Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP6201EM5-L/TR is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Output Configuration: Positive
• Output Type: Adjustable
• Number of Regulators: 1
• Package / Case: SC-74A, SOT-753 (SOT-23-5)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 125°C
• Control Features: Enable function
• Protection Features: Over Current and Over Temperature protection

Performance Parameters:

• Voltage - Input (Max): Must support minimum 5.5V to 6V
• Voltage - Output (Min/Fixed): Must support adjustable range starting at or below 2.5V
• Voltage - Output (Max): Must support 5V to 6V range
• Voltage Dropout: Must not exceed 0.5V at rated current
• Current - Output: Must meet or exceed 200mA requirement

The SP6205EM5-L/TR qualifies as a direct substitute based on these parameters, with the primary enhancement being increased output current capacity (500mA vs. 200mA).

Parameter Comparison

Engineering Selection Recommendations

The SP6205EM5-L/TR is the manufacturer-recommended substitute for the obsolete SP6201EM5-L/TR. Both devices share identical package geometry, pinout, and core functional architecture, enabling direct PCB-level replacement without layout modifications.

The SP6205EM5-L/TR offers the advantage of active product status, ensuring long-term availability and supply chain continuity. The device is RoHS compliant, meeting environmental and regulatory requirements for modern manufacturing standards.

Key design considerations for substitution:

• Output current capacity increases from 200mA to 500mA, providing design margin for applications requiring higher load current
• Minimum output voltage adjusts from 2.5V to 1.25V, expanding the adjustable output range
• Maximum input voltage decreases from 6V to 5.5V; verify input supply does not exceed 5.5V
• Maximum output voltage decreases from 6V to 5V; confirm application requirements do not exceed 5V
• PSRR performance differs across frequency ranges; evaluate noise rejection requirements at specific operating frequencies

Frequently Asked Questions (FAQ)

Q: Can the SP6205EM5-L/TR directly replace the SP6201EM5-L/TR without PCB modifications?

A: Yes. Both devices use identical SC-74A/SOT-753 (SOT-23-5) packaging with matching pinout and footprint. No PCB layout changes are required for physical substitution.

Q: What are the key electrical differences between these parts?

A: The primary differences are output current capacity (200mA vs. 500mA), minimum adjustable output voltage (2.5V vs. 1.25V), and maximum input voltage (6V vs. 5.5V). Verify your application requirements fall within the SP6205EM5-L/TR specifications before substitution.

Q: Is the SP6205EM5-L/TR suitable for applications requiring 6V input?

A: No. The SP6205EM5-L/TR has a maximum input voltage of 5.5V. Applications requiring 6V input must use an alternative part or implement input voltage limiting circuitry.

Q: Does the SP6205EM5-L/TR support output voltages above 5V?

A: No. The maximum adjustable output voltage is 5V. Applications requiring output above 5V are not compatible with this substitute.

Q: What is the impact of the lower PSRR specification on the SP6205EM5-L/TR?

A: The SP6205EM5-L/TR specifies 67dB PSRR at 1kHz, compared to the SP6201EM5-L/TR range of 78dB to 40dB across 100Hz to 400Hz. Evaluate noise rejection requirements at your specific operating frequencies to determine if this difference affects system performance.

Q: Is the SP6205EM5-L/TR RoHS compliant?

A: Yes. The SP6205EM5-L/TR is RoHS compliant, meeting environmental and regulatory standards for restricted substance use.

Q: Can I use the SP6205EM5-L/TR in applications originally designed for 200mA output?

A: Yes. The SP6205EM5-L/TR supports 500mA output, which exceeds the 200mA requirement. The higher current capacity provides design margin and does not negatively impact applications designed for lower current loads.
