Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GD75232PWRE4 is determined by strict alignment of 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 (0.173", 4.40mm Width)
• Data Rate: Support for 120 Kbps operation
• Supply Voltage Range: Compatibility with the specified voltage operating window
• Operating Temperature Range: 0°C ~ 70°C minimum requirement
• Electrical Characteristics: Receiver hysteresis of 500 mV

Substitute parts are classified into two categories: parametric equivalents (identical specifications from the same manufacturer) and manufacturer-recommended alternatives (functionally equivalent parts from different manufacturers meeting all critical parameters).

Parameter Comparison

Engineering Selection Recommendations

GD75232PWR (Parametric Equivalent): This Texas Instruments part is a direct parametric equivalent to the GD75232PWRE4, with identical electrical specifications and package configuration. The primary distinction is product status: GD75232PWR maintains active production status, ensuring long-term availability and supply chain continuity. This part is recommended as the primary replacement for obsolete GD75232PWRE4 units in both maintenance and new design applications. Both parts carry ROHS3 compliance and identical moisture sensitivity ratings, supporting seamless integration into existing supply chains.

ST75185CTR (Manufacturer-Recommended Alternative): STMicroelectronics ST75185CTR provides functional equivalence across all critical RS232 transceiver parameters: 3/5 driver/receiver configuration, full-duplex operation, 120 Kbps data rate, and identical 20-TSSOP package. This part is suitable for applications where supply diversification is required. Design consideration: ST75185CTR operates within a narrower supply voltage range (4.5V ~ 5.5V) compared to the GD75232PWRE4 (5V, ±7.5V ~ 15V). Applications requiring the extended voltage range must verify compatibility before substitution. ST75185CTR carries ROHS3 compliance and maintains the same operating temperature specification. Moisture sensitivity level is rated at MSL 3 (168 Hours), requiring appropriate handling protocols during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can GD75232PWR be used as a direct replacement for GD75232PWRE4?

A: Yes. GD75232PWR is a parametric equivalent with identical electrical specifications, package type, and functional characteristics. The primary difference is product status: GD75232PWR is in active production, while GD75232PWRE4 is obsolete. Both parts are manufactured by Texas Instruments and carry identical compliance certifications.

Q: What is the key limitation when substituting ST75185CTR for GD75232PWRE4?

A: The supply voltage range differs. GD75232PWRE4 operates at 5V, ±7.5V ~ 15V, while ST75185CTR operates at 4.5V ~ 5.5V. Applications requiring the extended voltage range of the original part must verify that system power supplies are compatible with the narrower ST75185CTR specification before implementation.

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 components. Pin configuration and functional pinout are compatible across all three parts for RS232 transceiver applications.

Q: What are the compliance and regulatory considerations for substitution?

A: All three parts are ROHS3 compliant and carry identical REACH and ECCN classifications (EAR99). Moisture sensitivity differs: GD75232PWRE4 and GD75232PWR are rated MSL 1 (Unlimited), while ST75185CTR is rated MSL 3 (168 Hours). ST75185CTR requires controlled storage conditions and handling protocols during assembly to prevent moisture absorption.

Q: Which substitute part should be selected for new designs?

A: GD75232PWR is recommended for new designs as the primary equivalent. It maintains active production status, identical specifications to the obsolete original part, and identical compliance certifications. ST75185CTR is suitable as a secondary option when supply diversification is required, provided the narrower supply voltage range is compatible with system requirements.
