L6219DSTR Equivalent & Substitute Parts

Part Overview

The L6219DSTR is a bipolar motor driver IC manufactured by Allegro MicroSystems, designed for fully integrated control and power stage applications in brushed DC and stepper motor systems. This component operates as a half-bridge driver with parallel interface control, supporting step resolutions of 1 and 1/2 in general-purpose motor control applications.

The L6219DSTR is classified as obsolete. Equivalent substitute parts are available from STMicroelectronics under the E-L6219 series, which maintain functional compatibility while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L6219DSTR is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Motor type (Bipolar stepper and brushed DC)
• Output configuration (Half Bridge with 4 outputs)
• Parallel interface control
• Step resolution support (1, 1/2)
• Supply voltage range (4.75V ~ 5.25V)
• Output current capability (750mA minimum)
• Load voltage range (10V ~ 45V minimum)
• Operating temperature range (-20°C ~ 150°C minimum)

Mechanical Compatibility Requirements:

• Package type: 24-SOIC (0.295", 7.50mm Width)
• Surface mount mounting type

STMicroelectronics E-L6219 series parts meet these requirements with the following variants:

Full Electrical Equivalents (750mA output current, 10V ~ 46V load voltage):

• E-L6219DS
• E-L6219DS013TR
• E-L6219DSA
• E-L6219DSATR

Reduced Specification Variant (500mA output current, 4.5V ~ 10V load voltage):

• E-L6219R
• E-L6219R013TR

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Electrical Equivalents):

E-L6219DS, E-L6219DS013TR, E-L6219DSA, and E-L6219DSATR are direct functional replacements for the L6219DSTR. All four parts maintain 750mA output current capability and 10V ~ 46V load voltage range, ensuring compatibility with applications designed for the original component. These parts are manufactured by STMicroelectronics and carry active product status.

E-L6219DSA and E-L6219DSATR offer extended operating temperature range (-40°C ~ 150°C) compared to the standard E-L6219DS and E-L6219DS013TR variants (-20°C ~ 150°C). Selection between these should be based on application temperature requirements.

All STMicroelectronics E-L6219 series substitutes are ROHS3 compliant, addressing the RoHS non-compliance status of the obsolete L6219DSTR.

Packaging Considerations:

E-L6219DS and E-L6219DSA are supplied in Tube packaging. E-L6219DS013TR and E-L6219DSATR are supplied in Cut Tape (CT) & Digi-Reel® packaging. Selection depends on assembly process requirements and volume considerations.

Reduced Specification Variant:

E-L6219R and E-L6219R013TR are not direct equivalents. These parts feature reduced output current (500mA) and restricted load voltage range (4.5V ~ 10V). These variants are suitable only for applications with lower current and voltage requirements than the original L6219DSTR specification.

Frequently Asked Questions (FAQ)

Q: Can E-L6219R or E-L6219R013TR be used as direct replacements for L6219DSTR?

A: No. E-L6219R and E-L6219R013TR have reduced electrical specifications (500mA output current and 4.5V ~ 10V load voltage range) compared to the L6219DSTR (750mA and 10V ~ 45V). These variants are suitable only for applications with lower current and voltage requirements.

Q: What is the difference between E-L6219DS and E-L6219DSA?

A: Both parts are electrically equivalent with identical output current (750mA) and load voltage range (10V ~ 46V). The primary difference is operating temperature range: E-L6219DS operates from -20°C to 150°C, while E-L6219DSA extends to -40°C. Select E-L6219DSA for applications requiring lower temperature operation.

Q: What packaging options are available for E-L6219 substitutes?

A: STMicroelectronics E-L6219 series parts are available in two packaging formats: Tube (E-L6219DS, E-L6219DSA) and Cut Tape & Digi-Reel (E-L6219DS013TR, E-L6219DSATR). Both formats contain the same die and electrical specifications; selection depends on assembly process and volume requirements.

Q: Are all E-L6219 substitutes RoHS compliant?

A: Yes. All STMicroelectronics E-L6219 series parts (E-L6219DS, E-L6219DS013TR, E-L6219DSA, E-L6219DSATR, E-L6219R, E-L6219R013TR) are ROHS3 compliant, addressing the RoHS non-compliance of the obsolete L6219DSTR.

Q: What is the moisture sensitivity level difference between L6219DSTR and E-L6219 substitutes?

A: The L6219DSTR has MSL 1 (unlimited moisture exposure), while all STMicroelectronics E-L6219 series substitutes have MSL 3 (168 hours maximum). This requires appropriate handling and storage procedures during assembly.

Q: Can E-L6219DS013TR and E-L6219DSATR be used interchangeably with E-L6219DS and E-L6219DSA?

A: Yes, within temperature requirements. E-L6219DS013TR is electrically identical to E-L6219DS (both -20°C ~ 150°C), and E-L6219DSATR is electrically identical to E-L6219DSA (both -40°C ~ 150°C). The difference is packaging format only: Tube versus Cut Tape & Digi-Reel.
