L6718 Equivalent & Substitute Parts

Part Overview

The L6718 is an Intel VR12 Voltage Regulator Controller IC manufactured by STMicroelectronics, designed for dual-output power management applications. This component operates with input voltage range of 4.75V to 7.5V and supports output voltages from 0.25V to 2.145V. The L6718 is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the L6718 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Manufacturer: STMicroelectronics (same manufacturer ensures design continuity and support)
• Category: Power Management (PMIC) (same functional classification)
• Voltage Regulator Controller Architecture: VR-series controllers (VR12 or VR13 variants)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, MSL 3 (168 Hours)
• Surface Mount Technology: VFQFPN package family

The substitute parts identified operate within the same regulatory and environmental specifications as the L6718, ensuring compliance with manufacturing standards and operational requirements. Package variations (40VFQFPN and 48VFQFPN) represent different pin configurations within the same VFQFN family, suitable for alternative circuit topologies while maintaining core controller functionality.

Parameter Comparison

Engineering Selection Recommendations

PM6773TR Selection Criteria: The PM6773TR operates as an active product with VR13 controller architecture in a 40-VFQFPN package. This substitute maintains full ROHS3 compliance and identical MSL specifications. Selection of PM6773TR is appropriate for applications where the 40-pin configuration aligns with circuit board layout requirements and pin assignment compatibility.

PM6776TR Selection Criteria: The PM6776TR operates as an active product with VR13 controller architecture in a 48-VFQFPN package. This substitute maintains full ROHS3 compliance and identical MSL specifications. Selection of PM6776TR is appropriate for applications requiring the 48-pin configuration and corresponding pin assignments.

Compliance Assurance: Both substitute parts maintain identical regulatory status to the L6718: ROHS3 Compliant, REACH Unaffected, and EAR99 export classification. Moisture sensitivity levels and handling requirements remain consistent across all three components, eliminating changes to storage and assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can PM6773TR or PM6776TR directly replace L6718 in existing designs? A: Direct replacement requires verification of pin assignment compatibility and circuit board layout accommodation. The substitute parts operate within the same regulatory framework and environmental specifications as the L6718, but package pin counts differ (40 and 48 pins versus 56 pins). Circuit schematic and PCB layout review is necessary to confirm functional equivalence.

Q: What is the primary difference between PM6773TR and PM6776TR? A: The primary difference is package pin count: PM6773TR uses 40-VFQFPN packaging while PM6776TR uses 48-VFQFPN packaging. Both maintain identical compliance certifications and moisture sensitivity levels. Selection between these two depends on specific circuit requirements and available pin configurations needed for the application.

Q: Are there any differences in handling or storage requirements between L6718 and the substitute parts? A: No. All three components share identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours), requiring the same storage conditions, handling procedures, and reflow soldering parameters. No changes to manufacturing processes are necessary when transitioning between these parts.

Q: Why is the L6718 listed as obsolete? A: The L6718 is classified as obsolete by the manufacturer. The active substitute parts (PM6773TR and PM6776TR) represent current production alternatives that maintain compatibility with the same regulatory standards and environmental specifications.

Q: What regulatory certifications apply to all three components? A: All three components are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. These certifications ensure compliance with environmental regulations and export requirements across all substitute options.
