Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSOP2238 are qualified based on the following critical parameters that determine functional compatibility:

• B.P.F. Center Frequency: 38.0kHz (must match exactly for protocol compatibility)
• Sensing Distance: 45m (operational range requirement)
• Voltage Supply Range: 2.5 V ~ 5.5 V (circuit integration requirement)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Orientation: Side View (mechanical fit requirement)
• Operating Temperature Range: -25°C ~ 85°C (environmental specification)
• Packaging: Tube (handling and storage specification)

The TSOP34838 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in supply current do not affect substitution eligibility when all other parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the TSOP2238 and TSOP34838 are active production parts from Vishay Semiconductor Opto Division with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts should be based on supply availability and current consumption requirements for the specific application. The TSOP34838 offers lower supply current (450 µA versus 700 µA), which may provide advantages in power-constrained designs while maintaining all functional and environmental specifications. Both parts are suitable for direct substitution in 38.0kHz infrared remote receiver applications requiring 45-meter sensing distance.

Frequently Asked Questions (FAQ)

Q: Can TSOP34838 replace TSOP2238 in existing designs? A: Yes. The TSOP34838 is a direct substitute for TSOP2238. All critical parameters including center frequency (38.0kHz), sensing distance (45m), supply voltage range (2.5-5.5V), mounting type (through hole), and operating temperature range (-25°C to 85°C) are identical. The lower supply current of TSOP34838 does not affect functional compatibility.

Q: What is the difference in supply current between these parts? A: The TSOP2238 draws 700 µA while the TSOP34838 draws 450 µA. This 250 µA difference may be relevant for battery-powered or power-sensitive applications but does not affect the sensor's detection capability or protocol compatibility.

Q: Are both parts available in the same packaging? A: Yes. Both TSOP2238 and TSOP34838 are supplied in tube packaging with identical through-hole mounting orientation (side view), ensuring mechanical compatibility in PCB assembly.

Q: Do these parts have the same compliance certifications? A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting the same regulatory requirements for electronic component applications.

Q: What determines if a part can substitute for TSOP2238? A: Substitute parts must match the following parameters: 38.0kHz center frequency, 45-meter sensing distance, 2.5-5.5V supply voltage range, through-hole mounting, side-view orientation, and -25°C to 85°C operating temperature range. Compliance status and packaging format must also align.
