TSOP39538 Equivalent & Substitute Parts

Part Overview

The TSOP39538 is a remote receiver sensor manufactured by Vishay Semiconductor Opto Division, designed for infrared signal reception at 38.0kHz frequency with a sensing distance of 45 meters. This through-hole optical sensor operates across a supply voltage range of 2.5V to 5.5V with a supply current of 350µA. The component is currently in active product status with ROHS3 compliance and is available in bulk packaging with 1074 pieces in stock.

Identifying equivalent and substitute parts is necessary when the primary component becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits component optimization based on specific application requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSOP39538 is determined by the following critical parameters:

• B.P.F. Center Frequency: Must be 38.0kHz to maintain compatibility with existing infrared remote control protocols
• Sensing Distance: Must be 45m to preserve detection range performance
• Voltage Supply Range: Must accommodate 2.5V ~ 5.5V operation
• Current Supply: Must be 350µA to ensure power budget compatibility
• Mounting Type: Must be Through Hole to maintain PCB assembly compatibility
• Manufacturer: Vishay Semiconductor Opto Division maintains consistent electrical and mechanical specifications across the product line

The TSOP38538 qualifies as a direct substitute based on matching all critical electrical parameters and maintaining the same through-hole mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the TSOP39538 and TSOP38538 are active products from Vishay Semiconductor Opto Division with ROHS3 compliance. Selection between these components should be based on the following factors:

TSOP39538 is suitable when top-view orientation is required for the application's optical reception geometry and when the 72-hour moisture sensitivity window aligns with manufacturing and storage conditions.

TSOP38538 is suitable when side-view orientation is compatible with the PCB layout and when unlimited moisture sensitivity (MSL 1) is preferred for extended storage or humid environment handling. This substitute also provides higher current inventory availability.

Both components maintain identical electrical specifications for frequency response, sensing distance, supply voltage, and current consumption, ensuring functional equivalence in remote receiver applications.

Frequently Asked Questions (FAQ)

Q: Can TSOP38538 replace TSOP39538 in existing designs?

A: Yes. Both components share identical B.P.F. center frequency (38.0kHz), sensing distance (45m), supply voltage range (2.5V ~ 5.5V), and current consumption (350µA). The primary difference is orientation: TSOP39538 uses top-view orientation while TSOP38538 uses side-view orientation. PCB layout compatibility must be verified based on the specific mounting orientation required.

Q: What is the significance of the orientation difference?

A: Orientation refers to the physical direction of the infrared receiver window relative to the component body. Top-view orientation (TSOP39538) positions the receiver window on the top surface, while side-view orientation (TSOP38538) positions it on the side. This affects PCB placement and the angle at which infrared signals are received.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and carry the same ECCN and HTSUS classifications. The primary compliance difference is Moisture Sensitivity Level: TSOP39538 is MSL 4 (72-hour limit), while TSOP38538 is MSL 1 (unlimited). This affects storage and handling requirements but does not impact functional performance.

Q: Which part should be selected for new designs?

A: Selection depends on PCB layout requirements and storage conditions. If side-view orientation is acceptable and extended storage flexibility is beneficial, TSOP38538 offers advantages through MSL 1 rating and higher inventory availability. If top-view orientation is mandatory, TSOP39538 is the appropriate choice.

Q: Are both parts suitable for 38kHz infrared remote control applications?

A: Yes. Both components are designed for 38.0kHz infrared remote receiver applications with 45-meter sensing distance, making them suitable for consumer electronics, home automation, and industrial remote control systems operating within the specified voltage and current parameters.
