3 compliant? A: Yes. GD75232DBR, MAX3185CAP+, MAX3185CAP+T, MAX3185EAP+, and MAX3185EAP+T are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Which MAX3185 variant should be selected for industrial temperature applications? A: MAX3185EAP+ and MAX3185EAP+T support extended operating temperature range (-40°C ~ 85°C) suitable for industrial environments. MAX3185CAP+ and MAX3185CAP+T operate within 0°C ~ 70°C range, matching the original GD75232DBRG4 specification.

Q: Does packaging format (Tube versus Tape & Reel) affect electrical performance? A: No. Packaging format affects only procurement, storage, and assembly process compatibility. Electrical specifications and performance are identical between Tube and Tape & Reel variants of the same part number base.
