Parameter Comparison

Engineering Selection Recommendations

For Active Production Applications:

The ULQ2003AQDRQ1 (Texas Instruments) is the primary substitute for the obsolete ULQ2001D1013TR. This part maintains identical electrical specifications (50V, 500mA, 7-channel Darlington output) and mechanical compatibility (16-SOIC package). The ULQ2003AQDRQ1 carries Active product status with extended operating temperature range (-40°C to 105°C) and AEC-Q100 automotive qualification, providing long-term availability and reliability assurance.

For Extended Temperature Applications:

The ULQ2003ATDRG4Q1 (Texas Instruments) offers identical electrical and mechanical specifications with AEC-Q100 automotive qualification. This part is classified as Last Time Buy, indicating limited future availability. Selection of this part is appropriate only when automotive-grade qualification is a design requirement and procurement can be completed within the Last Time Buy window.

For Cost-Optimized Applications:

The ULN2002D1013TR (STMicroelectronics) provides electrical and mechanical compatibility with Active product status and high inventory availability (72,090 pieces). This part differs in output type (NPN versus Darlington) but maintains the same 1:1 input-output ratio, low-side switching configuration, and 50V/500mA electrical ratings. Selection of this part is appropriate when the application does not require the higher current gain characteristics of Darlington output stages.

Regulatory Compliance:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can the ULN2002D1013TR replace the ULQ2001D1013TR in all applications?

A: The ULN2002D1013TR provides electrical and mechanical compatibility with identical voltage (50V), current (500mA), and package specifications (16-SOIC). The primary difference is output type: ULN2002D1013TR uses NPN output while ULQ2001D1013TR uses NPN Darlington output. Applications requiring high current gain benefit from Darlington configuration. Applications with adequate base drive current can use the ULN2002D1013TR.

Q: What is the difference between the ULQ2003AQDRQ1 and ULQ2003ATDRG4Q1?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications and 16-SOIC package compatibility. The ULQ2003AQDRQ1 is Active product status with standard operating temperature range (-40°C to 85°C). The ULQ2003ATDRG4Q1 is Last Time Buy status with extended operating temperature range (-40°C to 105°C). Both carry AEC-Q100 automotive qualification.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are available in 16-SOIC surface mount package with identical footprint dimensions (0.154", 3.90mm width). Packaging format differs: ULN2002D1013TR is available in Cut Tape (CT) and Digi-Reel; ULQ2003AQDRQ1 is available in Cut Tape (CT) and Digi-Reel; ULQ2003ATDRG4Q1 is available in Tape & Reel (TR).

Q: Do all substitute parts meet the same regulatory requirements?

A: All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. The ULQ2003 series parts (ULQ2003AQDRQ1 and ULQ2003ATDRG4Q1) include AEC-Q100 automotive qualification, which is not applicable to the ULQ2001D1013TR or ULN2002D1013TR.

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

A: The ULQ2001D1013TR specifies maximum junction temperature (TJ) of 150°C. The ULN2002D1013TR specifies ambient temperature (TA) range of -40°C to 85°C. The ULQ2003 series parts specify ambient temperature (TA) range of -40°C to 105°C. Temperature specifications use different measurement points (junction versus ambient), requiring application-specific thermal analysis for direct comparison.

Q: Which substitute part has the longest product lifecycle?

A: The ULQ2003AQDRQ1 carries Active product status, indicating ongoing manufacturing and support. The ULQ2003ATDRG4Q1 is Last Time Buy status with limited future availability. The ULN2002D1013TR is Active status. For applications requiring extended product lifecycle, the ULQ2003AQDRQ1 or ULN2002D1013TR are recommended.
