XC6121F616ER-G Equivalent & Substitute Parts

Part Overview

The XC6121F616ER-G is a single-channel supervisor integrated circuit manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This watchdog circuit monitors voltage levels and provides active-low reset output through an open-drain or open-collector configuration. The device operates across the industrial temperature range of -40°C to 85°C and is housed in a 6-UFDFN package with exposed pad.

The XC6121F616ER-G maintains Active product status with 984 units currently in stock. Equivalent substitute parts are identified based on matching electrical specifications, mechanical compatibility, and compliance certifications. Substitutes enable design flexibility, inventory optimization, and supply chain continuity when the primary part number becomes unavailable.

Substitute Part Grouping Explanation

Substitute parts for the XC6121F616ER-G are identified as parametric equivalents within the XC6121 base product family. Substitution eligibility is determined by strict matching of the following critical parameters:

Electrical Specifications:

• Single-channel voltage monitoring at 1.6V threshold
• Open-drain or open-collector output configuration
• Active-low reset logic with 1.6s typical timeout
• Operating temperature range: -40°C to 85°C

Mechanical & Package Specifications:

• 6-UFDFN package with exposed pad
• 6-USPC (1.8x2) supplier device package
• Surface mount mounting type

Compliance & Regulatory:

• ROHS3 compliance
• REACH unaffected status
• MSL Level 1 (unlimited moisture sensitivity)
• EAR99 export classification

All substitute parts maintain identical functional behavior, thermal performance, and regulatory compliance. Differences exist only in manufacturing process variants or internal circuit topology that do not affect external electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—XC6121F616ER-G, XC6121D616ER-G, and XC6121E616ER-G—are functionally equivalent and interchangeable for applications requiring single-channel voltage supervision at 1.6V threshold with active-low reset output.

Selection Criteria Based on Provided Data:

Product Status: All three parts maintain Active status, confirming ongoing manufacturer support and availability.

Compliance Certifications: All parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial and consumer applications.

Regulatory Classification: All parts carry EAR99 export classification and 8542.39.0001 HTSUS code, indicating identical trade and export compliance.

Inventory Availability: XC6121E616ER-G offers the highest current stock level at 3440 units, followed by XC6121F616ER-G at 984 units, and XC6121D616ER-G at 779 units. Inventory levels support supply chain planning and lead-time optimization.

Moisture Sensitivity: All parts are classified as MSL Level 1 (Unlimited), requiring no special moisture control during storage, handling, or assembly.

Selection between these equivalents is determined by inventory availability, delivery schedule requirements, and supply chain logistics rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Are XC6121D616ER-G and XC6121E616ER-G direct replacements for XC6121F616ER-G?

A: Yes. All three part numbers are parametric equivalents with identical electrical specifications, package dimensions, and compliance certifications.
