Substitute Part Grouping Explanation

Substitute parts for the XC6220D301ER-G are identified based on strict electrical and mechanical parameter matching within the Torex XC6220 series. The substitution criteria are:

Critical Parameters for Substitution:

• Output voltage configuration: Positive fixed 3V output
• Output current rating: 1A maximum
• Input voltage maximum: 6V
• Package type: 6-USPC (1.8x2) surface mount
• Voltage dropout specification: 0.655V @ 1A
• Operating temperature range: -40°C ~ 85°C
• Protection features: Over Current and Over Temperature
• Control features: Enable function

The XC6220B301ER-G qualifies as a parametric equivalent within this product category. Both parts share identical electrical output specifications, input voltage ratings, package dimensions, and thermal operating ranges. Differences in quiescent current and supply current specifications do not disqualify substitution when the primary functional requirements are met.

Parameter Comparison

Engineering Selection Recommendations

XC6220D301ER-G (Primary Part): The XC6220D301ER-G is the specified component with active product status and established supply chain availability (891 pieces in stock). This part meets all ROHS3 compliance requirements and REACH regulatory standards. Selection of this part is appropriate when primary sourcing is available and design schedules permit standard lead times.

XC6220B301ER-G (Substitute Part): The XC6220B301ER-G is a direct parametric equivalent with identical electrical output specifications, input voltage ratings, package configuration, and thermal operating range. This substitute part is suitable for applications where the primary part experiences supply constraints or extended lead times. The XC6220B301ER-G demonstrates improved quiescent current performance (18 µA versus 28 µA) and lower maximum supply current (108 µA versus 118 µA), which may provide marginal power efficiency benefits in battery-powered or low-power applications. Both parts maintain identical ROHS3 compliance and REACH unaffected status. Inventory availability for the substitute is higher (1254 pieces), supporting rapid procurement when needed.

Frequently Asked Questions (FAQ)

Q: Can XC6220B301ER-G be used as a direct replacement for XC6220D301ER-G in existing designs?

A: Yes. Both parts deliver identical fixed 3V output at 1A maximum current, operate across the same -40°C to 85°C temperature range, and use the same 6-USPC (1.8x2) surface mount package. Electrical performance specifications including voltage dropout (0.655V @ 1A), PSRR (50dB at 1kHz), and protection features are identical. PCB layout and component placement require no modification.

Q: What are the differences between these two parts?

A: The primary differences are in quiescent current and supply current specifications. XC6220B301ER-G operates at 18 µA quiescent current compared to 28 µA for XC6220D301ER-G, and maximum supply current is 108 µA versus 118 µA. These differences do not affect functional compatibility or output voltage regulation performance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both XC6220D301ER-G and XC6220B301ER-G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the package configuration for these parts?

A: Both parts use a 6-UFDFN Exposed Pad package with supplier device package designation 6-USPC (1.8x2). This is a compact surface mount package measuring 1.8mm by 2mm, suitable for space-constrained applications.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts are rated for operation across the full -40°C to 85°C temperature range and include over-temperature protection features. No thermal derating is required within this specified operating range.

Q: What protection features are included in both parts?

A: Both XC6220D301ER-G and XC6220B301ER-G include over-current protection and over-temperature protection. Both parts feature an enable control function for output regulation control.
