Substitute Part Grouping Explanation

Substitution eligibility for the TSMP77138TT is determined by strict equivalence across the following critical parameters:

• B.P.F. Center Frequency: 38.0 kHz (standard IR remote control frequency)
• Sensing Distance: 7 m (detection range capability)
• Voltage Supply Range: 2.5 V ~ 5.5 V (power compatibility)
• Current Supply: 700 µA (power consumption profile)
• Mounting Type: Surface Mount (PCB integration method)
• Orientation: Top View (component placement orientation)
• Operating Temperature Range: -25°C ~ 85°C (thermal operating envelope)

Substitute parts must maintain identical specifications across all parameters listed above to ensure functional and electrical compatibility without circuit redesign or board layout modification.
