• Compatible voltage load range: 0 V ~ 40 V
• Equal or greater load current capability: 250 mA minimum
• Compatible input voltage: 1.2VDC to 1.14VDC range
• Output type: AC, DC or AC, DC (RF) capable

Mechanical Compatibility Criteria:

• Identical package designation: 4-SOP (0.173", 4.40mm)
• Identical termination style: Gull Wing
• Surface mount mounting type

The AQY221R2S manufactured by Panasonic Electric Works meets all substitution criteria and maintains active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The AQY221R2S represents a direct functional equivalent to the PS7200E-1A-A. Key advantages include active product status ensuring supply chain continuity, ROHS3 compliance for regulatory adherence, and superior on-state resistance characteristics (1.25 Ohms versus 1.6 Ohms). The REACH Unaffected status provides additional regulatory advantage over the REACH Affected status of the original part. Both devices share identical electrical operating parameters, package geometry, and termination specifications required for PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AQY221R2S directly replace the PS7200E-1A-A on existing PCBs? A: Yes. The AQY221R2S is pin-compatible and mechanically identical. Both employ 4-SOP Gull Wing termination with identical footprint dimensions (0.173", 4.40mm). No PCB design modifications are required.

Q: What is the impact of the lower input voltage requirement of AQY221R2S (1.14VDC versus 1.2VDC)? A: The lower trigger voltage of the AQY221R2S enhances circuit performance by allowing reliable operation across a broader input voltage range. This represents a performance improvement over the original specification.

Q: Are there differences in load handling capability? A: Both parts specify identical load current capability at 250 mA with matching voltage load range of 0 V ~ 40 V. The AQY221R2S features superior on-state resistance (1.25 Ohms maximum), resulting in lower power dissipation during operation.

Q: What is the significance of AC, DC (RF) output type specification? A: The AQY221R2S output type includes RF capability, indicating suitability for radio frequency applications. This represents an enhancement over the AC, DC specification of the original part, with no operational limitations for standard AC/DC applications.

Q: Are there compliance or regulatory considerations for substitution? A: The AQY221R2S provides superior regulatory positioning with ROHS3 compliance and REACH Unaffected status, compared to the REACH Affected status of the PS7200E-1A-A. For applications subject to environmental or regulatory requirements, the substitute part offers enhanced compliance certainty.

Q: Does packaging differ between these parts? A: Both parts are supplied in industry-standard surface mount packages. The AQY221R2S is supplied in Tube packaging, while the original PS7200E-1A-A packaging format is not specified. Both maintain identical component footprints suitable for automated assembly.
