Substitute Part Grouping Explanation

Substitute parts for the TPS76850QPWPREP are identified based on strict parametric equivalence across electrical and mechanical specifications. The substitution criteria include:

Electrical Parameters (Must Match):

• Output voltage: 5V fixed
• Output current: 1A
• Maximum input voltage: 10V
• Dropout voltage: 0.38V @ 1A
• Quiescent current: 125 µA
• PSRR: 60dB (1kHz)
• Control features: Enable, Power Good
• Protection features: Over Current, Over Temperature, Reverse Polarity
• Operating temperature range: -40°C ~ 125°C

Mechanical Parameters (Must Match):

• Package type: 20-PowerTSSOP
• Mounting type: Surface Mount
• Physical dimensions: 0.173" × 4.40mm Width

Compliance Parameters (Must Match):

• Manufacturer: Texas Instruments
• RoHS Status: ROHS3 Compliant
• Product Status: Active

The identified substitute parts maintain identical electrical performance and mechanical compatibility, differing only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and automotive qualification status where applicable.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TPS76850QPWPREP, TPS76850QPWPR, and TPS76850QPWPRQ1—are Active products from Texas Instruments with identical electrical specifications and mechanical compatibility. Selection between them depends on application requirements and supply chain considerations:

TPS76850QPWPREP and TPS76850QPWPR are standard-grade linear voltage regulators suitable for general industrial and consumer applications. Both are ROHS3 compliant and provide equivalent performance. The primary difference is packaging format: TPS76850QPWPREP is supplied in Tape & Reel format with 858 pcs in stock, while TPS76850QPWPR is also Tape & Reel with higher inventory (3188 pcs).

TPS76850QPWPRQ1 is the automotive-grade variant, qualified to AEC-Q100 standards and suitable for automotive applications requiring enhanced reliability and traceability. This part is supplied in Cut Tape & Digi-Reel format with 5100 pcs in stock. The automotive qualification introduces stricter manufacturing and testing protocols, making it appropriate for safety-critical automotive systems.

All parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across industrial, consumer, and automotive markets.

Frequently Asked Questions (FAQ)

Q: Can TPS76850QPWPR directly replace TPS76850QPWPREP in production?

A: Yes. Both parts are parametrically identical with matching electrical specifications, output voltage (5V), output current (1A), dropout voltage (0.38V @ 1A), and 20-PowerTSSOP package. The only difference is packaging format (both Tape & Reel). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between TPS76850QPWPRQ1 and the other variants?

A: TPS76850QPWPRQ1 is automotive-grade with AEC-Q100 qualification, designed for automotive applications requiring enhanced reliability standards. Electrically and mechanically, it is identical to the standard-grade variants. The automotive qualification affects manufacturing processes and testing protocols, not electrical performance.

Q: Are all three parts suitable for the same circuit design?

A: Yes, all three parts share identical electrical parameters: 5V fixed output, 1A current capacity, 0.38V dropout voltage, 60dB PSRR, and identical protection features (over-current, over-temperature, reverse polarity). Circuit designs do not require modification when substituting between these parts.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape & Digi-Reel packaging formats are supply chain and handling considerations only. Electrical performance, thermal characteristics, and reliability are identical across all packaging formats for these parts.

Q: Which part should be selected for automotive applications?

A: TPS76850QPWPRQ1 is specified for automotive applications due to AEC-Q100 qualification. This qualification ensures compliance with automotive reliability and traceability requirements. Standard-grade variants (TPS76850QPWPREP and TPS76850QPWPR) are not qualified for safety-critical automotive systems.

Q: Are moisture sensitivity levels different between parts?

A: Yes. TPS76850QPWPREP and TPS76850QPWPR have MSL 2 (1 Year), while TPS76850QPWPRQ1 has MSL 3 (168 Hours). This affects storage and handling protocols but does not impact electrical performance or circuit compatibility.
