• 1.6V voltage threshold specification
• 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
• 6-UFDFN exposed pad package with 1.8x2mm dimensions
• Surface mount configuration
• Tape & Reel packaging format

Compliance Alignment:

• ROHS3 compliance status
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected classification
• EAR99 ECCN designation
• HTSUS code 8542.39.0001

The XC6121D616ER-G and XC6121E616ER-G are parametric equivalents that satisfy all electrical and mechanical requirements for direct substitution with the XC6124C616ER-G. Both substitute parts are manufactured by Torex Semiconductor Ltd and maintain identical functional specifications, package geometry, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

All three supervisor IC components—XC6124C616ER-G, XC6121D616ER-G, and XC6121E616ER-G—are manufactured by Torex Semiconductor Ltd and maintain Active product status. Each component satisfies identical electrical specifications, mechanical package requirements, and regulatory compliance standards.

Compliance Status: All parts are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control. Moisture sensitivity level 1 (Unlimited) applies uniformly across all three components, indicating no special handling or storage requirements beyond standard electronic component practices.

Inventory Availability: The XC6121E616ER-G offers the highest current inventory level at 3440 units, followed by the XC6124C616ER-G at 851 units and the XC6121D616ER-G at 779 units. Component selection may be influenced by supply chain requirements and procurement timelines.

Functional Equivalence: Direct substitution between these components is supported by complete parameter alignment across all critical electrical and mechanical specifications. No design modifications, PCB layout adjustments, or firmware changes are required when transitioning between these supervisor IC options.

Frequently Asked Questions (FAQ)

Q: Can the XC6121D616ER-G or XC6121E616ER-G be used as direct replacements for the XC6124C616ER-G?

A: Yes. Both the XC6121D616ER-G and XC6121E616ER-G are parametric equivalents that match all electrical specifications, output configuration, reset timing, voltage threshold, and package geometry of the XC6124C616ER-G. Direct substitution is supported without design changes.

Q: Are there any differences in the 6-UFDFN package dimensions between these parts?

A: No. All three components use the identical 6-UFDFN exposed pad package with 1.8x2mm dimensions and 6-USPC supplier device package designation. PCB footprints and land patterns are interchangeable.

Q: Do these supervisor ICs require different handling or storage procedures?

A: No. All three components share Moisture Sensitivity Level 1 (Unlimited), indicating identical handling and storage requirements. Standard electronic component storage practices apply uniformly across all three parts.

Q: What is the significance of the different base product numbers (XC6124 versus XC6121)?

A: The base product number designates the internal product line within Torex Semiconductor Ltd's supervisor IC portfolio. Despite different base numbers, the XC6121D616ER-G and XC6121E616ER-G maintain complete electrical and mechanical equivalence with the XC6124C616ER-G for this specific application.

Q: Are all three parts ROHS3 compliant and REACH unaffected?

A: Yes. The XC6124C616ER-G, XC6121D616ER-G, and XC6121E616ER-G are all ROHS3 compliant and REACH unaffected. Regulatory compliance status is identical across all three components.

Q: Which part should be selected based on current inventory levels?

A: The XC6121E616ER-G offers the highest inventory availability at 3440 units. Selection based on inventory should consider procurement lead times and supply chain continuity requirements. All three parts are functionally equivalent for design purposes.

Q: Is the 1.6V voltage threshold specification identical across all three supervisor ICs?

A: Yes. The voltage threshold specification of 1.6V is identical for the XC6124C616ER-G, XC6121D616ER-G, and XC6121E616ER-G. Reset timeout duration of 1.6s typical and active low reset logic are also uniform across all three components.
