GD65232N Equivalent & Substitute Parts

Part Overview

The GD65232N is a 3/5 transceiver full RS232 interface IC manufactured by Texas Instruments in a 20-DIP through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs, repairs, and production continuity. The GD65232N provides full-duplex RS232 communication with integrated drivers and receivers suitable for legacy serial communication applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GD65232N are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Protocol: RS232
• Number of Drivers/Receivers: 3/5
• Duplex: Full
• Data Rate: 120 Kbps minimum
• Voltage Supply Range: 5V, ±7.5V ~ 15V
• Operating Temperature Range: -40°C ~ 85°C
• Receiver Hysteresis: 500 mV

Mechanical Compatibility Criteria:

• Base Product Number: GD65232
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary substitute identified is the GD65232DWR, which maintains identical electrical specifications while offering a surface-mount 20-SOIC package alternative to the through-hole 20-DIP configuration of the original part.

Parameter Comparison

Engineering Selection Recommendations

The GD65232DWR is the manufacturer-recommended substitute for the GD65232N. Both parts maintain identical electrical specifications and are ROHS3 compliant with unlimited moisture sensitivity rating. The primary distinction is the package format: the GD65232N uses through-hole 20-DIP mounting, while the GD65232DWR uses surface-mount 20-SOIC technology.

Selection between these parts depends on PCB design requirements. Through-hole mounting (GD65232N) is suitable for legacy designs and applications requiring mechanical robustness. Surface-mount technology (GD65232DWR) is appropriate for modern PCB layouts with higher component density and automated assembly processes.

Both parts are obsolete and should be evaluated for long-term availability. Current inventory levels are 811 units for GD65232N and 1204 units for GD65232DWR.

Frequently Asked Questions (FAQ)

Q: Can GD65232DWR directly replace GD65232N in existing designs? A: Electrical substitution is complete. Mechanical substitution requires PCB redesign due to package format differences (through-hole DIP versus surface-mount SOIC).

Q: What are the key electrical parameters that must match for RS232 transceiver substitution? A: Protocol (RS232), driver/receiver count (3/5), duplex mode (Full), data rate (120 Kbps), supply voltage range (5V, ±7.5V ~ 15V), and operating temperature range (-40°C ~ 85°C) must all match.

Q: Are both parts RoHS compliant? A: Yes, both GD65232N and GD65232DWR are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the difference between 20-DIP and 20-SOIC packages? A: 20-DIP is a through-hole package (0.300" width) suitable for traditional PCB assembly. 20-SOIC is a surface-mount package (0.295" width) for modern automated assembly processes.

Q: Why are both parts listed as obsolete? A: Product status reflects manufacturer discontinuation. Availability through authorized distributors may vary. Current inventory should be verified before design commitment.
