XC6701B332ER-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6701B332ER-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 3.3V output 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 form factor, and operating temperature range. Identification of alternative sources ensures design flexibility, supply chain continuity, and procurement optimization.

Parameter Comparison

Engineering Selection Recommendations

XC6216B332ER-G as Primary Substitute:

The XC6216B332ER-G is a direct parametric equivalent to the XC6701B332ER-G for applications requiring a 3.3V, 150mA linear voltage regulator in a 6-USPC package. Both devices maintain identical electrical specifications for output voltage, current capacity, input voltage range, dropout voltage, and operating temperature. Both devices carry active product status, RoHS3 compliance, and REACH Unaffected designation.

Differentiation Factors:

The XC6216B332ER-G exhibits lower quiescent current (9 µA versus 105 µA) and lower power supply rejection ratio (30dB versus 50dB at 1kHz). These differences do not affect substitution eligibility but indicate design optimization differences between the two device generations. The XC6216B332ER-G is available in Cut Tape and Digi-Reel packaging formats, while the XC6701B332ER-G is supplied in Tape & Reel format.

Compliance Status:

Both parts maintain identical compliance certifications: RoHS3 compliance, MSL 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification. No regulatory barriers exist for substitution.

Frequently Asked Questions (FAQ)

Q: Can the XC6216B332ER-G replace the XC6701B332ER-G in existing designs?

A: Yes. The XC6216B332ER-G is electrically and mechanically equivalent across all critical parameters: 3.3V fixed output, 150mA current capacity, 28V maximum input, 1.7V dropout voltage, -40°C to 85°C operating range, and 6-USPC package form factor. No circuit modifications are required.

Q: What is the significance of the different quiescent current values?

A: The XC6216B332ER-G operates at 9 µA quiescent current compared to 105 µA for the XC6701B332ER-G. This represents improved power efficiency in the XC6216B332ER-G design. For battery-powered or low-power standby applications, the XC6216B332ER-G provides lower idle power consumption. This difference does not affect substitution compatibility.

Q: Are there packaging format differences between these parts?

A: Yes. The XC6701B332ER-G is supplied in Tape & Reel (TR) format, while the XC6216B332ER-G is available in Cut Tape (CT) and Digi-Reel® formats. Both use the identical 6-USPC (1.8x2) package. Packaging format selection depends on assembly equipment and procurement volume requirements, not electrical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the XC6701B332ER-G and XC6216B332ER-G are RoHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, maintain REACH Unaffected status, and share EAR99 ECCN classification. No compliance barriers exist for substitution.

Q: What is the difference in PSRR between these devices?

A: The XC6701B332ER-G provides 50dB power supply rejection ratio at 1kHz, while the XC6216B332ER-G provides 30dB at 1kHz. PSRR measures the regulator's ability to reject input voltage ripple. The higher PSRR of the XC6701B332ER-G provides superior noise rejection in applications with high input ripple. For applications with clean input supplies, both devices perform equivalently.

Q: Are both parts currently in active production?

A: Yes. Both the XC6701B332ER-G and XC6216B332ER-G maintain active product status with Torex Semiconductor Ltd. Both are available from authorized distributors with current inventory.
