Parameter Comparison

Engineering Selection Recommendations

The TDA8035HN/C1,118 is the designated substitute for the TDA8034T/C1,112 based on the following engineering criteria:

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring no regulatory barriers to substitution in existing applications.

Supply Chain Status: The TDA8034T/C1,112 is in Last Time Buy status with limited availability (1467 pcs). The TDA8035HN/C1,118 is Active with significantly higher inventory (13970 pcs), providing long-term supply security.

Voltage Compatibility: The substitute's expanded voltage range (2.7V ~ 5.5V) encompasses the original part's operating points (3V, 5V), ensuring functional compatibility in existing designs without circuit modification.

Manufacturer Continuity: Both parts originate from NXP USA Inc., maintaining design consistency and technical support continuity.

Package Consideration: The substitute uses a 32-VFQFN package versus the original 16-SOIC package. PCB layout redesign is required for this substitution due to different pin counts and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can the TDA8035HN/C1,118 directly replace the TDA8034T/C1,112 without PCB modification?

A: No. The substitute uses a 32-VFQFN package with different pin configuration compared to the original 16-SOIC package. PCB layout redesign is mandatory.

Q: Are there voltage compatibility concerns when substituting?

A: No. The substitute's supply voltage range (2.7V ~ 5.5V) fully encompasses the original part's operating voltages (3V, 5V). Existing power supply designs remain compatible.

Q: What is the significance of the Last Time Buy status on the TDA8034T/C1,112?

A: Last Time Buy indicates the manufacturer will no longer produce this part after current inventory is depleted. Substitution planning is necessary for long-term product support.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and share identical ECCN (EAR99) and HTSUS classifications.

Q: What is the difference in packaging format between these parts?

A: The TDA8034T/C1,112 is supplied in Tube packaging, while the TDA8035HN/C1,118 is supplied in Tape & Reel (TR) format. This affects handling and automated assembly processes.

Q: Are there any moisture sensitivity differences?

A: No. Both parts have identical MSL 1 (Unlimited) ratings, requiring the same moisture control and storage protocols.
