Engineering Selection Recommendations

S-1315A2J-M5T1U3 (ABLIC Inc.) — Recommended Primary Substitute

The S-1315A2J-M5T1U3 is the optimal parametric equivalent for the XC6501C28AMR-G. Both devices share identical output voltage (2.85V) and output current (200mA) specifications, matching operating temperature range (-40°C to 85°C), and equivalent protection architecture (over-current). The ABLIC part demonstrates superior performance characteristics with lower voltage dropout (0.28V vs 0.36V) and significantly reduced quiescent current (1 µA vs 20 µA), resulting in improved power efficiency. Both parts are ROHS3 compliant with MSL 1 rating and active product status. The SOT-23-5 package is footprint-compatible with the original SC-74A specification. Inventory availability is 861 units.

TLV70228PDBVT (Texas Instruments) — Secondary Functional Substitute

The TLV70228PDBVT functions as a substitute when higher output current capacity or extended temperature operation is required. The output voltage of 2.8V falls within acceptable tolerance of the 2.85V specification (±0.05V). The device provides 300mA output current, exceeding the 200mA requirement. Enhanced protection features include over-temperature, reverse polarity, and under-voltage lockout in addition to over-current protection. Operating temperature extends to 125°C (vs 85°C for the original). PSRR performance is superior at 68dB. The part is ROHS3 compliant with MSL 1 rating and active product status. Inventory availability is 7080 units. The SOT-23-5 package is footprint-compatible with SC-74A specification.

All substitute parts maintain compliance with ROHS3 and REACH requirements, possess unlimited moisture sensitivity levels, and are classified as active products with confirmed new original inventory.

Frequently Asked Questions (FAQ)

Q1: Can the S-1315A2J-M5T1U3 be used as a direct replacement for the XC6501C28AMR-G?

A: Yes. The S-1315A2J-M5T1U3 is a parametric equivalent with identical output voltage (2.85V) and output current (200mA). Both devices operate across -40°C to 85°C and include enable control with over-current protection. The SOT-23-5 package is footprint-compatible with the original SC-74A specification. The ABLIC part offers improved voltage dropout and lower quiescent current.

Q2: What is the voltage tolerance between the XC6501C28AMR-G (2.85V) and TLV70228PDBVT (2.8V)?

A: The voltage difference is 0.05V, representing a 1.7% deviation. This falls within acceptable tolerance for most linear regulator applications where the output voltage specification permits ±0.05V variation. Applications with tighter voltage regulation requirements should use the S-1315A2J-M5T1U3, which matches the 2.85V specification exactly.

Q3: Can the TLV70228PDBVT be used in applications requiring exactly 200mA output?

A: Yes. The TLV70228PDBVT is rated for 300mA output current, which exceeds the 200mA requirement. The device operates within specification at 200mA output. The higher current rating provides design margin and does not affect performance at lower load currents.

Q4: Are there package compatibility concerns when substituting SOT-23-5 for SOT-25?

A: Both SOT-23-5 and SOT-25 packages conform to SC-74A footprint specifications. The pinout and pad layout are compatible for PCB assembly. No design modifications are required for package substitution between these devices.

Q5: Which substitute part has the lowest power consumption in standby mode?

A: The S-1315A2J-M5T1U3 has the lowest quiescent current at 1 µA, compared to 20 µA for the XC6501C28AMR-G and 55 µA for the TLV70228PDBVT. For battery-powered or low-power applications, the ABLIC part is the optimal choice.

Q6: Do all substitute parts include enable control functionality?

A: Yes. Both the S-1315A2J-M5T1U3 and TLV70228PDBVT include enable control features, matching the original XC6501C28AMR-G specification.

Q7: What additional protection features does the TLV70228PDBVT provide?

A: The TLV70228PDBVT includes over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) protection. The original XC6501C28AMR-G and S-1315A2J-M5T1U3 include over-current protection only.

Q8: Are all parts RoHS3 compliant?

A: Yes. The XC6501C28AMR-G, S-1315A2J-M5T1U3, and TLV70228PDBVT are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity level.

Q9: Which substitute part offers the best voltage regulation performance?

A: The TLV70228PDBVT provides the highest PSRR at 68dB (1kHz), compared to 50dB for the XC6501C28AMR-G and 55dB for the S-1315A2J-M5T1U3. Higher PSRR indicates superior rejection of power supply noise.

Q10: What is the maximum input voltage for each part?

A: The XC6501C28AMR-G accepts 6V maximum input. Both the S-1315A2J-M5T1U3 and TLV70228PDBVT accept 5.5V maximum input. Applications with input voltages exceeding 5.5V require the original Torex part or design modification.
