TLE4209AHKLA1 Equivalent & Substitute Parts

Part Overview

The TLE4209AHKLA1 is a motor driver integrated circuit manufactured by Infineon Technologies, designed for DC servo motor applications with integrated control and power stage functionality. This device operates across a supply voltage range of 8V to 18V and delivers up to 800mA output current in a half-bridge configuration. The TLE4209AHKLA1 is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4209AHKLA1 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Base product number (TLE4209 series)
• Voltage supply range (8V ~ 18V)
• Voltage load range (8V ~ 18V)
• Output configuration (Half Bridge with 2 channels)
• Interface type (Parallel)
• Technology platform (Bipolar)
• Motor application type (DC servo capable)
• Operating temperature range (-40°C ~ 150°C TJ)

The TLE4209GXUMA2 qualifies as a substitute based on matching all critical electrical parameters. Differences in packaging format (Surface Mount vs. Through Hole), output current rating (700mA vs. 800mA), and product status (Active vs. Obsolete) are secondary considerations that do not prevent functional substitution when system design accommodates these variations.

Engineering Selection Recommendations

The TLE4209GXUMA2 is the manufacturer-recommended substitute for the obsolete TLE4209AHKLA1. Selection of this substitute is supported by the following engineering factors:

Product Status: The TLE4209AHKLA1 is classified as obsolete, whereas the TLE4209GXUMA2 maintains active product status with current manufacturing support and availability.

Compliance & Certifications: The TLE4209GXUMA2 achieves ROHS3 compliance and maintains REACH unaffected status, aligning with modern regulatory requirements. The main part carries RoHS non-compliant designation.

Electrical Compatibility: Both devices operate within identical voltage supply and load ranges (8V ~ 18V), maintain equivalent output configuration (Half Bridge 2), and support parallel interface control. The output current differential (700mA vs. 800mA) represents a 12.5% reduction that must be evaluated against specific application load requirements.

Packaging Consideration: The transition from 8-DIP through-hole to 14-SOIC surface-mount packaging requires PCB redesign and assembly process modification. This represents the primary implementation constraint for substitution.

Frequently Asked Questions (FAQ)

Q: Can the TLE4209GXUMA2 directly replace the TLE4209AHKLA1 without circuit modification?

A: Electrical substitution is feasible based on matching voltage ranges, output configuration, and interface type. However, the packaging change from 8-DIP through-hole to 14-SOIC surface-mount requires PCB layout redesign and assembly process changes. Pin-to-pin functional compatibility does not exist due to different package formats.

Q: What is the significance of the 100mA output current difference between these parts?

A: The TLE4209AHKLA1 provides 800mA maximum output current, while the TLE4209GXUMA2 provides 700mA. Applications requiring sustained output current above 700mA cannot use the substitute without thermal or load management modifications.

Q: Why does the TLE4209GXUMA2 have more pins (14-pin vs. 8-pin) if it performs the same function?

A: The 14-SOIC package provides additional pins for enhanced functionality and thermal management in the surface-mount format. The core motor driver function remains equivalent across both package types.

Q: Is the TLE4209GXUMA2 suitable for automotive applications?

A: The TLE4209GXUMA2 carries automotive grade designation. The original TLE4209AHKLA1 does not specify automotive qualification.

Q: What compliance advantages does the TLE4209GXUMA2 offer?

A: The TLE4209GXUMA2 is ROHS3 compliant, whereas the TLE4209AHKLA1 is RoHS non-compliant. Both maintain REACH unaffected status. Modern design implementations should prioritize the compliant substitute.
