Substitute Part Grouping Explanation

Substitute parts for the XC6221C1027R-G are determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Fixed output voltage: 1V
• Output current rating: 200mA
• Maximum input voltage: 6V
• Voltage dropout: 0.65V @ 100mA
• Control features: Enable function
• Protection features: Over Current protection
• PSRR: 70dB (1kHz)
• Operating temperature range: -40°C ~ 85°C

Mechanical Equivalence Criteria:

• Package type: 4-XDFN (4-USPN 0.90x1.2)
• Mounting type: Surface Mount
• Tape & Reel packaging

Compliance Equivalence Criteria:

• RoHS3 Compliant
• MSL 1 (Unlimited)
• REACH Unaffected
• ECCN: EAR99

The XC6221C1027R-G has two parametric equivalents: XC6217C1027R-G and XC6217D1027R-G. Both parts share identical electrical output specifications, package dimensions, and compliance certifications. The primary difference between these substitutes lies in quiescent current specifications, which do not affect the core substitution relationship for applications requiring the specified 1V/200mA output.

Parameter Comparison

Engineering Selection Recommendations

All three parts—XC6221C1027R-G, XC6217C1027R-G, and XC6217D1027R-G—are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these equivalents is based on the following factors:

Primary Selection Criteria:

• All parts meet identical electrical output specifications (1V, 200mA)
• All parts are pin-compatible within the 4-USPN (0.90x1.2) package footprint
• All parts support the same operating temperature range (-40°C ~ 85°C)
• All parts include Enable control and Over Current protection

Inventory Availability:

• XC6217D1027R-G: 1035 units in stock (highest availability)
• XC6221C1027R-G: 945 units in stock
• XC6217C1027R-G: 755 units in stock (lowest availability)

Quiescent Current Consideration:

• XC6221C1027R-G: 50 µA quiescent current
• XC6217C1027R-G: 8 µA quiescent current
• XC6217D1027R-G: 8 µA quiescent current

The XC6217 series (both C and D variants) offer lower quiescent current specifications compared to the XC6221C1027R-G. For applications where standby power consumption is a design constraint, the XC6217 variants provide improved efficiency. For applications where quiescent current is not a limiting factor, all three parts are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can XC6217C1027R-G and XC6217D1027R-G be used interchangeably with XC6221C1027R-G?

A: Yes. Both XC6217 variants are parametric equivalents with identical output voltage (1V), output current (200mA), input voltage rating (6V), dropout voltage (0.65V @ 100mA), package type (4-USPN 0.90x1.2), and operating temperature range (-40°C ~ 85°C). All three parts are pin-compatible and functionally equivalent for applications requiring these specifications.

Q: What is the difference between XC6217C1027R-G and XC6217D1027R-G?

A: Both XC6217C1027R-G and XC6217D1027R-G share identical electrical output specifications and package dimensions. The primary difference is in the base product number designation (C versus D variant). Both parts have 8 µA quiescent current, compared to 50 µA for the XC6221C1027R-G.

Q: Are there any package or footprint differences between these parts?

A: No. All three parts use the identical 4-XDFN package with 4-USPN (0.90x1.2) dimensions. PCB footprints and land patterns are identical, allowing direct substitution without layout modifications.

Q: Which part should I select for lowest power consumption?

A: XC6217C1027R-G and XC6217D1027R-G both feature 8 µA quiescent current, compared to 50 µA for XC6221C1027R-G. For applications prioritizing standby power efficiency, either XC6217 variant is the appropriate selection.

Q: Are all three parts RoHS compliant?

A: Yes. XC6221C1027R-G, XC6217C1027R-G, and XC6217D1027R-G are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: Can I mix these parts in the same production batch?

A: Yes. All three parts are functionally equivalent with identical electrical specifications, package types, and compliance certifications. They can be used interchangeably in the same design and production environment.
