TDA8024AT/C1,118 Equivalent & Substitute Parts

Part Overview

The TDA8024AT/C1,118 is a specialized interface IC manufactured by NXP USA Inc., designed for analog interface applications. This component is packaged in a 28-SOIC form factor and operates within a supply voltage range of 2.7V to 6.5V. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs requiring similar interface capabilities.

Substitute Part Grouping Explanation

The TDA8035HN/C2/S1J is identified as the manufacturer-recommended substitute for the TDA8024AT/C1,118. Substitution eligibility is determined by the following parameters:

• Interface Type: Both parts provide analog interface functionality
• Mounting Type: Both are surface-mount components
• RoHS Compliance: Both meet ROHS3 requirements
• Moisture Sensitivity: Both have MSL rating of 1 (Unlimited)
• Supply Voltage Compatibility: The substitute operates at 2.7V ~ 5.5V, which overlaps with the original part's 2.7V ~ 6.5V range within the 2.7V ~ 5.5V window
• Product Status: The substitute is active and currently in production

The primary difference is the package format: the substitute uses a 32-VFQFN Exposed Pad package instead of the 28-SOIC package, requiring PCB layout and footprint modifications.

Parameter Comparison

Engineering Selection Recommendations

The TDA8035HN/C2/S1J is the manufacturer-recommended substitute and is suitable for applications where the original TDA8024AT/C1,118 is no longer available. Selection of this substitute is supported by:

• Active product status with high inventory availability (95,400 pcs)
• Full ROHS3 compliance matching the original part
• Identical MSL rating and REACH status
• Supply voltage range compatibility within the 2.7V ~ 5.5V operating window
• Identical interface classification (Analog)

Design implementation requires PCB layout modification to accommodate the 32-VFQFN package format in place of the original 28-SOIC package. Pin mapping and functional equivalence must be verified against the respective datasheets prior to production implementation.

Frequently Asked Questions (FAQ)

Q: Can the TDA8035HN/C2/S1J be used as a direct drop-in replacement?

A: No. While functionally equivalent for analog interface applications, the substitute uses a different package format (32-VFQFN vs. 28-SOIC). PCB layout and footprint modifications are required. Pin assignments must be cross-referenced between datasheets.

Q: What is the voltage compatibility between these parts?

A: The original part operates at 2.7V ~ 6.5V, while the substitute operates at 2.7V ~ 5.5V. For applications requiring operation above 5.5V, the substitute is not suitable. For applications within the 2.7V ~ 5.5V range, both parts are compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both the TDA8024AT/C1,118 and TDA8035HN/C2/S1J are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity rating for these components?

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Why is the original part obsolete?

A: The TDA8024AT/C1,118 is classified as obsolete by the manufacturer. The TDA8035HN/C2/S1J represents the active product line continuation for this interface function category.
