Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the THCS251 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Data Rate: 2.4Gbps
• Function: Serializer/Deserializer
• Input Type: CML, LVCMOS
• Output Type: CML, LVCMOS
• Number of Inputs: 1
• Number of Outputs: 1
• Voltage - Supply: 1.7V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 64-VFQFN Exposed Pad
• Supplier Device Package: 64-QFN (9x9)
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

The THCS251-B meets all critical electrical and mechanical parameters required for direct substitution. While the THCS251-B is supplied by CEL with active product status and includes additional compliance certifications (RoHS3, REACH), the core functional specifications remain identical to the original THCS251.

Parameter Comparison

Engineering Selection Recommendations

The THCS251-B is a direct parametric equivalent to the THCS251 and is suitable for applications requiring replacement of the obsolete THCS251. The THCS251-B maintains identical electrical specifications and physical packaging, ensuring pin-for-pin and functional compatibility.

The THCS251-B offers the advantage of active product status, providing improved long-term availability and supply chain stability compared to the obsolete THCS251. The THCS251-B includes RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for component procurement.

Selection between THCS251 and THCS251-B should be based on supply availability, inventory requirements, and regulatory compliance mandates of the end application.

Frequently Asked Questions (FAQ)

Q: Can THCS251-B be used as a direct replacement for THCS251?

A: Yes. The THCS251-B meets all critical electrical and mechanical parameters of the THCS251, including data rate (2.4Gbps), signal types (CML/LVCMOS), supply voltage range (1.7V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and package configuration (64-QFN 9x9). Pin-for-pin and functional compatibility is maintained.

Q: What is the difference between THCS251 and THCS251-B?

A: The primary differences are manufacturer source (THine Solutions, Inc. versus CEL), product status (Obsolete versus Active), and compliance certifications. The THCS251-B includes RoHS3 compliance and REACH unaffected status. All functional and electrical specifications are identical.

Q: Why is the THCS251 listed as obsolete?

A: The THCS251 has reached end-of-life status with THine Solutions, Inc. The THCS251-B represents the active equivalent part available through alternative supply channels.

Q: Are there packaging differences between THCS251 and THCS251-B?

A: Both parts use identical package specifications: 64-VFQFN Exposed Pad with 64-QFN (9x9) supplier device package. Moisture sensitivity level (MSL 3, 168 Hours) is also identical. The THCS251-B is supplied in Tray packaging format.

Q: What supply voltage range does the THCS251-B support?

A: The THCS251-B supports a supply voltage range of 1.7V ~ 3.6V, identical to the THCS251.

Q: Is the THCS251-B suitable for -40°C to 85°C operating temperature applications?
