Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS73615DBVT is determined by the following critical parameters: fixed output voltage of 1.5V, surface mount SOT-23-5 package compatibility, positive output configuration, enable control feature, and operating temperature range of -40°C to 125°C. Output current capacity, quiescent current, dropout voltage, and PSRR characteristics are secondary parameters that define functional equivalence levels. Parts are grouped into two categories: parametric equivalents (matching all critical parameters) and manufacturer-recommended alternatives (meeting core voltage and package requirements with acceptable variations in secondary electrical characteristics).

Parameter Comparison

Engineering Selection Recommendations

TPS73615DBVR is the primary parametric equivalent, offering identical electrical specifications and full output current capacity of 400mA with matching 0.2V dropout voltage. Both devices are Texas Instruments products with Active product status, ensuring long-term availability and support. This part is recommended as the direct replacement for new designs and inventory replenishment.

RT9193-15GB provides full compatibility with the TPS73615DBVT across all critical parameters including SOT-23-5 package, 1.5V output, and -40°C to 125°C operating range. Output current is reduced to 300mA with lower quiescent current of 130 µA. This part is suitable for applications where 300mA output capacity is sufficient and lower power consumption is beneficial. Active product status and ROHS3 compliance confirm long-term viability.

MAX8887EZK15+T meets core voltage and package requirements with 1.5V output in TSOT-23-5 package. Output current is limited to 300mA and operating temperature range is restricted to -40°C to 85°C. This part is suitable only for applications operating within the reduced temperature range and requiring maximum 300mA output current. Quiescent current is significantly lower at 100 µA.

MIC5305-1.5YD5-TR provides 1.5V output in TSOT-23-5 package with -40°C to 125°C operating range. Output current is limited to 150mA, making this part suitable only for low-current applications. This device offers the highest PSRR specification at 85dB to 65dB across 1kHz to 10kHz range.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original TPS73615DBVT.

Frequently Asked Questions (FAQ)

Q: Can TPS73615DBVR be used as a direct replacement for TPS73615DBVT?

A: Yes. TPS73615DBVR is a parametric equivalent with identical output voltage (1.5V), output current (400mA), dropout voltage (0.2V @ 400mA), quiescent current (550 µA), and operating temperature range (-40°C to 125°C). The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Both use SOT-23-5 package with identical pinout and electrical performance.

Q: What is the key limitation when using MAX8887EZK15+T as a substitute?

A: The MAX8887EZK15+T has two significant limitations: output current is reduced to 300mA (versus 400mA), and operating temperature range is limited to -40°C to 85°C (versus -40°C to 125°C). This part is suitable only for applications requiring maximum 300mA output and operating within the reduced temperature specification.

Q: Is MIC5305-1.5YD5-TR suitable for high-current applications?

A: No. MIC5305-1.5YD5-TR is rated for maximum 150mA output current, making it unsuitable for applications requiring the full 400mA capacity of the TPS73615DBVT. This part is appropriate only for low-current 1.5V regulated output applications.

Q: Are all substitute parts available in the same package as the original TPS73615DBVT?

A: The TPS73615DBVT uses SOT-23-5 (SC-74A) package. TPS73615DBVR and RT9193-15GB are also available in SOT-23-5 package. MAX8887EZK15+T and MIC5305-1.5YD5-TR use TSOT-23-5 (thin variant) package, which has identical pinout and footprint compatibility but different physical dimensions. Verify PCB layout clearances if switching between standard and thin SOT-23-5 variants.

Q: Do all substitute parts support the Enable control feature?

A: Yes. All listed substitute parts include Enable control feature, matching the functionality of the TPS73615DBVT.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging provides continuous reel format suitable for high-volume automated assembly. Cut Tape & Digi-Reel format provides individual tape segments or reel segments for lower-volume or mixed-component orders. Both formats contain identical components; packaging format selection depends on assembly process requirements and order volume.
