Engineering Selection Recommendations

Primary Substitute: TAS5112ADFDR

The TAS5112ADFDR is the recommended substitute for the TAS5112DFDRG4. This part maintains identical electrical specifications and mechanical compatibility while offering the advantage of Active product status. The TAS5112ADFDR is supplied in Tape & Reel packaging and demonstrates higher current inventory availability (2203 pcs), ensuring supply chain continuity for new designs and production requirements.

Secondary Substitute: TAS5112DFDR

The TAS5112DFDR provides electrical and mechanical equivalence to the TAS5112DFDRG4. However, this part carries Obsolete product status, indicating limited long-term availability. The TAS5112DFDR should be considered only when TAS5112ADFDR supply is unavailable and immediate component procurement is required. Despite obsolete classification, current inventory levels (7257 pcs) support near-term applications.

Compliance Considerations

All three parts maintain ROHS3 compliance, REACH Unaffected status, and identical MSL ratings. Component selection may be based on product status and supply availability without compromising regulatory or environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can TAS5112ADFDR directly replace TAS5112DFDRG4 in existing designs?

A: Yes. The TAS5112ADFDR maintains identical electrical performance (62W x 2 @ 6Ω, Class D stereo amplification, 16V-25.5V supply), mechanical compatibility (56-PowerTSSOP package), and feature set (Depop, Digital Inputs, Mute, Short-Circuit and Thermal Protection, Shutdown). Pin-for-pin and functional compatibility is confirmed across all provided specifications.

Q: What is the difference between TAS5112ADFDR and TAS5112DFDR?

A: Both parts are electrically and mechanically identical. The primary difference is product status: TAS5112ADFDR is Active, while TAS5112DFDR is Obsolete. For new designs and ongoing production, TAS5112ADFDR is the preferred selection due to long-term availability assurance.

Q: Are there packaging differences between these substitutes?

A: The TAS5112ADFDR is supplied in Tape & Reel packaging, while TAS5112DFDRG4 and TAS5112DFDR do not specify packaging format in the provided data. All three parts use the identical 56-PowerTSSOP (0.240", 6.10mm Width) package type, ensuring mechanical compatibility in PCB assembly.

Q: Do these substitutes meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and carry MSL 3 rating (168 Hours). Regulatory and environmental compliance is maintained across all substitute selections.

Q: What is the operating temperature range for these amplifiers?

A: All three parts operate across 0°C to 70°C (TA). Design thermal management must account for this specified range.
