Substitute Part Grouping Explanation

Substitute parts for the TPS76301DBVR are classified into two categories based on parametric equivalence and manufacturer recommendation:

Parametric Equivalents (Same Electrical and Mechanical Specifications): TPS76301DBVT and TPS76301QDBVRQ1 maintain identical electrical performance parameters: 150mA output current, 1.5V to 6.5V adjustable output range, 10V maximum input voltage, 100 µA quiescent current, 60dB PSRR at 1kHz, and identical protection features. Both devices use the SOT-23-5 package. The primary distinction is packaging format (Cut Tape vs. Digi-Reel) and automotive qualification grade for the Q1 variant.

Manufacturer Recommended Substitute (Enhanced Specifications): The AP2205-W5-7 from Diodes Incorporated is identified as a manufacturer-recommended alternative. This device exceeds the TPS76301DBVR specifications in output current (250mA vs. 150mA), input voltage range (24V vs. 10V), and output voltage range (1.24V to 22V vs. 1.5V to 6.5V). The AP2205-W5-7 uses SOT-25 packaging and includes 0.5V dropout specification at 150mA.

Substitution eligibility is determined by: identical output configuration (Positive), identical output type (Adjustable), single regulator configuration, matching protection features (Over Current, Over Temperature, Reverse Polarity), enable control capability, identical operating temperature range (-40°C to 125°C), Surface Mount mounting type, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

TPS76301DBVT: Direct parametric equivalent to TPS76301DBVR with identical electrical specifications and SOT-23-5 packaging. Selection is appropriate for applications requiring standard commercial-grade linear regulation with 150mA output capacity. Both devices maintain Active product status and ROHS3 compliance. Differentiation is limited to packaging format (Cut Tape & Digi-Reel vs. alternative reel configuration).

TPS76301QDBVRQ1: Parametric equivalent with automotive-grade qualification (AEC-Q100). This variant is required for automotive applications subject to AEC-Q100 reliability standards. Electrical performance and package specifications remain identical to the base TPS76301DBVR. Higher inventory availability (239,585 units) supports extended lead-time applications.

AP2205-W5-7: Manufacturer-recommended substitute from Diodes Incorporated offering enhanced electrical specifications. This device supports higher input voltage (24V vs. 10V), wider output voltage range (1.24V to 22V vs. 1.5V to 6.5V), and increased output current (250mA vs. 150mA). The AP2205-W5-7 uses SOT-25 packaging instead of SOT-23-5, requiring PCB layout modification. Selection is appropriate for applications requiring higher current capacity or extended input voltage range. Active product status and ROHS3 compliance are maintained.

Frequently Asked Questions (FAQ)

Q: Can TPS76301DBVT be used as a direct replacement for TPS76301DBVR?

A: Yes. TPS76301DBVT is a parametric equivalent with identical electrical specifications, output current (150mA), voltage ranges (1.5V to 6.5V output, 10V input maximum), protection features, and SOT-23-5 packaging. The devices differ only in packaging format (Cut Tape & Digi-Reel configuration). No circuit modifications are required.

Q: When should TPS76301QDBVRQ1 be selected instead of TPS76301DBVR?

A: TPS76301QDBVRQ1 is required for automotive applications requiring AEC-Q100 qualification. Electrical performance and package specifications are identical to TPS76301DBVR. Selection is driven by application compliance requirements, not electrical performance differences.

Q: Is AP2205-W5-7 a direct replacement for TPS76301DBVR?

A: AP2205-W5-7 is not a direct replacement due to package differences (SOT-25 vs. SOT-23-5) and enhanced electrical specifications. The device supports higher input voltage (24V vs. 10V), wider output voltage range (1.24V to 22V vs. 1.5V to 6.5V), and increased output current (250mA vs. 150mA). PCB layout modification is required. Selection is appropriate only when enhanced specifications are required by the application.

Q: What are the key parameters determining substitution eligibility?

A: Substitution eligibility is determined by: identical output configuration (Positive), identical output type (Adjustable), single regulator configuration, matching protection features (Over Current, Over Temperature, Reverse Polarity), enable control capability, identical operating temperature range (-40°C to 125°C), Surface Mount mounting type, and ROHS3 compliance. Electrical specifications (voltage ranges, current ratings) must meet or exceed application requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TPS76301DBVR, TPS76301DBVT, TPS76301QDBVRQ1, and AP2205-W5-7 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All devices maintain identical environmental compliance status.

Q: What is the primary difference between TPS76301DBVR and TPS76301QDBVRQ1?

A: The primary difference is automotive-grade qualification (AEC-Q100) for TPS76301QDBVRQ1. Electrical specifications, package type (SOT-23-5), and performance parameters are identical. The Q1 variant is required for automotive applications; otherwise, both devices are functionally equivalent.
