Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2370D is determined by the following critical parameters:

• Package Compatibility: Both parts must use 8-SOIC (0.154", 3.90mm Width) surface mount packaging to ensure PCB layout compatibility
• Interface Standard: IEEE 802.3af PoE standard compliance is required for functional equivalence
• Mounting Type: Surface mount technology must be maintained
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be preserved
• Moisture Sensitivity: MSL 1 rating ensures handling and storage compatibility

The TPS2375D meets all these criteria as a manufacturer-recommended substitute, sharing identical package specifications, interface standards, and regulatory certifications with the TPS2370D.

Parameter Comparison

Engineering Selection Recommendations

The TPS2375D is the designated manufacturer-recommended substitute for the TPS2370D. Selection of this substitute is supported by:

• Identical Physical Footprint: Both components use 8-SOIC packaging with matching dimensions (0.154", 3.90mm Width), enabling direct PCB layout compatibility without redesign
• Regulatory Alignment: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory continuity
• Active Product Status: The TPS2375D carries Active product status, providing assured long-term availability and manufacturer support, contrasting with the Obsolete status of the TPS2370D
• Compliance Preservation: Moisture sensitivity level and handling requirements remain unchanged, maintaining existing supply chain and assembly processes

Frequently Asked Questions (FAQ)

Q: Can the TPS2375D be used as a direct replacement for the TPS2370D on existing PCBs?

A: Yes. Both components share identical 8-SOIC package dimensions and surface mount specifications. No PCB layout modifications are required for physical substitution.

Q: Are there differences in supply voltage or current requirements between these parts?

A: The TPS2375D operates within a supply voltage range of 0V to 57V with a supply current of 240µA. The TPS2370D specifications for these parameters were not provided in the comparison data. Refer to the respective Texas Instruments datasheets for detailed electrical characteristic verification.

Q: Does the TPS2375D maintain the same regulatory certifications?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Why is the TPS2370D listed as Obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for this component. The TPS2375D, with Active status, represents the current supported alternative.

Q: Are there any moisture sensitivity or handling differences?

A: No. Both components carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and handling requirements throughout the supply chain.
