ULN2002AS16-13 Equivalent & Substitute Parts

Part Overview

The ULN2002AS16-13 is a power relay driver IC manufactured by Diodes Incorporated, designed for driving relays and solenoids with 7 NPN outputs in a 1:1 configuration. This component operates at a maximum load voltage of 50V with 500mA output current per channel and is housed in a 16-SOIC surface mount package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative packaging formats are required, or when sourcing from different manufacturers is preferred for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ULN2002AS16-13 is determined by the following critical parameters:

• Output Configuration: Low side driver with 7 NPN outputs
• Electrical Specifications: 50V maximum load voltage, 500mA maximum output current, 1:1 input-to-output ratio
• Package Format: 16-SOIC surface mount package with 0.154" width (3.90mm)
• Interface Type: Parallel inverting input
• Environmental Compliance: ROHS3 compliance and unlimited moisture sensitivity

Substitute parts must maintain identical electrical performance characteristics, package dimensions, and pin configuration. Packaging format (Tape & Reel, Cut Tape, or Tube) does not affect functional equivalence but may impact procurement and handling requirements.

Parameter Comparison

Engineering Selection Recommendations

ULN2002D1013TR (STMicroelectronics) is the manufacturer-recommended direct substitute. This part maintains identical electrical specifications and package format as the ULN2002AS16-13. The primary difference is the reduced operating temperature range (-40°C ~ 85°C versus -40°C ~ 105°C), which may be a limiting factor in high-temperature applications. Both parts are ROHS3 compliant and carry active product status.

ULQ2003ATDG4Q1 and ULQ2003ATDRG4Q1 (Texas Instruments) are functionally equivalent alternatives with Darlington output configuration instead of standard NPN. These parts maintain the same electrical performance envelope (50V, 500mA) and package format. Both carry AEC-Q100 automotive qualification and operate across the full -40°C ~ 105°C temperature range. However, both parts are designated as Last Time Buy, indicating limited future availability. The primary difference between these two is packaging format: ULQ2003ATDG4Q1 is supplied in Tube format, while ULQ2003ATDRG4Q1 is supplied in Tape & Reel format.

MC1413DR2G (onsemi) is a 7 NPN Darlington transistor array with equivalent electrical specifications. This part operates at a maximum junction temperature of 150°C and is suitable for high-temperature environments. The Darlington configuration provides higher current gain compared to standard NPN outputs. This part is in active production status with ROHS3 compliance.

Selection should prioritize parts with active product status for long-term availability. The ULN2002D1013TR from STMicroelectronics is recommended as the primary substitute when operating temperature requirements do not exceed 85°C. For applications requiring the full -40°C ~ 105°C temperature range with active product status, the MC1413DR2G from onsemi provides a viable alternative with Darlington output characteristics.

Frequently Asked Questions (FAQ)

Q: Can MC1413DR2G be used as a direct replacement for ULN2002AS16-13?

A: MC1413DR2G is functionally equivalent within the specified electrical parameters (50V, 500mA, 7 outputs, 16-SOIC package). The primary difference is the Darlington output configuration, which provides higher current gain. Pin configuration and package dimensions are identical, allowing direct PCB substitution. Verify application requirements for Darlington-specific characteristics such as higher saturation voltage.

Q: What is the difference between ULQ2003ATDG4Q1 and ULQ2003ATDRG4Q1?

A: Both parts are electrically identical with the same specifications and performance characteristics. The difference is packaging format only: ULQ2003ATDG4Q1 is supplied in Tube packaging, while ULQ2003ATDRG4Q1 is supplied in Tape & Reel packaging. Selection depends on procurement and assembly line requirements. Both parts carry Last Time Buy status.

Q: Why does ULN2002D1013TR have a lower maximum operating temperature than ULN2002AS16-13?

A: ULN2002D1013TR from STMicroelectronics specifies a maximum operating temperature of -40°C ~ 85°C, compared to -40°C ~ 105°C for the ULN2002AS16-13 from Diodes Incorporated. This is a manufacturer specification difference and does not indicate inferior quality. Applications operating within the 85°C limit can use this part without performance degradation. For applications requiring operation above 85°C, select alternatives with extended temperature ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts (MC1413DR2G, ULN2002D1013TR, ULQ2003ATDG4Q1, and ULQ2003ATDRG4Q1) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of the ULN2002AS16-13.

Q: What does "Last Time Buy" status mean for ULQ2003 parts?

A: Last Time Buy indicates that Texas Instruments has announced end-of-life for these products. Existing inventory may be available, but no new production is planned. These parts should be considered for applications where long-term availability is not critical, or as interim solutions while transitioning to active-status alternatives.

Q: Can these parts be used interchangeably in automotive applications?

A: ULQ2003ATDG4Q1 and ULQ2003ATDRG4Q1 carry AEC-Q100 automotive qualification, making them suitable for automotive-grade applications. The ULN2002AS16-13, ULN2002D1013TR, and MC1413DR2G do not carry automotive qualification markings. Verify application requirements before selecting parts for automotive use.
