XC6808B2D38R-G Equivalent & Substitute Parts

Part Overview

The XC6808B2D38R-G is a single-cell lithium ion/polymer battery charger IC manufactured by Torex Semiconductor Ltd. This power management integrated circuit operates in the 6-USP-B07 (1.8x2) surface mount package and is classified as an active product with full RoHS3 compliance. The device provides constant-current programmable charging with integrated fault protection for over-current, over-temperature, and reverse-current conditions. Substitute parts are identified when equivalent electrical specifications, package configurations, and operational parameters are maintained across the XC680x series.

Substitute Part Grouping Explanation

Substitute parts within the XC680x series are identified based on strict parametric equivalence. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Battery chemistry (Lithium Ion/Polymer)
• Number of cells (1 cell)
• Maximum charge current (40mA)
• Battery pack voltage (4.35V)
• Maximum supply voltage (6V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (6-XDFN Exposed Pad)
• Supplier device package (6-USP-B07 1.8x2)
• Fault protection features (Over Current, Over Temperature, Reverse Current)
• Programmable features (Current)
• Mounting type (Surface Mount)
• Compliance certifications (RoHS3, REACH Unaffected)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Variations in part number suffix indicate different internal programming or trim configurations that do not affect the core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6808B2D38R-G and XC6808AND18R-G are active products from Torex Semiconductor Ltd with identical electrical specifications, package configurations, and compliance certifications. Selection between these parts is based on availability and inventory status. The XC6808AND18R-G currently maintains higher inventory levels (815 Pcs) compared to the XC6808B2D38R-G (672 Pcs), both supplied as new original components in tape and reel packaging.

Both parts satisfy RoHS3 compliance requirements and REACH unaffected status, making them suitable for applications requiring environmental regulatory adherence. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can XC6808AND18R-G be used as a direct replacement for XC6808B2D38R-G?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, package types, and operational characteristics. All critical parameters including charge current, battery voltage, supply voltage, temperature range, and fault protection features are matched.

Q: What is the difference between the two part numbers?

A: The suffix variation (B2D38R versus AND18R) indicates different internal programming or trim configurations within the XC680x series. These differences do not affect the core electrical performance or mechanical compatibility.

Q: Are the packages physically identical?

A: Yes. Both parts use the 6-XDFN Exposed Pad package in the 6-USP-B07 (1.8x2) configuration. They are pin-compatible and have identical footprints for surface mount assembly.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). They meet identical environmental and regulatory requirements.

Q: What are the key parameters that must match for substitution?

A: Critical matching parameters include battery chemistry (Lithium Ion/Polymer), single-cell configuration, 40mA maximum charge current, 4.35V battery pack voltage, 6V maximum supply voltage, -40°C to 85°C operating temperature range, 6-XDFN package type, and integrated fault protection features (over-current, over-temperature, reverse-current).

Q: Can these parts be used in applications requiring different charge currents?

A: No. Both parts are specified for 40mA maximum charge current. Applications requiring different charge current specifications require alternative part numbers from the XC680x series with different current ratings.

Q: Is there a preference between the two parts for new designs?

A: Selection is based on availability and supply chain requirements. Both parts are active products with identical specifications and are suitable for new designs. Inventory availability may influence procurement decisions.
