Substitute Part Grouping Explanation

Substitution eligibility for the TPS2350DG4 is determined by strict equivalence across the following critical parameters:

• Manufacturer & Base Product Number: Both parts must originate from Texas Instruments and share the TPS2350 base product number
• Functional Classification: Both must be 3-channel Hot Swap Controllers for -48V applications
• Electrical Specifications: Identical supply voltage range (-80V ~ -12V), operating temperature range (-40°C ~ 85°C), and programmable feature set (Current Limit, Fault Timeout, OVP, Slew Rate, UVLO)
• Package & Mounting: Identical 14-SOIC surface mount package with matching physical dimensions
• Compliance & Certifications: Both must maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status

The TPS2350D meets all substitution criteria as a direct equivalent with identical electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TPS2350D is the appropriate selection for applications currently specified for the TPS2350DG4. Both components are manufactured by Texas Instruments and maintain identical electrical specifications, package configuration, and compliance certifications.
