Substitute Part Grouping Explanation

Substitution of the TSOP4137 is determined by the following critical parameters:

  • Sensing Distance: 45m (must match)
  • Mounting Type: Through Hole (must match)
  • Orientation: Side View (must match)
  • Operating Temperature Range: -25°C ~ 85°C (must match or exceed)
  • B.P.F. Center Frequency: 36.0kHz nominal (allowable tolerance range: 36.7kHz acceptable for remote receiver applications)
  • Voltage Supply Range: Substitute must operate within or encompass the original 4.5 V ~ 5.5 V range
  • RoHS and Compliance Status: ROHS3 Compliant required

The TSOP2237 qualifies as a manufacturer-recommended substitute based on these parameters. Both components share identical sensing distance, mounting configuration, orientation, and operating temperature specifications. The B.P.F. center frequency variance (36.7kHz versus 36.0kHz) remains within acceptable tolerance for remote receiver sensor applications. The TSOP2237 demonstrates superior voltage supply flexibility (2.7 V ~ 5.5 V) and reduced current consumption (850 µA versus 1.1 mA), while maintaining full compliance with RoHS3 and environmental standards.

  • Enhanced Performance Characteristics: The TSOP2237 provides expanded voltage supply range (2.7 V ~ 5.5 V) and reduced current consumption (850 µA), offering design flexibility and improved power efficiency compared to the original TSOP4137.

Frequently Asked Questions (FAQ)

Q: Can the TSOP2237 directly replace the TSOP4137 in existing designs?

A: Yes. Both components share identical sensing distance (45m), through-hole mounting configuration, side-view orientation, and operating temperature range (-25°C ~ 85°C). The TSOP2237 is the manufacturer-recommended substitute.

Q: What is the significance of the B.P.F. center frequency difference (36.0kHz versus 36.7kHz)?

A: The B.P.F. center frequency variance of 0.7kHz falls within acceptable tolerance for remote receiver sensor applications. Both components are designed for infrared signal reception in the 36kHz band and maintain functional compatibility.

Q: Does the TSOP2237 require circuit modifications?

A: No circuit modifications are required. The TSOP2237 maintains identical pinout, mounting type, and operating temperature specifications. The expanded voltage supply range (2.7 V ~ 5.5 V) of the TSOP2237 is backward compatible with designs originally specified for 4.5 V ~ 5.5 V operation.

Q: What are the advantages of the TSOP2237 over the TSOP4137?

A: The TSOP2237 offers active product status, expanded voltage supply flexibility (2.7 V ~ 5.5 V), and reduced current consumption (850 µA versus 1.1 mA). These characteristics provide improved supply chain availability and enhanced power efficiency.

Q: Are both components RoHS compliant?

A: Yes. Both the TSOP4137 and TSOP2237 are ROHS3 compliant and REACH unaffected, satisfying environmental and regulatory requirements.

Q: What packaging is available for the TSOP2237?

A: The TSOP2237 is supplied in tube packaging, suitable for automated assembly and component handling processes.
