Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TPS2224APWPR

The TPS2224APWPR is the direct functional equivalent of the TPS2204APWPR, maintaining identical electrical specifications including 4 outputs, 3:4 input-to-output ratio, 1A maximum output current, and 95mOhm on-resistance. The TPS2224APWPR is classified as Active, ensuring ongoing manufacturer support and availability. Both parts are ROHS3 compliant with identical MSL ratings. The TPS2224APWPR is available in Tape & Reel packaging, suitable for high-volume production environments.

Secondary Recommendation: TPS2224PWPR

The TPS2224PWPR provides identical electrical and functional characteristics to the TPS2204APWPR with matching 4-output configuration and 3:4 ratio. This part is classified as Discontinued at DiGi Electronics but maintains full parametric equivalence. Selection of this part should be based on inventory availability and supply chain considerations.

Alternative Consideration: TPS2210APWPR

The TPS2210APWPR differs in output count (2 outputs) and input-to-output ratio (3:2), making it suitable only for applications requiring reduced output channels. All other electrical parameters, fault protection features, operating temperature range, and compliance certifications remain equivalent. This part is classified as Discontinued at DiGi Electronics.

Frequently Asked Questions (FAQ)

Q: Can TPS2224APWPR directly replace TPS2204APWPR in existing designs?

A: Yes. The TPS2224APWPR maintains identical electrical specifications, output configuration, interface protocol, fault protection features, and package dimensions. No circuit modifications are required for direct substitution.

Q: What is the difference between TPS2224APWPR and TPS2224PWPR?

A: Both parts are electrically and functionally identical with matching 4-output configuration, 3:4 ratio, and all electrical parameters. The difference lies in product status: TPS2224APWPR is Active, while TPS2224PWPR is Discontinued at DiGi Electronics. Selection should be based on availability and supply chain requirements.

Q: Why is TPS2210APWPR listed as a substitute if it has different output specifications?

A: TPS2210APWPR is listed as a parametric equivalent based on matching electrical characteristics (current, voltage, on-resistance, protection features, and temperature range). However, the reduced output count (2 vs. 4) and different ratio (3:2 vs. 3:4) make it suitable only for applications with lower output channel requirements. Circuit redesign may be necessary.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the 24-PowerTSSOP package with identical dimensions (0.173", 4.40mm Width), ensuring mechanical compatibility with existing PCB layouts.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant with Moisture Sensitivity Level 2 (1 Year), REACH Unaffected status, and ECCN EAR99 classification. These certifications are consistent across the TPS2204APWPR and all substitute options.
