Substitute Part Grouping Explanation

All substitute parts listed for the XC6808B2C18R-G are parametric equivalents within the XC680x series. Substitution is based on identical electrical and mechanical specifications across the following critical parameters:

Substitution Criteria:

• Battery Chemistry: Lithium Ion/Polymer
• Number of Cells: 1
• Charge Current - Max: 40mA
• Battery Pack Voltage: 4.2V
• Voltage - Supply (Max): 6V
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package / Case: 6-XDFN Exposed Pad
• Supplier Device Package: 6-USP-B07 (1.8x2)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute parts differ only in internal programming or configuration codes embedded within their part numbers, which do not affect the core electrical performance or physical compatibility. All parts share identical fault protection features (Over Current, Over Temperature, Reverse Current) and programmable current charging capability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active products from Torex Semiconductor Ltd and maintain full compliance with RoHS3 and REACH regulations. Each part carries Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

1. Inventory Availability: XC6808A4C48R-G (1085 Pcs) and XC6808B4C28R-G (1079 Pcs) offer the highest stock levels for immediate procurement.

2. Regulatory Compliance: All parts meet identical compliance standards and are suitable for applications requiring RoHS3 and REACH certification.

3. Physical Compatibility: All parts use the 6-USP-B07 (1.8x2) package footprint and are compatible with existing PCB layouts designed for the XC6808B2C18R-G.

4. Electrical Equivalence: No functional differences exist between the main part and substitutes across all specified electrical parameters, fault protection features, and operating conditions.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically identical to the XC6808B2C18R-G?

A: Yes. All substitute parts share identical electrical specifications including maximum charge current (40mA), battery pack voltage (4.2V), maximum supply voltage (6V), operating temperature range (-40°C ~ 85°C), and fault protection features (Over Current, Over Temperature, Reverse Current).

Q: Can I use these substitute parts on a PCB designed for the XC6808B2C18R-G without layout modifications?

A: Yes. All substitute parts use the identical 6-XDFN Exposed Pad package with the 6-USP-B07 (1.8x2) footprint. No PCB layout changes are required.

Q: Do the substitute parts require different handling or storage procedures?

A: No. All parts carry Moisture Sensitivity Level 1 (Unlimited), which is the lowest sensitivity classification. Standard component storage and handling procedures apply equally to all parts in this group.

Q: What is the difference between the part numbers if the electrical specifications are identical?

A: The differences in part numbers reflect internal programming or configuration codes assigned by Torex Semiconductor Ltd. These variations do not affect the core electrical performance, physical compatibility, or functional behavior of the charger IC.

Q: Are all substitute parts compliant with the same regulatory standards?

A: Yes. All parts are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements for use in consumer and industrial applications.

Q: Which substitute part should I select if multiple are available?

A: Selection should be based on inventory availability and procurement lead times. XC6808A4C48R-G and XC6808B4C28R-G offer the highest stock levels. All parts are functionally equivalent and suitable for direct substitution.
