Key Parameters

Substitute Part Grouping Explanation

Substitution of the WM8310CGEB/V is determined by the following critical parameters:

• Functional Category: Power Management (PMIC) for handheld/mobile device applications
• Supply Voltage Range: 2.7V ~ 5.5V compatibility
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount technology
• Regulatory Compliance: REACH Unaffected, ECCN EAR99 classification

The LTC3586EUFE#PBF from Analog Devices Inc. meets these substitution criteria. Both components operate within identical supply voltage and temperature specifications, serve equivalent power management functions in mobile device applications, and maintain compatible regulatory and compliance status. The substitute part is classified as active product status with improved moisture sensitivity characteristics (MSL 1 vs. MSL 3).

Parameter Comparison

Engineering Selection Recommendations

The LTC3586EUFE#PBF is the designated equivalent substitute for the obsolete WM8310CGEB/V. Selection of this substitute is supported by:

• Functional Equivalence: Both components are PMICs designed for handheld and mobile device power management with identical supply voltage specifications (2.7V ~ 5.5V)
• Thermal Compatibility: Operating temperature range of -40°C ~ 85°C is maintained across both parts
• Regulatory Alignment: Both components maintain REACH Unaffected status and EAR99 ECCN classification
• Product Availability: The substitute part maintains active product status with current inventory availability, addressing the obsolescence of the original component
• Compliance Enhancement: The substitute part offers improved moisture sensitivity characteristics (MSL 1 vs. MSL 3), providing superior handling and storage reliability

Frequently Asked Questions (FAQ)

Q: Can the LTC3586EUFE#PBF directly replace the WM8310CGEB/V in existing designs?

A: The LTC3586EUFE#PBF meets the core electrical and thermal specifications of the WM8310CGEB/V. However, package differences exist: the original uses 169-TFBGA while the substitute uses 38-WFQFN. PCB layout modifications are required for physical implementation.

Q: What are the key differences between these two PMIC components?

A: The primary differences are package type, manufacturer, and product status. Both maintain identical supply voltage (2.7V ~ 5.5V) and operating temperature (-40°C ~ 85°C) specifications. The substitute offers improved moisture sensitivity (MSL 1 vs. MSL 3) and active product status.

Q: Why is the WM8310CGEB/V classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by Cirrus Logic Inc. The LTC3586EUFE#PBF from Analog Devices Inc. provides functional equivalence with active product support.

Q: Are there regulatory or compliance concerns with substitution?

A: Both components maintain identical regulatory status: REACH Unaffected and EAR99 ECCN classification. No compliance barriers exist for substitution.

Q: What packaging considerations apply to this substitution?

A: The WM8310CGEB/V uses 169-TFBGA packaging while the LTC3586EUFE#PBF uses 38-WFQFN packaging. These are fundamentally different package types requiring complete PCB redesign for physical implementation.
