TSOP39240 Equivalent & Substitute Parts

Part Overview

The TSOP39240 is an active remote receiver sensor manufactured by Vishay Semiconductor Opto Division, designed for infrared remote control applications. This through-hole optical sensor operates at a center frequency of 40.0kHz with a sensing distance of 45 meters. The component is currently in active product status with 740 units in stock. Finding equivalent and substitute parts may be necessary due to inventory constraints, lead time considerations, or specific application requirements where alternative orientations or moisture sensitivity levels are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSOP39240 is determined by the following critical parameters that must remain constant across equivalent parts:

• B.P.F. Center Frequency: 40.0kHz (infrared carrier frequency compatibility)
• Sensing Distance: 45m (detection range requirement)
• Voltage Supply Range: 2.5 V ~ 5.5 V (power supply compatibility)
• Current Supply: 450 µA (power consumption specification)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Operating Temperature Range: -25°C ~ 85°C (thermal operating envelope)

The TSOP38240 qualifies as a direct substitute based on these parameters. Differences in orientation (Top View vs. Side View) and moisture sensitivity level (MSL 4 vs. MSL 1) do not affect functional equivalence for standard applications, as both components maintain identical electrical and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSOP39240 and TSOP38240 are active products from Vishay Semiconductor Opto Division with full ROHS3 compliance. Selection between these parts should be based on:

TSOP39240 is the primary choice when top-view orientation is required for the PCB layout and when moisture sensitivity level MSL 4 (72-hour shelf life requirement) is acceptable for the manufacturing process.

TSOP38240 is the appropriate substitute when side-view orientation is compatible with the application design and when extended moisture tolerance (MSL 1, unlimited shelf life) is beneficial for inventory management and supply chain flexibility.

Both components are functionally equivalent for 40.0kHz infrared remote receiver applications with 45-meter sensing distance and identical electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can TSOP38240 be used as a direct replacement for TSOP39240 in existing designs?

A: Yes, the TSOP38240 is functionally equivalent. The primary consideration is PCB layout compatibility. The TSOP39240 features top-view orientation while the TSOP38240 features side-view orientation. Verify that the receiving lens orientation aligns with your infrared signal source positioning before substitution.

Q: What is the significance of the different MSL ratings between these parts?

A: MSL (Moisture Sensitivity Level) indicates shelf life under controlled humidity conditions. TSOP39240 has MSL 4 (72-hour limit), while TSOP38240 has MSL 1 (unlimited). For high-volume manufacturing with extended component storage, TSOP38240 offers greater flexibility. Both parts perform identically once soldered and operating.

Q: Are the electrical specifications identical between TSOP39240 and TSOP38240?

A: Yes. Both parts operate at 40.0kHz center frequency, support 2.5V to 5.5V supply voltage, draw 450µA current, achieve 45-meter sensing distance, and operate across -25°C to 85°C temperature range.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on mechanical layout requirements. Consider TSOP38240 if extended shelf life and reduced moisture handling procedures are advantageous for your supply chain.
