XC6501D301GR-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6501D301GR-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 at 3V output with integrated enable control and over-current protection. The part is currently in active production status with 904 units in stock inventory.

Identification of equivalent and substitute parts becomes necessary when the primary part number experiences supply constraints, extended lead times, or when design requirements permit functional alternatives that meet the same electrical and mechanical specifications. Substitute parts must maintain compatibility across output voltage, current capacity, package form factor, and thermal operating range.

The XC6215B302GR-G qualifies as a parametric equivalent substitute based on matching all electrical output specifications, identical package form factor, and equivalent compliance certifications. Variations in quiescent current and voltage dropout characteristics remain within acceptable tolerance for functional substitution in applications where the primary part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (XC6501D301GR-G): The XC6501D301GR-G remains the preferred selection when available. This part is in active production status with established supply inventory of 904 units. The device carries full ROHS3 compliance and REACH unaffected certification, meeting all regulatory requirements for commercial and industrial applications. The specified voltage dropout of 0.36V @ 200mA provides optimal efficiency in power-constrained designs.

Substitute Part Selection (XC6215B302GR-G): The XC6215B302GR-G is qualified as a direct substitute when the primary part experiences supply unavailability. This part maintains identical output voltage, current capacity, package form factor, and operating temperature specifications. The substitute carries equivalent ROHS3 and REACH compliance certifications. Current inventory of 28,192 units indicates superior supply availability.

Functional Differences: The XC6215B302GR-G exhibits lower quiescent current consumption (1.5 µA versus 20 µA), which provides improved standby power efficiency. The voltage dropout specification of 0.42V @ 100mA represents a marginal increase compared to the primary part's 0.36V @ 200mA specification. Both devices maintain identical enable control and over-current protection functionality.

Compliance and Regulatory Status: Both parts satisfy ROHS3 compliance requirements and carry REACH unaffected status, permitting unrestricted use in regulated markets. Both devices are classified under EAR99 export control and HTSUS code 8542.39.0001, maintaining equivalent trade compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can the XC6215B302GR-G be used as a direct replacement for the XC6501D301GR-G in existing designs?

A: Yes. Both devices deliver identical 3V fixed output at 200mA maximum current, operate across the same -40°C to 85°C temperature range, and utilize the identical 4-UDFN Exposed Pad package (1.2x1.6mm). Enable control and over-current protection features are present on both parts. No circuit modifications are required for substitution.

Q: What are the differences in voltage dropout between these two parts?

A: The XC6501D301GR-G specifies 0.36V maximum dropout at 200mA output current. The XC6215B302GR-G specifies 0.42V maximum dropout at 100mA output current. The dropout difference is 0.06V at the 100mA measurement point. In applications operating at full 200mA load, the primary part provides superior efficiency. For applications operating below 100mA, the substitute part may exhibit comparable or superior performance due to its lower quiescent current.

Q: How do the quiescent current specifications affect circuit design?

A: The XC6501D301GR-G draws 20 µA quiescent current during normal operation. The XC6215B302GR-G draws 1.5 µA quiescent current, representing a 13.3x reduction in standby power consumption. For battery-powered or low-power standby applications, the substitute part provides significant power efficiency advantages. For continuously powered applications, this difference has minimal impact on overall system power budget.

Q: Are both parts available in the same packaging format?

A: Yes. Both the XC6501D301GR-G and XC6215B302GR-G are supplied in 4-UDFN Exposed Pad packages with identical 1.2x1.6mm physical dimensions. Both are available in Tape & Reel (TR) format for automated assembly. PCB layout and reflow soldering profiles remain identical between parts.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts carry ROHS3 compliance certification and REACH unaffected status. Both are classified under EAR99 export control and HTSUS code 8542.39.0001. Moisture Sensitivity Level (MSL) is rated as 1 (Unlimited) for both devices. No compliance differences exist between the primary and substitute parts.

Q: What is the current inventory status for each part?

A: The XC6501D301GR-G has 904 units in stock. The XC6215B302GR-G has 28,192 units in stock, indicating significantly higher supply availability. When lead time or supply constraints affect the primary part, the substitute part offers improved procurement reliability.

Q: Can the enable control feature be used identically on both parts?

A: Yes. Both devices incorporate enable control functionality with identical operational characteristics. The enable pin operates in the same manner on both parts, permitting direct substitution in designs utilizing this feature for power sequencing or shutdown control.

Q: Are there any PSRR (Power Supply Rejection Ratio) differences between these parts?

A: The XC6501D301GR-G specifies PSRR of 50dB at 1kHz. The XC6215B302GR-G does not provide a published PSRR specification. For applications requiring documented PSRR performance, the primary part provides specified performance data. For general-purpose voltage regulation applications, this difference does not affect functional compatibility.
