Key Parameters

Substitute Part Grouping Explanation

Substitution of the GD75232PWR-ND is determined by strict equivalence across the following critical parameters:

Protocol & Functional Requirements: RS232 protocol compliance with full-duplex operation and 3 drivers/5 receivers configuration.

Electrical Specifications: Receiver hysteresis of 500 mV, data rate of 120 Kbps, and dual supply voltage support (5V and ±7.5V ~ 15V).

Physical & Environmental Constraints: 20-TSSOP surface mount package with 0.173" width (4.40mm), operating temperature range of 0°C ~ 70°C, and MSL rating of 1.

Compliance & Quality Standards: ROHS3 compliance and equivalent moisture sensitivity classification.

The substitute part GD75232PWR meets all these criteria and is classified as active product status, making it a direct functional and electrical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The GD75232PWR is the direct substitute for the obsolete GD75232PWR-ND. Both parts are manufactured by Texas Instruments and share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: GD75232PWR-ND is obsolete, while GD75232PWR maintains active production status.

Selection of GD75232PWR is supported by:

Product Availability: Active product status ensures continued manufacturing and supply chain support, eliminating obsolescence risk associated with the GD75232PWR-ND.

Compliance Continuity: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental requirements are preserved.

Electrical & Functional Equivalence: Identical transceiver configuration, RS232 protocol support, supply voltage specifications, and operating temperature range guarantee direct functional replacement without circuit redesign.

Packaging Compatibility: Identical 20-TSSOP package dimensions and surface mount characteristics ensure PCB layout compatibility without modification.
