XC6505B331PR-G Equivalent & Substitute Parts

Part Overview

The XC6505B331PR-G is a linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device provides a fixed positive output of 3.3V at 200mA with a maximum dropout voltage of 0.24V @ 100mA. The regulator features integrated over-current and over-temperature protection, along with an enable control function. The part is currently in active production status and is supplied in SOT-89-5 surface mount packaging via tape and reel.

Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain component availability across manufacturing cycles. Substitute parts must maintain identical electrical specifications, output characteristics, and physical packaging to ensure direct interchangeability without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the XC6505B331PR-G is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Electrical Equivalence Requirements:

• Fixed output voltage of 3.3V
• Output current rating of 200mA
• Maximum input voltage of 10.5V
• Dropout voltage specification of 0.24V @ 100mA
• Quiescent current of 8 µA
• PSRR of 60dB (1kHz)
• Enable control function
• Over-current and over-temperature protection

Mechanical and Packaging Equivalence Requirements:

• SOT-89-5 package configuration
• Surface mount mounting type
• Identical pin configuration and footprint

Compliance and Environmental Requirements:

• ROHS3 compliance
• Moisture Sensitivity Level 1
• Active product status

Only parts meeting all specified parameters across these categories qualify as direct substitutes. The XC6505B331PR-G belongs to the Torex XC6505 base product family, and substitutes must maintain identical base product characteristics.
