SP6201EM5-L-1-5 Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The SP6201EM5-L-1-5 is a linear voltage regulator IC manufactured by MaxLinear, Inc., designed to deliver a fixed 1.5V output at 200mA in a compact SOT-23-5 surface mount package. This device is classified as a Power Management PMIC and has been discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and production continuity. The regulator features enable control, over-current protection, and over-temperature protection across an operating range of -40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SP6201EM5-L-1-5 are selected based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Output voltage: Fixed 1.5V
• Output configuration: Positive
• Package type: SOT-23-5 compatible
• Mounting type: Surface Mount
• Control features: Enable function
• Protection: Over-current and over-temperature protection
• Operating temperature range: Minimum -40°C to 125°C

Secondary Compatibility Factors:

• Maximum input voltage: 6V or higher
• Output current capability: Equal to or greater than 200mA
• RoHS compliance status
• Moisture sensitivity level: MSL 1 (Unlimited)

The two substitute parts identified meet these criteria with variations in output current capacity and quiescent current specifications.

Parameter Comparison

Engineering Selection Recommendations

MAX8888EZK15+T (Analog Devices Inc./Maxim Integrated)

This part is the manufacturer-recommended substitute with higher output current capability (300mA vs. 200mA). It is actively produced and ROHS3 compliant. The maximum input voltage is 5.5V, which is 0.5V lower than the original part. The operating temperature range is limited to -40°C to 85°C, which is 40°C narrower than the original specification. Additional features include Power Good output and short-circuit protection. This substitute is suitable for applications where the reduced input voltage and temperature range are acceptable and where higher output current capacity provides design margin.

MIC5256-1.5YM5-TR (Microchip Technology)

This part maintains the same package type (SOT-23-5) and maximum input voltage (6V) as the original SP6201EM5-L-1-5. It is actively produced and ROHS3 compliant. The output current is reduced to 150mA, which is 50mA below the original specification. The operating temperature range matches the original at -40°C to 125°C. Additional protection includes Under Voltage Lockout (UVLO). This substitute is suitable for applications where the full temperature range is required and output current requirements do not exceed 150mA.

Frequently Asked Questions (FAQ)

Q: Can MAX8888EZK15+T be used as a direct replacement for SP6201EM5-L-1-5?

A: MAX8888EZK15+T is functionally compatible for the 1.5V fixed output and SOT-23-5 package. However, the maximum input voltage is 5.5V versus 6V for the original part, and the operating temperature range is limited to -40°C to 85°C instead of -40°C to 125°C. Verify that your application does not require operation above 85°C or input voltages between 5.5V and 6V.

Q: Can MIC5256-1.5YM5-TR be used as a direct replacement for SP6201EM5-L-1-5?

A: MIC5256-1.5YM5-TR is functionally compatible for the 1.5V fixed output, SOT-23-5 package, and full operating temperature range (-40°C to 125°C). The output current is limited to 150mA versus 200mA for the original part. Use this substitute only if your application requires no more than 150mA output current.

Q: What are the package compatibility considerations?

A: The original SP6201EM5-L-1-5 uses SOT-23-5 (SC-74A) packaging. MAX8888EZK15+T uses TSOT-23-5 (thin variant), which has the same pin configuration and footprint but with tighter dimensional tolerances. MIC5256-1.5YM5-TR uses standard SOT-23-5 (SC-74A), identical to the original. Both substitutes are surface mount compatible with the original PCB layout.

Q: How do quiescent current differences affect circuit design?

A: The original SP6201EM5-L-1-5 has a quiescent current of 45 µA. MAX8888EZK15+T draws 100 µA, and MIC5256-1.5YM5-TR draws 150 µA. In battery-powered or low-power standby applications, the higher quiescent current of the substitutes will increase idle power consumption. Select based on your application's power budget requirements.

Q: Are all parts RoHS compliant?

A: Yes. The original SP6201EM5-L-1-5 is RoHS Compliant. Both substitutes (MAX8888EZK15+T and MIC5256-1.5YM5-TR) are ROHS3 Compliant, meeting current environmental standards.
