Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSMP4138SB1 is determined by electrical and mechanical parameter equivalence across the following critical specifications:

Electrical Parameters:

• B.P.F. Center Frequency: 38.0 kHz (infrared protocol standard)
• Voltage Supply Range: 2.5 V ~ 5.5 V (power compatibility)
• Current Supply: 700 µA (power consumption)
• Operating Temperature Range: -25°C ~ 85°C (thermal envelope)

Mechanical Parameters:

• Mounting Type: Through Hole (PCB assembly compatibility)
• Orientation: Side View (spatial orientation and footprint)
• Sensing Distance: 9m (functional range)

Compliance Parameters:

• REACH Status: REACH Unaffected (regulatory compliance)
• Manufacturer: Vishay Semiconductor Opto Division (supply chain consistency)

Substitute parts must match all electrical and mechanical parameters without deviation to ensure direct functional replacement without circuit redesign or board layout modification.
