TCND3000 Equivalent & Substitute Parts

Part Overview

The TCND3000 is a reflective optical sensor manufactured by Vishay Semiconductor Opto Division, designed for applications requiring adjustable sensing distances between 0.394" and 0.787" (10mm to 20mm). This component operates as a PIN photodiode with a maximum forward current of 50 mA and is housed in a 4-SMD, No Lead surface mount package. The TCND3000 is classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TCND3000 are identified based on the following critical parameters that determine functional compatibility:

• Sensing method: Reflective operation
• Output type: PIN photodiode configuration
• Mounting type: Surface mount technology
• Operating temperature range: -40°C to 85°C minimum
• RoHS compliance: ROHS3 Compliant
• Manufacturer: Vishay Semiconductor Opto Division

The TCND5000 qualifies as a direct substitute based on these core parameters. While the TCND5000 offers an extended sensing distance range (0.079" ~ 0.984" or 2mm ~ 25mm) and increased maximum forward current (100 mA), these represent functional enhancements rather than incompatibilities. Both components maintain identical operating temperature ranges, RoHS compliance status, and reflective sensing methodology.

Parameter Comparison

Engineering Selection Recommendations

The TCND5000 is the designated substitute for the obsolete TCND3000. Selection of the TCND5000 is supported by the following factors:

• Both components maintain ROHS3 compliance, satisfying regulatory requirements for new designs and replacements
• The TCND5000 is classified as active product status, ensuring continued availability and supply chain stability
• Identical operating temperature range (-40°C to 85°C) confirms thermal compatibility with existing circuit designs
• Both components employ PIN photodiode output architecture and reflective sensing methodology, maintaining functional equivalence
• The TCND5000 package format (Module) differs from the TCND3000 (4-SMD, No Lead), requiring mechanical and layout verification during integration

Frequently Asked Questions (FAQ)

Q: Can the TCND5000 directly replace the TCND3000 in existing circuit designs?

A: The TCND5000 provides functional equivalence in sensing method, output type, and operating temperature range. However, the package format differs (Module versus 4-SMD, No Lead), requiring verification of mechanical fit and PCB layout compatibility before implementation.

Q: What are the key differences between the TCND3000 and TCND5000?

A: The TCND5000 extends the sensing distance range from 10-20mm to 2-25mm and increases maximum forward current from 50 mA to 100 mA. The TCND5000 is active product status, whereas the TCND3000 is obsolete. Package format also differs between the two components.

Q: Are there compliance or certification concerns when substituting the TCND5000 for the TCND3000?

A: Both components maintain ROHS3 compliance and REACH Unaffected status. No compliance barriers exist for substitution from a regulatory standpoint.

Q: What should be verified before implementing the TCND5000 as a replacement?

A: Verify mechanical compatibility with the Module package format, confirm PCB layout accommodates the different package dimensions, and validate that the extended sensing distance range (2-25mm versus 10-20mm) aligns with application requirements.
