XC6123C628ER-G Equivalent & Substitute Parts

Part Overview

The XC6123C628ER-G is a single-channel supervisor integrated circuit manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This watchdog circuit monitors a single voltage threshold at 2.8V and provides active-low reset output through an open-drain or open-collector configuration. The device is currently in active product status with 901 units in stock. Substitute parts are identified when equivalent electrical parameters, mechanical packaging, and compliance certifications align with the original specification, enabling direct replacement in applications where component availability or supply chain requirements necessitate alternative sourcing.

Substitute Part Grouping Explanation

Substitute parts for the XC6123C628ER-G are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Single voltage monitoring channel
• 2.8V threshold voltage
• Open-drain or open-collector output configuration
• Active-low reset logic
• 1.6s typical reset timeout
• Operating temperature range: -40°C to 85°C

Mechanical & Packaging Equivalence Criteria:

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

Compliance & Regulatory Equivalence Criteria:

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

Parts meeting all three equivalence categories are classified as parametric equivalents and direct substitutes. The XC6122E628ER-G satisfies all specified criteria and is therefore a valid substitute for the XC6123C628ER-G.

Parameter Comparison

Engineering Selection Recommendations

The XC6122E628ER-G is a direct parametric equivalent to the XC6123C628ER-G. Both devices are manufactured by Torex Semiconductor Ltd and share identical electrical specifications, mechanical packaging, and regulatory compliance certifications. Selection between these parts should be based on:

Availability & Lead Time: The XC6123C628ER-G maintains higher inventory (901 units) compared to the XC6122E628ER-G (812 units). If immediate availability is critical, the main part number is preferred.

Supply Chain Continuity: Both parts carry active product status, ensuring long-term availability and continued manufacturer support. Either part is suitable for new designs or production runs.

Compliance Requirements: Both parts satisfy ROHS3 compliance and REACH unaffected status, making them interchangeable for applications subject to environmental and regulatory restrictions.

Cost Optimization: When the XC6123C628ER-G experiences supply constraints or extended lead times, the XC6122E628ER-G provides equivalent functionality without design modification or circuit re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the XC6122E628ER-G be used as a direct replacement for the XC6123C628ER-G without circuit modification?

A: Yes. The XC6122E628ER-G is a parametric equivalent with identical electrical specifications, output characteristics, and package dimensions. No circuit modification is required for direct substitution.

Q: Are the pin configurations identical between these two parts?

A: Both parts use the 6-UFDFN Exposed Pad package with 6-USPC (1.8x2) dimensions. Pin configuration and functionality are identical, enabling direct PCB-level replacement.

Q: What is the difference between the XC6123C628ER-G and XC6122E628ER-G part numbers?

A: The part numbers reflect different product lines within the Torex supervisor IC family (XC6123 vs. XC6122 base series). However, the specific variants designated by the "C628ER-G" and "E628ER-G" suffixes share all critical electrical and mechanical parameters specified in this reference.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry active product status, ROHS3 compliance, and REACH unaffected classification. Moisture Sensitivity Level 1 (Unlimited) indicates no moisture-related handling restrictions. Both are suitable for industrial and commercial applications within the specified operating temperature range of -40°C to 85°C.

Q: What is the reset timeout specification, and is it identical for both parts?

A: Both parts feature a 1.6s typical reset timeout with active-low reset logic. This parameter is identical and critical for watchdog circuit timing in system supervision applications.

Q: Can these parts be used interchangeably in existing production?

A: Yes. The XC6122E628ER-G can be substituted into existing production runs using the XC6123C628ER-G without design changes, re-layout, or re-qualification, provided inventory of the primary part is exhausted or lead times exceed acceptable thresholds.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Tape & Reel (TR) format, standard for surface-mount production environments. The 6-USPC (1.8x2) package dimensions are identical, ensuring compatibility with existing pick-and-place equipment and solder reflow processes.
