TDF8599ATH/N2/S6 Class D Audio Amplifier IC Equivalent & Substitute Parts

Part Overview

The TDF8599ATH/N2/S6 is a Class D audio amplifier integrated circuit manufactured by NXP USA Inc., designed for mono or stereo audio applications. This device delivers 250W output power at 2Ω load (single channel) or 135W at 4Ω load (dual channel) across a supply voltage range of 8V to 35V. The IC integrates differential inputs, I2C control interface, mute functionality, and comprehensive protection features including short-circuit and thermal protection.

The TDF8599ATH/N2/S6 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing production requirements, field repairs, and system maintenance where this amplifier IC is specified in existing designs.

Substitute Part Grouping Explanation

Substitution eligibility for the TDF8599ATH/N2/S6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Amplifier Type: Class D
• Output Configuration: 1-Channel (Mono) or 2-Channel (Stereo)
• Max Output Power: 250W @ 2Ω (single channel); 135W @ 4Ω (dual channel)
• Supply Voltage Range: 8V to 35V
• Integrated Feature Set: Depop, Differential Inputs, I2C, Mute, Short-Circuit and Thermal Protection
• Package Type: 36-BSSOP with Exposed Pad
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS3 Compliance
• Manufacturer: NXP USA Inc.

The substitute part TDF8599ATH/N2/S6CY meets all mandatory matching parameters and compliance requirements. The primary distinction between the main part and substitute is product status (obsolete versus active) and packaging format (bulk versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

The TDF8599ATH/N2/S6CY is the direct substitute for the obsolete TDF8599ATH/N2/S6. Both parts are manufactured by NXP USA Inc. and share identical electrical specifications, output power ratings, supply voltage range, and integrated protection features. Both devices comply with ROHS3 standards.

Selection Basis:

The substitute part is recommended based on:

1. Product Status: The TDF8599ATH/N2/S6CY maintains active production status, ensuring long-term availability and supply chain continuity.
2. Electrical Equivalence: All functional parameters, output power specifications, and feature sets are identical.
3. Package Compatibility: Both parts use the 36-BSSOP package with exposed pad, ensuring PCB layout and thermal management compatibility.
4. Compliance Alignment: Both parts meet ROHS3 requirements for environmental compliance.

Packaging Consideration: The substitute is supplied in Tape & Reel format, which is standard for production environments. The main part was supplied in bulk format. Tape & Reel packaging is suitable for automated assembly processes and provides equivalent component quality and reliability.

Moisture Sensitivity: The substitute part has MSL 3 (168 hours), compared to MSL 1 (unlimited) for the main part. This requires standard moisture control procedures during storage and handling, consistent with industry practice for surface-mount components.

Frequently Asked Questions (FAQ)

Q: Can the TDF8599ATH/N2/S6CY be used as a direct replacement for the TDF8599ATH/N2/S6 in existing designs?

A: Yes. The TDF8599ATH/N2/S6CY is electrically and mechanically equivalent. Both parts deliver identical output power (250W @ 2Ω single channel; 135W @ 4Ω dual channel), operate across the same supply voltage range (8V to 35V), and integrate the same feature set (Depop, Differential Inputs, I2C, Mute, Short-Circuit and Thermal Protection). The 36-BSSOP package dimensions and pinout are identical, allowing direct PCB substitution.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. The TDF8599ATH/N2/S6 is obsolete and was supplied in bulk packaging. The TDF8599ATH/N2/S6CY is in active production and is supplied in Tape & Reel format. The suffix "CY" indicates the Tape & Reel packaging variant. Electrical performance and functional specifications are identical.

Q: Does the Tape & Reel packaging affect component performance or reliability?

A: No. Tape & Reel is a standard packaging format for surface-mount components and does not affect electrical performance, reliability, or thermal characteristics. The component itself is identical; only the delivery format differs.

Q: What are the moisture handling requirements for the TDF8599ATH/N2/S6CY?

A: The substitute part has MSL 3 rating, requiring moisture control for 168 hours after package opening. This is standard practice for surface-mount ICs and requires storage in dry conditions (typically below 30% relative humidity) or in moisture-barrier packaging. Standard industry handling procedures apply.

Q: Are both parts RoHS compliant?

A: Yes. Both the TDF8599ATH/N2/S6 and TDF8599ATH/N2/S6CY are ROHS3 compliant, meeting environmental and hazardous substance restrictions.

Q: Can I use the TDF8599ATH/N2/S6CY in new designs?

A: Yes. The TDF8599ATH/N2/S6CY is in active production status and is suitable for new design implementations. It provides the same Class D amplifier functionality, output power, and integrated protection features as the obsolete part.
