DS2003TN Equivalent & Substitute Parts

Part Overview

The DS2003TN is a 6/0 driver IC manufactured by Texas Instruments in a 16-DIP package. This component is classified as an interface driver with a 5V supply voltage and operating temperature range of -40°C to 125°C. The DS2003TN is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design and production requirements. Substitute parts must maintain compatibility with the original electrical specifications and through-hole mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS2003TN are selected based on the following critical parameters:

• Mounting Type: Through Hole configuration required for direct PCB compatibility
• Package Type: 16-DIP form factor (0.300", 7.62mm) for pin-to-pin compatibility
• Voltage - Supply: 5V operation capability
• Output Configuration: Driver/relay solenoid driver functionality
• RoHS Compliance: ROHS3 Compliant status for regulatory alignment

The substitute parts listed (ULN2003A, ULN2003AN, ULN2004AD16-U, ULQ2003A) share the 16-DIP through-hole package and are designed for similar driver applications. These parts maintain functional equivalence within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

ULN2003AN (Texas Instruments) is the primary recommended substitute. This part maintains through-hole 16-DIP packaging identical to the DS2003TN, is actively manufactured by the original supplier, and carries ROHS3 compliance. The operating temperature range of -40°C to 70°C covers standard industrial applications, though it does not extend to the full 125°C maximum of the original part.

ULQ2003A (STMicroelectronics) is an alternative for applications requiring extended temperature operation up to 150°C (TJ). This part is actively produced, maintains 16-DIP through-hole configuration, and provides NPN Darlington output type suitable for relay and solenoid driver applications.

ULN2004AD16-U (Diodes Incorporated) is not recommended for new designs due to obsolete product status, despite maintaining compatible 16-DIP packaging and operating temperature range of -40°C to 105°C.

ULN2003A (UMW) is not suitable as a direct substitute due to surface-mount 16-SOIC packaging, which is incompatible with through-hole PCB designs requiring the 16-DIP form factor.

Frequently Asked Questions (FAQ)

Q: Can ULN2003A replace DS2003TN directly on existing PCBs? A: No. ULN2003A uses 16-SOIC surface-mount packaging, while DS2003TN requires 16-DIP through-hole configuration. PCB redesign would be necessary.

Q: What is the primary difference between ULN2003AN and ULQ2003A? A: Both maintain 16-DIP through-hole compatibility. ULN2003AN operates to 70°C maximum, while ULQ2003A extends to 150°C (TJ). ULN2003AN uses Darlington output; ULQ2003A uses NPN Darlington output. Selection depends on temperature requirements.

Q: Is ULN2004AD16-U suitable for new production? A: No. This part is classified as obsolete. ULN2003AN or ULQ2003A are preferred for active production designs.

Q: Do all substitute parts maintain ROHS3 compliance? A: Yes. All listed substitute parts (ULN2003A, ULN2003AN, ULN2004AD16-U, ULQ2003A) are ROHS3 compliant, matching the original DS2003TN specification.

Q: Which substitute part has the widest operating temperature range? A: ULQ2003A supports operation up to 150°C (TJ), exceeding the DS2003TN specification of 125°C. ULN2004AD16-U operates to 105°C. ULN2003AN is limited to 70°C.
