Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XC6121F528ER-G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Single-channel voltage monitoring capability
• 2.8V voltage threshold setting
• Open Drain or Open Collector output configuration
• Active Low reset logic
• 400ms typical reset timeout duration
• Operating temperature range of -40°C to 85°C

Mechanical & Physical Equivalence Criteria:

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

Compliance & Regulatory Equivalence:

• ROHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level 1 (Unlimited)

The XC6123C528ER-G qualifies as a parametric equivalent substitute because it maintains identical electrical specifications, mechanical packaging, and regulatory compliance across all critical parameters. The primary distinction between the main part and substitute lies in the base product number series (XC6121 versus XC6123), which does not affect functional compatibility within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (XC6121F528ER-G): The XC6121F528ER-G is the specified component with higher inventory availability (872 units). This part maintains active product status and full compliance with ROHS3 and REACH regulatory requirements. Selection of this part is appropriate for standard procurement and design implementation.

Substitute Part Selection (XC6123C528ER-G): The XC6123C528ER-G qualifies as a direct parametric equivalent with identical electrical and mechanical specifications. This substitute part is suitable for implementation when primary part availability is constrained. The substitute maintains equivalent product status, regulatory compliance, and operational characteristics across all specified parameters. Inventory availability for the substitute is 784 units.

Compliance Considerations: Both parts satisfy ROHS3 compliance requirements and maintain REACH Unaffected status, ensuring regulatory compatibility across standard industrial and commercial applications. Moisture Sensitivity Level 1 (Unlimited) classification applies to both parts, indicating no moisture-related handling restrictions during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can XC6123C528ER-G be used as a direct replacement for XC6121F528ER-G in existing designs?

A: Yes. The XC6123C528ER-G is a parametric equivalent substitute with identical electrical specifications, mechanical packaging, and regulatory compliance. All critical parameters including voltage threshold (2.8V), reset logic (Active Low), reset timeout (400ms typical), output configuration (Open Drain or Open Collector), and operating temperature range (-40°C to 85°C) are identical. The component can be substituted without design modification.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 6-UFDFN Exposed Pad package type with 6-USPC (1.8x2) supplier device package dimensions. Mechanical compatibility is complete, and both parts are supplied in Tape & Reel (TR) format for surface mount assembly.

Q: What determines whether a part qualifies as an equivalent substitute?

A: Substitution eligibility is based on strict equivalence across electrical parameters (voltage threshold, output configuration, reset logic, timeout duration, temperature range), mechanical parameters (package type, dimensions, mounting method), and regulatory compliance (RoHS status, REACH status, MSL rating). All these parameters must match exactly between the main part and substitute.

Q: Do both parts have the same regulatory compliance status?

A: Yes. Both XC6121F528ER-G and XC6123C528ER-G are ROHS3 Compliant, REACH Unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). Regulatory compatibility is complete.

Q: What is the difference between the XC6121 and XC6123 base product series?

A: The base product number series designation (XC6121 versus XC6123) does not affect functional compatibility or electrical performance within the specified application envelope. Both series maintain identical specifications for the 2.8V threshold watchdog circuit configuration.

Q: Are both parts currently in active production status?

A: Yes. Both XC6121F528ER-G and XC6123C528ER-G maintain active product status with current inventory availability (872 units and 784 units respectively).
