ULN2002ANE4 Equivalent & Substitute Parts

Part Overview

The ULN2002ANE4 is a power relay driver IC manufactured by Texas Instruments, designed for driving inductive loads such as relays and solenoids. This 7-channel NPN transistor array operates at 50V maximum load voltage with 500mA output current per channel in a 16-DIP through-hole package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts maintain the same electrical specifications and package compatibility while offering improved availability and product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ULN2002ANE4 is determined by the following critical parameters:

• Number of Outputs: 7 channels
• Output Type: NPN configuration
• Voltage - Load (Max): 50V
• Current - Output (Max): 500mA
• Ratio - Input:Output: 1:1
• Output Configuration: Low Side
• Package / Case: 16-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Interface: Parallel with Inverting Input

Substitute parts are grouped into two categories: direct equivalents (same package and electrical specifications) and upgrades (active product status with extended temperature range or alternative package options). All substitute parts maintain the core electrical parameters required for relay and solenoid driver applications.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the ULN2002ANE4 in through-hole 16-DIP applications, ULN2001A, ULN2002A, and ULN2004A from STMicroelectronics are preferred substitutes. These parts maintain identical package geometry, electrical specifications, and mounting type while offering active product status and extended operating temperature range (-40°C to 85°C). All three parts are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

ULN2002AN from Texas Instruments provides a direct equivalent with the same manufacturer lineage but carries Last Time Buy status, making it suitable only for near-term applications where existing supply chains are established.

ULQ2001A, ULQ2003A, and ULQ2004A are categorized as Bipolar (BJT) Transistor Arrays rather than Power Management ICs. These parts maintain the same electrical performance and 16-DIP package but are classified under a different product category. They are suitable for applications where the transistor array classification is acceptable.

ULN2003A from UMW offers an alternative with active product status but uses a 16-SOIC surface-mount package instead of through-hole DIP, requiring PCB redesign and is not recommended for direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can ULN2002ANE4 be directly replaced with ULN2001A or ULN2002A?

A: Yes. ULN2001A and ULN2002A maintain identical electrical specifications (7 outputs, 50V load voltage, 500mA per channel, 1:1 ratio, low-side NPN configuration) and package geometry (16-DIP through-hole). Both are active products from STMicroelectronics with extended temperature range and are ROHS3 compliant.

Q: What is the difference between ULN2002A and ULQ2001A?

A: Both parts maintain identical electrical performance and 16-DIP package. The primary difference is product categorization: ULN2002A is classified as Power Management (PMIC), while ULQ2001A is classified as Transistors, Bipolar (BJT). Functionally, they are interchangeable for relay and solenoid driver applications.

Q: Why is ULN2003A not recommended as a direct substitute?

A: ULN2003A uses a 16-SOIC surface-mount package instead of the 16-DIP through-hole package of the ULN2002ANE4. This package difference requires PCB redesign and is not suitable for direct board-level substitution in existing through-hole designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (ULN2002AN, ULN2001A, ULN2002A, ULN2003A, ULN2004A, ULQ2001A, ULQ2003A, ULQ2004A) are ROHS3 compliant and REACH unaffected.

Q: What is the temperature operating range difference between the main part and substitutes?

A: The ULN2002ANE4 operates from -40°C to 70°C. Most active substitutes (ULN2001A, ULN2002A, ULN2004A, ULN2003A) extend this range to -40°C to 85°C, providing improved thermal performance. ULQ series parts specify 150°C junction temperature (TJ).

Q: Can ULN2004A replace ULN2002ANE4?

A: Yes. ULN2004A is functionally equivalent with identical electrical specifications and 16-DIP through-hole package. It is an active product from STMicroelectronics with extended temperature range and is suitable for direct substitution.
