Substitute Part Grouping Explanation

The TPS7A8901RTJR qualifies as a substitute based on the following alignment criteria:

Functional Equivalence: Both devices are dual-output linear voltage regulators from Texas Instruments with positive output configuration and integrated protection features (Over Current, Over Temperature).

Electrical Compatibility: The TPS7A8901RTJR supports output voltage ranges that encompass the fixed outputs of the TPPM0110DWPR (3.3V and 1.8V fall within the 0.8V to 5.2V adjustable range). Current delivery capability of the substitute (2A per output) exceeds the primary output requirement (1.5A) of the main part.

Input Voltage Tolerance: The substitute accepts maximum input voltage of 6.5V, which accommodates the 5.3V maximum of the main part.

Compliance Alignment: Both parts maintain ROHS3 compliance and EAR99 classification, ensuring regulatory consistency.

Key Substitution Parameters:

• Dual-output positive linear regulator topology
• Output voltage capability (fixed or adjustable)
• Current delivery per output channel
• Input voltage range
• Protection feature set
• RoHS and regulatory compliance

Parameter Comparison

Engineering Selection Recommendations

The TPS7A8901RTJR is available as an active product from Texas Instruments, providing supply continuity for applications currently using the TPPM0110DWPR. Both components maintain ROHS3 compliance and identical regulatory classification (EAR99, HTSUS 8542.39.0001).

The substitute offers enhanced specifications including extended operating temperature range (-40°C to 125°C versus 0°C to 55°C), increased current delivery capability (2A per output versus 1.5A and 300mA), and additional protection features (Reverse Polarity protection). The adjustable output configuration of the TPS7A8901RTJR allows fixed voltage operation at 3.3V and 1.8V through external resistor networks.

Package transition from 20-SOIC to 20-WFQFN requires PCB layout modification. Both packages feature exposed pads for thermal management.

Frequently Asked Questions (FAQ)

Q: Can the TPS7A8901RTJR directly replace the TPPM0110DWPR without circuit modifications?

A: The TPS7A8901RTJR requires external resistor networks to set fixed output voltages at 3.3V and 1.8V, whereas the TPPM0110DWPR provides factory-fixed outputs. PCB layout changes are necessary due to package differences (20-SOIC to 20-WFQFN). Functional substitution is possible with design modifications.

Q: What are the key electrical differences between these parts?

A: The primary differences are output type (fixed versus adjustable), current delivery per channel (1.5A/300mA versus 2A/2A), input voltage maximum (5.3V versus 6.5V), and operating temperature range (0°C–55°C versus -40°C–125°C). Both maintain dual-output positive regulation with Over Current and Over Temperature protection.

Q: Are both parts RoHS compliant?

A: Yes, both the TPPM0110DWPR and TPS7A8901RTJR are ROHS3 compliant with identical regulatory status (EAR99, HTSUS 8542.39.0001).

Q: What is the impact of the package change from 20-SOIC to 20-WFQFN?

A: The 20-WFQFN package (4x4mm) is smaller than the 20-SOIC package (7.50mm width). PCB footprint, trace routing, and thermal management design must be re-evaluated. Both packages include exposed pads for thermal dissipation.

Q: Why is the TPPM0110DWPR in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The TPS7A8901RTJR represents the active alternative for new designs and ongoing supply requirements.
