Key Parameters

Substitute Part Grouping Explanation

Substitution of the TDA8024T/C1,518 is determined by the following critical parameters:

• Interface Type: Both main and substitute parts must function as analog interface devices
• Supply Voltage Compatibility: The substitute must operate within a voltage range that encompasses or is compatible with the original specification
• Mounting Type: Surface mount compatibility is maintained across the substitution
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be preserved
• Manufacturer Continuity: NXP semiconductor family maintains functional equivalence

The TDA8035HN/C2/S1J qualifies as a manufacturer-recommended substitute based on these parameters, despite the package format change from 28-SOIC to 32-HVQFN. This substitution is supported by NXP's product transition documentation.

Parameter Comparison

Engineering Selection Recommendations

The TDA8035HN/C2/S1J is designated as the manufacturer-recommended substitute for the obsolete TDA8024T/C1,518. Selection of this alternative is supported by:

• Active Product Status: The substitute maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements
• Voltage Range Compatibility: The substitute operates within 2.7V to 5.5V, which is contained within the original part's 2.7V to 6.5V specification, ensuring compatibility in applications operating at or below 5.5V
• Moisture Sensitivity Equivalence: Both parts share MSL 1 (Unlimited) classification, indicating identical moisture handling requirements
• NXP Product Family: Both components belong to the NXP semiconductor interface product line, confirming functional equivalence through manufacturer documentation

Frequently Asked Questions (FAQ)

Q: Why is the TDA8024T/C1,518 being replaced? A: The TDA8024T/C1,518 is classified as obsolete. The TDA8035HN/C2/S1J is the active, manufacturer-recommended alternative that maintains functional equivalence for analog interface applications.

Q: What is the primary difference between these parts? A: The main difference is the package format. The original uses a 28-SOIC package, while the substitute uses a 32-VFQFN Exposed Pad package. Both are surface mount configurations.

Q: Is the voltage supply range compatible? A: The substitute operates at 2.7V to 5.5V, which is within the lower portion of the original part's 2.7V to 6.5V range. Applications requiring operation above 5.5V require design evaluation.

Q: Are there any compliance differences? A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Will I need to modify my PCB layout? A: Yes. The package change from 28-SOIC to 32-VFQFN requires PCB redesign to accommodate the different footprint and pin configuration.

Q: Is this substitution supported by NXP? A: Yes. The TDA8035HN/C2/S1J is listed as the manufacturer-recommended substitute for the TDA8024T/C1,518.
