Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the XC6121C628ER-G are identified based on strict equivalence of the following critical parameters:

Electrical Parameters:

• Single voltage monitoring channel
• 2.8V threshold voltage
• 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 Parameters:

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

Compliance & Regulatory:

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

The XC6122E628ER-G qualifies as a parametric equivalent substitute because it maintains identical electrical specifications, mechanical packaging dimensions, and regulatory compliance certifications as the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6121C628ER-G and XC6122E628ER-G are active products from Torex Semiconductor Ltd with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and supply chain considerations. The XC6121C628ER-G currently maintains higher inventory (1,069 units) compared to the XC6122E628ER-G (812 units). Both parts are suitable for applications requiring single-channel voltage supervision with 2.8V threshold monitoring, active-low reset output, and operation across the -40°C to 85°C temperature range. The identical electrical and mechanical specifications ensure functional interchangeability in circuit designs. Surface mount assembly processes and PCB layouts designed for the 6-USPC (1.8x2) package accommodate either part without modification.

Frequently Asked Questions (FAQ)

Q: Can XC6122E628ER-G replace XC6121C628ER-G in existing designs?
