Key Parameters

Substitute Part Grouping Explanation

All substitute parts listed are parametric equivalents within the Torex XC680x series. Substitution eligibility is determined by the following critical parameters that remain constant across all equivalent parts:

Electrical Specifications:

• Battery chemistry: Lithium Ion/Polymer
• Single-cell configuration
• Maximum charging current: 40mA
• Battery pack voltage: 4.2V
• Maximum supply voltage: 6V
• Programmable charging current feature
• Identical fault protection: Over Current, Over Temperature, Reverse Current

Mechanical & Package Specifications:

• Package type: 6-XDFN Exposed Pad
• Supplier device package: 6-USP-B07 (1.8x2)
• Surface mount mounting type
• Operating temperature range: -40°C ~ 85°C

Compliance & Regulatory:

• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level 1 (Unlimited)

The substitute parts XC6808A3C28R-G, XC6808A4C38R-G, XC6808A4C48R-G, and XC6808B4C28R-G are direct functional equivalents to the XC6808B2C48R-G and can be used interchangeably in circuit designs without modification to PCB layout or electrical connections.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are Active products from Torex Semiconductor Ltd and maintain full compliance with RoHS3 and REACH regulations. Selection among the equivalent parts should be based on inventory availability and supply chain requirements, as all parts satisfy identical electrical and mechanical specifications for single-cell lithium ion/polymer battery charging applications.

The XC6808A4C48R-G currently maintains the highest inventory level at 1085 pieces, followed by XC6808B4C28R-G at 1079 pieces. The XC6808B2C48R-G (primary part) has 930 pieces in stock. All parts are supplied in Tape & Reel packaging with MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

For applications requiring immediate component availability, XC6808A4C48R-G or XC6808B4C28R-G are suitable alternatives. For long-term supply chain planning, all five part numbers within this equivalency group are equally viable, as they share identical performance characteristics and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can XC6808A3C28R-G be used as a direct replacement for XC6808B2C48R-G?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (40mA maximum charging current, 4.2V battery voltage, 6V maximum supply voltage), identical package type (6-XDFN Exposed Pad, 6-USP-B07 1.8x2), and identical operating temperature range (-40°C to 85°C). No circuit modifications are required.

Q: Are there any differences in fault protection between the substitute parts?

A: No. All substitute parts provide identical fault protection: Over Current, Over Temperature, and Reverse Current protection. The protection architecture and thresholds are equivalent across all parts in this group.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All parts, including XC6808B2C48R-G and its substitutes, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply.

Q: Can these parts be mixed in the same production batch?

A: Yes. All parts are surface mount components in identical 6-XDFN packages with the same pinout and electrical characteristics. PCB layout and reflow profiles remain unchanged when substituting between any parts in this equivalency group.

Q: What is the basis for substitution eligibility among these parts?

A: Substitution is based on matching all critical parameters: battery chemistry (Lithium Ion/Polymer), cell count (1), maximum charging current (40mA), battery voltage (4.2V), supply voltage (6V), package type (6-XDFN Exposed Pad), mounting type (Surface Mount), operating temperature range (-40°C to 85°C), and regulatory compliance (RoHS3, REACH Unaffected).

Q: Are there any programming or configuration differences between substitute parts?

A: No. All parts feature programmable charging current with identical control interfaces. Configuration methods and register settings are equivalent across all substitute parts.

Q: Which substitute part should be selected for new designs?

A: Any of the four substitute parts (XC6808A3C28R-G, XC6808A4C38R-G, XC6808A4C48R-G, XC6808B4C28R-G) are suitable for new designs. Selection should be based on current inventory availability and supplier lead times, as all parts are Active products with identical performance and compliance characteristics.
