Substitute Part Grouping Explanation

The TSOP58456 qualifies as a direct substitute for the TSOP59256 based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• B.P.F. Center Frequency: 56.0kHz (identical)
• Sensing Distance: 40m (identical)
• Voltage Supply Range: 2.5 V ~ 5.5 V (identical)
• Current Supply: 700 µA (identical)
• Mounting Type: Through Hole (identical)
• Operating Temperature Range: -25°C ~ 85°C (identical)
• RoHS Compliance: ROHS3 Compliant (identical)
• Manufacturer: Vishay Semiconductor Opto Division (identical)

Differing Parameters:

• Orientation: TSOP59256 features Top View orientation; TSOP58456 features Side View orientation
• Moisture Sensitivity Level (MSL): TSOP59256 is MSL 4 (72 Hours); TSOP58456 is MSL 1 (Unlimited)

The substitution is valid for applications where the component orientation and moisture sensitivity specifications are compatible with the target design requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TSOP59256 and TSOP58456 are active production components from Vishay Semiconductor Opto Division with full ROHS3 compliance. Selection between these parts depends on specific design constraints:

The TSOP59256 with Top View orientation is appropriate for applications where the sensor window must face upward relative to the PCB surface. The TSOP58456 with Side View orientation is suitable for designs requiring lateral sensor window positioning. The TSOP58456 offers superior moisture handling characteristics with MSL 1 (Unlimited) rating compared to the TSOP59256's MSL 4 (72 Hours) specification, making it preferable for applications with extended storage or high-humidity manufacturing environments.

Both components maintain identical electrical performance characteristics, including frequency response, sensing distance, supply voltage range, and current consumption, ensuring functional equivalence in circuit operation.

Frequently Asked Questions (FAQ)

Q: Can TSOP58456 replace TSOP59256 in existing designs?

A: Functional replacement is possible if the PCB layout accommodates the Side View orientation of the TSOP58456 instead of the Top View orientation of the TSOP59256. Electrical performance is identical. Physical mounting geometry must be verified against the specific application's mechanical constraints.

Q: What is the significance of the MSL rating difference?

A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture absorption during storage and handling. TSOP58456 with MSL 1 (Unlimited) can be stored indefinitely without moisture control measures. TSOP59256 with MSL 4 (72 Hours) requires controlled storage conditions and must be used within 72 hours of package opening in standard humidity environments.

Q: Are both parts suitable for 56.0kHz infrared remote control applications?

A: Yes. Both TSOP59256 and TSOP58456 operate at identical 56.0kHz center frequency with 40-meter sensing distance, making them functionally equivalent for infrared remote receiver applications.

Q: What are the supply voltage requirements?

A: Both components operate within the 2.5 V to 5.5 V supply range with 700 µA current consumption, compatible with standard 3.3V and 5V logic systems.

Q: Are both components RoHS compliant?

A: Yes. Both TSOP59256 and TSOP58456 are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.
