TCLT1014 Equivalent & Substitute Parts

Part Overview

The TCLT1014 is an optoisolator with transistor output manufactured by Vishay Semiconductor Opto Division. This component provides 5000Vrms isolation in a 4-SMD surface mount package, designed for applications requiring galvanic isolation between input and output circuits. The part is currently active in production with 2051 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility.

Substitute Part Grouping Explanation

Substitute parts for the TCLT1014 are identified based on strict equivalence of the following critical parameters:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Transistor
• Current Transfer Ratio range: 160% to 320% @ 10mA
• Voltage - Output (Max): 70V
• Current - Output / Channel: 50mA
• Package / Case: 4-SMD, Gull Wing
• Mounting Type: Surface Mount
• Operating Temperature range: -55°C ~ 110°C

The VO610A-4X017T meets all these criteria and is classified as a parametric equivalent. Both parts are manufactured by Vishay Semiconductor Opto Division, share identical electrical specifications, and are housed in compatible 4-SMD surface mount packages.

Parameter Comparison

Engineering Selection Recommendations

Both the TCLT1014 and VO610A-4X017T are active products from Vishay Semiconductor Opto Division with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability and inventory levels (TCLT1014: 2051 units; VO610A-4X017T: 1863 units)
• Supply chain lead times
• Design documentation and reference schematics already in use
• PCB layout and assembly process compatibility with the 4-SMD, Gull Wing package

Both parts are suitable for direct substitution in applications requiring 5000Vrms isolation with single-channel transistor output in the specified voltage and current ranges.
