Substitute Part Grouping Explanation

The ULN2003ADR has been identified as a manufacturer-recommended substitute for the MLA00058DR. Substitution eligibility is determined by the following criteria:

Substitution Basis:

• Manufacturer alignment: Both parts are manufactured by Texas Instruments
• Regulatory compliance: Both parts meet ROHS3 compliance requirements
• Functional category: ULN2003ADR operates as a Power Switch/Driver with Darlington output configuration, providing relay and solenoid driver functionality
• Interface compatibility: Parallel interface configuration supports direct functional replacement in applicable circuit designs
• Environmental rating: ULN2003ADR carries MSL Level 1 (Unlimited), which exceeds the moisture sensitivity requirements of the MLA00058DR

Key Parameters Determining Substitution:

• RoHS compliance status (ROHS3)
• Manufacturer origin (Texas Instruments)
• Output driver configuration (Darlington type)
• Interface type (Parallel)
• Mounting technology compatibility

Engineering Selection Recommendations

Primary Substitute: ULN2003ADR

The ULN2003ADR is the manufacturer-recommended substitute for the MLA00058DR. Selection of this substitute is supported by the following engineering factors:

• Compliance Status: Both components maintain ROHS3 compliance, ensuring regulatory alignment for applications subject to hazardous substance restrictions
• Manufacturer Continuity: Texas Instruments manufactures both the original and substitute part, ensuring consistent quality and reliability standards
• Active Product Status: The ULN2003ADR carries Active product status, providing long-term availability and supply chain stability, contrasting with the Last Time Buy designation of the MLA00058DR
• Moisture Sensitivity Improvement: The ULN2003ADR MSL Level 1 rating provides superior moisture tolerance compared to the MLA00058DR MSL Level 3 rating, reducing handling and storage constraints
• REACH Compliance: The ULN2003ADR is REACH Unaffected, confirming compliance with chemical substance regulations

Design transition to the ULN2003ADR should be evaluated within the context of specific circuit requirements, particularly regarding output configuration, current capacity, and voltage specifications.

Frequently Asked Questions (FAQ)

Q: Why is the MLA00058DR being discontinued?

A: The MLA00058DR carries Last Time Buy status, indicating Texas Instruments has ceased production and will not accept new orders beyond a specified cutoff date. This is a standard lifecycle management practice for components with limited market demand or product portfolio consolidation.

Q: What makes the ULN2003ADR a valid substitute?

A: The ULN2003ADR is designated as the manufacturer-recommended substitute by Texas Instruments. Both components share ROHS3 compliance, Texas Instruments manufacturing origin, and compatible functional categories (power switching and driver applications). The ULN2003ADR provides enhanced moisture sensitivity performance (MSL Level 1 versus MSL Level 3).

Q: Are there packaging differences between MLA00058DR and ULN2003ADR?

A: The MLA00058DR packaging specification is not provided in available documentation. The ULN2003ADR is supplied in 16-SOIC surface mount package (0.154", 3.90mm Width) and is available in Cut Tape (CT) and Digi-Reel® packaging formats. Physical package compatibility must be verified against original circuit board design specifications.

Q: What is the moisture sensitivity difference, and does it matter?

A: The MLA00058DR carries MSL Level 3 (168 Hours), requiring controlled storage and handling conditions. The ULN2003ADR carries MSL Level 1 (Unlimited), eliminating moisture sensitivity constraints. For applications with extended storage periods or humid environments, the ULN2003ADR provides operational advantages.

Q: Can I use ULN2003ADR as a direct replacement without circuit modifications?

A: Functional compatibility depends on circuit-specific requirements including output current capacity (500mA maximum for ULN2003ADR), load voltage (50V maximum), number of required outputs (7 available), and interface configuration (Parallel). Circuit design review is necessary to confirm compatibility with these electrical parameters.

Q: What is the difference between ULN2003ADR and other ULx200xA series variants?

A: The ULN2003ADR is part of the ULx200xA series manufactured by Texas Instruments. Additional variants within this series include ULQ2004D1013TR, ULN2001D1013TR, ULN2003ADR2G, ULQ2003ADR2G, and ULN2003D1013TR. Selection among these variants depends on specific output configuration, current rating, and packaging requirements for the target application.

Q: Is the ULN2003ADR available in adequate quantities?

A: Current inventory for the ULN2003ADR is reported at 1,005,200 pieces in new original stock, indicating robust supply availability. The MLA00058DR maintains 2,600 pieces in current inventory. Procurement planning should prioritize transition to the ULN2003ADR to ensure long-term supply continuity.
