XC6501B26AMR-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6501B26AMR-G is an active linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device functions as a positive fixed output voltage regulator delivering 200mA output current with a fixed 2.65V output. The part is currently in active product status with 927 units in stock inventory.

Identification of equivalent and substitute parts becomes necessary when the primary part experiences supply constraints, extended lead times, or when design optimization requires alternative performance characteristics within the same functional category and package specification.

Substitute Part Grouping Explanation

Substitution eligibility for the XC6501B26AMR-G is determined by strict parametric alignment across the following critical criteria:

Mandatory Matching Parameters:

• Output voltage (fixed): 2.65V
• Output current capability: 200mA minimum
• Input voltage maximum: 6V
• Package type: SOT-25 (SC-74A, SOT-753)
• Output configuration: Positive
• Output type: Fixed
• Number of regulators: 1
• Control features: Enable function
• Protection features: Over Current protection
• Operating temperature range: -40°C ~ 85°C minimum
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant

Allowable Parameter Variations: Substitute parts may exhibit improved performance in the following parameters without affecting functional compatibility:

• Voltage dropout (lower values acceptable)
• Quiescent current (lower values acceptable)
• PSRR (higher values acceptable)
• Supply current maximum (lower values acceptable)

The XC6217B26AMR-G qualifies as a parametric equivalent based on full alignment with all mandatory matching parameters and demonstrates superior performance characteristics in dropout voltage, quiescent current, and PSRR specifications.

Engineering Selection Recommendations

Primary Part Selection (XC6501B26AMR-G): Select the XC6501B26AMR-G when the design baseline has been established with this specific part number and supply availability is confirmed. This part maintains active product status with established manufacturing support and 927 units currently in stock inventory.

Substitute Part Selection (XC6217B26AMR-G): The XC6217B26AMR-G is a direct parametric equivalent suitable for substitution when the primary part experiences supply constraints or extended lead times. This substitute part is manufactured by the same supplier (Torex Semiconductor Ltd), maintains identical package specifications (SOT-25), and delivers the same fixed 2.65V output at 200mA current capacity.

Both parts carry ROHS3 compliance certification, MSL Level 1 (Unlimited moisture sensitivity), and operate across the identical temperature range (-40°C ~ 85°C). Both parts are currently in active product status with confirmed inventory availability.

The XC6217B26AMR-G demonstrates superior performance characteristics with reduced voltage dropout (0.17V @ 100mA versus 0.38V @ 200mA), lower quiescent current consumption (8 µA versus 20 µA), and higher power supply rejection ratio (70dB versus 50dB at 1kHz). These improvements result in lower power dissipation and enhanced noise rejection without requiring circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the XC6217B26AMR-G be used as a direct replacement for the XC6501B26AMR-G without circuit modification?

A: Yes. Both parts deliver identical fixed output voltage (2.65V) and output current (200mA) in the same SOT-25 package. Pin configuration, control features (Enable), and protection features (Over Current) are identical. No circuit modification is required for substitution.

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

A: The XC6217B26AMR-G exhibits superior performance in three areas: voltage dropout is reduced from 0.38V to 0.17V, quiescent current is reduced from 20 µA to 8 µA, and PSRR is increased from 50dB to 70dB. These differences result in lower power dissipation and improved noise rejection. All other electrical and mechanical parameters remain identical.

Q: Are both parts available in the same package?

A: Yes. Both the XC6501B26AMR-G and XC6217B26AMR-G are supplied in SC-74A, SOT-753 (SOT-25) package with Surface Mount mounting type. PCB footprint compatibility is confirmed.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 Compliant, carry MSL Level 1 (Unlimited), and are REACH Unaffected. Both maintain active product status with Torex Semiconductor Ltd.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -40°C to 85°C (TA). No thermal performance differences exist between the two parts.

Q: Can the XC6501B26AMR-G be substituted with the XC6217B26AMR-G in high-noise environments?

A: The XC6217B26AMR-G is suitable for high-noise environments due to its superior PSRR specification (70dB versus 50dB at 1kHz). This higher power supply rejection ratio provides enhanced noise filtering capability.

Q: Are there any inventory considerations for substitution?

A: The XC6501B26AMR-G has 927 units in stock, while the XC6217B26AMR-G has 783 units in stock. Both parts maintain adequate inventory for production requirements.
