Key Parameters

Substitute Part Grouping Explanation

Substitution of the INA239AIDGST is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Identical functional classification as Power Management (PMIC)
• Identical operating temperature range: -40°C ~ 125°C
• Identical power monitor functionality

Mechanical & Physical Compatibility:

• Identical package designation: 10-TFSOP, 10-MSOP (0.118", 3.00mm Width)
• Identical supplier device package: 10-VSSOP
• Identical mounting type: Surface Mount
• Identical moisture sensitivity level: MSL 2 (1 Year)

Regulatory & Compliance Equivalence:

• Identical REACH Status: REACH Unaffected
• Identical ECCN classification: EAR99
• Identical HTSUS code: 8542.39.0001
• RoHS compliance maintained across substitutes

The INA239AIDGSR qualifies as a direct substitute based on complete alignment with all specified parameters.
