Substitute Part Grouping Explanation

Substitute parts for the XC6808A3C18R-G are identified based on strict parameter equivalence within the XC680x series. The substitution criteria are defined by the following parameters that must remain constant across all equivalent parts:

Critical Equivalence Parameters:

• 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
• Current - Charging: Constant - Programmable
• Programmable Features: Current
• Fault Protection: Over Current, Over Temperature, Reverse Current
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical specifications and mechanical packaging, ensuring direct functional interchangeability within the same circuit application.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status with full regulatory compliance. The XC6808A3C18R-G and its substitute equivalents (XC6808A3C28R-G, XC6808A4C38R-G, XC6808A4C48R-G, XC6808B4C28R-G) are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

Selection between equivalent parts should be based on inventory availability and supply chain considerations. All parts share identical electrical performance characteristics, mechanical packaging dimensions, and thermal operating ranges. The 6-USP-B07 (1.8x2) package format ensures PCB layout compatibility across all substitutes.

Frequently Asked Questions (FAQ)

Q: Can XC6808A3C28R-G replace XC6808A3C18R-G in an existing design?

A: Yes. Both parts maintain identical electrical specifications including 40mA maximum charge current, 4.2V battery pack voltage, 6V maximum supply voltage, and -40°C to 85°C operating temperature range. The 6-XDFN Exposed Pad package and 6-USP-B07 (1.8x2) supplier package are identical, ensuring direct PCB compatibility.

Q: What are the key parameters that define substitutability for XC6808 series charger ICs?

A: Substitutability is determined by: battery chemistry (Lithium Ion/Polymer), single-cell configuration, 40mA maximum charge current, 4.2V battery pack voltage, 6V maximum supply voltage, operating temperature range (-40°C to 85°C), package type (6-XDFN Exposed Pad), and fault protection features (Over Current, Over Temperature, Reverse Current).
