AP6508FE-13 Equivalent & Substitute Parts

Part Overview

The AP6508FE-13 is a switching regulator IC manufactured by Diodes Incorporated, designed for power management applications in a 14-UFDFN Exposed Pad package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain compatibility with the original electrical specifications and mechanical form factor constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP6508FE-13 is based on the following critical parameters:

• Product Category: Power Management (PMIC) - Switching Regulator IC
• Mounting Technology: Surface Mount
• Package Type: 14-pin DFN with Exposed Pad (mechanical compatibility required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification
• Moisture Sensitivity: MSL rating consideration for storage and handling

The RT7263BZQW qualifies as a substitute based on matching product category, surface mount technology, 14-pin DFN package configuration, and equivalent regulatory compliance status. Both components are designed for buck switching regulator applications with exposed pad thermal management.

Parameter Comparison

Engineering Selection Recommendations

The RT7263BZQW is an active product substitute for the obsolete AP6508FE-13. Both components meet ROHS3 compliance and REACH requirements, ensuring regulatory alignment for new designs and legacy system updates.

Key considerations for selection:

• Product Status: The RT7263BZQW maintains active manufacturing status, providing long-term availability and supply chain stability compared to the obsolete AP6508FE-13.
• Package Compatibility: Both devices use 14-pin DFN packages with exposed pads. Physical footprint verification is required, as UFDFN and WFDFN variants may have dimensional differences.
• Moisture Sensitivity: The RT7263BZQW has MSL 3 (168 Hours) versus MSL 1 (Unlimited) for the AP6508FE-13. This affects storage conditions and handling procedures.
• Regulatory Compliance: Both components carry identical ECCN (EAR99) and HTSUS classifications, maintaining export and import compliance.

Frequently Asked Questions (FAQ)

Q: Can the RT7263BZQW be used as a direct replacement for the AP6508FE-13?

A: The RT7263BZQW is functionally equivalent in product category and regulatory compliance. However, physical package dimensions (UFDFN vs. WFDFN) must be verified against PCB layout constraints before implementation. Electrical specifications of the RT7263BZQW should be cross-referenced with the original AP6508FE-13 datasheet to confirm application compatibility.

Q: What is the difference between UFDFN and WFDFN packages?

A: Both are 14-pin DFN packages with exposed pads. UFDFN and WFDFN designations indicate different manufacturers' package specifications. Physical dimensions, lead pitch, and thermal characteristics may vary. Consult manufacturer datasheets for precise footprint and thermal performance data.

Q: Does the MSL rating difference affect component selection?

A: Yes. The AP6508FE-13 has MSL 1 (Unlimited storage), while the RT7263BZQW has MSL 3 (168-hour limit). MSL 3 components require controlled storage conditions and have a 168-hour floor life after moisture exposure. This impacts procurement, inventory management, and manufacturing processes.

Q: Are both components RoHS3 compliant?

A: Yes. Both the AP6508FE-13 and RT7263BZQW are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What should be verified before implementing the RT7263BZQW?

A: Verify PCB footprint compatibility with the specific DFN package variant, confirm electrical operating parameters match application requirements, and validate thermal management characteristics for the target design. Consult both manufacturer datasheets for complete technical specifications.
