Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRV591VFPRG4 is determined by strict equivalence across the following critical parameters:

• Package Compatibility: Both parts must use the 32-HLQFP (7x7) surface mount package with 32-LQFP exposed pad configuration
• Electrical Specifications: Supply voltage range (2.8V ~ 5.5V) and operating temperature range (-40°C ~ 85°C) must be identical
• Functional Classification: Both parts must be classified as Thermoelectric Cooler PMICs with PWM power driver functionality
• Compliance Standards: RoHS3 compliance, MSL rating, and REACH status must match
• Base Product Series: Both parts must share the DRV591 base product number

The DRV591VFPR is the manufacturer-recommended substitute, meeting all equivalence criteria while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DRV591VFPR is the direct equivalent substitute for the discontinued DRV591VFPRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, package configuration, and compliance certifications. The DRV591VFPR maintains active product status with higher inventory availability (2595 Pcs in stock versus 1120 Pcs for the original part). No design modifications are required for substitution. Both parts comply with ROHS3 standards, carry identical MSL ratings, and are REACH unaffected. The substitution is electrically and mechanically transparent for thermoelectric cooler applications operating within the specified voltage and temperature ranges.
