DS2003CN/NOPB Equivalent & Substitute Parts

Part Overview

The DS2003CN/NOPB is a 6/0 driver IC manufactured by Texas Instruments in a 16-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The DS2003CN/NOPB operates at 5V supply voltage with an operating temperature range of -40°C to 85°C and is mounted through-hole. Given its obsolete status, active alternatives with compatible electrical and mechanical specifications are required for system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS2003CN/NOPB is determined by the following critical parameters:

• Package Type: 16-DIP through-hole mounting (0.300", 7.62mm)
• Supply Voltage: 5V operation
• Output Configuration: Driver/relay driver functionality
• Operating Temperature Range: -40°C minimum to 70°C or higher maximum
• RoHS Compliance: ROHS3 Compliant status
• Product Availability: Active status preferred for long-term supply

The substitute parts listed below meet these core requirements with compatible electrical and mechanical specifications. Substitutes are grouped by their active product status and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: ULN2003AN (Texas Instruments)

The ULN2003AN is the preferred substitute for the DS2003CN/NOPB. Both parts are manufactured by Texas Instruments, share identical 16-DIP through-hole packaging, and maintain ROHS3 compliance. The ULN2003AN is in active production status, ensuring long-term availability and supply chain stability. Operating temperature range of -40°C to 70°C covers the lower end of the original specification but is suitable for most industrial applications.

Secondary Recommendation: ULQ2003A (STMicroelectronics)

The ULQ2003A provides an active alternative with through-hole 16-DIP packaging and ROHS3 compliance. This part offers an extended operating temperature range up to 150°C (junction temperature), providing thermal margin for demanding applications. The NPN Darlington configuration and 500mA output current align with driver functionality requirements.

Alternative for Surface Mount Applications: ULN2003A (UMW)

The ULN2003A from UMW is an active product with ROHS3 compliance but uses 16-SOIC surface-mount packaging. This option is suitable only for designs that can accommodate surface-mount technology and is not a direct through-hole replacement.

Obsolete Alternative: ULN2004AD16-U (Diodes Incorporated)

The ULN2004AD16-U maintains through-hole 16-DIP packaging and ROHS3 compliance but is classified as obsolete. While it offers an extended operating temperature range (-40°C to 105°C), its obsolete status makes it unsuitable for new designs requiring long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can ULN2003AN directly replace DS2003CN/NOPB in existing designs?

A: Yes. Both parts use identical 16-DIP through-hole packaging (0.300", 7.62mm), operate at compatible voltage levels, and are ROHS3 compliant. Pin-to-pin compatibility and functional equivalence support direct substitution without PCB redesign.

Q: What is the difference between ULN2003A (UMW) and ULN2003AN (Texas Instruments)?

A: The primary difference is packaging. ULN2003A uses 16-SOIC surface-mount packaging, while ULN2003AN uses 16-DIP through-hole packaging. For through-hole applications, ULN2003AN is the correct choice. Both are active products with ROHS3 compliance.

Q: Why is ULN2004AD16-U not recommended despite through-hole packaging?

A: Although ULN2004AD16-U maintains 16-DIP through-hole packaging, it is classified as obsolete. This status creates long-term supply risk and makes it unsuitable for designs requiring sustained component availability.

Q: Does operating temperature range affect substitution suitability?

A: Operating temperature range affects suitability based on application requirements. ULN2003AN operates to 70°C, which covers standard industrial applications. ULN2004AD16-U and ULQ2003A extend to 105°C and 150°C respectively, providing options for higher-temperature environments. Verify application temperature requirements before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—ULN2003A, ULN2003AN, ULN2004AD16-U, and ULQ2003A—are ROHS3 compliant, matching the compliance status of the DS2003CN/NOPB.
