TPS75418QPWPR Equivalent & Substitute Parts

Part Overview

The TPS75418QPWPR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive 1.8V output at 2A current capacity in a 20-HTSSOP surface mount package. The device is currently in active production status with 3527 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS75418QPWPR are identified based on strict electrical and mechanical parameter equivalence. The critical parameters determining substitution eligibility are:

• Fixed output voltage of 1.8V
• Output current capacity of 2A
• Quiescent current of 125 µA
• PSRR of 60dB at 100Hz
• Identical control features (Enable, Power Good, Reset Output)
• Identical protection features (Over Current, Over Temperature, Reverse Polarity)
• Operating temperature range of -40°C to 125°C
• 20-PowerTSSOP package configuration
• Surface mount mounting type
• ROHS3 compliance and MSL 2 rating

The TPS75218QPWPR and TPS75218QPWPREP variants meet these criteria and are classified as parametric equivalents. Both maintain identical functional specifications and package compatibility with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—TPS75418QPWPR, TPS75218QPWPR, and TPS75218QPWPREP—are active production components from Texas Instruments with ROHS3 compliance and identical MSL ratings. Selection between these parts is based on availability and input voltage specification requirements. The TPS75418QPWPR and TPS75218QPWPR support maximum input voltage of 5.5V, while TPS75218QPWPREP is rated to 5V maximum input. For applications requiring the full 5.5V input range, TPS75418QPWPR or TPS75218QPWPR are appropriate selections. For applications with input voltage limited to 5V or below, all three parts are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can TPS75218QPWPR be used as a direct replacement for TPS75418QPWPR?

A: Yes. Both parts maintain identical electrical specifications including output voltage, output current, quiescent current, PSRR, control features, protection features, and operating temperature range. Package configuration and mounting type are identical. The parts are parametric equivalents.

Q: What is the difference between TPS75218QPWPR and TPS75218QPWPREP?

A: The primary difference is maximum input voltage specification. TPS75218QPWPR supports 5.5V maximum input, while TPS75218QPWPREP is rated to 5V maximum input. All other electrical and mechanical parameters are identical. Selection depends on the application's input voltage requirements.

Q: Are all substitute parts in the same package?

A: Yes. All three part numbers use the 20-PowerTSSOP package with 0.173" width and 4.40mm dimensions. Surface mount compatibility is maintained across all variants.

Q: Do substitute parts have the same compliance certifications?

A: Yes. All parts are ROHS3 compliant with MSL 2 rating (1 Year), REACH Unaffected status, and EAR99 ECCN classification.

Q: Which part should be selected for new designs?

A: For new designs, selection is based on input voltage requirements. If the application requires input voltage up to 5.5V, either TPS75418QPWPR or TPS75218QPWPR are suitable. If input voltage is limited to 5V or below, all three parts are functionally equivalent. Availability and lead time may also influence selection.
