XC6221D26AMR-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6221D26AMR-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 with a single output channel rated at 200mA, designed for surface mount applications in the SOT-25 package. The part is currently in active production status with 1031 units in stock inventory.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain disruptions, or end-of-life considerations for the primary component. Equivalent parts must maintain identical electrical performance characteristics and mechanical compatibility within the specified operating parameters.

Substitute Part Grouping Explanation

Substitute parts for the XC6221D26AMR-G are identified based on strict equivalence of the following critical parameters:

Electrical Equivalence Criteria:

• Output voltage (fixed): 2.65V
• Output current rating: 200mA
• Maximum input voltage: 6V
• Voltage dropout: 0.17V @ 100mA
• PSRR: 70dB (1kHz)
• Operating temperature range: -40°C to 85°C
• Protection features: Over Current
• Control features: Enable

Mechanical Equivalence Criteria:

• Package type: SOT-25 (SC-74A, SOT-753)
• Mounting type: Surface Mount
• Tape & Reel packaging format

The XC6217B26AMR-G qualifies as a parametric equivalent substitute because it maintains all critical electrical specifications and mechanical compatibility with the primary part. Both devices are manufactured by Torex Semiconductor Ltd and share identical output voltage, current rating, input voltage limits, dropout voltage, PSRR, temperature range, protection architecture, and package configuration.

Engineering Selection Recommendations

Both the XC6221D26AMR-G and XC6217B26AMR-G are active production components with full compliance to RoHS3 and REACH regulatory requirements. Selection between these parts should be based on the following engineering considerations:

Primary Part (XC6221D26AMR-G): Recommended as the first choice due to higher current inventory availability (1031 units in stock). This part maintains all specified electrical and mechanical parameters for applications requiring a 2.65V, 200mA linear regulator in SOT-25 packaging.

Substitute Part (XC6217B26AMR-G): Qualifies as a direct parametric equivalent with 783 units in stock. The XC6217B26AMR-G exhibits lower quiescent current (8µA versus 50µA), which may provide improved power efficiency in battery-powered or low-power standby applications. This characteristic does not compromise compatibility but represents an enhanced performance attribute.

Both parts are manufactured by the same supplier, share identical regulatory compliance certifications, and are packaged in the same SOT-25 format suitable for surface mount assembly. Selection may be driven by inventory availability, delivery lead times, or application-specific power consumption requirements.

Frequently Asked Questions (FAQ)

Q: Can the XC6217B26AMR-G be used as a direct replacement for the XC6221D26AMR-G in existing designs?

A: Yes. The XC6217B26AMR-G maintains identical output voltage (2.65V), output current (200mA), input voltage limits (6V maximum), voltage dropout (0.17V @ 100mA), PSRR (70dB at 1kHz), operating temperature range (-40°C to 85°C), and package configuration (SOT-25). Both devices feature identical protection and control features. No circuit modifications are required for substitution.

Q: What is the difference in quiescent current between these parts?

A: The XC6221D26AMR-G draws 50µA quiescent current, while the XC6217B26AMR-G draws 8µA. This difference does not affect functional compatibility. The lower quiescent current of the XC6217B26AMR-G may reduce standby power consumption in applications where the regulator remains enabled during low-power modes.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both the XC6221D26AMR-G and XC6217B26AMR-G use identical SOT-25 (SC-74A, SOT-753) packaging and surface mount mounting type. They are compatible with standard reflow soldering processes and require no changes to PCB layout or assembly procedures.

Q: Do these parts have the same regulatory compliance?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is identical (MSL 1, Unlimited) for both components.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection should consider current inventory levels, supply chain availability, and application-specific requirements. The XC6217B26AMR-G may be preferred in applications where minimizing quiescent current is beneficial.

Q: Are there any temperature or voltage rating differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C to 85°C) and accept the same maximum input voltage (6V) with identical dropout voltage specifications (0.17V @ 100mA).
