TPS77618PWPR Equivalent & Substitute Parts

Part Overview

The TPS77618PWPR 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 500mA with integrated enable and power good control features, along with over-current, over-temperature, and reverse polarity protection. The device operates across -40°C to 125°C and is packaged in a 20-PowerTSSOP surface mount configuration. As an active product with ROHS3 compliance and 968 units in current stock, alternative part numbers exist to support different packaging specifications, inventory availability, and automotive qualification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS77618PWPR are determined by electrical and mechanical parameter equivalence. All substitute candidates maintain identical electrical specifications: 1.8V fixed output, 500mA output current, 10V maximum input voltage, 125 µA quiescent current, 60dB PSRR at 100Hz, and identical control and protection features. All substitutes use the same 20-PowerTSSOP package and surface mount configuration.

The two identified substitutes differ in packaging format and qualification grade:

TPS77618QPWPREP maintains standard commercial-grade specifications with identical electrical and thermal characteristics but differs in packaging designation.

TPS77618QPWPRQ1 is qualified to AEC-Q100 automotive standards with Grade designation, making it suitable for automotive applications where enhanced reliability and qualification documentation are required.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers are active products from Texas Instruments with ROHS3 compliance and REACH unaffected status. Selection between TPS77618PWPR, TPS77618QPWPREP, and TPS77618QPWPRQ1 depends on application requirements and supply chain considerations.

For standard commercial applications, TPS77618PWPR and TPS77618QPWPREP are electrically and mechanically interchangeable. TPS77618QPWPRQ1 is specified for automotive applications requiring AEC-Q100 qualification and automotive-grade reliability documentation. The MSL rating difference (2 versus 3) reflects different moisture sensitivity classifications; TPS77618QPWPRQ1 requires shorter bake-out times (168 hours versus 1 year).

Frequently Asked Questions (FAQ)

Q: Can TPS77618QPWPREP be used as a direct replacement for TPS77618PWPR?

A: Yes. Both parts are electrically and mechanically identical with matching output voltage, current rating, control features, protection features, and 20-PowerTSSOP package configuration. The difference lies in packaging designation and inventory source.

Q: When should TPS77618QPWPRQ1 be selected instead of the standard versions?

A: TPS77618QPWPRQ1 is specified for automotive applications requiring AEC-Q100 qualification. Select this variant when your application requires automotive-grade reliability documentation and qualification traceability.

Q: Are there package compatibility differences between these three parts?

A: No. All three parts use the identical 20-PowerTSSOP (0.173", 4.40mm Width) surface mount package. PCB layout and footprint requirements are identical.

Q: What is the significance of the MSL rating difference?

A: TPS77618PWPR and TPS77618QPWPREP have MSL 2 (1 Year), while TPS77618QPWPRQ1 has MSL 3 (168 Hours). This affects moisture-sensitive device handling procedures. MSL 3 requires bake-out within 168 hours of package opening; MSL 2 allows 1 year. Storage and handling protocols must follow the respective MSL classification.

Q: Do all three parts support the same control and protection features?

A: Yes. Enable, Power Good control features and Over Current, Over Temperature, Reverse Polarity protection are identical across TPS77618PWPR, TPS77618QPWPREP, and TPS77618QPWPRQ1.
