GD75232DWR Equivalent & Substitute Parts

Part Overview

The GD75232DWR is a 3/5 Transceiver Full RS232 interface IC in 20-SOIC packaging manufactured by Texas Instruments. This component operates as a full-duplex RS232 transceiver with integrated drivers and receivers, supporting data rates up to 120 kbps across a wide supply voltage range of 5V and ±7.5V to ±15V. The part is currently in Last Time Buy status, making identification of equivalent and substitute parts essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the GD75232DWR is determined by strict equivalence across the following parameters: RS232 protocol compliance, 3/5 driver/receiver configuration, full-duplex operation, and 20-pin SOIC package format. The substitute parts are grouped into two categories based on packaging and supply voltage specifications:

Category 1: Same Package (20-SOIC) Substitutes

• GD75232DBR: Identical electrical specifications with alternative 20-SSOP package
• MAX3185CWP+: Same 20-SOIC package with enhanced data rate (230 kbps) and restricted supply voltage range (4.5V ~ 5.5V)
• MAX3185CWP+T: Same 20-SOIC package with enhanced data rate (230 kbps) and restricted supply voltage range (4.5V ~ 5.5V), supplied in Tape & Reel format

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature range (0°C ~ 70°C).

Parameter Comparison

Engineering Selection Recommendations

GD75232DBR is the primary substitute when package footprint change is acceptable. This part maintains identical electrical specifications and supply voltage range as the GD75232DWR while offering active product status. The 20-SSOP package (5.30mm width) provides a smaller footprint compared to the 20-SOIC package (7.50mm width), requiring PCB layout modification.

MAX3185CWP+T is the recommended substitute when maintaining the 20-SOIC package footprint is required. This part is supplied in Tape & Reel format, matching the original packaging specification. The enhanced data rate (230 kbps versus 120 kbps) and increased receiver hysteresis (650 mV versus 500 mV) provide improved performance margins. The restricted supply voltage range (4.5V ~ 5.5V) requires verification against system power supply specifications; this part is not suitable for systems requiring the ±7.5V to ±15V supply range.

MAX3185CWP+ is functionally equivalent to MAX3185CWP+T with identical electrical specifications but supplied in Tube packaging format instead of Tape & Reel.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can GD75232DBR be used as a direct replacement for GD75232DWR?

A: GD75232DBR is electrically equivalent with identical RS232 protocol, 3/5 driver/receiver configuration, data rate, and supply voltage specifications. The primary difference is the package format: GD75232DBR uses 20-SSOP (5.30mm width) versus GD75232DWR's 20-SOIC (7.50mm width). PCB layout modification is required for footprint compatibility.

Q: What are the key differences between GD75232DWR and MAX3185CWP+T?

A: Both parts use the 20-SOIC package and maintain full-duplex RS232 operation with 3/5 driver/receiver configuration. MAX3185CWP+T offers enhanced data rate (230 kbps versus 120 kbps) and increased receiver hysteresis (650 mV versus 500 mV). The critical difference is supply voltage: GD75232DWR supports 5V and ±7.5V to ±15V, while MAX3185CWP+T operates only on 4.5V to 5.5V. Substitution is valid only for systems using single 5V supply rails.

Q: Is MAX3185CWP+ suitable as a substitute?

A: MAX3185CWP+ is electrically and functionally equivalent to MAX3185CWP+T with identical specifications. The difference is packaging format: MAX3185CWP+ is supplied in Tube format while MAX3185CWP+T is supplied in Tape & Reel format. Selection depends on procurement and assembly requirements.

Q: Why does GD75232DWR have Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued or is discontinuing production. GD75232DBR, MAX3185CWP+, and MAX3185CWP+T are all active products suitable for long-term design continuity.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for all listed substitutes within their specified operating parameters. Package footprint differences (20-SOIC versus 20-SSOP) and supply voltage restrictions (MAX3185 series) require design verification before implementation.
