Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS6735IPG4 is determined by the following critical parameters: output voltage (-5V fixed), output current capability (minimum 200mA), input voltage range (4V to 6.2V), package compatibility (8-DIP through-hole), and switching frequency (160kHz). Substitute parts must maintain identical output voltage and input voltage specifications to ensure direct functional replacement without circuit redesign.

Two categories of substitutes are identified:

Direct Topology Match (Buck): TPS6735IP maintains identical electrical specifications and topology, differing only in product status and packaging format.

Enhanced Topology (Buck-Boost): MAX735CPA+ and MAX735EPA+ employ buck-boost topology with increased output current capability (275mA), compatible input/output voltage ranges, and identical package specifications. These parts provide functional equivalence with additional current headroom.

Parameter Comparison

Engineering Selection Recommendations

TPS6735IP is the primary substitute for the TPS6735IPG4. Both parts are manufactured by Texas Instruments with identical electrical specifications, topology, and package configuration. TPS6735IP is currently in active production status with higher inventory availability (3890 pcs), ensuring supply chain continuity. This part is suitable for direct replacement in all applications where the original TPS6735IPG4 was specified.

MAX735EPA+ provides an alternative from Analog Devices Inc./Maxim Integrated with enhanced output current capability (275mA versus 200mA) and identical operating temperature range (-40°C to 85°C). The buck-boost topology offers functional equivalence with improved current headroom. This part is ROHS3 compliant and maintains all critical electrical parameters.

MAX735CPA+ is functionally equivalent to MAX735EPA+ with identical electrical specifications but operates within a narrower temperature range (0°C to 70°C). Selection of this part requires confirmation that the application does not require extended low-temperature operation below 0°C.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can TPS6735IP be used as a direct replacement for TPS6735IPG4?

A: Yes. TPS6735IP is a direct functional equivalent with identical output voltage (-5V), output current (200mA), input voltage range (4V to 6.2V), switching frequency (160kHz), package type (8-DIP), and operating temperature range (-40°C to 85°C). No circuit modifications are required.

Q: What is the difference between the TPS6735 and MAX735 series?

A: Both series provide -5V fixed output with identical input voltage ranges and switching frequencies. The primary difference is topology: TPS6735 uses buck configuration, while MAX735 uses buck-boost configuration. MAX735 parts provide higher output current (275mA) compared to TPS6735 (200mA).

Q: Are the MAX735CPA+ and MAX735EPA+ interchangeable?

A: Both parts are functionally equivalent with identical electrical specifications and package configuration. The difference is operating temperature range: MAX735CPA+ operates from 0°C to 70°C, while MAX735EPA+ operates from -40°C to 85°C. Selection depends on application temperature requirements.

Q: Is the 8-DIP package compatible with existing PCB layouts?

A: Yes. All substitute parts use the same 8-DIP (0.300", 7.62mm) through-hole package as the original TPS6735IPG4. PCB footprints and mounting requirements remain unchanged.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. TPS6735IP, MAX735CPA+, and MAX735EPA+ are all ROHS3 compliant and REACH unaffected, maintaining regulatory compatibility with the original specification.
