Key Parameters

Substitute Part Grouping Explanation

Substitution of the STA30613TR is determined by compatibility across the following critical parameters:

Package and Mounting Compatibility: Both the main part and substitute must use the 64-LQFP surface mount package to ensure PCB layout and assembly process compatibility.

Interface Compatibility: Both parts must support I2C and I2S interfaces to maintain signal communication with host controllers and audio data streams.

Supply Voltage Compatibility: Both parts must operate within overlapping or identical supply voltage ranges (3V ~ 3.6V) to ensure proper circuit operation without additional power supply modifications.

Functional Classification: Both parts must be classified as fully integrated audio processors to ensure equivalent functional capability.

Series Designation: Both parts belong to the STMicroelectronics DDX™ series, indicating compatibility within the same product family.

The STA309A13TR meets all substitution criteria. While it provides enhanced specifications (8 channels versus 6 channels, extended operating temperature range, and active product status), it maintains full compatibility with the core electrical and mechanical parameters of the STA30613TR.

Parameter Comparison

Engineering Selection Recommendations

The STA309A13TR is a direct substitute for the STA30613TR based on electrical and mechanical compatibility. Both devices share identical supply voltage specifications (3V ~ 3.6V), interface protocols (I2C, I2S), package geometry (64-LQFP), and mounting methodology (surface mount).

The STA309A13TR offers enhanced specifications compared to the STA30613TR. The substitute provides 8 processing channels instead of 6, extending the functional capacity of audio processing applications. The operating temperature range of the STA309A13TR extends to -40°C, providing broader environmental operating capability compared to the -20°C minimum of the STA30613TR.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing and distribution requirements. The STA309A13TR carries active product status, ensuring ongoing availability and manufacturing support from STMicroelectronics, whereas the STA30613TR is obsolete.

The moisture sensitivity level differs between the two parts. The STA30613TR specifies MSL 1 (unlimited), while the STA309A13TR specifies MSL 3 (168 hours). This difference requires adherence to appropriate moisture handling and storage protocols during component management and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the STA309A13TR directly replace the STA30613TR in existing designs?

A: Yes. Both parts share identical package geometry (64-LQFP), supply voltage range (3V ~ 3.6V), and interface specifications (I2C, I2S). PCB layout and electrical connections remain compatible. The increased channel count (8 versus 6) and extended temperature range represent functional enhancements that do not compromise backward compatibility.

Q: What is the significance of the different channel counts?

A: The STA30613TR provides 6 processing channels, while the STA309A13TR provides 8 channels. For applications utilizing only 6 channels, the additional 2 channels in the substitute remain unused but do not affect operation. Applications requiring more than 6 channels benefit from the expanded capacity of the STA309A13TR.

Q: How do the operating temperature ranges differ?

A: The STA30613TR operates from -20°C to 125°C, while the STA309A13TR operates from -40°C to 125°C. The STA309A13TR supports extended low-temperature operation, suitable for applications requiring broader environmental performance. For applications within the -20°C to 125°C range, both parts perform equivalently.

Q: What are the moisture sensitivity implications?

A: The STA30613TR specifies MSL 1 (unlimited moisture sensitivity level), while the STA309A13TR specifies MSL 3 (168 hours). MSL 3 requires component storage in controlled humidity environments and limits the time between package opening and assembly to 168 hours. Proper moisture handling procedures must be implemented for the STA309A13TR during component management and production workflows.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the STA30613TR and STA309A13TR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: What is the availability status of each part?

A: The STA30613TR is classified as obsolete, indicating discontinued manufacturing. The STA309A13TR is classified as active, indicating ongoing production and availability from STMicroelectronics. For new designs and long-term supply assurance, the STA309A13TR is the recommended selection.

Q: Are the packaging options identical?

A: Both parts are available in 64-TQFP (10x10) surface mount packages. The STA30613TR is supplied in Cut Tape (CT) packaging, while the STA309A13TR is available in both Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility in component procurement and handling.
