Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L6219DS-T are grouped based on strict electrical and mechanical parameter compatibility. The primary substitution criteria are:

Critical Parameters for Substitution:

• Output Configuration: Half Bridge (4)
• Motor Type: Bipolar stepper and brushed DC
• Interface: Parallel
• Package: 24-SOIC form factor
• Supply Voltage: 4.75V ~ 5.25V
• Output Current: 750mA (primary group) or 500mA (secondary group with reduced load voltage capability)
• Operating Temperature Range: -20°C to -40°C minimum, 150°C maximum
• Mounting Type: Surface Mount

Grouping Logic:

Group 1 - Full Electrical Equivalents (750mA Output Current): E-L6219DS, E-L6219DS013TR, E-L6219DSA, E-L6219DSATR

These parts maintain the 750mA output current specification and 10V ~ 46V load voltage range, providing direct functional equivalence to the L6219DS-T.

Group 2 - Reduced Current Variants (500mA Output Current): E-L6219R, E-L6219R013TR

These parts operate at 500mA output current with reduced load voltage range (4.5V ~ 10V), suitable only for applications with lower power requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Full Electrical Equivalence):

Select from Group 1 substitutes (E-L6219DS, E-L6219DS013TR, E-L6219DSA, E-L6219DSATR) when the application requires 750mA output current and load voltages between 10V and 46V. All Group 1 parts are manufactured by STMicroelectronics with active product status, ensuring long-term availability and supply chain stability. These parts are ROHS3 compliant and maintain the same 24-SOIC package footprint as the L6219DS-T.

E-L6219DSA and E-L6219DSATR offer extended operating temperature range (-40°C to 150°C) compared to the original specification (-20°C to 150°C), providing additional thermal margin for demanding applications.

For Reduced Power Applications:

Select E-L6219R or E-L6219R013TR only when the application operates at 500mA output current with load voltages limited to 4.5V ~ 10V. These variants are not suitable for applications requiring the full 750mA capability or higher load voltages.

Packaging Considerations:

E-L6219DS and E-L6219DSA are supplied in Tube packaging. E-L6219DS013TR, E-L6219DSATR, and E-L6219R013TR are supplied in Cut Tape (CT) & Digi-Reel® format. Select packaging based on production volume and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can E-L6219R parts replace L6219DS-T in existing designs?

A: E-L6219R and E-L6219R013TR are not direct replacements. These parts operate at 500mA output current versus the 750mA specification of L6219DS-T, and support only 4.5V ~ 10V load voltage versus 10V ~ 45V. Use these variants only if your application has been specifically designed for reduced current and lower load voltage operation.

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

A: Both parts are electrically identical with 750mA output current and identical electrical specifications. The primary difference is packaging: E-L6219DS is supplied in Tube format, while E-L6219DS013TR is supplied in Cut Tape (CT) & Digi-Reel® format. Select based on your assembly process requirements.

Q: Are E-L6219DSA and E-L6219DSATR suitable for high-temperature applications?

A: E-L6219DSA and E-L6219DSATR support operating temperatures from -40°C to 150°C, extending the lower temperature limit by 20°C compared to E-L6219DS and E-L6219DS013TR (-20°C to 150°C). Select these variants if your application requires operation below -20°C.

Q: Do all substitute parts maintain the same 24-SOIC package footprint?

A: Yes. All substitute parts use the 24-SOIC (0.295", 7.50mm Width) package, ensuring direct PCB footprint compatibility with the L6219DS-T.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (E-L6219DS, E-L6219DS013TR, E-L6219DSA, E-L6219DSATR, E-L6219R, E-L6219R013TR) are ROHS3 compliant and REACH unaffected.

Q: Which substitute part offers the best inventory availability?

A: E-L6219DSATR offers the highest inventory availability at 337,191 pieces, followed by E-L6219R at 80,200 pieces. For full electrical equivalence with standard temperature range, E-L6219DS provides 58,100 pieces in stock.
