Substitute Part Grouping Explanation

Substitution of the L6219R is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters: Motor driver capability for bipolar stepper and brushed DC motor applications with identical output configuration (four half-bridge stages), parallel interface control, and matching step resolution options (1, 1/2).

Power Specifications: Supply voltage range of 4.75V to 5.25V, load voltage range of 4.5V to 10V, and output current rating of 500mA.

Thermal and Environmental: Operating temperature range of -20°C to 150°C (junction temperature), RoHS3 compliance, and REACH unaffected status.

Mechanical and Packaging: Surface mount technology in 24-SOIC package format with 0.295" (7.50mm) width specification.

The E-L6219R meets all these parameters and is classified as an active product, making it a direct parametric equivalent suitable for substitution in applications currently using the obsolete L6219R.

Parameter Comparison

Engineering Selection Recommendations

The E-L6219R is the direct parametric equivalent for the obsolete L6219R. All electrical specifications, thermal characteristics, mechanical dimensions, and regulatory compliance certifications are identical between the two parts.

Product Status Consideration: The L6219R is classified as obsolete, while the E-L6219R maintains active product status. For new designs and production continuity, the E-L6219R is the appropriate selection.

Compliance and Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions.

Packaging and Handling: The E-L6219R is supplied in tube packaging, whereas the original L6219R packaging specification is not detailed. Both parts utilize identical 24-SOIC surface mount packages with matching moisture sensitivity levels (MSL 3, 168 hours), requiring equivalent handling and storage protocols.

Inventory and Availability: The E-L6219R demonstrates significantly higher inventory availability (80,200 pieces) compared to the L6219R (5,306 pieces), supporting long-term supply chain stability for production applications.
