L293DNEE4 Equivalent & Substitute Parts

Part Overview

The L293DNEE4 is a bipolar motor driver IC manufactured by Texas Instruments, designed for controlling brushed DC motors and bipolar stepper motors. It integrates both control and power stages in a single 16-DIP package, operating across a supply voltage range of 4.5V to 36V with 600mA output current capability. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Suitable alternatives exist from both Texas Instruments and STMicroelectronics that maintain functional compatibility while offering improved availability and extended operating temperature ranges.

• Motor Type Compatibility: Bipolar stepper and brushed DC motor support
• Output Configuration: Half Bridge (4) topology
• Interface Type: Parallel control interface
• Voltage Range: Supply and load voltage 4.5V ~ 36V
• Package Form Factor: 16-DIP through-hole mounting
• Output Current: Minimum 600mA capability
• Functional Integration: Fully integrated control and power stage

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring direct functional replacement in existing circuit designs without modification to PCB layout or control logic.

Parameter Comparison

Engineering Selection Recommendations

L293DNE (Texas Instruments) is the primary recommended substitute. It maintains identical electrical specifications and operating temperature range to the L293DNEE4 while offering active product status and significantly higher inventory availability (10,200 units). This part is the direct functional equivalent from the original manufacturer.

L293B (STMicroelectronics) provides enhanced output current capability at 1A versus 600mA, with extended operating temperature range (-40°C to 150°C junction temperature). This part is suitable for applications requiring higher thermal margin or increased current headroom. Inventory availability is robust at 16,606 units.

L293D (STMicroelectronics) maintains the 600mA output current specification with extended operating temperature range (-40°C to 150°C junction temperature). This variant uses a PowerDIP package variant while maintaining the 16-DIP form factor. Inventory availability is strong at 17,508 units.

All substitute parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original part. Selection between L293DNE, L293B, and L293D should be based on thermal operating environment requirements and available current budget for the motor load.

Frequently Asked Questions (FAQ)

Q: Can L293DNE directly replace L293DNEE4 without PCB modification?

A: Yes. The L293DNE is functionally identical to the L293DNEE4, with matching pinout, package dimensions (16-DIP 0.300"), voltage specifications (4.5V ~ 36V), and output current (600mA). No circuit or layout changes are required.

Q: What is the difference between L293B and L293D?

A: Both are STMicroelectronics alternatives with identical electrical specifications and extended operating temperature range (-40°C to 150°C). The primary difference is package designation: L293B uses standard 16-DIP, while L293D uses 16-PowerDIP. Both maintain the same 0.300" (7.62mm) physical dimensions and are pin-compatible with L293DNEE4.

Q: Does L293B's higher current rating (1A vs 600mA) affect compatibility?

A: No. Higher current rating indicates greater capability and does not affect compatibility. The L293B can safely operate in applications designed for 600mA output, providing additional thermal margin and current headroom for motor loads.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. L293DNE, L293B, and L293D all carry ROHS3 compliance and REACH unaffected status, matching the regulatory compliance of the original L293DNEE4.

Q: Which substitute offers the best availability?

A: L293B and L293D both offer superior inventory levels (16,606 and 17,508 units respectively) compared to L293DNE (10,200 units). All three maintain active product status with strong supply chain availability.

Q: Can these parts be used in high-temperature environments?

A: L293DNE maintains the original operating temperature range (0°C ~ 70°C). For applications requiring extended temperature operation, L293B and L293D support -40°C to 150°C junction temperature range, providing significantly broader thermal capability.
