Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSOP39338 is determined by strict equivalence across the following critical parameters:

• B.P.F. Center Frequency: 38.0kHz (mandatory match for infrared protocol compatibility)
• Sensing Distance: 45m (functional range requirement)
• Voltage Supply Range: 2.5 V ~ 5.5 V (circuit integration compatibility)
• Current Supply: 450 µA (power budget alignment)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Operating Temperature Range: -25°C ~ 85°C (environmental specification)

The TSOP38338 qualifies as a manufacturer-recommended substitute based on matching all critical electrical and functional parameters. Variations in orientation (Top View vs. Side View) and moisture sensitivity level do not affect functional substitution in standard remote receiver applications, as these characteristics relate to component handling and assembly processes rather than electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The TSOP38338 is designated as the manufacturer-recommended substitute for the TSOP39338 based on complete electrical and functional parameter equivalence. Both components maintain active production status and satisfy identical compliance requirements under ROHS3 and REACH regulations.

Selection between TSOP39338 and TSOP38338 should be based on:

• Circuit board layout constraints and component orientation requirements (Top View vs. Side View)
• Moisture exposure conditions during storage and assembly (MSL 4 vs. MSL 1)
• Inventory availability and supply chain lead times
• Cost optimization within procurement cycles

Both parts are suitable for direct substitution in 38.0kHz infrared remote receiver applications without circuit modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can TSOP38338 replace TSOP39338 in existing designs?

A: Yes. The TSOP38338 is electrically and functionally equivalent to the TSOP39338 across all critical parameters including center frequency, sensing distance, supply voltage, current consumption, and operating temperature range. Direct substitution is supported without circuit redesign.

Q: What is the difference between Top View and Side View orientation?

A: Orientation refers to the physical lead configuration and component mounting perspective on the PCB. Top View and Side View variants have identical electrical characteristics but differ in physical package orientation. Selection depends on PCB layout requirements and available mounting space.

Q: Does the difference in Moisture Sensitivity Level affect substitution?

A: Moisture Sensitivity Level (MSL) relates to component handling and storage conditions prior to assembly, not to electrical performance or functional compatibility. TSOP38338 (MSL 1) offers more flexible storage conditions compared to TSOP39338 (MSL 4), which may provide supply chain advantages but does not affect in-circuit operation.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both TSOP39338 and TSOP38338 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What inventory levels are available for each part?

A: TSOP39338 has 1535 units in stock, while TSOP38338 has 3834 units in stock. Higher inventory availability of TSOP38338 may support extended production runs or reduce procurement lead times.
