Substitute Part Grouping Explanation

Substitute parts for the TSOP59238 are qualified based on the following critical parameters that determine functional equivalence:

• B.P.F. Center Frequency: 38.0kHz (identical across all parts)
• Sensing Distance: 40m (identical across all parts)
• Voltage Supply Range: 2.5 V ~ 5.5 V (identical across all parts)
• Current Supply: 700 µA (identical across all parts)
• Mounting Type: Through Hole (identical across all parts)
• Operating Temperature Range: -25°C ~ 85°C (identical across all parts)
• RoHS Compliance: ROHS3 Compliant (identical across all parts)

The substitute parts TSOP58238 and TSOP58438 maintain all critical electrical and thermal specifications. The primary difference is component orientation: TSOP59238 features top view orientation, while TSOP58238 and TSOP58438 feature side view orientation. This orientation difference affects PCB layout and mechanical integration but does not impact electrical performance or functional capability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TSOP59238, TSOP58238, and TSOP58438—are active products from Vishay Semiconductor Opto Division with identical electrical specifications and ROHS3 compliance. Selection between these parts should be based on:

Orientation Requirements: The TSOP59238 with top view orientation is suitable for applications requiring upward-facing sensor detection. The TSOP58238 and TSOP58438 with side view orientation are suitable for applications requiring lateral-facing sensor detection. PCB layout and mechanical housing design determine which orientation is appropriate.

Moisture Sensitivity: The TSOP59238 has MSL 4 (72 hours), while TSOP58238 and TSOP58438 have MSL 1 (unlimited). For applications with extended storage periods or high-humidity environments, TSOP58238 or TSOP58438 provide superior moisture resistance.

Supply Availability: All parts are in active production. TSOP58438 has the highest inventory availability (9278 pcs), followed by TSOP58238 (3300 pcs) and TSOP59238 (875 pcs).

Frequently Asked Questions (FAQ)

Q: Can TSOP58238 or TSOP58438 directly replace TSOP59238 in an existing design?

A: Direct replacement depends on PCB layout and mechanical housing. The electrical specifications are identical, but the orientation difference (top view vs. side view) requires verification that the sensor's detection angle aligns with the application's infrared source position. Physical testing in the target application is necessary to confirm proper signal reception.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: MSL 4 (TSOP59238) allows 72 hours of exposure to 85°C and 85% relative humidity before soldering. MSL 1 (TSOP58238, TSOP58438) has unlimited shelf life under standard conditions. For high-volume manufacturing with extended lead times or storage in humid environments, MSL 1 parts reduce the risk of moisture-induced soldering defects.

Q: Are all three parts ROHS3 compliant?

A: Yes. TSOP59238, TSOP58238, and TSOP58438 are all ROHS3 compliant and suitable for applications requiring restricted substance compliance.

Q: What determines whether a part is a valid substitute?

A: Valid substitutes must maintain identical electrical specifications (frequency, voltage range, current draw, sensing distance, operating temperature) and mounting type. Orientation differences are acceptable if the application's mechanical design accommodates the alternative sensor direction.

Q: Which part should be selected for new designs?

A: For new designs, TSOP58238 or TSOP58438 are preferred due to superior moisture sensitivity ratings (MSL 1) and higher inventory availability. The choice between these two depends on PCB layout requirements and the specific orientation needed for the application.
