Key Parameters

Substitute Part Grouping Explanation

Substitution of the WM8912CGEFL/RV is based on strict equivalence of the following critical parameters:

• Number of Channels: 2 channels
• Resolution: 24 bits
• Sampling Rate: 96 kHz
• Data Interface: DSP and I2S support
• Package Type: 32-WFQFN Exposed Pad
• Operating Temperature Range: -40°C to 85°C
• Voltage Supply Range: 0.95V ~ 1.98V, 1.71V ~ 2V
• Mounting Type: Surface Mount

The WM8918CGEFL/RV meets all these electrical and mechanical parameters, making it a direct functional equivalent. The primary distinction is product status: WM8918CGEFL/RV is active and available in production quantities, whereas WM8912CGEFL/RV is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The WM8918CGEFL/RV is the direct substitute for WM8912CGEFL/RV based on identical electrical specifications and package configuration. Selection of WM8918CGEFL/RV is supported by the following factors:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance certification meets current environmental and regulatory requirements
• Identical functional parameters eliminate circuit redesign requirements
• Tape & Reel packaging option supports automated assembly processes
• Equivalent moisture sensitivity rating maintains handling and storage requirements

No design modifications are required when transitioning from WM8912CGEFL/RV to WM8918CGEFL/RV.

Frequently Asked Questions (FAQ)

Q: Are WM8912CGEFL/RV and WM8918CGEFL/RV pin-compatible?

A: Yes. Both parts use the 32-WFQFN Exposed Pad package with identical pinout, electrical specifications, and operating parameters. Direct substitution is possible without PCB redesign.

Q: What is the primary reason for substitution?

A: WM8912CGEFL/RV is obsolete. WM8918CGEFL/RV is the active equivalent part from the same manufacturer with identical functional specifications.

Q: Are there differences in supply voltage requirements?

A: No. Both parts operate within the same voltage supply range: 0.95V ~ 1.98V and 1.71V ~ 2V. Existing power supply designs require no modification.

Q: Does packaging differ between these parts?

A: The electrical package (32-WFQFN) is identical. WM8918CGEFL/RV is available in Tape & Reel (TR) packaging, which is standard for production environments. Original packaging specification for WM8912CGEFL/RV was not provided.

Q: Are there compliance or certification differences?

A: WM8918CGEFL/RV carries ROHS3 compliance certification. Both parts are REACH Unaffected and classified under ECCN EAR99. Moisture sensitivity level is identical at MSL 3 (168 Hours).

Q: Can WM8918CGEFL/RV be used in existing designs without modification?

A: Yes. Identical electrical and mechanical specifications allow direct substitution without circuit or firmware changes.
