Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS92020D is determined by the following critical parameters:

• Package Compatibility: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Supply Voltage Range: Minimum 11.5V and maximum 18V operation capability
• Output Configuration: Single output topology
• Application Category: AC DC offline switcher for lighting applications
• Regulatory Compliance: ROHS3 compliance and active product status
• Operating Temperature Range: -40°C to 125°C junction temperature

The substitute part MP4032-1GS meets these core substitution criteria while maintaining functional equivalence within the allowed parameter set for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS92020D and MP4032-1GS are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The MP4032-1GS operates within an extended supply voltage range (10.3V to 27V) that encompasses the TPS92020D operating window (11.5V to 18V), providing broader input voltage tolerance. Both devices maintain identical operating temperature specifications (-40°C to 125°C junction temperature) and share the same 8-SOIC surface mount package footprint.

Selection between these parts should be based on specific circuit design requirements, availability, and lead time considerations. Both devices are suitable for AC DC offline switcher applications in lighting systems where single-output topology is required.

Frequently Asked Questions (FAQ)

Q: Can MP4032-1GS directly replace TPS92020D in existing designs?

A: The MP4032-1GS shares the same 8-SOIC surface mount package footprint and operates within compatible supply voltage and temperature ranges. PCB layout compatibility is maintained. However, detailed schematic review is necessary to confirm functional equivalence for your specific application, as internal topology and control characteristics may differ.

Q: What is the significance of the extended voltage range in MP4032-1GS?

A: The MP4032-1GS supports 10.3V to 27V input, compared to TPS92020D's 11.5V to 18V range. This extended range provides design flexibility for applications with variable input voltage conditions, though both parts operate correctly within the TPS92020D's specified range.

Q: Are there package differences between these parts?

A: Both parts use 8-SOIC surface mount packages with 0.154" (3.90mm) width. The MP4032-1GS is specified as 8-SOIC-7A (7 leads), while TPS92020D uses standard 8-SOIC. Pin configuration should be verified against datasheets before substitution.

Q: Do both parts meet current regulatory compliance?

A: Yes. Both TPS92020D and MP4032-1GS are ROHS3 compliant, REACH unaffected, and classified as EAR99 export controlled items with matching HTSUS codes (8542.39.0001).

Q: What is the MSL difference between these parts?

A: TPS92020D has MSL Level 1 (unlimited moisture tolerance), while MP4032-1GS has MSL Level 2 (1 year moisture tolerance). This affects storage and handling requirements, with MP4032-1GS requiring more controlled moisture conditions during storage and prior to assembly.
