XC6701B652PR-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6701B652PR-G is an active linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device provides a fixed positive output of 6.5V at 150mA with integrated over-current and over-temperature protection. The part is currently in active product status with RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including output voltage, current capacity, dropout voltage, package type, and protection features. Alternative models may be required due to inventory availability, supply chain optimization, or design revision cycles.

Substitute Part Grouping Explanation

Substitution eligibility for the XC6701B652PR-G is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

Fixed output voltage of 6.5V
Output current rating of 150mA
Maximum input voltage of 28V
Dropout voltage of 1.15V @ 100mA
SOT-89-5 surface mount package
Positive output configuration
Over-current and over-temperature protection
Operating temperature range of -40°C to 85°C
Enable control feature
RoHS3 compliance

The XC6216B652PR-G meets all mandatory equivalence criteria and qualifies as a parametric equivalent. Both devices are manufactured by Torex Semiconductor Ltd and share identical electrical specifications for voltage regulation, current delivery, and thermal protection. Differences in quiescent current (Iq) and PSRR do not affect substitution eligibility when the primary application requirements are met by the specified output voltage, current capacity, and protection features.

Engineering Selection Recommendations

Both the XC6701B652PR-G and XC6216B652PR-G are active products with full RoHS3 compliance and REACH unaffected status, making them suitable for current design implementations and long-term supply chain planning.

Selection Basis:

The XC6701B652PR-G is the primary part number with 823 units in current inventory. The XC6216B652PR-G serves as a direct parametric equivalent with 1032 units available, offering improved quiescent current performance (9 µA versus 115 µA) while maintaining identical voltage regulation, current delivery, and protection specifications.

Selection between these two parts should be based on:

Inventory availability and lead time requirements
Power consumption constraints in battery-powered or low-power applications (XC6216B652PR-G offers lower Iq)
Noise performance requirements (XC6701B652PR-G provides higher PSRR at 50dB)
PCB layout and thermal management considerations

Both parts are surface-mount devices in SOT-89-5 packaging with identical pinout compatibility, enabling direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the XC6216B652PR-G replace the XC6701B652PR-G in existing designs?

A: Yes. Both devices provide identical output voltage (6.5V), output current (150mA), input voltage rating (28V maximum), dropout voltage (1.15V @ 100mA), and protection features. The SOT-89-5 package pinout is identical, enabling direct PCB substitution without layout modification.

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

A: The XC6701B652PR-G draws 115 µA quiescent current, while the XC6216B652PR-G draws 9 µA. In applications where the regulator operates continuously with minimal load current, the XC6216B652PR-G reduces standby power consumption. This difference is not relevant for applications where load current significantly exceeds quiescent current.

Q: Are there package compatibility concerns?

A: No. Both parts use the SOT-89-5/6 surface-mount package with identical pin assignments. Footprints, solder pad layouts, and thermal characteristics are equivalent.

Q: What is the significance of the PSRR difference?

A: The XC6701B652PR-G provides 50dB PSRR (Power Supply Rejection Ratio) at 1kHz, while the XC6216B652PR-G provides 30dB. PSRR measures the regulator's ability to reject input voltage ripple. Applications requiring superior noise rejection on the output rail should prioritize the XC6701B652PR-G. Most general-purpose applications are unaffected by this 20dB difference.

Q: Are both parts RoHS compliant?

A: Yes. Both the XC6701B652PR-G and XC6216B652PR-G are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity), suitable for standard PCB assembly and storage conditions.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that quiescent current and PSRR specifications do not impose design constraints. Both parts meet identical electrical performance requirements for voltage regulation, current delivery, and thermal protection. Design validation should confirm that the lower PSRR of the XC6216B652PR-G does not impact system noise performance if that part is selected.
