THCV241A V-by-One® HS Serializer Equivalent & Substitute Parts

Part Overview

The THCV241A is a 4Gbps serializer interface IC manufactured by THine Solutions, Inc., designed for high-speed video signal serialization applications. This active product converts 6 CMOS inputs to 2 V-by-One®HS outputs in a 40-QFN (5x5) surface mount package. The part is ROHS3 compliant and qualified for industrial temperature ranges (-40°C to 105°C). Identifying equivalent and substitute parts is essential for supply chain continuity, inventory optimization, and design flexibility when the primary part number becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitute parts for the THCV241A are determined by strict equivalence across the following critical parameters:

Serializer Function: Both main and substitute parts must perform 6-to-2 CMOS-to-V-by-One®HS serialization
Data Rate: 4Gbps operation capability is mandatory
Input/Output Configuration: 6 CMOS inputs and 2 V-by-One®HS outputs
Supply Voltage Compatibility: Multi-rail voltage support (1.1V–3.6V range)
Operating Temperature Range: -40°C to 105°C industrial grade
Package Specification: 40-QFN (5x5) with exposed pad, surface mount
Compliance Standards: ROHS3 compliance and MSL 3 rating

The THCV241A-B is a parametric equivalent manufactured by the same supplier (THine Solutions, Inc.) that meets all electrical and mechanical specifications required for direct substitution in applications using the THCV241A.

Engineering Selection Recommendations

Both THCV241A and THCV241A-B are active products from THine Solutions, Inc., with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on:

Inventory Availability: THCV241A-B currently has higher stock availability (1372 pcs vs. 1025 pcs)
Supply Chain Requirements: Both parts share the same base product number (THCV241) and are sourced from the same manufacturer
Regulatory Compliance: Both meet ROHS3 requirements and MSL 3 moisture sensitivity specifications for industrial applications
PCB Design: No design modifications are required when substituting between these parts; pin configuration, package footprint, and electrical characteristics are identical

Frequently Asked Questions (FAQ)

Q: Can THCV241A-B be used as a direct replacement for THCV241A?

A: Yes. The THCV241A-B is a parametric equivalent with identical electrical specifications, package configuration, and compliance certifications. No circuit modifications or PCB redesign is required.

Q: Are there differences in the ECCN classification between these parts?

A: Yes. THCV241A carries ECCN 5A991B1, while THCV241A-B carries ECCN EAR99. Verify export compliance requirements for your specific application and destination.

Q: What is the significance of the "-B" suffix in THCV241A-B?

A: The "-B" suffix indicates a variant within the same base product family (THCV241). Both variants maintain identical functional and electrical parameters, with differences limited to manufacturing lot or compliance classification.

Q: Are the package dimensions and pin assignments identical?

A: Yes. Both parts use the 40-QFN (5x5) package with exposed pad, identical pin assignments, and surface mount configuration. PCB footprints are interchangeable.

Q: What is the MSL 3 moisture sensitivity rating?

A: MSL 3 indicates the component can be stored for up to 168 hours at 85°C and 85% relative humidity before soldering. Both parts carry this identical rating and require standard moisture control during handling and assembly.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametrically equivalent with identical electrical and mechanical specifications, they can be used interchangeably in the same design and production environment.
