Substitute Part Grouping Explanation

Substitution eligibility for the XC6121F628ER-G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Single-channel voltage monitoring functionality
• 2.8V voltage threshold setting
• Open Drain or Open Collector output configuration
• Active Low reset logic
• 1.6s typical reset timeout duration
• Operating temperature range of -40°C to 85°C

Mechanical Equivalence Criteria:

• 6-UFDFN Exposed Pad package type
• 6-USPC (1.8x2) supplier device package
• Surface mount mounting type
• Tape & Reel packaging format

Regulatory & Compliance Equivalence:

• ROHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level 1 classification

The XC6122E628ER-G qualifies as a parametric equivalent substitute because it maintains identical electrical specifications, mechanical dimensions, and regulatory compliance across all specified parameters.
