L6219DSTR-T Equivalent & Substitute Parts

Part Overview

The L6219DSTR-T is a bipolar motor driver power MOSFET integrated circuit manufactured by Allegro MicroSystems, designed for fully integrated control and power stage applications in brushed DC and stepper motor systems. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part operates with a supply voltage range of 4.75V to 5.25V and supports output currents up to 750mA across four half-bridge configurations, making it suitable for general-purpose motor control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L6219DSTR-T are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Supply voltage range: 4.75V ~ 5.25V (mandatory match)
• Output configuration: Half Bridge (4) (mandatory match)
• Interface type: Parallel (mandatory match)
• Motor types: Bipolar stepper and brushed DC (mandatory match)
• Package type: 24-SOIC surface mount (mandatory match)
• Step resolution: 1, 1/2 (mandatory match)

All substitute parts listed are manufactured by STMicroelectronics under the E-L6219 base product number series. Substitutes are differentiated by output current capability, load voltage range, operating temperature range, and packaging format (tube versus cut tape). Parts with identical electrical specifications but different packaging formats are direct functional equivalents. Parts with reduced output current (500mA versus 750mA) or restricted load voltage ranges represent functional alternatives suitable only for applications within their specified electrical limits.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the L6219DSTR-T in applications requiring 750mA output current and load voltage operation between 10V and 45V, select from the following active STMicroelectronics parts: E-L6219DS, E-L6219DS013TR, E-L6219DSA, or E-L6219DSATR. These parts maintain identical electrical specifications and package form factor.

E-L6219DS and E-L6219DS013TR differ only in packaging format (tube versus cut tape) and operating temperature range (-20°C to 150°C). E-L6219DSA and E-L6219DSATR provide extended operating temperature range (-40°C to 150°C) and are available in tube and cut tape formats respectively. Selection between these groups depends on application temperature requirements and procurement packaging preferences.

E-L6219R and E-L6219R013TR are functional alternatives with reduced output current capability (500mA) and restricted load voltage range (4.5V to 10V). These parts are suitable only for applications operating within these electrical constraints.

All substitute parts maintain ROHS3 compliance and are currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can E-L6219R parts directly replace the L6219DSTR-T?

A: E-L6219R and E-L6219R013TR are not direct replacements. These parts have reduced output current (500mA versus 750mA) and restricted load voltage range (4.5V to 10V versus 10V to 45V). Use these parts only if your application operates within these electrical limits.

Q: What is the difference between E-L6219DS and E-L6219DS013TR?

A: Both parts have identical electrical specifications and package form factor. The difference is packaging format: E-L6219DS is supplied in tube packaging, while E-L6219DS013TR is supplied in cut tape (CT) and Digi-Reel format. Selection depends on procurement and assembly requirements.

Q: Should I select E-L6219DSA for applications requiring extended temperature operation?

A: E-L6219DSA and E-L6219DSATR extend the operating temperature range to -40°C to 150°C compared to -20°C to 150°C for E-L6219DS variants. Select these parts only if your application requires operation below -20°C.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant, matching the compliance status of the original L6219DSTR-T.

Q: What is the load voltage difference between E-L6219DS and E-L6219R?

A: E-L6219DS supports load voltage from 10V to 46V, while E-L6219R supports only 4.5V to 10V. This is a critical parameter for application compatibility.
