Substitute Part Grouping Explanation

Substitute parts for the TPS76815QPWPREP are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Identical output voltage configuration (Positive, Fixed, 1.5V)
Matching output current rating (1A)
Identical input voltage maximum (10V)
Matching quiescent current specification (125 µA)
Identical PSRR performance (60dB at 1kHz)
Matching control features (Enable, Power Good)
Identical protection features (Over Current, Over Temperature, Reverse Polarity)
Compatible operating temperature range (-40°C ~ 125°C)
Identical package type (20-PowerTSSOP)
Same base product number (TPS76815)

Two substitute parts meet these criteria: TPS76815QPWPR (standard commercial grade) and TPS76815QPWPRQ1 (automotive qualified variant).

Engineering Selection Recommendations

TPS76815QPWPR is the primary substitute for the TPS76815QPWPREP. Both parts are commercially graded, currently active in product status, and share identical electrical specifications and packaging. The TPS76815QPWPR offers higher inventory availability (5268 units) compared to the main part. This variant is suitable for standard commercial applications where automotive qualification is not required.

TPS76815QPWPRQ1 is an automotive-qualified variant meeting AEC-Q100 standards with superior moisture sensitivity rating (MSL 1, Unlimited versus MSL 2, 1 Year). This part is discontinued at DiGi Electronics and should be selected only when automotive-grade qualification and extended moisture tolerance are mandatory design requirements. All three parts maintain identical electrical performance and package compatibility.

Frequently Asked Questions (FAQ)

Q: Can TPS76815QPWPR be used as a direct replacement for TPS76815QPWPREP?

A: Yes. Both parts are electrically and mechanically identical with matching output voltage (1.5V fixed), output current (1A), input voltage rating (10V maximum), quiescent current (125 µA), PSRR (60dB at 1kHz), control features (Enable, Power Good), protection features (Over Current, Over Temperature, Reverse Polarity), operating temperature range (-40°C to 125°C), and package type (20-PowerTSSOP). The primary difference is packaging format and inventory availability.

Q: What is the difference between TPS76815QPWPREP and TPS76815QPWPRQ1?

A: The TPS76815QPWPRQ1 is an automotive-qualified variant with AEC-Q100 certification and improved moisture sensitivity rating (MSL 1, Unlimited versus MSL 2, 1 Year). All electrical parameters remain identical. The TPS76815QPWPRQ1 is discontinued at DiGi Electronics and should be used only when automotive qualification is a design requirement.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the identical 20-PowerTSSOP package with 0.173" width and 4.40mm dimensions, ensuring complete pin and footprint compatibility.

Q: Which part should I select for new designs?

A: For new commercial applications, TPS76815QPWPR is recommended due to active product status and higher inventory availability. For automotive applications requiring AEC-Q100 qualification, TPS76815QPWPRQ1 is the appropriate selection, subject to availability confirmation.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for commercial and industrial applications.
